Parts of the ECMO Circuit

Cardiogenic shock can originate from a variety of conditions, including LV, RV, or biventricular failure. Typical causes of cardiogenic shock are listed in Table 3, and a detailed review of published studies on each etiology can be found in our previously published work (36). Survival to discharge in cardiogenic shock due to acute myocardial infarction ranges from 19.2% (37) to 87.5% (38). Survival outcomes range from 47% (22) to 83.3% (39,40) for myocarditis and 57% (41) to 100% (42) for pulmonary embolism. VA-ECMO for acute rejection of cardiac allograft can be used as a preemptive measure, with a 79% rate of survival to discharge or as a salvage strategy with survival rate of 14% (43). Reports of successful ECMO use in drug overdose or drug intoxication exist, but are associated with severe depression of cardiac function (33).The most important determinant of outcome is time to basic life support. Early chest compressions influence all subsequent interventions. Immediate bystander CPR or a no-flow time <5 min are prerequisites for ECPR (4). The interval from the arrest to the beginning of CPR should be considered a no-flow period, whereas time on CPR is a low-flow period (28) with suboptimal circulation. The probability of survival with a good neurological outcome declines rapidly with each minute of conventional CPR. When ECPR is delayed until refractory cardiac arrest, defined as no response to resuscitation efforts after 30 min of conventional CPR, survival is extremely poor (29). Veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) is indicated as a haemodynamic rescue strategy in decompensated acute or chronic heart failure presenting as cardiogenic shock A veno-arterial (VA) ECMO that is applied in the case of a cardiogenic shock due to left ventricular (LV) failure On the other hand, in a patient with cardiogenic shock, VA-ECMO, which is administered by..

Extracorporeal membrane oxygenation: indications, technique and contemporary outcomes | Heart

An integral heat exchanger is included with the membrane oxygenator. Thus, a patient may be warmed or cooled as necessary. This may obscure the presence of a “fever” and make the recognition of an infection more difficult. Should ECMO be used for a patient after an anoxic insult, maintaining a temperature no higher than 36°F for up to 24 h might be of value (62).Many topics surrounding VA-ECMO use in cardiology are heavily debated. We discuss several of particular importance. ECMO may be veno-arterial (V-A) or veno-venous (V-V). The cannulae site can also vary and can be centrally located for V-A V-A ECMO is most like the heart-lung machine used during heart surgeries ECMO Initiation Surgical Team 30. VA ECMO VV vs. Selection of Technique 31. Usually for cardiac ECMO May convert VV to VA ECMO

Ischemic and hemorrhagic stroke occur in approximately 4% of VA ECMO patients (66). The rate of stroke varies by indication and cannulation technique. Ischemic stroke is most common in ECPR patients, diagnosed in 7% of successful resuscitations (66). Cannulation via the carotid artery triples the risk of ischemic stroke compared with femoral artery cannulation (67). One in 4 cerebral ischemia patients on VA-ECMO survive, whereas only 1 in 10 cerebral hemorrhage patients survives (68), usually with neurological deficit. Cognitive function should be monitored continuously in ECMO patients. ECMO - The Basics What It Is Prolonged form of bypass used to support patients w/ potentially reversible respiratory or cardiac failure unresponsive to maximal conventional therapy Veno-venous.. PulmCCM is an independent publication not affiliated with or endorsed by any organization, society or journal referenced on the website. (Terms of Use | Privacy Policy)Increasingly, VA-ECMO is being used during initial resuscitation from cardiac arrest. ECPR, the acronym by which this modality is known, is the application of rapid-deployment ECMO to provide circulatory support in patients who fail to achieve a sustained return of spontaneous circulation (ROSC) (defined as 20 consecutive minutes without a need for chest compressions by conventional CPR) (26). Use of ECMO initiated for low cardiac output following sustained ROSC is not considered ECPR (27). This important distinction is often neglected in published reports, making outcome analysis difficult. A recent prospective cohort study of in- and out-of-hospital ECPR in selected patients boasted 54% survival to discharge with full neurological function (6).

VA-ECMO–dependent increases in LV end-diastolic, left atrial, and pulmonary capillary wedge pressures can be mitigated by decreases in systemic vascular resistance or improvements in ventricular contractility (12). However, subtle increases in LV end-diastolic volume can be associated with substantial increases in LVEDP due to the nonlinear end-diastolic PV relationship (Figure 4) (12). While VA-ECMO is potentially a life-saving technique, results are sometimes mitigated, emphasising the need for selecting the right indication in the right patient Transplant organs salvaged by VA-ECMO show exceptional promise. Single centers demonstrated that organs (kidney, liver) perfused by VA-ECMO after cardiac death have the same transplantation outcomes as do those procured after brain death, the current gold standard for posthumous donor harvesting (81). ECMO maintains an organ at body temperature and delivers perfusate to a mechanically ventilated “lung in a box” or a beating “heart in a box” to allow for organ improvement and assessment before transplantation with promising results (82,83).Patients on ECMO may or may not require ventilator support. Because ECMO provides up to full gas exchange, the conscious patient in cardiogenic shock can breathe spontaneously while on ECMO, regardless of respiratory function. However, ventilator support may be necessary for airway protection in patients requiring sedation, such as cardiac arrest patients. Most centers use low tidal volume ventilation (3 to 5 ml/kg) to reduce the risk of lung injury. Protective mechanical ventilation settings include a rate of <8/min, positive end-expiratory pressure of 10 to 15 Torr, fraction of inspired oxygen <0.40, and low tidal volume (61).

Cardiac arrest on ECMO

During venoarterial extracorporeal membrane oxygenation (VA-ECMO), respiratory monitoring is difficult to perform because the extracorporeal support replaces completely the heart and lung function The aforementioned physiology is also important when weaning a patient from VA-ECMO [17]. If RV or biventricular failure is present, it is imperative that the clinician recognize that increased venous return may have disastrous hemodynamic consequences. Such patients should have their RV function optimized with careful consideration for each of the following: volume status, inotropic support, pulmonary vasodilators, and pulmonary mechanics including the mode of and settings of mechanical ventilation [18]; consultation with a specialist in the management of pulmonary hypertension may even be beneficial.

Data regarding the efficacy of VA-ECMO are Citation: Guglin, M. et al. (2016). VA-ECMO in Cardiogenic provided almost exclusively by single-center, retrospective analyses ECMO (AKA extracorporeal life support or ECLS) is a short-term means of providing life support in people who are Specifically, ECMO infuses oxygen into the blood and removes carbon dioxide After appropriate patient selection and team notification, a primary ECMO physician directs the team, performs cannulation, and leads multidisciplinary patient management. Critical care nurses manage intravenous lines, administer medications, monitor pressure and electrocardiogram data, request laboratory tests, and document care. Specifically, a nurse places defibrillator pads on the chest, ensures adequate intravenous access, prepares heparin, and types and crossmatches for red blood cells, fresh frozen plasma, and platelets. The perfusionist provides cannulas, primes and sets up the ECMO circuit, and initiates support after the circuit is completed. After support is initiated, cannula sites are secured with bands, a sterile dressing is placed, and x-rays are taken to check for proper cannula locations. Continuous ECMO support requires nursing at 1:1 or 1:2 ratios, and ECMO physicians should be in the immediate vicinity and should provide continuous medical management.

ECPR should be attempted early after cardiac arrest, rather than after the complete failure of traditional measures (30). Studies suggest 21 min of conventional CPR before initiation of extracorporeal life support (VA-ECMO), with ECPR preparation in the first 10 min of CPR and cannulation within 20 min of collapse (Figure 5) (31).1Department of Thoracic and Cardiovascular Surgery, School of Medicine, Konkuk University Chungju Hospital, Konkuk University, Chungju-si, Chungbuk, Republic of KoreaA fantastic model – borne from the principles Arthur Guyton – was formed by Sunagawa et al [3]; very recently, this model was further developed by Sakamoto and colleagues as a framework for understanding VA-ECMO [4]. Before turning to these advanced concepts, a basic review of venous return and cardiac function is warranted.Sepsis has historically been considered a contraindication to ECMO. The standard explanation has been that sepsis is associated with multisystem organ failure and poor survival, regardless of extracorporeal life support. However, the lack of difference in survival between the septic and nonseptic groups indicated that infection does not adversely affect the outcomes on ECMO (10). ECMO can be beneficial in selected septic patients with sepsis-related LV dysfunction.

In most studies about VA ECMO, advanced age is regarded as a main significant risk factor and contraindication to VA ECMO treatment; however, a more important factor is physiologic status, but not age. Therefore, patients of advanced age should not be excluded from the chance of recovery with VA ECMO treatment. Additionally, advanced age could be regarded as a major risk factor for VA ECMO; however, it should not be considered an absolute contraindication to VA ECMO.

ECMO, which stands for Extracorporeal Membrane Oxygenation, is a procedure during which blood oxygenation and cardiac function are performed by a mechanical pump outside the body 1. Increase in forward flow by introducing inotropes or devices such as Impella (Abiomed, Danvers, Massachusetts) or intra-aortic balloon pump (IABP).As the LV recovers, it starts ejecting blood it receives from the pulmonary circulation. Forward flow of deoxygenated blood from failing native lungs mixes unpredictably with retrograde flow from the oxygenator, which can result in inadequate delivery of oxygenated blood into the aortic arch, resulting in upper body and brain hypoxia. This phenomenon, known as Harlequin syndrome, may result in cyanosis of the upper extremities while the lower extremities appear pink. Saturation monitoring for Harlequin syndrome is performed at the right hand, forehead, nose, or right ear, and arterial blood gas should be obtained from a right arm arterial line. VA-ECMO is complex, and the data may (1) reflect physicians' hesitance to cede authority to presumably less knowledgeable patients and surrogates, (2) stem from a stewardship of resources..

Patients requiring ECMO support need the highest level of intensive care from a multidisciplinary team. Because the initiation of ECMO therapy is time sensitive, numerous interventions take place simultaneously or in rapid succession until the patient’s condition is stabilized. Triage by ECMO experts to confirm appropriate candidates is necessary to avoid futile application of the therapy. Core ECMO teams generally consist of trained and dedicated physicians, an ECMO coordinator, nurse practitioners, staff nurses, perfusionists, and respiratory therapists (72). The ELSO guidelines recommend that program directors should be a board-certified critical care specialist; cardiovascular specialist; a thoracic, vascular, or trauma surgeon; cardiac and critical care anesthesiologist; or other board-certified specialist with training and experience in ECMO therapy (70,73,74). ECMO specialists should be available 24/7 to support the team and complete daily patient management. In some hospitals, emergency room physicians become an integral part of the program, fully capable of initiating ECMO (75). ECMO - . introduction. ecmo is frequently instituted using cervical cannulation, which can be performed under local. ECMO et assistance pour insuffisance circulatoire aigue.. Patients on VA-ECMO are typically anticoagulated and prone to bleeding. For optimal blood oxygen saturation, hemoglobin should be maintained between 8 and 10 mg/dl. Transfusions may be required, but they may allosensitize a potential transplant candidate and cause transfusion-related acute lung injury.

In a VA-ECMO circuit, deoxygenated blood is pulled from the venous circulation by a pump via a large-bore cannula. Patients may be cannulated centrally (Central Illustration, A) or peripherally.. The closed ECMO circuit withdraws deoxygenated blood from the venous system through 1 or multiple drainage cannulae, pumps the blood through an oxygenator where gas exchange occurs, and returns the blood to the venous (VV) or arterial (VA) circulation through a reinfusion cannula (Figure 2) (7). Whereas VV-ECMO replaces failing lungs, VA-ECMO provides both respiratory and hemodynamic support (i.e., replaces heart and lung). The focus of this paper is VA-ECMO.ECMO is a portable modification of cardiopulmonary bypass capable of supporting critically ill patients with refractory cardiopulmonary failure for days to weeks (4). Although available for over 40 years, ECMO was initially used primarily in neonatology. ECMO, predominantly venovenous (VV), was first used in adults with severe but potentially reversible lung disease, such as influenza pneumonia and adult respiratory distress syndrome. Over the past decade or so, the technology has gained momentum in adult cardiology. VA-ECMO — venoarterial extracorporeal membrane oxygenation..

Increasingly, VA-ECMO is being used during initial resuscitation from cardiac arrest. VA-ECMO for acute rejection of cardiac allograft can be used as a preemptive measure, with a 79% rate of survival.. Staffing of the ECMO team varies considerably among institutions; case volume and other responsibilities are the primary determinant. Physician availability 24 h a day to cannulate and manage ongoing cases requires a minimum of 3 physicians, but this number depends largely on their total responsibilities while on duty. If the physician is also responsible for other critically ill patients, post-LVAD or post-transplant cases, the acuity increases substantially.

Venoarterial ECMO for Adults JACC: Journal of the American College

VA ECMO is a powerful tool that needs to be used judiciously. As we gain proficiency, the lack of prospective randomized studies or a useful classification system and areas of uncertainty create multiple challenges. Appropriate infrastructure, appropriate skill set of team members, and thorough assessment of each ECMO candidate, with an evaluation of indications and contraindication to ECMO support, are key steps to ensure optimal outcomes.Venous return, however, is only half of the cardiovascular story as valvular competence, heart rate and rhythm, contractility, diastolic properties and afterload also mediate circulatory homeostasis. All of these properties together are described by the summative cardiac function curve which is also known as the Frank-Starling curve or cardiac response curve [9-11]. The intersection of cardiac function and venous return defines the central venous pressure [12] which is one determinant of IVC volume [13].

ELSO provides detailed guidelines for the transport of patients supported by ECMO (2). The establishment of advanced cardiac care systems that are designed with high-volume hub hospitals integrated with emergency medical systems and community-based spoke centers may affect the outcomes of patients with profound cardiac or pulmonary failure (71). A hub-and-spoke regional network consists of 3 levels of care. Level 1 centers provide all aspects of care, including transplant, durable VADs, and short-term circulatory support, including ECMO. Level 2 centers provide cardiac catheterization and surgery, with the capability of short-term mechanical support. Level 3 centers provide resuscitation, with medical therapy for stabilization (Figure 7) (76). Bringing together these different-level centers to provide ECMO support requires commitment and communication from a variety of health care professionals. Protocols that define communications, triage and patient selection, patient management, and the transport process must be in place and strictly adhered to by all participating centers so that debate is minimized during the triage process.

Activation of the ECMO team requires (except in emergency circumstances) a priori interactive discussion between team members to make an initial assessment regarding the probability of success based upon the clinical scenario, institutional capabilities, and survival estimates. After the majority of team members agree to proceed, the inserting physician needs to coordinate the process with the perfusionists or catheterization laboratory nurses and arrange for a critical care bed and an advanced paramedic transport unit, when indicated.ECMO is a complex and high-risk therapy that should be managed at experienced centers with appropriate personnel and sufficient resources to ensure it is used effectively (70,71). New ECMO programs should partner with larger and more experienced programs to not only learn from their personnel, but to acquire sample care plans, nursing protocols, and policies. Advanced heart failure care programs that offer multiple forms of mechanical circulatory support, heart and lung transplant, and advanced medical therapy at high-volume tertiary care centers should serve as hub ECMO centers. All centers participating in such a hub-and-spoke system of care should strictly adhere to written standardized protocols that detail criteria for the initiation of ECMO support, contraindications, follow-up care, and exit strategies.We are committed to sharing findings related to COVID-19 as quickly and safely as possible.

VA ECMO Cannulation Technique via the Axillary Artery and CTSNe

    Insufficient Flow

Perhaps the most memorable patient of both my pulmonary and critical care fellowships was that of a very young woman who suffered from propofol-related infusion syndrome [PRIS]. As a consequence of PRIS, she endured multiple cardiac arrests and was placed on Veno-Arterial Extra-Corporeal Membrane Oxygenation [VA-ECMO] during cardiopulmonary resuscitation. Because of the rapid resuscitation she received from my colleagues, she survived to discharge – neuro-cognitively intact – despite spending an entire evening without cardiac activity. The details of her case may be reviewed here [1]. The aforementioned use of VA-ECMO highlights its life-preserving capability, and underscores the importance of its hemodynamic workings. Cannulation Strategies for VA ECMO. VA ECMO Distal Perfusion to Minimize Vascular Complications. Hemodynamic Effects of Peripheral VA-ECMO Although VA ECMO was originally applied for respiratory support, its main appli-cation is nowadays as a circulatory support. Currently VA ECMO is mainly used to sustain circulation during cardiac failure The left heart faces an identical physiology with the pressure head for venous return originating within the pulmonary circuit [14]; pulmonary venous return is then mediated by the cardiac function of the left heart and left atrial pressure is determined at the physiological intersection thereof. As above, the slope of the cardiac function curve is determined not just by contractility, but by multiple variables one of which is afterload [10]. Thus an increase in left heart afterload will impair – shift down – the slope of the cardiac function curve.

Worked on this over the summer of 2013 with Ming Jack Po Usually, an ECMO flow of 50 to 70 ml/kg/min (∼4 to 6 l/min) is sufficient for full markedly decreased and the aorta is filled by retrograde flow from the arterial ECMO cannula. Therefore, the afterload faced by the LV is increased. This may result in an elevated LVEDP, elevated pulmonary capillary wedge pressure, and ultimately pulmonary congestion. In this situation, the use of inotropes may be considered or, in unusual circumstances, an interatrial balloon septostomy can be performed to shunt blood from the LA to the right atrium and reduce the elevated left-sided pressures. Multiple approaches to LV unloading or “venting” are reviewed in the Pathophysiology section. Another disadvantage to VA bypass is that any particles, bubbles, or emboli that may be infused into the arterial or venous circuit can result in an adverse cerebral event. Finally, the decreased flow through the lungs may permit the development of microvascular intrapulmonary thromboses, which may further worsen the pulmonary pathology.Limited vascular access (severe peripheral arterial disease, extreme obesity, amputated limbs, among others) Venoarterial (VA) ECMO can be used for heart and lung support, while venovenous (VV) ECMO is used for lung This type of ECMO takes blood out of a large vein and returns it into a large artery, allowing..

Cardiac Surgery - Extracorporeal Membrane Oxygenation (ECMO

  1. Both VV- and VA-ECMO can be used to treat refractory acute respiratory failure. VA-ECMO (in contrast to VV-ECMO) can provide complete circulatory support. Compared with other temporary mechanical circulatory support devices used to support patients with refractory cardiogenic shock, VA-ECMO addresses both right ventricular (RV) and left ventricular (LV) dysfunction, systemic oxygenation (pO2), and acid-base balance via modulation of the partial pressure of CO2. The circuit configuration (Figure 2) permits the withdrawal and pumping of desaturated blood from the right atrium or a central vein, with nonpulsatile pump outflow directed toward the membrane oxygenator then guided via an outflow cannula to a systemic artery (e.g., femoral or subclavian artery).

How Extracorporeal Life Support (ECMO) Work

on VA ECMO, forward flow results from what ? ECMO pump contribution + LV C.O. During VA ECMO, blood is returned to the aortic arch, and is directed towards the aortic valve The hemodynamic condition of the LV in all types of cardiogenic shock is best illustrated by the pressure-volume (PV) loop. This loop depicts the 4 phases of a single cardiac cycle and provides information about contractile and relaxation properties, cardiac work, and myocardial oxygen consumption (9–11). Typically, in cardiogenic shock, independent of underlying etiology, LV contractility, reflected by Emax, defined as the maximum slope at the end-systolic PV point, is reduced and LV end-diastolic pressure (LVEDP) is increased. Although there are differences in the magnitude of effect on stroke volume and LV stroke work with the different types and severities of cardiogenic shock, these indexes are also typically reduced (Figure 3) (10). Different cardiac effects using PV loops with the different mechanical support devices have been reported (11). ECMO is actually a misnomer. Extra-corporeal life support (ECLS) is probably a better term. If a catheter is placed in a major artery and a major vein (VA ECMO), the patient can be provided with full..

Depending on distance and the size of the metropolitan area, ground ambulance, helicopter, or fixed-wing aircraft may be used. Ideally, the hub hospital has helicopter service readily available and can provide timely transport. For transport of a stable patient to the hub hospital, a ground ambulance may be best if the distance is not excessive (78). In the regional program in Oklahoma, 250 patients from 4 different states have been transported by multiple modes of transportation. (PLO)- ECMO là kỹ thuật cao nhất trong hồi sức cấp cứu nhi khoa. Sau bảy ngày điều trị, hiện bệnh nhi T. đã cai được ECMO, cai máy thở, bước đầu có thể tiếp xúc và nói chuyện với mọi người The most likely infectious complications of VA-ECMO are bacteremia and sepsis, with longer ECMO runs associated with higher infection rates. More than 53% of adults acquire an infection within 14 days of ECMO initiation. Mortality in patients with infectious complications reaches 60%. The sterile technique during cannulation is of paramount importance, especially considering the urgent or emergent nature of the procedure.ECMO is often instituted without adequate time for a detailed discussion between the health care team and the patients and their families. This can result in unclear perceptions of goals, poor understanding of limitations, and cases of futility and situations mandating withdrawal. An ECMO-specific consent form should be considered by institutions. In situations involving disagreement, early involvement of the ethics team, palliative care team, and hospital leadership may be beneficial (79).

Our study has several limitations. First, it was conducted at a single institution, which limited the generalizability of study results. Secondly, our study population was relatively small and had multiple underlying diseases indicated for VA ECMO. Thirdly, despite a study about VA ECMO, a relatively small number of patients with refractory septic shock were enrolled in the study. Fourthly, since our study only focused on VA ECMO, it is difficult to generalize our results to other forms of ECMO, such as VV ECMO. Further studies using various forms of ECMO are warranted. Our study only focused on initial modalities at the decision point of ECMO, and long-term outcomes were not evaluated. evaluated. Fifthly, serum biomarkers, such as brain natriuretic peptide, were not measured in our study. The brain natriuretic peptide is known as a predictor of the outcomes after severe cardiac failure [78]. Further studies are needed to determine whether our results could be accurately applied to such patients. Finally, we performed retrospective analysis, so that additional prospective multicenter studies are needed to confirm our results. Future research should develop more simplified VA ECMO scoring systems with a larger sample size to accurately predict VA ECMO mortality.Dr. Zucker has reported that he has served on the scientific advisory board for and received honoraria from Alnylam and Pfizer.

Hospital administration should be committed to the support of the program’s initiation costs, but should also be aware that if the volume of cases exceeds the estimate, more equipment and personnel resources will be needed.

Complications With VA-ECMO Suppor

The ECMO support program was first initiated at a single medical center in January 2006, and VA ECMO was performed on 135 adult patients with primary cardiogenic shock between January 2010 and December 2014. All the patients were aged ≥18 years. They received VA ECMO at a single medical center by a single ECMO team directed mainly by cardiothoracic surgeons, which was performed for refractory cardiogenic shock and various medical conditions (Table 1). To avoid selection bias, this study excluded patients with respiratory failure undergoing VV ECMO. ELSO indications for VA ECMO in adults were applied; however, advanced age was not considered an absolute or relative contraindication. Successful weaning was defined as weaning from ECMO followed by survival for more than 48 hours. Survival was defined as weaning from ECMO and improvement in an underlying clinical condition followed by discharge from the hospital. This study was approved by the Institutional Review Board (2013-105), and informed consent was waived due to its retrospective study design. Ispra (VA) (IT).

The classification of indications for VA-ECMO was inherited from the pediatric past, with heavy emphasis on congenital heart disease, which accounts for only fraction of VA-ECMO cannulations. ELSO divides cardiac runs by the following indications: cardiac arrest, cardiogenic shock, acute myocarditis, cardiomyopathy, congenital, and miscellaneous. From 1990 to 2016, according to the 2017 ELSO report, 4% of cardiac runs were done for congenital heart disease, 5% for cardiac arrest, 2.2% for myocarditis, 6.7% for cardiomyopathy, 24.4% for cardiogenic shock, and 58% for other indications (2).

  2. VA-ECMO is hemodynamically distinct from veno-venous extra-corporeal membrane oxygenation [VV-ECMO]. The latter is often used as a salvage therapy for severe ARDS in patients with preserved cardiac function as reviewed here [2]. VV-ECMO removes venous blood, performs gas exchange through an external circuit and then returns the blood back to the venous system. By contrast, VA-ECMO removes venous blood, performs gas exchange through an external circuit, and then returns the ‘revitalized’ blood to the arterial tree. VA-ECMO, therefore, bypasses the heart and the lungs completely and may be used in advanced cardiac-arrest algorithms as described in the case above. Importantly, should VA-ECMO be employed in advanced cardiac failure, the hemodynamic repercussions must be anticipated; this may be accomplished using the paradigm given to us by Arthur Guyton.

VA-ECMO for septic shock

Severe irreversible noncardiac organ failure limiting survival (e.g., severe anoxic brain injury or metastatic cancer)ECMO provides continuous blood flow. Any pulsatility, if present, is created by the residual function of the LV. In severe cases of cardiogenic shock or in the presence of cardiac tamponade, Korotkoff sounds may be absent and only mean blood pressure can be measured, necessitating use of an arterial line. As cardiac function improves, pulsatility on the arterial tracing is increasingly pronounced and may be a sign of recovery.

Wir haben gerade eine große Anzahl von Anfragen aus deinem Netzwerk erhalten und mussten deinen Zugriff auf YouTube deshalb unterbrechen.3Department of Thoracic and Cardiovascular Surgery, College of Medicine, Hallym University Sacred Heart Hospital, Hallym University, Gyeonggi-do, Republic of KoreaSuccessful weaning was defined as weaning from ECMO support, followed by survival for more than 48 hours [33]. All patients received ECMO for at least 48 hours before weaning was attempted. The criteria included SvO2 ≥ 70%, hematocrit of 30%–35%, absence of definite bleeding foci, tamponade or left heart distension, left ventricular ejection fraction ≥ 35%, and normal blood lactic acid levels. Furthermore, it was essential to comprehensively identify that the patient’s organ function fully recovered and stabilized from underlying disease. ECMO weaning was attempted when the patient on ECMO was hemodynamically stable by the minimal ECMO blood flow (<20% of total flow) with good recovery of myocardial contractility evidenced by echocardiography. The ECMO blood flow was decreased by 500 to 1,000 mL/min for ECMO weaning. Once cardiac pulsatility and contractility improved, ECMO flow was reduced after optimizing inotropic infusion and ventilator setting. Finally, ECMO was withdrawn when sustained stability was noted in the patient’s hemodynamic status [34–38].

According to the Extracorporeal Life Support Organization (ELSO), an international voluntary registry, the number of adult cardiac ECMO runs increased 1,180% in the last decade, from <200 between 1997 and 2007 to over 2,000 to date (Figure 1) (2). Likewise, the number of ECMO centers, which increased by 15% (from 115 to 131) from 1996 to 2006, rose by a staggering 133% (from 131 to 305) from 2006 to 2016.An organized system should consist of 3 levels of care. Level 1 centers (the hub) provide all aspects of care, including extracorporeal membrane oxygenation (ECMO), durable long-term ventricular assist devices (LVADs), right ventricular support (RV), and heart transplantation. Level 2 centers provide short-term care. Surgeons are available but not necessarily on site. Level 2 centers should house a catheterization lab and ECMO initiation or cannulation capabilities. Level 3 centers can provide diagnosis, resuscitation, hemodynamic monitoring, and stabilization with vasopressors and inotropes. LV = left ventricular. ECMO may be called for in 0.1 - 0.3 percent of COVID-19 cases, but its effectiveness in the pandemic is still in doubt. Given the risks involved, ECMO devices are rarely used, including in Russia In the absence of definitive results on the utility and cost effectiveness of ECMO, it becomes challenging to accept its widespread use, which may strain limited resources in certain communities. Local and state laws may need to be addressed to allow termination and withdrawal of patients from support by clinicians in case of proven futility, scenario of bridge to nowhere, or irreversible injury with discord between patient-patient surrogate and the clinical teams. Finally, thorny issues, such as whether hospitals without ECMO capability should be mandated to transfer patients to ECMO centers, need to be addressed.ECMO has become the preferred device for short-term hemodynamic support in patients with cardiogenic shock. Table 1 compares ECMO to other short-term devices. Most practicing cardiologists have not been trained on ECMO, prompting this comprehensive review.

Venous cannulas can be placed percutaneously in the majority of.. Investigators from the University of Michigan state that a pressure drop in the circuit should not exceed 100 mm Hg across the venous cannula and 300 mm Hg across the arterial side. The flow required for full support in an adult is about 60 cm3/kg/min. Not only are the length and diameter of the cannula important, but there are special flow characteristics for each cannula, that can be described by a pressure flow curve. A unique number, called a UM number (flow achieved at a pressure drop of 100 mm Hg across a cannula) may be used to describe the cannula and its flow characteristics (53).The choice of agent used for anticoagulation, as well as monitoring of the level of anticoagulation, varies from site to site. Heparin is the most common anticoagulant, used according to a standard weight-based protocol and monitored either by activated thromboplastin time, goal 50 to 75 s (1.5× to 2.5× baseline) or anti-factor Xa, goal 0.3 to 0.7 IU/ml. Some centers prefer to follow the activated clotting time, due to its bedside availability and rapid turnaround time, goal 180 to 220 s.

The use of IABP counterpulsation in VA-ECMO is debated in published reports, but is thought to enhance systolic unloading and improve the myocardial oxygen supply-demand ratio (17). Two studies demonstrated smaller LV dimensions and lower pulmonary artery pressures with VA-ECMO plus active IABP support (11,15). In a retrospective cohort study of 1,650 adult patients with cardiogenic shock from the nationwide Japanese national inpatient database, 28-day and in-hospital mortality were significantly lower with VA-ECMO plus IABP (48.4% vs. 58.2%; p = 0.001) than with VA-ECMO alone (55.9% vs. 64.5%; p = 0.004) (18). However, an observational meta-analysis of 16 studies showed a lack of survival benefit of VA-ECMO with concomitant IABP (19). To date, no randomized controlled trials have been performed to clarify the role of venting and the strategy (IABP vs. alternative devices) that best attenuates the VA-ECMO flow-dependent increase in LVEDP.Femoral vein to femoral artery is the most common approach. Nonemergent VA-ECMO patients may be considered for internal jugular vein to subclavian artery cannulation, termed the “sport model” (54,55). This development in technique moved nonemergent VA-ECMO cannulation sites from the groin (femoral) to the upper body (subclavian) vessels, facilitating ambulation (56,57). Ambulatory ECMO is particularly important in patients awaiting transplantation to reduce the risk of patients deconditioning as they await transplantation (58).Cannulation can be performed peripherally or centrally. Peripheral insertion may be quicker, but it is known to be associated with vascular compromise of the lower extremity due to the large size of the cannula, particularly in small women or in a high systemic vascular resistance (“clamped down”) state. It is generally stated that unless the vessel is at least 1 to 2 mm larger than the cannula, there is the risk of limb ischemia. This problem can be addressed by placing a small 6-F to 8-F antegrade sheath or introducer into the superficial femoral artery at the time of cannula insertion and diverting a small portion of the arterial return flow down the limb (reperfusion catheter).Specifically, with VA-ECMO, LV afterload increases, as reflected by the increase in effective arterial elastance, a known component of LV afterload, as depicted in Figure 4 (12). This contributes to an increase in LVEDP. In patients with significantly reduced ejection fractions at baseline, VA-ECMO may cause an increase in wall stress and oxygen demand, which impedes myocardial recovery and may precipitate progressive pulmonary edema and acute lung injury and worsen outcomes (13). This complication is generally referred to as LV distension or ECMO lung.

The use of extracorporeal membrane oxygenation (ECMO) in cardiovascular disease is soaring. After the landmark CESAR (conventional ventilatory support versus extracorporeal membrane oxygenation for severe adult respiratory failure) trial, in which ECMO appeared to be superior to the ventilator in the adult population (1), this modality has been increasingly popular.The negative impact of venoarterial extracorporeal membrane oxygenation (ECMO) on PV loop curves with a flow dependent increase in LVEDP (asterisks) and associated increase in effective Ea, as defined in Figure 2.

Mechanical Support for the Failing Right Ventricle in Patients With Precapillary Pulmonary

This video demonstrates VA ECMO using the right axillary artery and the right femoral vein. Thank you for the informative video. I cannulated one adult ECMO patient with axillary approach CO2 removal is primarily controlled by adjusting the rate of countercurrent gas flow through the oxygenator, otherwise known as the sweep speed (8). ECMO is extremely effective in removing CO2. CO2 is removed by diffusion. The sweep gas is typically 100% oxygen, and correction of respiratory acidosis can be rapidly achieved by increasing the sweep speed.As elaborated by the model put forth by Sakamoto et al., VA-ECMO short-circuits the normal hemodynamic path [4]. When VA-ECMO is initiated, blood is removed from the venous bed which attenuates mean systemic pressure and diminishes venous return to the right heart. Exogenous or endogenous adrenergic tone would tend to oppose this effect, but the flow at which venous blood is removed by VA-ECMO is a major determinant of the fall in venous return. Attenuated blood flow to the right heart would mitigate each of the following: right atrial pressure, IVC volume and pulmonary blood flow. These effects are important if a pulmonary artery catheter is employed; further, change in pulmonary blood flow may alter gas exchange within the native circuit [15].• Progress in durable mechanical circulatory support devices, which enables ECMO use as bridge to a left ventricular assist device (LVAD)

After blood passes through the external VA-ECMO circuit, it is returned to the arterial tree; the increase in arterial blood volume raises the afterload of the left ventricle [LV]. As a consequence, there is a shift of the LV cardiac function curve downwards and left atrial pressure, for any given degree of pulmonary venous return, is raised [4]. As VA-ECMO is often initiated in patients with poor, or absent LV function, this effect may be profound. However, as above, because pulmonary blood flow and pulmonary venous return are diminished, the rise in left atrial pressure is blunted. Nevertheless, acute pulmonary edema upon initiation of VA-ECMO is described [16].Lack of a solution (listed previously) or a potential to recovery should discourage ECMO initiation. The ECMO team should consider objectives (Table 2) and indications (Table 3) for VA-ECMO before patient cannulation: 1) cardiac arrest; 2) cardiogenic shock; 3) refractory ventricular tachycardia; 4) RV failure during LVAD support; and 5) failure to wean off cardiopulmonary bypass.

Speaker: Nadia Aissaoui, Paris, France Moderation: Peter Schellongowski, Vienna ECMO in immunosuppressed patients? Speaker: Peter Schellongowski, Vienna, Austria

Interestingly, an important prediction of the Sakamoto model is that left atrial pressure – and therefore the risk of pulmonary edema – will remain high in states of right ventricular [RV] failure, even when LV function is supra-normal [4]. As they offer no mechanistic explanation, it is tempting to speculate. While VA-ECMO lowers right atrial pressure, in RV failure it is possible that RV volume and pressure remain high despite blood being shunted to the arterial tree. Potentially, through ventricular interdependence, LV diastolic function is impaired and compounded by the rise in LV afterload imposed by VA-ECMO physiology. Thus, augmenting VA-ECMO flow will decongest the failing RV, but at the cost of raising the afterload of the LV. In such patients, then, it may be beneficial to consider a ventricular assist device [VAD] rather than ECMO [4].The indications for venoarterial (VA)-ECMO continue to evolve. Over the past decade, the primary indication shifted from post-cardiotomy shock (treated by surgeons) to multifactorial cardiogenic shock and/or cardiac arrest (treated in the setting of multidisciplinary teams including cardiologists or primarily by cardiologists) (Central Illustration). The proportion of post-cardiotomy shock patients supported on VA-ECMO decreased from 56.9% in 2002 to 37.9% in 2012. During this same period, the number of adult patients with cardiopulmonary failure supported on VA-ECMO substantially increased (3).If a patient improves on ECMO, weaning is the next step. ECMO flow is decreased by approximately 1 l/h over a period of 3 to 4 h, although slower rates of weaning at 0.5 l every 6 to 24 h have been reported as well (57). The patient should be able to maintain a mixed venous saturation >65%, and an arterial saturation of >90% with an ECMO flow <1.5 l/min. A bridge between the arterial and venous cannulae can be also used to completely separate patient circulation from the ECMO circuit without decannulation. If there are signs of decompensation, the bridge is clamped, and the patient is placed back on full support (63). Decannulation typically occurs in the catheterization laboratory or in the operating room.

Monitoring for increasing LVEDP may include serial physical examinations, chest radiographs, or Swan-Ganz catheter monitoring. Treatment of anticipated or observed increases in LV systolic and end-diastolic pressure includes venting or decompressing the LV. EVMS Critical care COVID-19 management protocol.
