ABSTRACT
BACKGROUND: The high-quality evidence on managing COVID-19 patients requiring extracorporeal membrane oxygenation (ECMO) support is insufficient. Furthermore, there is little consensus on allocating ECMO resources when scarce. The paucity of evidence and the need for guidance on controversial topics required an international expert consensus statement to understand the role of ECMO in COVID-19 better. Twenty-two international ECMO experts worldwide work together to interpret the most recent findings of the evolving published research, statement formulation, and voting to achieve consensus. OBJECTIVES: To guide the next generation of ECMO practitioners during future pandemics on tackling controversial topics pertaining to using ECMO for patients with COVID-19-related severe ARDS. METHODS: The scientific committee was assembled of five chairpersons with more than 5 years of ECMO experience and a critical care background. Their roles were modifying and restructuring the panel's questions and, assisting with statement formulation in addition to expert composition and literature review. Experts are identified based on their clinical experience with ECMO (minimum of 5 years) and previous academic activity on a global scale, with a focus on diversity in gender, geography, area of expertise, and level of seniority. We used the modified Delphi technique rounds and the nominal group technique (NGT) through three face-to-face meetings and the voting on the statement was conducted anonymously. The entire process was planned to be carried out in five phases: identifying the gap of knowledge, validation, statement formulation, voting, and drafting, respectively. RESULTS: In phase I, the scientific committee obtained 52 questions on controversial topics in ECMO for COVID-19, further reviewed for duplication and redundancy in phase II, resulting in nine domains with 32 questions with a validation rate exceeding 75% (Fig. 1). In phase III, 25 questions were used to formulate 14 statements, and six questions achieved no consensus on the statements. In phase IV, two voting rounds resulted in 14 statements that reached a consensus are included in four domains which are: patient selection, ECMO clinical management, operational and logistics management, and ethics. CONCLUSION: Three years after the onset of COVID-19, our understanding of the role of ECMO has evolved. However, it is incomplete. Tota14 statements achieved consensus; included in four domains discussing patient selection, clinical ECMO management, operational and logistic ECMO management and ethics to guide next-generation ECMO providers during future pandemic situations.
ABSTRACT
Background: The Extracorporeal Life Support Organization Supplies Platform (https://Supplies.ELSO.org) was created out of Extracorporeal Membrane Oxygenation (ECMO) disposable product shortage prior to and during the Coronavirus Disease 2019 (COVID-19) pandemic. This novel Platform supports Centers in obtaining disposables from other Centers when alternative avenues are exhausted. Methods: Driven by the opportunity for increased patient care by using the product availability of the 962 ELSO centers worldwide was the motivation to form an efficient online supply sharing Platform. The pandemic created by COVID-19 became a catalyst to further recognize the magnitude of the supply disruption on a global scale, impacting allocations and guidelines for institutions, practice, and patient care. Conclusions: Records kept on the Platform website are helpful to the industry by providing insights into where difficulties exist in the supply chain for needed equipment. Yet, the common thread is awareness, of how critical situations can stretch resources and challenge our resolve for the best patient care. ELSO is proud to support member centers in these situations, by providing a means of attaining needed ECMO life support products to cover supply shortages.

OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) systems have continued to evolve and improve with the development of smaller and portable systems. The Cardiohelp (Maquet Getinge Cardiopulmonary AG, Rastatt, Germany) portable life support device is a compact ECMO system used widely in adults and for ECMO transport. Reports of its use in neonatal and pediatric centers remain limited. In this single-center retrospective review, we describe our institutional experience with the Cardiohelp. DESIGN: Single-center retrospective review. SETTING: Neonatal ICUs and PICUs in a tertiary-care children's hospital. PATIENTS: Seventeen pediatric patients on ECMO. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Median (interquartile range, IQR) of patient age was 0.5 years (0-7 yr). Eleven of 17 patients were on veno-arterial ECMO, five on veno-venous ECMO, and one on veno-venoarterial ECMO. All veno-venous and veno-venoarterial runs ( n = 6) were accomplished with bicaval, dual-lumen cannulae. Median duration on Cardiohelp was 113 hours (IQR 50-140 hr). Median anti-Xa level for patients was 0.43 IU/mL (IQR 0.35-0.47 IU/mL), with median heparin dose of 23.6 U/kg/hr (IQR 17.6-28.1 U/kg/hr). Median plasma-free hemoglobin was 41.4 mg/dL (IQR 30-60 mg/dL). Circuit change was required in three cases. Fourteen patients survived ECMO, with 13 patients surviving to discharge. CONCLUSIONS: We have used the Cardiohelp system to support 17 neonatal and pediatric ECMO patients, without complications. Further studies are warranted to compare complications, outcomes, and overall cost with other institutions and other existing ECMO systems.

The use of extracorporeal membrane oxygenation (ECMO) is growing rapidly in all patient populations, especially adults for both acute lung or heart failure. ECMO is a complex, high risk, resource-intense, expensive modality that requires appropriate planning, training, and management for successful outcomes. This article provides an optimal approach and the basic framework for initiating a new ECMO program, which can be tailored to meet local needs. Setting up a new ECMO program and sustaining it requires institutional commitment, physician champions, multidisciplinary team involvement, ongoing training, and education of the ECMO team personnel and a robust quality assurance program to minimize complications and improve outcomes.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a supportive therapy used in the most severe forms of acute respiratory distress syndrome. Due to its intrinsic complexity and relatively low annual volume, simulation is essential for efficient and appropriate ECMO management. COVID-19 has limited the opportunities for high-fidelity in-person simulation training when many hospitals are looking to expand their ECMO services to battle the ongoing pandemic. To meet this demand, the National Cardiovascular Center Harapan Kita, Jakarta, Indonesia, conducted a 3-day ECMO course entailing online didactic lectures (adult and paediatric stream), water drills and telesimulation. PURPOSE: The purpose of the study is to report the evaluation result of this novel model of education during COVID-19 outbreak. DATA COLLECTION: Participants were given an ECMO knowledge pre-course and post-course test and a telesimulation evaluation survey at the conclusion and these data were collected. RESULTS: The course was attended by 104 physicians, critical care nurses and perfusionists. Pre-course and post-course assessments showed a significant improvement in ECMO knowledge (60.0% vs 73.3%, respectively). Overall, the participants rated the telesimulation positively, and most found it acceptable to in-person simulation training considering the pandemic restrictions. CONCLUSION: Despite the complexities of ECMO, our recent experience demonstrates ECMO education and simulation delivered online is feasible, welcomed and supportive of a change in ECMO training course format. As we incorporate more innovative digital technologies, telesimulation may further enhance the quality of future ECMO training.

BACKGROUND: The role of neuromuscular blocking agents (NMBAs) in coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS) is not fully elucidated. Therefore, we aimed to investigate in COVID-19 patients with moderate-to-severe ARDS the impact of early use of NMBAs on 90-day mortality, through propensity score (PS) matching analysis. METHODS: We analyzed a convenience sample of patients with COVID-19 and moderate-to-severe ARDS, admitted to 244 intensive care units within the COVID-19 Critical Care Consortium, from February 1, 2020, through October 31, 2021. Patients undergoing at least 2 days and up to 3 consecutive days of NMBAs (NMBA treatment), within 48 h from commencement of IMV were compared with subjects who did not receive NMBAs or only upon commencement of IMV (control). The primary objective in the PS-matched cohort was comparison between groups in 90-day in-hospital mortality, assessed through Cox proportional hazard modeling. Secondary objectives were comparisons in the numbers of ventilator-free days (VFD) between day 1 and day 28 and between day 1 and 90 through competing risk regression. RESULTS: Data from 1953 patients were included. After propensity score matching, 210 cases from each group were well matched. In the PS-matched cohort, mean (± SD) age was 60.3 ± 13.2 years and 296 (70.5%) were male and the most common comorbidities were hypertension (56.9%), obesity (41.1%), and diabetes (30.0%). The unadjusted hazard ratio (HR) for death at 90 days in the NMBA treatment vs control group was 1.12 (95% CI 0.79, 1.59, p = 0.534). After adjustment for smoking habit and critical therapeutic covariates, the HR was 1.07 (95% CI 0.72, 1.61, p = 0.729). At 28 days, VFD were 16 (IQR 0-25) and 25 (IQR 7-26) in the NMBA treatment and control groups, respectively (sub-hazard ratio 0.82, 95% CI 0.67, 1.00, p = 0.055). At 90 days, VFD were 77 (IQR 0-87) and 87 (IQR 0-88) (sub-hazard ratio 0.86 (95% CI 0.69, 1.07; p = 0.177). CONCLUSIONS: In patients with COVID-19 and moderate-to-severe ARDS, short course of NMBA treatment, applied early, did not significantly improve 90-day mortality and VFD. In the absence of definitive data from clinical trials, NMBAs should be indicated cautiously in this setting.

PURPOSE: Percutaneous cannulation is increasingly used for veno-arterial extracorporeal membrane oxygenation (VA-ECMO). However, there is limited evidence about the benefit of this approach compared with conventional surgical cannulation. By using a large international database, this study was designed to compare in-hospital outcomes in cardiac shock patients who received femoro-femoral VA-ECMO with percutaneous versus surgical cannulation. METHODS: Adults with refractory cardiogenic shock treated with percutaneous (percutaneous group) or surgical (surgical group) femoro-femoral VA-ECMO between January 2008 and December 2019 were extracted from the international Extracorporeal Life Support Organization registry. The primary outcome was in-hospital mortality. Multivariable logistic regression analyses were performed to assess the association between percutaneous cannulation and in-hospital outcomes. RESULTS: Among 12,592 patients meeting study inclusion, 9,249 (73%) underwent percutaneous cannulation. The proportion of patients undergoing percutaneous cannulation increased from 32% to 84% over the study period (p < 0.01 for trend). In-hospital mortality (53% vs 58%; p < 0.01), cannulation site bleeding (19% vs 22%; p < 0.01), and systemic infection (8% vs 15%; p < 0.01) occurred less frequently in the percutaneous group compared to the surgical group. In adjusted analyses, percutaneous cannulation was independently associated with lower rates of in-hospital mortality (odds ratio [OR] 0.76; 95% CI 0.70-0.84; p < 0.01), cannulation site bleeding (OR 0.70; 95% CI 0.60-0.80; p < 0.01) and systemic infection (OR, 0.63; 95% CI 0.54-0.74; p < 0.01). Severe limb ischemia was more frequently observed in the percutaneous group (5% vs 3%; p < 0.01). However, this association was not significant in adjusted analysis (OR 1.28; 95% CI 0.93-1.62; p = 0.15). CONCLUSIONS: Compared with surgical cannulation, percutaneous cannulation was independently associated with lower in-hospital mortality and fewer complications.

Factors associated with mortality in coronavirus disease 2019 patients on invasive mechanical ventilation are still not fully elucidated. OBJECTIVES: To identify patient-level parameters, readily available at the bedside, associated with the risk of in-hospital mortality within 28 days from commencement of invasive mechanical ventilation or coronavirus disease 2019. DESIGN SETTING AND PARTICIPANTS: Prospective observational cohort study by the global Coronavirus Disease 2019 Critical Care Consortium. Patients with laboratory-confirmed coronavirus disease 2019 requiring invasive mechanical ventilation from February 2, 2020, to May 15, 2021. MAIN OUTCOMES AND MEASURES: Patient characteristics and clinical data were assessed upon ICU admission, the commencement of invasive mechanical ventilation and for 28 days thereafter. We primarily aimed to identify time-independent and time-dependent risk factors for 28-day invasive mechanical ventilation mortality. RESULTS: One-thousand five-hundred eighty-seven patients were included in the survival analysis; 588 patients died in hospital within 28 days of commencing invasive mechanical ventilation (37%). Cox-regression analysis identified associations between the hazard of 28-day invasive mechanical ventilation mortality with age (hazard ratio, 1.26 per 10-yr increase in age; 95% CI, 1.16-1.37; p < 0.001), positive end-expiratory pressure upon commencement of invasive mechanical ventilation (hazard ratio, 0.81 per 5 cm H2O increase; 95% CI, 0.67-0.97; p = 0.02). Time-dependent parameters associated with 28-day invasive mechanical ventilation mortality were serum creatinine (hazard ratio, 1.28 per doubling; 95% CI, 1.15-1.41; p < 0.001), lactate (hazard ratio, 1.22 per doubling; 95% CI, 1.11-1.34; p < 0.001), Paco2 (hazard ratio, 1.63 per doubling; 95% CI, 1.19-2.25; p < 0.001), pH (hazard ratio, 0.89 per 0.1 increase; 95% CI, 0.8-14; p = 0.041), Pao2/Fio2 (hazard ratio, 0.58 per doubling; 95% CI, 0.52-0.66; p < 0.001), and mean arterial pressure (hazard ratio, 0.92 per 10 mm Hg increase; 95% CI, 0.88-0.97; p = 0.003). CONCLUSIONS AND RELEVANCE: This international study suggests that in patients with coronavirus disease 2019 on invasive mechanical ventilation, older age and clinically relevant variables monitored at baseline or sequentially during the course of invasive mechanical ventilation are associated with 28-day invasive mechanical ventilation mortality hazard. Further investigation is warranted to validate any causative roles these parameters might play in influencing clinical outcomes.
ABSTRACT
BACKGROUND: Heterogeneous respiratory system static compliance (CRS) values and levels of hypoxemia in patients with novel coronavirus disease (COVID-19) requiring mechanical ventilation have been reported in previous small-case series or studies conducted at a national level. METHODS: We designed a retrospective observational cohort study with rapid data gathering from the international COVID-19 Critical Care Consortium study to comprehensively describe CRS-calculated as: tidal volume/[airway plateau pressure-positive end-expiratory pressure (PEEP)]-and its association with ventilatory management and outcomes of COVID-19 patients on mechanical ventilation (MV), admitted to intensive care units (ICU) worldwide. RESULTS: We studied 745 patients from 22 countries, who required admission to the ICU and MV from January 14 to December 31, 2020, and presented at least one value of CRS within the first seven days of MV. Median (IQR) age was 62 (52-71), patients were predominantly males (68%) and from Europe/North and South America (88%). CRS, within 48 h from endotracheal intubation, was available in 649 patients and was neither associated with the duration from onset of symptoms to commencement of MV (p = 0.417) nor with PaO2/FiO2 (p = 0.100). Females presented lower CRS than males (95% CI of CRS difference between females-males: - 11.8 to - 7.4 mL/cmH2O p < 0.001), and although females presented higher body mass index (BMI), association of BMI with CRS was marginal (p = 0.139). Ventilatory management varied across CRS range, resulting in a significant association between CRS and driving pressure (estimated decrease - 0.31 cmH2O/L per mL/cmH20 of CRS, 95% CI - 0.48 to - 0.14, p < 0.001). Overall, 28-day ICU mortality, accounting for the competing risk of being discharged within the period, was 35.6% (SE 1.7). Cox proportional hazard analysis demonstrated that CRS (+ 10 mL/cm H2O) was only associated with being discharge from the ICU within 28 days (HR 1.14, 95% CI 1.02-1.28, p = 0.018). CONCLUSIONS: This multicentre report provides a comprehensive account of CRS in COVID-19 patients on MV. CRS measured within 48 h from commencement of MV has marginal predictive value for 28-day mortality, but was associated with being discharged from ICU within the same period.

DISCLAIMER: This is an updated guideline from the Extracorporeal Life Support Organization (ELSO) for the role of extracorporeal membrane oxygenation (ECMO) for patients with severe cardiopulmonary failure due to coronavirus disease 2019 (COVID-19). The great majority of COVID-19 patients (>90%) requiring ECMO have been supported using venovenous (V-V) ECMO for acute respiratory distress syndrome (ARDS). While COVID-19 ECMO run duration may be longer than in non-COVID-19 ECMO patients, published mortality appears to be similar between the two groups. However, data collection is ongoing, and there is a signal that overall mortality may be increasing. Conventional selection criteria for COVID-19-related ECMO should be used; however, when resources become more constrained during a pandemic, more stringent contraindications should be implemented. Formation of regional ECMO referral networks may facilitate communication, resource sharing, expedited patient referral, and mobile ECMO retrieval. There are no data to suggest deviation from conventional ECMO device or patient management when applying ECMO for COVID-19 patients. Rarely, children may require ECMO support for COVID-19-related ARDS, myocarditis, or multisystem inflammatory syndrome in children (MIS-C); conventional selection criteria and management practices should be the standard. We strongly encourage participation in data submission to investigate the optimal use of ECMO for COVID-19.

AIM: We chose to evaluate the survival of extracorporeal membrane oxygenation among patients with human immunodeficiency virus in a multicenter registry. METHODS: Retrospective case review of the Extracorporeal Life Support Organization Registry respiratory failure of all patients with human immunodeficiency virus supported with extracorporeal membrane oxygenation. RESULTS: A total of 126 patients were included. Survival to discharge was 36%. Eight infants were supported with extracorporeal membrane oxygenation and three (37.5%) survived to discharge. Respiratory extracorporeal membrane oxygenation was the primary indication (78%) with a 39% survival, while cardiac and extracorporeal cardiopulmonary resuscitation indications accounted for 16% and 6% of patients with survivals of 30% and 12.5%, respectively. These differences did not reach significance. There were no significant differences between survivors and non-survivors in demographic data, but non-survivors had significantly more non-human immunodeficiency virus pre-extracorporeal membrane oxygenation infections than survivors. There were no differences in other pre-extracorporeal membrane oxygenation supportive therapies, mechanical ventilator settings, or arterial blood gas results between survivors and non-survivors. The median duration of mechanical ventilation prior to cannulation was 52 (interquartile range: 13-140) hours, while the median duration of the extracorporeal membrane oxygenation exposure was 237 (interquartile range: 125-622) hours. Ventilator settings were significantly lower after 24 hours compared to pre-extracorporeal membrane oxygenation settings. Complications during extracorporeal membrane oxygenation exposure including receipt of renal replacement therapy, inotropic infusions, and cardiopulmonary resuscitation were more common among non-survivors compared to survivors. Central nervous system complications were rare. CONCLUSION: Survival among patients with human immunodeficiency virus infection who receive extracorporeal membrane oxygenation was less than 40%. Infections before extracorporeal membrane oxygenation cannulation occurred more often in non-survivors. The receipt of renal replacement therapy, inotropic infusions, or cardiopulmonary resuscitation during extracorporeal membrane oxygenation was associated with worse outcome.

WHO interim guidelines recommend offering extracorporeal membrane oxygenation (ECMO) to eligible patients with acute respiratory distress syndrome (ARDS) related to coronavirus disease 2019 (COVID-19). The number of patients with COVID-19 infection who might develop severe ARDS that is refractory to maximal medical management and require this level of support is currently unknown. Available evidence from similar patient populations suggests that carefully selected patients with severe ARDS who do not benefit from conventional treatment might be successfully supported with venovenous ECMO. The need for ECMO is relatively low and its use is mostly restricted to specialised centres globally. Providing complex therapies such as ECMO during outbreaks of emerging infectious diseases has unique challenges. Careful planning, judicious resource allocation, and training of personnel to provide complex therapeutic interventions while adhering to strict infection control measures are all crucial components of an ECMO action plan. ECMO can be initiated in specialist centres, or patients can receive ECMO during transportation from a centre that is not specialised for this procedure to an expert ECMO centre. Ensuring that systems enable safe and coordinated movement of critically ill patients, staff, and equipment is important to improve ECMO access. ECMO preparedness for the COVID-19 pandemic is important in view of the high transmission rate of the virus and respiratory-related mortality.

OBJECTIVES: The purpose of this position paper is two-fold: first, to describe the state of extracorporeal membrane oxygenation education worldwide, noting current limitations and challenges; and second, to put forth an educational agenda regarding opportunities for an international collaborative approach toward standardization. DESIGN: Relevant medical literature was reviewed through literature search, and materials from national organizations were accessed through the Internet. Taskforce members generated a consensus statement using an iterative consensus process through teleconferences and electronic communication. SETTING: In 2018, the Extracorporeal Life Support Organization convened the ECMOed Taskforce at two structured, face-to-face meetings of 40 healthcare practitioners and educators with expertise in caring for the extracorporeal membrane oxygenation patient and in extracorporeal membrane oxygenation education. PATIENTS: None. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The ECMOed Taskforce identified seven educational domains that would benefit from international collaborative efforts. Of primary importance, the Taskforce outlined actionable items regarding 1) the creation of a standardized extracorporeal membrane oxygenation curriculum; 2) defining criteria for an extracorporeal membrane oxygenation course as a vehicle for delivering the curriculum; 3) outlining a mechanism for evaluating the quality of educational offerings; 4) utilizing validated assessment tools in the development of extracorporeal membrane oxygenation practitioner certification; and 5) promoting high-quality educational research to guide ongoing educational and competency assessment development. CONCLUSIONS: Significant variability and limitations in global extracorporeal membrane oxygenation education exist. In this position paper, we outline a road map for standardizing international extracorporeal membrane oxygenation education and practitioner certification. Ongoing high-quality educational research is needed to evaluate the impact of these initiatives.

BACKGROUND: Extracorporeal membrane oxygenation relies heavily on didactic teaching, emphasizing on essential cognitive skills, but overlooking core behavioral skills such as leadership and communication. Therefore, simulation-based training has been adopted to instill clinical knowledge through immersive experiences. Despite simulation-based training's effectiveness, training opportunities are lessened due to high costs. This is where screen-based simulators come into the scene as affordable and realistic alternatives. AIM: This article evaluates the educational efficacy of ECMOjo, an open-source screen-based extracorporeal membrane oxygenation simulator that aims to replace extracorporeal membrane oxygenation didactic instruction in an interactive and cost-effective manner. METHOD: A prospective cohort skills acquisition study was carried out. A total of 44 participants were pre-assessed, divided into two groups, where the first group received traditional didactic teaching, and the second used ECMOjo. Participants were then evaluated through a wet lab assessment and two questionnaires. RESULTS: The obtained results indicate that the two assessed groups show no statistically significant differences in knowledge and efficacy. Hence, ECMOjo is considered an alternative to didactic teaching as per the learning outcomes. CONCLUSION: The present findings show no significant dissimilarities between ECMOjo and didactic classroom-based teaching. Both methods are very comparable in terms of the learner's reported self-efficacy and complementary to mannequin-based simulations.

Extracorporeal membrane oxygenation (ECMO) is used in patients with acute respiratory failure that is not responsive to conventional management. The practice of awake ECMO has become an area of interest but with limited data and experience. Most reported experience comes from adult and pediatric populations. Traditional management of these patients still includes mechanical ventilator support and often requires the use of sedatives for provision of safe care. We present a series of eight neonates who were electively extubated while on ECMO, with expanded discussion of two representative cases. We discuss the rationale for extubation and outcomes. The greatest benefit of this management was seen in patients with significant air leak, and in no reported case did we experience any adverse effects or complications as a direct result of extubation while on ECMO. In conclusion, in our experience, awake neonatal ECMO appears safe and effective and may offer significant advantages over traditional management in certain clinical scenarios. Prospective comparison trials are warranted to further investigate the clinical benefits and risks of awake neonatal ECMO.

BACKGROUND: Prediction scoring systems for coronary artery bypass grafting (CABG) patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO) have not yet been reported. This study was designed to develop a predictive score for in-hospital mortality for cardiogenic shock patients who received VA-ECMO after isolated CABG. METHODS: Retrospective cohort study of consecutive CABG patients supported with VA-ECMO (n = 166) at the Beijing Anzhen Hospital between February 2004 and March 2017. RESULTS: One hundred and six patients (64%) could be weaned from VA-ECMO, and 74 patients (45%) survived to hospital discharge. On the basis of multivariable logistic regression analyses, the pRedicting mortality in patients undergoing veno-arterial Extracorporeal MEMBrane oxygenation after coronary artEry bypass gRafting (REMEMBER) score was created with six pre-ECMO parameters: older age, left main coronary artery disease, inotropic score > 75, CK-MB > 130 IU/L, serum creatinine > 150 umol/L, and platelet count < 100 × 109/L. Four risk classes, namely class I (REMEMBER score 0-13), class II (14-19), class III (20-25), and class IV (> 25) with their corresponding mortality (13%, 55%, 70%, and 94%, respectively), were identified. The area under the receiver operating characteristic curve 0.85(95% CI 0.79-0.91) for the REMEMBER score was better than those for the SOFA, SAVE, EuroSCORE, and ENCOURAGE scores in this population. CONCLUSIONS: The REMEMBER score might help clinicians at bedside to predict in-hospital mortality for patients receiving VA-ECMO after isolated CABG for refractory cardiogenic shock. Prospective studies are needed to externally validate this scoring system.

Extracorporeal membrane oxygenation (ECMO) is used for cardiopulmonary dysfunction. Hepatopulmonary syndrome (HPS) occurs in the setting of liver failure and may cause hypoxemia. Previous reports have described the use of ECMO for HPS after liver transplant. Our patient is a 19-month-old female with biliary atresia, an interrupted inferior vena cava, and HPS on 8 liters per minute of high-flow oxygen. Following liver transplantation, her postoperative course was complicated by severe hypoxemia requiring ECMO. Due to her interrupted inferior vena cava, our standard bi-caval cannula could not be used. Hence, a 16-French double lumen venovenous right internal jugular to right atrial cannula was used to provide extracorporeal life support. She was decannulated after 17 days, remained intubated for 2 days, and weaned to room air over the next 3 weeks. This is the third pediatric liver transplant patient supported with ECMO identified in the literature, and the youngest and smallest of those reported. This approach to cannulation is unique because of the use of a double lumen venovenous cannula for HPS in a child, selected due to complex anatomy. Posttransplant ECMO may provide pediatric patients with HPS and posttransplant hypoxemia a period of support for their pulmonary remodeling and recovery from HPS.
