Background: Extracorporeal cardiopulmonary resuscitation (ECPR) for refractory cardiac arrest has improved mortality in post-cardiac surgery patients; however, loss of neurologic function remains one of the main and devastating complications. We reviewed our experience with ECPR and investigated the effect of cannulation strategy on neurologic outcome in adult patients who experienced cardiac arrest following cardiac surgery that was managed with ECPR. Methods: Patients were categorized by central versus percutaneous peripheral VA-extracorporeal membrane oxygenation (ECMO) cannulation strategy. We reviewed patient records and evaluated in-hospital mortality, cause of death, and neurologic status 72 hours after cannulation. Results: From January 2010 to September 2019, 44 patients underwent post-cardiac surgery ECPR for cardiac arrest. Twenty-six patients received central cannulation; 18 patients received peripheral cannulation. Mean post-operative day of the cardiac arrest was 3 and 9 days (p = 0.006), and mean time between initiation of CPR and ECMO was 40 ± 24 and 28 ± 22 minutes for central and peripheral cannulation, respectively. After 72 hours of VA-ECMO support, 30% of centrally cannulated patients versus 72% of peripherally cannulated patients attained cerebral performance status 1–2 (p = 0.01). Anoxic brain injury was the cause of death in 26.9% of centrally cannulated and 11.1% of peripherally cannulated patients. Survival to discharge was 31% and 39% for central and peripheral cannulation, respectively. Conclusions: Peripheral VA-ECMO allows for continuous CPR and systemic perfusion while obtaining vascular access. Compared to central cannulation, a peripheral cannulation strategy is associated with improved neurologic outcomes and decreased likelihood of anoxic brain death.

Abstract Purpose: To assess the outcomes and risk factors for adult patients with acute fulminant myocarditis supported with venoarterial extracorporeal membrane oxygenation (VA ECMO) in China mainland. Methods: Data were extracted from Chinese Society of ExtraCorporeal Life Support (CSECLS) Registry database. Data from adult patients who were diagnosed with acute myocarditis and needed VA ECMO in the database were retrospectively analyzed. The primary outcome was 90-day mortality after ECMO initiation in patients with acute fulminant myocarditis supported with VA ECMO. Cox proportional hazard regression model was used to examine the risk factors associated with 90-day mortality. Results: Among 221 patients enrolled, 186 (84.2%) patients weaned from ECMO and 159 (71.9%) patients survived to 90 days. The median age was 38 years (IQR 29-49) and males (n=115) accounted for 52.0% of the patients. The median ECMO duration was 134 hours (IQR 96-177hrs). The main adverse events during ECMO course was bleeding (16.3%), followed by infection (15.4%). In the multivariate Cox model, cardiac arrest prior to ECMO initiation (adjusted HR 2.529; 95%CI: 1.341-4.767, p =0.004), lower pH value (adjusted HR 0.016; 95%CI: 0.010-0.059, p <0.001) and higher lactate concentration at 24 hours after ECMO initiation (adjusted HR 1.146; 95%CI: 1.075-1.221, p <0.001) was associated with 90day mortality. Conclusions: In our study, 71.9% patients with acute fulminant myocarditis supported with VA ECMO survived to 90 days. Cardiac arrest prior to ECMO, lower pH and higher lactate concentration at 24 hours after ECMO initiation were correlated with 90-day mortality closely.ClinicalTrials.gov registration number: NCT04158479, Registered 8 November 2019, https://clinicaltrials.gov/ct2/show/NCT04158479?term=hou+xiaotong&draw=2&rank=2.

AbstractNon-hemorrhagic brain infarction (BI) is a recognized complication in adults treated with extracorporeal membrane oxygenation (ECMO) and associated with increased mortality. However, predictors of BI in these patients are poorly understood. The aim of this study was to identify predictors of BI in ECMO-treated adult patients. We conducted an observational cohort study of all adult patients treated with venovenous or venoarterial (VA) ECMO at our center between 2010 and 2018. The primary endpoint was a computed tomography (CT) verified BI. Logistic regression models were employed to identify BI predictors. In total, 275 patients were included, of whom 41 (15%) developed a BI. Pre-ECMO Simplified Acute Physiology Score III, pre-ECMO cardiac arrest, VA ECMO and conversion between ECMO modes were identified as predictors of BI. In the multivariable analysis, VA ECMO demonstrated independent risk association. VA ECMO also remained the independent BI predictor in a sub-group analysis excluding patients who did not undergo a head CT scan during ECMO treatment. The incidence of BI in adult ECMO patients may be higher than previously believed and is independently associated with VA ECMO mode. Larger prospective trials are warranted to validate these findings and ascertain their clinical significance.

Background: The suitability of model for end-stage liver disease excluding international normalized ratio (MELD-XI) score to predict the incidence of acute kidney injury (AKI) and in-hospital mortality in adult patients with postcardiotomy cardiogenic shock (PCS) requiring venoarterial extracorporeal membrane oxygenation (VA ECMO) remains uncertain. This study was performed to explore whether the MELD-XI score has the association with the incidence of AKI and in-hospital mortality in these patients. Methods: Adult patients with PCS requiring VA ECMO from January 2012 to December 2017 were enrolled and first classified into AKI group ( n = 151) versus no-AKI group ( n = 132), then classified into survival group ( n = 143) versus no-survival group ( n = 140). Multivariate logistic regressions were performed to identify factors independently associated with AKI and mortality. Baseline data were defined as the first measurement available. Results: Of 283 patients, the incidence of AKI was 53.36%. The in-hospital mortality rates were 63.58% and 33.33% in patients with and without AKI (p < 0.0001). Baseline MELD-XI score, baseline serum total bilirubin (T-Bil), baseline blood urea nitrogen (BUN), baseline left ventricular ejection fraction (LVEF), sequential organ failure assessment (SOFA) score, and lactate level at ECMO initiation were shown to be associated with the AKI. Vasoactive-inotropic score (VIS) and SOFA score at ECMO initiation as well as renal failure requiring renal replacement therapy (RRT) were shown to be associated with in-hospital mortality. Conclusions: The baseline MELD-XI score, baseline BUN, baseline T-Bil, baseline LVEF, SOFA score and lactate at the initiation of ECMO were associated with AKI. AKI, SOFA score, and VIS at the initiation of ECMO were associated with in-hospital mortality, whereas MELD-XI score was not found to be associated with in-hospital mortality. A specific MELD-XI score as a threshold, as well as its sensitivity and specificity, needs to be confirmed in further studies.

Background: There is no heart transplantation centre on the French overseas territory of Reunion Island (distance of 10,000 km). The aim of this study was to describe the characteristics of cardiogenic shock adult patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO) who were transferred from Reunion Island to mainland France for emergency heart transplantation. Methods: This retrospective observational study was conducted between 2005 and 2015. The characteristics and outcome of cardiogenic shock patients on VA-ECMO were compared with those of cardiogenic shock patients not on VA-ECMO. Results: Thirty-three cardiogenic shock adult patients were transferred from Reunion Island to Paris for emergency heart transplantation. Among them, 19 (57.6%) needed mechanical circulatory support in the form of VA-ECMO. Median age was 51 (33–57) years and 46% of the patients had ischaemic heart disease. Patients on VA-ECMO presented higher Sequential Organ Failure Assessment score ( p = 0.03). No death occurred during the medical transfer by long flight, while severe complications occurred in 10 patients (30.3%). Incidence of thromboembolic events, severe infectious complications and major haemorrhages was higher in the group of patients on VA-ECMO than in the group of patients not on VA-ECMO ( p <0.01). Seven patients from the VA-ECMO group (36.8%) and six patients from the non-VA-ECMO group (42.9%, p=0.7) underwent heart transplantation after a median delay of 10 (4–29) days on the emergency waiting list. After heart transplantation, one-year survival rates were 85.7% for patients on VA-ECMO and 83.3% for patients not on VA-ECMO ( p=0.91). Conclusions: This study suggests the feasibility of very long-distance medical evacuation of cardiogenic shock patients on VA-ECMO for emergency heart transplantation, with acceptable long-term results.

Background: There is a lack of consensus on the timing of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) liberation. VA-ECMO weaning usually consists of serial decrements until an idling flow is achieved, supported by echocardiographic and haemodynamic assessments. Even with minimal idling flow, right ventricular (RV) preload is reduced and, hence, right heart function is not fully tested under adequate loading conditions. Following the use of a novel technique called Pump Controlled Retrograde Trial Off (PCRTO) in neonate VA-ECMO weaning, we report the use of this technique in seven adult patients on VA-ECMO. Methods: We retrospectively reviewed all adult VA-ECMO patients treated at a tertiary teaching hospital in Hong Kong since 2010. Clinical data, including diagnosis, echocardiography findings, ECMO configuration, PCRTO settings, survival after veno-arterial ECMO (SAVE) score and outcomes, were collected. Mortality and death due to cardiac failure was compared between PCRTO and conventional weaning. Results: Seven patients underwent PCRTO, with a mean SAVE score of -4.4 ± 5.9. All seven patients were successfully decannulated without haemodynamic deterioration. In all cases, no clots or fibrin deposits were found in the circuit after the trial. There was no difference in mean SAVE scores among the seven patients in PCRTO and the 23 patients in the conventional group (-3.6, 95% CI -8.8 to 1.5). The number of deaths due to cardiac failure in the PCRTO group and the conventional group were 0 and 3, respectively (0% vs. 13%, p=0.99). Mortality after decannulation for PCRTO was 42.9% vs. conventional weaning 34.8% (p=0.99). Conclusion: Our study suggests that PCRTO is a simple, safe and reversible alternative weaning method. It may have a particular role in the assessment of patients who have marginal recovery and right heart failure. Prospective controlled studies are needed to establish the potential role of PCRTO in the liberation of patients from VA-ECMO support.

Abstract Objective. Upper gastrointestinal bleeding is a common complication in adults treated with veno-arterial Extracorporeal Membrane Oxygenation (VA-ECMO) for refractory cardiogenic shock or cardiac arrest. We aimed to determine risk factors, prevalence and outcomes associated with upper gastrointestinal bleeding (UGIB) in adult patients under VA-ECMO.Design. We conducted a retrospective cohort study (2014-2017) on consecutive VA-ECMO patients.Setting. Medical and Infectious Disease intensive care unit of university hospital Bichat-Claude Bernard in Paris, France.Patients. UGIB was defined as 1) an overt bleeding (hematemesis, melena, hematochezia), or 2) acute anemia associated with a lesion diagnosed on upper gastrointestinal endoscopy. Cause-specific models were used to identify factors associated with UGIB and death, respectively.Measurements and Main Results. 257 patients were included, of whom 48 (19%) were diagnosed with UGIB after a median of 18 [7; 43] days following cannulation; median SAPS II was 59 [43; 76]. 100 (39%) patients were implanted after cardiac surgery. Mortality occurred in 31 (65%) patients with UGIB and 121 (58%) patients without. UGIB patients had longer ICU stays (41 [19; 82] vs. 15 [6; 26]; p<.01), longer ECMO (10.5 [7; 15] vs 6 [3; 10]; p <.01) and mechanical ventilation durations (31 [18; 45] vs. 9 [5; 18]; p <.01) in days, as compared to non-UGIB patients. Ninety-nine upper gastrointestinal endoscopies (UGE) were performed and the most frequent lesions detected were gastro-duodenal ulcers (n=28, 28%), leading to 12/99 therapeutic procedures. Neither antiplatelet therapy prior to ICU admission nor a history of peptic ulcer were associated with UGIB in univariate analysis. By multivariate analysis (table), a BMI (body mass index) > 30 kg/m2 (Cause-specific hazard ratio (CSHR) [95% CI]): 3.06 [1.56; 5.98]), and extracorporeal cardiopulmonary resuscitation (ECPR) (CSHR 2.34 [1.03; 5.35]) were independently associated with an increased risk of UGIB. Conclusions. In adult patients under VA-ECMO, obesity and ECPR were independently associated with UGIB. This study highlights the potential role of obesity and acute ischemia reperfusion injury in the pathophysiology of VA-ECMO-associated UGIB.

AbstractAcute kidney injury (AKI) has been reported as one of the most common complications in patients receiving extracorporeal membrane oxygenation (ECMO), yet the risk of AKI on different types of ECMO remains unclear. This meta-analysis aimed to compare risk of AKI among adult patients requiring different types of ECMO. Two authors independently performed a literature search using PubMed, Web of Science, and Embase, encompassing publications up until Arpril 20, 2020 (inclusive). The number of AKI patients, non-AKI patients, patients required RRT and patients not required RRT receiving different types of ECMO were derived and analyzed by STATA. The results indicated there was no significant difference in risk of AKI (OR, 1.54; 95% CI: 0.75-3.16; P= 0.235) and severe AKI required RRT (OR, 1.0; 95% CI: 0.66-1.5, P= 0.994) in patients receiving different types of ECMO. In Conclusion, no difference in risk of AKI and severe AKI required RRT between patients receiving VA ECMO and VV ECMO. More studies are required to support the findings.

Cardiopulmonary resuscitation (CPR) with closed-chest cardiac massage was developed to maintain circulation and ventilation until life-threatening problems could be corrected or reversed. Studies on the effect of CPR have shown that about 80-95 % cases of resuscitation are fatal or severe neurological consequences and survival to discharge after CPR ranged from 6 to 22 % [2, 4, 8, 11]. Furthermore, the chances of survival decline rapidly if the resuscitation period more than 10 minute. At the same time, we know that successful neurologic outcomes are inversely associated with the time of brain hypoperfusion. Because of the low survival rate after prolonged CPR, more aggressive methods have been suggested to increase success. With the advancement of techniques, extracorporeal mechanical support has been applied in conjunction with CPR, with variable results [5, 12]. To assess the efficacy of resuscitation with extracorporeal membrane oxygenation was modeled the acute hypoxic cardiac arrest in pigs. Results of the study in the two groups demonstrate efficient switching method supporting circulatory support (ECMO) in the minutes of CPR. In the provision of an extended set of measures of cardiopulmonary resuscitation in the modeling of hypoxic cardiac arrest in animals in the group with ECMO received great survival to the end of the experiment, less expressed manifestations of acute heart failure. Intergroup comparison given the prerequisites for the development of protocols with the use of ECMO CPR, which would reduce the number of complications and death in patients undergoing cardiac surgery.
