Abstract
Secondary infections in coronavirus disease 2019 (COVID-19) patients are difficult to distinguish from inflammation associated with COVID-19 and/or extracorporeal membrane oxygenation (ECMO). Therefore, highly specific and sensitive biomarkers are needed to identify patients in whom antimicrobial therapy can be safely withheld. In this prospective monocentric study, 66 COVID-19 patients admitted to the intensive care unit (ICU) for ECMO evaluation were included. A total of 46 (70%) patients with secondary infections were identified by using broad microbiological and virological panels and standardized diagnostic criteria. Various laboratory parameters including C-reactive protein (CRP), interleukin (IL)-6, procalcitonin (PCT), and IL-10 were determined at time of study inclusion. The best test performance for differentiating bacterial/fungal secondary infections and COVID-19 and/or ECMO associated inflammation was achieved by IL-10 (ROC-AUC 0.84) and a multivariant step-wise regression model including CRP, IL-6, PCT, and IL-10 (ROC-AUC 0.93). Data obtained in the present study highlights the use of IL-10 to differentiate secondary bacterial/fungal infections from COVID-19 and/or ECMO associated inflammation in severely ill COVID-19 patients.

Abstract
The novel coronavirus infection SARS-CoV-2, which broke out in China in December 2019, has rapidly spread around the world. On March 11, 2020, the World Health Organization (WHO) assigned this infection pandemic status. Pregnant women and puerperae occupy a special place in the structure of the incidence of COVID-19. For more than a year and a half, the Lapino Clinical Hospital of the Mother and Child Group of Companies has accumulated significant experience in managing patients with COVID-19, including pregnant women and puerperae. This article presents the features of the course of the new coronavirus infection in pregnant women and puerperae during various periods of the pandemic, the experience of managing pregnancy and childbirth in the above group of patients, and methods of treatment.

Veno-Arterial Extracorporeal Membrane Oxygenation (ECMO) Impairs Bradykinin-Induced Relaxation in Neonatal Porcine Coronary Arteries. Biomedicines 2022; 10:biomedicines10092083. [PMID: 36140183 PMCID: PMC9495700 DOI: 10.3390/biomedicines10092083] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 08/18/2022] [Accepted: 08/19/2022] [Indexed: 11/26/2022] Open
Abstract
Extracorporeal membrane oxygenation (ECMO) is a lifesaving support for respiratory and cardiovascular failure. However, ECMO induces a systemic inflammatory response syndrome that can lead to various complications, including endothelial dysfunction in the cerebral circulation. We aimed to investigate whether ECMO-associated endothelial dysfunction also affected coronary circulation. Ten-day-old piglets were randomized to undergo either 8 h of veno-arterial ECMO (n = 5) or no treatment (Control, n = 5). Hearts were harvested and coronary arteries were dissected and mounted as 3 mm rings in organ baths for isometric force measurement. Following precontraction with the thromboxane prostanoid (TP) receptor agonist U46619, concentration−response curves to the endothelium-dependent vasodilator bradykinin (BK) and the nitric oxide (NO) donor (endothelium-independent vasodilator) sodium nitroprusside (SNP) were performed. Relaxation to BK was studied in the absence or presence of the NO synthase inhibitor Nω-nitro-L-arginine methyl ester HCl (L-NAME). U46619-induced contraction and SNP-induced relaxation were similar in control and ECMO coronary arteries. However, BK-induced relaxation was significantly impaired in the ECMO group (30.4 ± 2.2% vs. 59.2 ± 2.1%; p < 0.0001). When L-NAME was present, no differences in BK-mediated relaxation were observed between the control and ECMO groups. Taken together, our data suggest that ECMO exposure impairs endothelium-derived NO-mediated coronary relaxation. However, there is a NO-independent component in BK-induced relaxation that remains unaffected by ECMO. In addition, the smooth muscle cell response to exogenous NO is not altered by ECMO exposure.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) is a novel coronavirus-caused infectious acute respiratory disease that can progress to severe acute respiratory distress syndrome (ARDS). For severe cases, extracorporeal membrane oxygenation (ECMO) is an excellent treatment option. ECMO had a number of side effects, including bleeding. Intracerebral hemorrhage can occur in COVID patients due to a variety of mechanisms, including covid's effect on ACE-2 receptors and subsequent hypertension, coagulopathy, DIC, or medication, such as anticoagulant use. CASE We present a case of a 53-year-old male COVID-19 patient who developed multiple, massive, severe intracerebral hemorrhages (ICH) despite a normal coagulation profile after ECMO treatment. CONCLUSION COVID-19 can progress to severe acute respiratory distress syndrome (ARDS), necessitating the use of extracorporeal membrane oxygenation (ECMO). Although ICH is not a common complication in patients with COVID-19 disease, it is unknown why this patient had a lower threshold of ICH despite having a normal coagulation profile.

Front Cardiovasc Med 2022; 9:917610.

Abstract
Objective Studies on extracorporeal membrane oxygenation (ECMO) with and without an intra-aortic balloon pump (IABP) for cardiogenic shock (CS) have been published, but there have been no meta-analyses that compare the efficacy of these two cardiac support methods. This meta-analysis evaluated the outcomes of these two different treatment measures. Methods The PubMed, Embase, Cochrane Library, Web of Science, and Clinical Trials databases were searched until March 2022. Studies that were related to ECMO with or without IABP in patients with CS were screened. Quality assessments were evaluated with the methodological index for nonrandomized studies (MINORS). The primary outcome was in-hospital survival, while the secondary outcomes included duration of ECMO, duration of ICU stay, infection/sepsis, and bleeding. Revman 5.3 and STATA software were used for this meta-analysis. Results In total, nine manuscripts with 2,573 patients were included in the systematic review. CS patients who received ECMO in combination with IABP had significantly improved in-hospital survival compared with ECMO alone (OR = 1.58, 95% CI = 1.26–1.98, P < 0.0001). However, there were no significant differences in the duration of ECMO (MD = 0.36, 95% CI = −0.12–0.84, P = 0.14), duration of ICU stay (MD = −1.95, 95% CI = −4.05–0.15, P = 0.07), incidence of infection/sepsis (OR = 1.0, 95% CI = 0.58–1.72, P = 1.0), or bleeding (OR = 1.28, 95% CI = 0.48–3.45, P = 0.62) between the two groups of patients with CS. Conclusion ECMO combined with IABP can improve in-hospital survival more effectively than ECMO alone in patients with CS.

Annual hospital procedural volume and outcome in extracorporeal membrane oxygenation for respiratory failure. Artif Organs 2022; 46:2469-2477. [PMID: 35841283 DOI: 10.1111/aor.14364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 07/01/2022] [Accepted: 07/06/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND The hospital mortality of patients suffering from pulmonary failure requiring venovenous extracorporeal membrane oxygenation (V-V ECMO) or extracorporeal carbon dioxide removal (ECCO2 R) is high. It is unclear whether outcome correlates with a hospital's annual procedural volume. METHODS Data on all V-V ECMO and ECCO2 R cases treated from 2007 to 2019 was retrieved from the German Institute for Medical Documentation and Information. Comorbidities and outcomes were assessed by DRG, OPS, and ICD codes. The study population was divided into 5 groups depending on annual hospital V-V ECMO and ECCO2 R volumes (<10 cases; 10-19 cases; 20-29 cases; 30-49 cases; ≥50 cases). Primary outcome was hospital mortality. RESULTS A total of 25,096 V-V ECMO and 3,607 ECCO2 R cases were analyzed. V-V ECMO hospitals increased from 89 in 2007 to 214 in 2019. Hospitals handling <10 cases annually increased especially (64 in 2007 to 149 in 2019). V-V ECMO cases rose from 807 in 2007 to 2,597 in 2019. Over 50% were treated in hospitals handling ≥30 cases annually. Hospital mortality was independent of the annual hospital procedural volume (55.3%; 61.3%; 59.8%; 60.2%; 56.3%, respectively, p=0.287). We detected no differences when comparing hospitals handling <30 cases to those with ≥30 annually (p=0.659). The numbers of ECCO2 R hospitals and cases has dropped since 2011 (287 in 2007 to 48 in 2019). No correlation between annual hospital procedural volume and hospital mortality was identified (p=0.914). CONCLUSION The number of hospitals treating patients requiring V-V ECMO and V-V ECMO cases rose from 2007 to 2019, while ECCO2 R hospitals and their case numbers decreased. We detected no correlation between annual hospital V-V ECMO or ECCO2 R volume and hospital mortality.

Abstract
BACKGROUND Training is an essential aspect of providing high-quality treatment and ensuring patient safety in any medical practice. Because extracorporeal membrane oxygenation (ECMO) is a complicated operation with various elements, variables, and irregular situations, doctors must be experienced and knowledgeable about all conventional protocols and emergency procedures. The conventional simulation approach has a number of limitations. The approach is intrinsically costly since it relies on disposable medical equipment (i.e., oxygenators, heat exchangers, pumps) that must be replaced regularly due to the damage caused by the liquid used to simu- late blood. The oxygenator, which oxygenates the blood through a tailored membrane in ECMO, acts as a replacement for the patient's natural lung. For the context of simulation-based training (SBT) oxygenators are often expensive and cannot be recy- cled owing to contamination issues. METHODS Consequently, it is advised that the training process include a simu- lated version of oxygenators to optimize re-usability and decrease training expenses. Toward this goal, this article demonstrates a mock oxygenator for ECMO SBT, designed to precisely replicate the real machine structure and operation. RESULTS The initial model was reproduced using 3D modeling and printing. Addi- tionally, the mock oxygenator could mimic frequent events such as pump noise and clotting. Furthermore, the oxygenator is integrated with the modular ECMO simula- tor using cloud-based communication technology that goes in hand with the internet of things (IoT) technology to provide remote control via an instructor tablet applica- tion (App). CONCLUSIONS The final 3D modeled oxygenator body was tested and integrated with the other simulation modules at Hamad Medical Corporation (HMC) with several participants to evaluate the effectiveness of the training session.

Abstract
Background Polymyxins antibiotics have become the first-line clinical drugs in the treatment of refractory gram-negative bacterial infections. Currently, there is a lack of clinical studies on the effect of extracorporeal membrane oxygenation (ECMO) combined with continuous renal replacement therapy (CRRT) on polymyxin concentrations. The purpose of this report was to investigate the changes in the plasma concentrations of Colistin sulfate during ECMO and CRRT and to provide drug administration programs for critically ill patients receiving ECMO and CRRT. Case Description In this case report, a patient with septic shock caused by severe acute pancreatitis, with abdominal pain and dyspnea as the main manifestations, was treated with ECMO combined with CRRT for life support and multiple anti-infective drugs. However, the symptoms of infection had not got improved, the inflammatory indicators remain high and the body temperature fluctuates repeatedly 36.7–38.5 ℃, was considered as carbapenem-resistant organisms (CROs) infection, and was empirically given Colistin sulfate for anti-infection treatment. Finally, the patient’s condition improved and ECMO and CRRT were gradually withdrawn. At the same time, the plasma concentrations of Colistin sulfate before and after ECMO combined with CRRT, was monitored to determine the changes in the plasma concentrations of Colistin sulfate during ECMO and CRRT. Trough and peak concentrations on the 4th day of venovenous ECMO (VV-ECMO) combined with CRRT were 0.36 and 0.98 mg/L, respectively. After withdrawal of ECMO and CRRT, the concentrations were, respectively, 0.27 and 0.34 mg/L for trough concentrations, and 0.82 and 0.98 mg/L for peak concentrations. The data showed that there were no significant differences in the trough and peak concentrations of Colistin sulfate before and after ECMO and CRRT. No adverse effects occurred during follow-up. Conclusions There were no significant differences in the trough and peak concentrations of Colistin sulfate before and after ECMO and CRRT. Therefore, no dose modification is required for Colistin sulfate in patients receiving ECMO with CRRT.

Abstract
Postmortem normothermic regional perfusion (NRP) is a rising preservation strategy in controlled donation after circulatory determination of death (cDCD). Herein, we present results for cDCD liver transplants performed in Spain 2012-2019, with outcomes evaluated through December 31, 2020. Results were analyzed retrospectively and according to recovery technique (abdominal NRP [A-NRP] or standard rapid recovery [SRR]). During the study period, 545 cDCD liver transplants were performed with A-NRP and 258 with SRR. Median donor age was 59 years (interquartile range 49-67 years). Adjusted risk estimates were improved with A-NRP for overall biliary complications (OR 0.300, 95% CI 0.197-0.459, p < .001), ischemic type biliary lesions (OR 0.112, 95% CI 0.042-0.299, p < .001), graft loss (HR 0.371, 95% CI 0.267-0.516, p < .001), and patient death (HR 0.540, 95% CI 0.373-0.781, p = .001). Cold ischemia time (HR 1.004, 95% CI 1.001-1.007, p = .021) and re-transplantation indication (HR 9.552, 95% CI 3.519-25.930, p < .001) were significant independent predictors for graft loss among cDCD livers with A-NRP. While use of A-NRP helps overcome traditional limitations in cDCD liver transplantation, opportunity for improvement remains for cases with prolonged cold ischemia and/or technically complex recipients, indicating a potential role for complimentary ex situ perfusion preservation techniques.

Abstract
OBJECTIVE To assess the incidence and significance of invasive fungal diseases (IFD) during veno-venous (VV) ECMO support for acute respiratory distress syndrome (ARDS). METHODS Retrospective analysis from January 2013 to April 2021 of all ECMO cases for ARDS at a German University Hospital. In patients with IFD (IFD patients), type of IFD, time of IFD, choice of antifungal agent, duration, and success of therapy were investigated. For comparison, patients without IFD (non-IFD patients) were selected by propensity score matching using treatment-independent variables (age, gender, height, weight, and the Sequential Organ Failure Assessment (SOFA) score at ICU admission). Demographics, hospital and ICU length of stay, duration of ECMO therapy, days on mechanical ventilation, prognostic scores (Charlson Comorbidity Index (CCI), Therapeutic Intervention Scoring System (TISS), and length of survival were assessed. RESULTS A total of 646 patients received ECMO, 368 patients received VV ECMO. The incidence of IFD on VV ECMO was 5.98%, with 5.43% for Candida bloodstream infections (CBSI) and 0.54% for invasive aspergillosis (IA). In IFD patients, in-hospital mortality was 81.8% versus 40.9% in non-IFD patients. The hazard ratio for death was 2.5 (CI 1.1-5.4; p: 0.023) with IFD. CONCLUSIONS In patients on VV ECMO for ARDS, about one in 17 contracts an IFD, with a detrimental impact on prognosis. Further studies are needed to address challenges in the diagnosis and treatment of IFD in this population.

Abstract
Patients with novel coronavirus 2019 (COVID-19) may develop acute respiratory distress syndrome (ARDS) and require extracorporeal membrane oxygenation (ECMO) support. Currently there is no specific treatment for COVID-19 available; thus, for patients with severe ARDS, the respiratory condition needs to improve while on ECMO support. Here we present a multidisciplinary team approach to the care of a patient with COVID-related ARDS requiring three months of veno-venous (VV) ECMO which lead to recovery. A 35-year-old male was transferred to us with ARDS due to COVID-19 infection with a lactate 13.7 mmol/L and an arterial-blood gas oxygenation of 75 mmHg on maximum ventilator settings. He was placed on VV ECMO during which he developed pneumonia, bacteremia, and pneumothoraces; however, his other organ functions were preserved. During his time in the Intensive Care Unit (ICU), multiple subspecialist teams participated in his care including physicians, pharmacists, nurses, nutritionists, case management, and social work. The VV ECMO was weaned off after 91 days of support, after which he had a prolonged hospital course due to inflammatory bowel disease, and aspiration pneumonia. CT scan performed six weeks prior to discharge showed mild improvement in diffuse airspace opacities superimposed on extensive chronic cystic changes. He was eventually discharged to a rehabilitation facility 68 days after ECMO removal. He was then seen in our outpatient pulmonary clinic one month and our Post-Intensive Care Syndrome clinic three months after discharge on two liters of nasal cannula oxygen. Pulmonary function testing done at this time demonstrated severe restrictive lung disease and severely reduced diffusion capacity. This case highlights the need for multidisciplinary collaboration among hospital teams to ensure success and patient survival in the setting of COVID ARDS. In those COVID ARDS patients with intact renal, metabolic, hematologic, and cardiovascular function, ECMO should be strongly considered.

Abstract
The aim of this qualitative systematic review is to summarize and analyze the different modalities of exercise training and its potential effects in patients on extracorporeal membrane oxygenation (ECMO) support. ECMO is an outbreaking, life-saving technology of the last decades which is being used as a gold standard treatment in patients with severe cardiac, respiratory or combined cardiorespiratory failure. Critically ill patients on ECMO very often present intensive care unit-acquired weakness (ICU-AW); thus, leading to decreased exercise capacity and increased mortality rates. Early mobilization and physical therapy have been proven to be safe and feasible in critically ill patients on ECMO, either as a bridge to lung/heart transplantation or as a bridge to recovery. Rehabilitation has beneficial effects from the early stages in the ICU, resulting in the prevention of ICU-AW, and a decrease in episodes of delirium, the duration of mechanical ventilation, ICU and hospital length of stay, and mortality rates. It also improves functional ability, exercise capacity, and quality of life. Rehabilitation requires a very careful, multi-disciplinary approach from a highly specialized team from different specialties. Initial risk assessment and screening, with appropriate physical therapy planning and exercise monitoring in patients receiving ECMO therapy are crucial factors for achieving treatment goals. However, more randomized controlled trials are required in order to establish more appropriate individualized exercise training protocols.

Abstract
Background: Large animal models are developed to help understand physiology and explore clinical translational significance in the continuous development of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) technology. The purpose of this study was to investigate the establishment methods and management strategies in an ovine model of VA-ECMO. Methods: Seven sheep underwent VA-ECMO support for 7 days by cannulation via the right jugular vein and artery. The animals were transferred into the monitoring cages after surgery and were kept awake after anesthesia recovery. The hydraulic parameters of ECMO, basic hemodynamics, mental state, and fed state of sheep were observed in real time. Blood gas analysis and activated clotting time (ACT) were tested every 6 h, while the complete blood count, blood chemistry, and coagulation tests were monitored every day. Sheep were euthanized after 7 days. Necropsy was performed and the main organs were removed for histopathological evaluation. Results: Five sheep survived and successfully weaned from ECMO. Two sheep died within 24-48 h of ECMO support. One animal died of fungal pneumonia caused by reflux aspiration, and the other died of hemorrhagic shock caused by bleeding at the left jugular artery cannulation site used for hemodynamic monitoring. During the experiment, the hemodynamics of the five sheep were stable. The animals stayed awake and freely ate hay and feed pellets and drank water. With no need for additional nutrition support or transfusion, the hemoglobin concentration and platelet count were in the normal reference range. The ECMO flow remained stable and the oxygenation performance of the oxygenator was satisfactory. No major adverse pathological injury occurred. Conclusions: The perioperative management strategies and animal care are the key points of the VA-ECMO model in conscious sheep. This model could be a platform for further research of disease animal models, pathophysiology exploration, and new equipment verification.

Abstract
Neonatal myocardial infarction due to coronary thrombus is a rare cause of acute heart failure and is associated with high morbidity and mortality. We present a rare case of a full-term newborn who developed coronary artery thrombus treated with intracoronary recombinant tissue plasminogen activator infusion while undergoing therapeutic hypothermia. Also, we describe a unique treatment strategy to support systemic circulation sparing the patient from neonatal extracorporeal membrane oxygenation and its complications. Neonatal myocardial infarction should be suspected and ruled out in sick newborns.

Extracorporeal Membrane Oxygenation After Norwood Surgery in Patients With Hypoplastic Left Heart Syndrome: A Retrospective Single-Center Cohort Study From Brazil. Front Pediatr 2022; 10:813528. [PMID: 35311057 PMCID: PMC8926323 DOI: 10.3389/fped.2022.813528] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 01/11/2022] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Extracorporeal membrane oxygenation (ECMO) is increasingly being used to support patients after the repair of congenital heart disease. OBJECTIVE We report our experience with patients with a single functional ventricle who were supported by ECMO after the Norwood procedure, reviewing the outcomes and identifying risk factors for mortality in these patients. METHODS In this single-center retrospective cohort study, we enrolled 33 patients with hypoplastic left heart syndrome (HLHS) who received ECMO support after the Norwood procedure between January 2015 and December 2019. The independent variables evaluated in this study were demographic, anatomical, and those directly related to ECMO support (ECMO indication, local of initiation, time under support, and urinary output while on ECMO). The dependent variable was survival. A p < 0.05 was considered statistically significant. RESULTS The ECMO support was applied in 33 patients in a group of 120 patients submitted to Norwood procedure (28%). Aortic atresia was present in 72.7% of patients and mitral atresia in 51.5%. For 15% of patients, ECMO was initiated in the operating room; for all other patients, ECMO was initiated in the intensive care unit. The indications for ECMO in the cardiac intensive care unit were cardiac arrest in 22 (79%) of patients, low cardiac output state in 10 (18%), and arrhythmia in 1 patient (3%). The median time under support was 5 (2-25) days. The median follow-up time was 59 (4-150) days. Global survival to Norwood procedure was 90.9% during the 30-day follow-up, being 33.3% for those submitted to ECMO. Longer ECMO support (p = 0.004) was associated with a higher risk of death in the group submitted to ECMO. CONCLUSIONS The mortality of patients with HLHS who received ECMO support after stage 1 palliation was high. Patients with low urine output were related to worse survival rates, and longer periods under ECMO support (more than 9 days of ECMO) were associated with 100% mortality. Earlier ECMO initiation before multiorgan damage may improve results.

Abstract
Technological advancements and rapid expansion in the clinical use of extracorporeal life support (ECLS) across all age ranges in the last decade, including during the COVID-19 pandemic, has led to important ethical considerations. As a costly and resource intensive therapy, ECLS is used emergently under high stakes circumstances where there is often prognostic uncertainty and risk for serious complications. To develop a research agenda to further characterize and address these ethical dilemmas, a working group of specialists in ECLS, critical care, cardiothoracic surgery, palliative care, and bioethics convened at a single pediatric academic institution over the course of 18 months. Using an iterative consensus process, research questions were selected based on: (1) frequency, (2) uniqueness to ECLS, (3) urgency, (4) feasibility to study, and (5) potential to improve patient care. Questions were categorized into broad domains of societal decision-making, bedside decision-making, patient and family communication, medical team dynamics, and research design and implementation. A deeper exploration of these ethical dilemmas through formalized research and deliberation may improve equitable access and quality of ECLS-related medical care.

Abstract
OBJECTIVE Extracorporeal membrane oxygenation (ECMO) is a widely used treatment for circulatory and pulmonary support in newborns and young children. Over the past decade, the number of children successfully treated with ECMO has gradually increased. However, despite an increasing number of survivors, new morbidity and long-term health issues are becoming more prevalent. A better understanding of the pediatric ECMO prognosis contributes to improved treatment and care programs and minimizes the risk of sequelae and dysfunctions. We aimed to determine the incidence of new morbidity, prognoses, and follow-up data of survivors treated with ECMO in pediatric intensive care units (PICU) using the Functional Status Scale (FSS). METHODS We retrospectively collected and analyzed clinical data of patients in the PICU who received ECMO from January 2016 to January 2020. Clinical and functional outcomes were assessed at admission and discharge using the FSS. Twenty-seven patients aged between 1 month and 14 years who received ECMO in the PICU were included. Fifty-two percent were male, and the median age was 36 months (interquartile range, 21-114 months). The patients were admitted for fulminant myocarditis (n = 13), acute respiratory distress syndrome (ARDS) (n = 11), and septic shock (n = 3). RESULTS This study reviewed a single-center experience using the FSS for ECMO treatment in a PICU. The patients' original conditions included fulminant myocarditis, ARDS, and septic shock. Of the 27 patients who received ECMO, 9 (33%) died, 12 (67%) showed improved condition, and 6 (33%) discontinued treatment and left the hospital. Furthermore, the following adverse events were observed in the survivors who were discharged: nine (50%) cases of lower extremity deep vein thrombosis, seven (39%) jugular vein thrombosis, six (33%) acute kidney injury, five (27%) intracranial hemorrhage and cerebral infarction, and one each of (6% each) pulmonary embolism and peripheral nerve injury. Of the 12 patients who survived through 1 year after discharge, five (42%) recovered completely, whereas seven (58%) showed mild to moderate communication and motor dysfunction. The short-term survival rate and 1-year survival rate of ECMO patients were 67% (18/27) and 44% (12/27), respectively. Additionally, approximately one-third of the patients developed a new morbidity after ECMO treatment (6/18). CONCLUSIONS High mortality and new morbidity were common in patients who received ECMO treatment. New morbidity increased the risk of death and exacerbated the functional state. Follow-up and rehabilitation after discharge are essential to achieve positive outcomes.

Abstract
Background: Extracorporeal membrane oxygenation (ECMO) life support has become an integral part of intensive care. The endotoxin activity assay (EAA) is a useful test to measure endotoxemia severity in whole blood. To date, no information is available regarding the EAA levels and their effect on clinical outcomes in critically ill patients with ECMO support. Methods: This prospective observational pilot study enrolled adult critically ill patients with ECMO support from August 2019 to December 2020. The EAA levels were measured within 24 h (T1), and at 25–48 (T2), 49–72 (T3), and 73–96 h (T4) after ECMO initiation. This study primarily aimed to investigate the incidence of high EAA levels (≥0.6) at each time point. Subsequent exploratory analyses were conducted to compare the EAA levels of venoarterial ECMO (VA-ECMO) patients between 30-day survivors and non-survivors. Post-hoc analysis was performed to compare the clinical outcomes of VA-ECMO patients with elevated EAA levels at T3 (vs. T1) and those without elevated EAA levels. Results: A total of 39 VA-ECMO patients and 15 venovenous ECMO (VV-ECMO) patients were enrolled. At T1, the incidence of high EAA level (≥0.6) was 42% in VV-ECMO patients and 9% in VA-ECMO patients (P = 0.02). At T2, the incidence of high EAA level was 40% in VV-ECMO patients and 5% in VA-ECMO patients (P = 0.005). In VA-ECMO patients, EAA levels at T3 were significantly higher in 30-day non-survivors than in survivors (median [interquartile range]: 0.49 [0.37–0.93] vs. 0.31 [0.19–0.51], median difference 0.16 [95% confidence interval [CI], 0.02–0.31]; P = 0.024). Moreover, VA-ECMO patients with elevated EAA levels at T3 (vs. T1) had lower 30-day survival than patients without elevated EAA levels (39 vs. 83%, P = 0.026) and fewer ECMO free days by day 30 (median: 3 vs. 23 days, median difference 12 days [95% CI, 0–22]; P = 0.028). Conclusions: A certain proportion of patients experienced high EAA levels (≥0.6) after VV-ECMO or VA-ECMO initiation. VA-ECMO patients with an elevated EAA level at 49–72 h were associated with poor clinical outcomes.

Abstract
Veno-venous extracorporeal membrane oxygenation is increasingly used for severe but potentially reversible acute respiratory failure in adults; however, there are limited data regarding long-term morbidity. At our institution, most patients requiring veno-venous extracorporeal membrane oxygenation have been followed up by a single physician. Our primary aim was to describe the serial long-term morbidity for respiratory, musculoskeletal and psychological functioning. A retrospective audit of inpatient and outpatient medical records was conducted. A total of 125 patients treated with veno-venous extracorporeal membrane oxygenation for primary respiratory failure were included. The patients were young (mean (standard deviation) age 43.7 (4.1) years), obese (mean (standard deviation) body mass index 30.8 (10.4) kg/m2), and mostly were male (59%). Most patients (60%) had no comorbidities. The survival rate to discharge was 70%, with body mass index and the number of comorbidities being independent predictors of survival on multiple logistic regression analysis. Over half (57%) of the Australian survivors had regular outpatient follow-up. They had a median of three reviews (range 1-9) over a median of 11.8 months (range 1.5-79) months. Breathlessness and weakness resolved in most within six months, with lung function abnormalities taking longer to resolve. Over half (60%) returned to employment within six months of discharge. Over a quarter (29%) displayed symptoms of anxiety, depression or post-traumatic stress disorder.

Abstract
Background: The novel coronavirus disease 2019 (COVID-19) pandemic has become a global health crisis affecting over 200 countries worldwide. Extracorporeal membrane oxygenation (ECMO) has been increasingly used in the management of COVID-19-associated end-stage respiratory failure. However, the exact effect of ECMO in the management of these patients, especially with regards to complications and mortality, is unclear. Methods: This is the largest retrospective study of ECMO treated COVID-19 patients in China. A total of 50 ECMO-treated COVID-19 patients were recruited. We describe the main characteristics, the clinical features, ventilator parameters, ECMO-related variables and management details, and complications and outcomes of COVID-19 patients with severe acute respiratory distress syndrome (ARDS) that required ECMO support. Results: For those patients with ECMO support, 21 patients survived and 29 died (mortality rate: 58.0%). Among those who survived, PaO2 (66.3 mmHg [59.5–74.0 mmHg] and PaO2/FiO2 (68.0 mmHg [61.0–76.0 mmHg]) were higher in the survivors than those of non-survivors (PaO2: 56.8 mmHg (49.0–65.0 mmHg), PaO2/FiO2 (58.2 mmHg (49.0–68.0 mmHg), all P < 0.01) prior to ECMO. Patients who achieved negative fluid balance in the early resuscitation phase (within 3 days) had a higher survival rate than those who did not (P = 0.0003). Conclusions: In this study of 50 cases of ECMO-treated COVID-19 patients, a low PO2/FIO2 ratio before ECMO commencement may indicate a poor prognosis. Negative fluid balance in the early resuscitation phase during ECMO treatment was a predictor of increased survival post-ECMO treatment.

Abstract
Background: Infection of Chlamydia psittaci (C. psittaci) could lead to serious clinical manifestations in humans, including severe pneumonia with rapid progression, adult respiratory distress syndrome (ARDS), sepsis, multiple organ dysfunction syndromes (MODS), and probably death. Implementation of extracorporeal membrane oxygenation (ECMO) in the patient with severe ARDS gives a promising new method for recovery. Case Presentation: We report our successful use of venovenous (VV) ECMO in a 48-year-old man who manifested with severe respiratory distress syndrome, acute kidney injury, and septic shock caused by a diagnosis of pneumonia. After the combination of therapy including anti-infection, mechanical ventilation, and continuous renal replacement therapy (CRRT), acute inflammatory syndrome developed. However, his respiratory status rapidly deteriorated. Then, venoarterial (VA)-ECMO support was placed on the patient as suddenly slowing of the heart rate. Harlequin (North-South) syndrome occurred after ECMO initiation. A series of the process could not relieve hypoxia in the upper body. At last, transition to VV-ECMO improved hypoxia. The duration of VV-ECMO was 7 days and the mechanical ventilation was weaned on the next day. On the day of ECMO weaning, nanopore targeted sequencing (NTS) of bronchoalveolar lavage fluid (BALF) reported the presence of C. psittaci. After 19 days of critical systemic rehabilitation and combination therapy, the patient fully recovered from C. psittaci. Conclusion: This is the first reported case of the patient receiving ECMO for C. psittaci pneumonia. ECMO puts the lungs on temporary rest, promotes the recovery of pulmonary function, and also wins time for finding the pathogens, which is crucial in the treatment of rare pathogens.

Abstract
Introduction. Brain injury is a major determinant of outcomes in extracorporeal membrane oxygenation (ECMO). Neurologic prognostication in ECMO has not been established. Absent electroencephalogram (EEG) reactivity and absent N20 on somatosensory evoked potential (SSEP) are associated with poor outcome in other types of brain injuries, especially following cardiopulmonary arrest. It is currently known if the same criteria are applicable in patients on ECMO. Methods. Continuous EEG (cEEG) was performed for patients with a Glasgow Coma Scale (GCS) <8 and SSEP data were performed for patients with a motor GCS < 4 in a prospective observational cohort undergoing ECMO at a tertiary center. EEG variables including reactivity were collected. SSEPs were categorized into absence, delay, or presence of N20. Poor outcome was defined as cerebral performance category 3 to 5 at discharge. Results. We present 13 consecutive patients who underwent both cEEG and SSEP. The median time from cannulation to EEG and SSEP were 3 (interquartile range [IQR] = 1-6) and 5 (IQR = 2-7) days, respectively. All patients were in coma and 12 (92%) had poor outcomes. Ten (77%) underwent brain computed tomography, the findings of which explained coma in only 2. Patients (n = 12) with poor outcome had poor variability, absent reactivity, and lack of sleep features with diffusely slow theta-delta background on the EEG. Despite poor outcomes, all had relatively preserved or normal N20 responses. One patient with preserved reactivity and sleep features on the EEG and intact SSEP had a good outcome. Conclusions. Absent EEG reactivity with the preservation of SSEP N20 was associated with poor outcome in comatose ECMO patients. We advise caution in interpreting electrophysiological tests in prognosticating ECMO patients until the patterns and outcomes are better understood.

Abstract
Background: Clinically amyopathic dermatomyositis (CADM) presented with rapid progressive interstitial lung disease (RP-ILD) is rare. Here, we present a case of a post-partum female with CADM complicated by severe RP-ILD managed with venovenous extracorporeal membrane oxygenation (V-V ECMO). Case Summary: A 36-year-old woman was referred to a local hospital with cough and fever. She had a history of facial erythema and cough since an induction of labor for a stillborn fetus 2 months ago. Her status developed into RP-ILD with mediastinal emphysema and subcutaneous emphysema after admission, and V-V ECMO was initiated. After several failed attempts to wean the patient from ECMO, a decision was made to place the patient on the lung transplant waitlist. She underwent a double lung transplant on ECMO day 31 and received tacrolimus as an immunosuppressive regimen. The patient presented with positive anti-MDA5 and anti-Ro-52 antibodies and a high ferritin level, all of which indicated the presence of clinically amyopathic dermatomyositis (CADM). The patient was weaned from ECMO at 3 days after transplantation, but the patient's state of consciousness deteriorated, and head CT was considered for posterior reversible encephalopathy syndrome (PRES). After the temporary cessation of calcineurin inhibitors and a dosage reduction, the patient's state of consciousness returned to normal. Because of another disturbance of consciousness, the patient declined further treatment and was discharged 14 days after transplantation. Conclusion: Early recognition of CADM can effectively improve patients' prognosis. ECMO should be considered as a supportive therapy in patients in acute respiratory failure secondary to RP-ILD.

Abstract
Pregnant women with influenza-A have an increased risk of developing acute respiratory distress syndrome (ARDS). Extracorporeal membrane oxygenation (ECMO) can be used as salvage therapy, with lung transplantation as a therapeutic option. However, successful bilateral lung transplantation during pregnancy has never been reported before. We herein report the case of a 34-year-old primipara, who was diagnosed with ARDS caused by influenza-A-induced pneumonia at early gestation. After considering all possible therapeutic options and being fully dependent on VV-ECMO support, she underwent bilateral lung transplantation. The transplantation with intraoperative central VA-ECMO support was successfully performed with good recovery after an initial primary graft dysfunction. The pregnancy was prolonged until 29+5 gestational weeks. The newborn exhibited growth retardation and was initially stabilized, but later died due to severe, hypoxic respiratory failure and pulmonary hypertension. In conclusion, lung transplantation is a possible salvage therapy for patients with severe lung failure following ARDS during pregnancy. However, it places the mother and unborn child at risk. A multi-professional approach is warranted to diagnose and treat complications at an early stage.

Abstract
Myocarditis refers to myocardial inflammatory damage, and it can have various causes. Myocarditis can lead to impaired cardiac function, including decreased systolic and diastolic function and arrhythmia. When myocarditis occurs suddenly and rapidly progresses to severe heart failure, hypotension, cardiogenic shock, or severe arrhythmia, it can be diagnosed as fulminant myocarditis (FM). Our hospital recently admitted a case of juvenile FM, a 17-year-old male, who was admitted to the hospital for “intermittent chest tightness and asthma for 10 days”. When the patient was hospitalized, he complained of chest tightness, palpitation, shortness of breath, fatigue, and dyspnea. Wet rales could be heard in both lungs on auscultation, as well as arrhythmia. Echocardiograms indicated an ejection fraction of 10%. Laboratory tests showed liver and kidney dysfunction as well as abnormal coagulation function. After admission, he was treated with drugs including cardiotonic, diuretic, hormonal, antiviral drugs, and drugs affecting immune regulation. After tracheal intubation-assisted ventilation, the patient’s symptoms did not significantly alleviate, and then veno-arterial extracorporeal membrane oxygenation (V-A ECMO) combined with an intra-aortic balloon pump (IABP) were used to assist in the treatment of cardiopulmonary failure. After the treatment, the patient’s hemodynamics were stable, the respiratory and circulatory functions were restored, and the ECMO and IABP were successfully removed. The patient’s review results were satisfactory, and he was discharged without delay. Although ECMO has no direct therapeutic effect on myocarditis, it can quickly stabilize hemodynamics, improve systemic tissue perfusion, reduce the use of high-dose vasoactive drugs and effectively assist patients during the acute phase of myocarditis. The authors believe that ECMO is the first choice for the treatment of FM in adolescents. Here we summarize our experience at our hospital with the treatment of FM using life support methods.
