Introduction: The pandemic of the coronavirus disease 2019 (COVID-19) and associated pneumonia represent a clinical and scientific challenge. The role of Extracorporeal Membrane Oxygenation (ECMO) in such a crisis remains unclear. Methods: We examined COVID-19 patients who were supported for acute respiratory failure by both conventional mechanical ventilation (MV) and ECMO at a tertiary care institution in Washington DC. The study period extended from March 23 to April 29. We identified 59 patients who required invasive mechanical ventilation. Of those, 13 patients required ECMO. Results: Nine out of 13 ECMO (69.2%) patients were decannulated from ECMO. All-cause ICU mortality was comparable between both ECMO and MV groups (6 patients [46.15%] vs. 22 patients [47.82 %], p = 0.92). ECMO non-survivors vs survivors had elevated D-dimer (9.740 mcg/ml [4.84-20.00] vs. 3.800 mcg/ml [2.19-9.11], p = 0.05), LDH (1158 ± 344.5 units/L vs. 575.9 ± 124.0 units/L, p = 0.001), and troponin (0.4315 ± 0.465 ng/ml vs. 0.034 ± 0.043 ng/ml, p = 0.04). Time on MV as expected was significantly longer in ECMO groups (563.3 hours [422.1-613.9] vs. 247.9 hours [101.8-479] in MV group, p = 0.0009) as well as ICU length of stay 576.2 hours [457.5-652.8] in ECMO group vs. 322.2 hours [120.6-569.3] in MV group, p = 0.012). Conclusion: ECMO is a supportive intervention for COVID-19 associated pneumonia that could be considered if the optimum mechanical ventilation is deemed ineffective. Biomarkers such as D-dimer, LDH, and troponin could help with discerning the clinical prognosis in patients with COVID-19 pneumonia.

Background: We aimed to use the Extracorporeal Life Support Organization registry to describe the current practice of rest mechanical ventilation setting in children receiving veno-venous extracorporeal membrane oxygenation (V-V ECMO) and to determine if relationships exist between ventilator settings and mortality. Methods: Data for patients 14 days to 18 years old who received V-V ECMO from 2012-2016 were reviewed. Mechanical ventilation data available includes mode and settings at 24 h after ECMO cannulation. Multivariable logistic regression analysis was performed to determine if rest settings were associated with mortality. Results: We reviewed 1161 subjects, of which 1022 (88%) received conventional mechanical ventilation on ECMO. Rest settings, expressed as medians (25th%, 75th%), are as follows: rate 12 breaths/minute (10, 17); peak inspiratory pressure (PIP) 22 cmH2O (20,27); positive end expiratory pressure (PEEP) 10 cmH2O (8, 10); and fraction of inspired oxygen (FiO2) 0.4 (0.37, 0.60). Survival to discharge was 68%. Higher ventilator FiO2 (odds ratio:1.13 per 0.1 increase, 95% confidence interval:1.04, 1.23), independent of arterial oxygen saturation, was associated with mortality. Conclusions: Current rest ventilator management for children receiving V-V ECMO primarily relies on conventional mechanical ventilation with moderate amounts of PIP, PEEP, and FiO2. Further study on the relationship between FiO2 and mortality should be pursued.

Abstract Background Duration of invasive mechanical ventilation (IMV) prior to extracorporeal membrane oxygenation (ECMO) affects outcome in acute respiratory distress syndrome (ARDS). In coronavirus disease 2019 (COVID-19) related ARDS, the role of pre-ECMO IMV duration is unclear. This single-centre, retrospective study included critically ill adults treated with ECMO due to severe COVID-19-related ARDS between 01/2020 and 05/2021. The primary objective was to determine whether duration of IMV prior to ECMO cannulation influenced ICU mortality. Results During the study period, 101 patients (mean age 56 [SD ± 10] years; 70 [69%] men; median RESP score 2 [IQR 1–4]) were treated with ECMO for COVID-19. Sixty patients (59%) survived to ICU discharge. Median ICU length of stay was 31 [IQR 20.7–51] days, median ECMO duration was 16.4 [IQR 8.7–27.7] days, and median time from intubation to ECMO start was 7.7 [IQR 3.6–12.5] days. Fifty-three (52%) patients had a pre-ECMO IMV duration of > 7 days. Pre-ECMO IMV duration had no effect on survival (p = 0.95). No significant difference in survival was found when patients with a pre-ECMO IMV duration of < 7 days (< 10 days) were compared to ≥ 7 days (≥ 10 days) (p = 0.59 and p = 1.0). Conclusions The role of prolonged pre-ECMO IMV duration as a contraindication for ECMO in patients with COVID-19-related ARDS should be scrutinised. Evaluation for ECMO should be assessed on an individual and patient-centred basis.

Background: The data on long-term outcomes of patients infected by SARS-CoV-2 and treated with extracorporeal membrane oxygenation (ECMO) in China are merely available.Methods: A retrospective study included 73 patients infected by SARS-CoV-2 and treated with ECMO in 21 intensive care units in Hubei, China. Data on demographic information, clinical features, laboratory tests, ECMO durations, complications, and living status were collected.Results: The 73 ECMO-treated patients had a median age of 62 (range 33–78) years and 42 (63.6%) were males. Before ECMO initiation, patients had severe respiratory failure on mechanical ventilation with a median PO2/FiO2 of 71.9 [interquartile range (IQR), 58.6–87.0] mmHg and a median PCO2 of 62 [IQR, 43–84] mmHg on arterial blood analyses. The median duration from symptom onset to invasive mechanical ventilation, and to ECMO initiation was19 [IQR, 15–25] days, and 23 [IQR, 19–31] days. Before and after ECMO initiation, the proportions of patients receiving prone position ventilation were 58.9 and 69.9%, respectively. The median duration of ECMO support was 18.5 [IQR 12–30] days. During the treatments with ECMO, major hemorrhages occurred in 31 (42.5%) patients, and oxygenators were replaced in 21 (28.8%) patients. Since ECMO initiation, the 30-day mortality and 60-day mortality were 63.0 and 80.8%, respectively.Conclusions: In Hubei, China, the ECMO-treated patients infected by SARS-CoV-2 were of a broad age range and with severe hypoxemia. The durations of ECMO support, accompanied with increased complications, were relatively long. The long-term mortality in these patients was considerably high.

Protective Ventilation Strategy

Conventionally, a substantial number of patients with acute respiratory failure require mechanical ventilation (MV) to avert catastrophe of hypoxemia and hypercapnia. However, mechanical ventilation per se can cause lung injury, accelerating the disease progression. Extracorporeal membrane oxygenation (ECMO) provides an alternative to rescue patients with severe respiratory failure that conventional mechanical ventilation fails to maintain adequate gas exchange. The physiology behind ECMO and its interaction with MV were reviewed. Next, we discussed the timing of ECMO initiation based on the risks and benefits of ECMO. During the running of ECMO, the protective ventilation strategy can be employed without worrying about catastrophic hypoxemia and carbon dioxide retention. There is a large body of evidence showing that protective ventilation with low tidal volume, high positive end-expiratory pressure, and prone positioning can provide benefits on mortality outcome. More recently, there is an increasing popularity on the use of awake and spontaneous breathing for patients undergoing ECMO, which is thought to be beneficial in terms of rehabilitation.

Abstract Background The clinical presentation of SARS-CoV-2 disease ranges from asymptomatic respiratory infection to acute respiratory distress syndrome. Risk factors upon hospital admission associated with the need for invasive mechanical ventilation are not well documented. Methods 185 hospitalized patients with confirmed COVID-19 were enrolled in this study, and they were classified as patients who required invasive mechanical ventilation and patients who did not require it. Comorbidities such as diabetes, high blood pressure, obesity, chronic lung disease and immunodeficiency were recorded. Laboratory studies were requested upon admission such as C-reactive protein, leukocyte and lymphocyte levels, D-dimer, troponin, serum ferritin and procalcitonin. Results Of the patients who entered the study, 65 patients (35%) required invasive mechanical ventilation (IMV), while 120 (65%) did not require advanced airway management. Of the patients with invasive mechanical ventilation, age &gt; 65 years, male sex, obesity (BMI &gt; 30) and high blood pressure were the most frequent characteristics, presenting the latter two in 26% and 27% respectively. Regarding laboratory studies, the parameters most associated with the requirement for mechanical ventilation were a D-dimer (&gt; 1000) and troponin (&gt; 1), with 26% and 18%, respectively. Conclusion This study showed the high proportion of obesity, hypertension and advanced age among patients who required invasive mechanical ventilation associated with SARS-CoV2 infection. The presence of elevated D-dimer and troponin on admission are associated with more severe presentations and a requirement for invasive mechanical ventilation.
