Membrane Oxygenation

Myasthenia gravis is an autoimmune neuromuscular disease characterized by pathologically rapid fatigue of striated muscles [1]. The main symptom of myasthenia gravis is the presence of pathological muscle weakness with involvement of the ocular, bulbar and skeletal muscles in the pathological process. The provoking factors for the development of myasthenia gravis can be infectious diseases, surgery, drugs [2, 3]. The main danger is represented by myasthenic and cholinergic crises, which are characterized by a severe course and high mortality; therefore, the problems of treating myasthenia gravis are still of high medical and social significance. The prevalence of myasthenia gravis is 17.5–20.3 per 100 thousand population, and the number of patients is increasing by 5–10% annually [4, 5]. In recent years, there has been a steady increase in morbidity with an increase in age over 50 years [6, 7]. Myasthenia gravis is a serious disease with a high mortality rate of up to 30–40% [3]. There are difficulties in the early differential diagnosis of muscle weakness in patients with respiratory failure between myasthenia gravis, myasthenic syndrome and critical illness polyneuropathy. These difficulties and insufficient awareness of patients and doctors of various specialties about myasthenia gravis can lead to the choice of the wrong treatment tactics and the development of myasthenic crisis, which is manifested by respiratory failure, requiring respiratory support. The progression of respiratory failure against the background of myasthenic crisis may require the use of extracorporeal membrane oxygenation (ECMO).It is necessary to expand the differential diagnosis of muscle weakness in a patient during the period of resolution of respiratory failure, allowing to move away from compulsory respiratory support, termination of ECMO.

Lung disease is America’s third largest killer, and responsible for one in seven deaths [1]. Most lung disease is chronic, and respiratory support is essential. Current therapies for the respiratory failure include mechanical ventilation and bed-side extracorporeal membrane oxygenation (ECMO) devices which closely simulate the physiological gas exchange of the natural lung.

Membrane Oxygenation

Background: There are limited data regarding prolonged extracorporeal membrane oxygenation (ECMO) support, despite increase in ECMO use and duration in patients with respiratory failure. The objective of this study was to investigate the outcomes of severe acute respiratory failure patients supported with prolonged ECMO for more than 28 days. Methods: Between January 2012 and December 2015, all consecutive adult patients with severe acute respiratory failure who underwent ECMO for respiratory support at 16 tertiary or university-affiliated hospitals in South Korea were enrolled retrospectively. The patients were divided into two groups: short-term group defined as ECMO for ⩽28 days and long-term group defined as ECMO for more than 28 days. In-hospital and 6-month mortalities were compared between the two groups. Results: A total of 487 patients received ECMO support for acute respiratory failure during the study period, and the median support duration was 8 days (4–20 days). Of these patients, 411 (84.4%) received ECMO support for ⩽28 days (short-term group), and 76 (15.6%) received support for more than 28 days (long-term group). The proportion of acute exacerbation of interstitial lung disease as a cause of respiratory failure was higher in the long-term group than in the short-term group (22.4% versus 7.5%, p < 0.001), and the duration of mechanical ventilation before ECMO was longer (4 days versus 1 day, p < 0.001). The hospital mortality rate (60.8% versus 69.7%, p = 0.141) and the 6-month mortality rate (66.2% versus 74.0%, p = 0.196) were not different between the two groups. ECMO support longer than 28 days was not associated with hospital mortality in univariable and multivariable analyses. Conclusions: Short- and long-term survival rates among patients receiving ECMO support for more than 28 days for severe acute respiratory failure were not worse than those among patients receiving ECMO for 28 days or less.

Life Threatening

Extracorporeal membrane oxygenation (ECMO) is a technique involving oxygenation of blood and elimination of carbon dioxide in patients with life-threatening, but potentially reversible conditions. Thanks to the modification of extracorporeal circulation used during cardiac surgeries, this technique can be used in intensive care units. Venovenous ECMO is used as a respiratory support, while venoarterial ECMO as a cardiac and/or respiratory support. ECMO does not cure the heart and/or lungs, but it gives the patient a chance to survive a period when these organs are inefficient. In addition, extracorporeal membrane oxygenation reduces or eliminates the risk of lung damage associated with invasive mechanical ventilation in patients with severe ARDS (acute respiratory distress syndrome). ECMO is a very invasive therapy, therefore it should only be used in patients with extremely severe respiratory failure, who failed to respond to conventional therapies. According to the Extracorporeal Life Support Organization (ELSO) Guidelines, inclusion criteria are: PaO2 / FiO2 < 80 for at least 3 hours or pH < 7.25 for at least 3 hours. Proper ECMO management requires advanced medical care. This article discusses the history of ECMO development, clinical indications, contraindications, clinical complications and treatment outcomes.

Background Extracorporeal membrane oxygenation (ECMO) is a potential option for the management of severe acute respiratory failure secondary to COVID-19. Conflicting the use of this therapy is the known coagulopathy within COVID-19, leading to an incidence of venous thrombotic events of 25% to 49%. To date, limited guidance is available on optimal anticoagulation strategies in this population. Objective The purpose of this study was to evaluate the utilization of a pharmacist-driven bivalirudin dosing protocol for anticoagulation in the setting of ECMO for COVID-19–associated respiratory failure. Methods This was a single-center retrospective chart review over a 9-month period of patients receiving bivalirudin while on ECMO. All patients with acute respiratory failure requiring ECMO with a positive SARS-CoV-2 polymerase chain reaction were included. Bivalirudin was dosed via aPTT monitoring after a starting dose of 0.2 or 0.3 mg/kg/h. Results There were 33 patients included in this study, all receiving mechanical ventilation. The most common starting dose of bivalirudin was 0.2 mg/kg/h, with an average time to therapeutic range of 20 hours. Compared to previous reports, rates of bleeding were low at 15.1%, and 6.1% of patients developed a new venous thromboembolic event while on ECMO. ECMO survival was 51.5%, with an ICU mortality rate of 48.5%. Conclusion and Relevance In the first published report of its use within this population, bivalirudin was found to be a viable choice for anticoagulation in those patients on ECMO for severe respiratory failure secondary to COVID-19.

Large Randomized Trial

Extracorporeal membrane oxygenation (ECMO) has been used with increasing frequency to support patients with acute respiratory failure, most commonly, and severe forms of acute respiratory distress syndrome (ARDS). The marked increase in the global use of ECMO followed the publication of a large randomized trial in 2009 and the experience garnered during the 2009 influenza A (H1N1) pandemic, and has been further supported by the release of a large, randomized clinical trial in 2018, confirming a benefit from using ECMO in patients with severe ARDS. Despite a rapid expansion of ECMO-related publications, optimal management of patients receiving ECMO, in terms of patient selection, ventilator management, anticoagulation, and transfusion strategies, is evolving. Most recently, ECMO is being utilized for an expanding variety of conditions, including for cases of severe pulmonary or cardiac failure from coronavirus disease 2019 (COVID-19). This review evaluates modern evidence for ECMO for respiratory failure and the current challenges in the field.
