Review Article: Management of Perioperative Anesthesia in Right Heart Failure

Right ventricular dysfunction and failure receive much less attention than the left ventricular failure. Right ventricular dysfunction or failure is associated with increased mortality rates in cardiac surgery, surgical cases other than cardiac surgery and also in patients treated in the ICU. The purpose of this article review was to describe the anatomy, physiology and pathophysiology of right ventricular failure, its detection and diagnosis, and management considerations from anesthetic point of view, including preoperative, intraoperative and postoperative stages. Cardiac surgery may result in right ventricular failure. For example, 0.1% post cardiotomy patients experience severe right heart failure and require long-term inotropic support, and so do 2-3% of post-transplant patients, and 20-30% of patients installed with instrument in his left heart. Therefore, anesthesiologists play a major role in perioperative and postoperative intensive care and are obliged to comprehend the nature of right ventricular dysfunction and failure so as to carry out early detection, prevent and manage patients with right ventricular dysfunction

Characteristics and outcomes of patients with severe COVID-19 in Indonesia: Lessons from the first wave.

BackgroundIndonesia's national response to COVID-19 evolved rapidly throughout 2020. Understanding pandemic response and outcomes is crucial for better mitigation strategies ahead. This study describes the characteristics and outcomes of patients admitted to ICU during the early stages of the pandemic.MethodsThis is a multi-centre prospective observational study including patients from twelve collaborating hospitals in Indonesia. All patients were clinically suspected or laboratory-confirmed COVID-19 cases admitted to ICU between January 2020 and March 2021. The primary outcome was monthly ICU mortality. Descriptive statistics of patient characteristics and treatment were generated as secondary outcomes.ResultsFrom 559 subjects, the overall mortality was 68% and decreased over the study period, while the mortality of patients that received mechanical ventilation was 92%, consistently high over the study period. Fatal cases showed 2- and 4-day delays from symptoms onset to hospital admissions and ICU admissions, respectively. Evidence-backed approaches which could influence patient outcome, such as extracorporeal membrane oxygenation, prone positioning, renal replacement therapy, and neuromuscular blockade were scarcely administered.ConclusionsThe mortality rate of COVID-19 patients in Indonesia was extremely high during the first major outbreak of disease, particularly in those mechanically ventilated. Delayed admission and unavailability of evidence-based approaches due to high burden on health facility during COVID-19 crisis could be addressed by efficient public health measures and enhancing health infrastructure to improve the future pandemic response
