Abstract

Postcardiotomy cardiogenic shock occurs in 2-6% of patients undergoing cardiac surgery, and 1% of cardiac surgery patients will require mechanical circulatory support using venoarterial extracorporeal membrane oxygenation. Acute kidney injury is a frequent complication in this population and negatively impacts the survival. We aimed to determine whether the timing of extracorporeal membrane oxygenation implantation influences the renal prognosis of these patients. Retrospective observational cohort study between January 2013 and December 2016. An 18-bed surgical ICU in a university hospital. A total of 4,796 consecutive adult patients who underwent cardiac surgery were included in the study, and 347 (7.2%) were assisted with venoarterial extracorporeal membrane oxygenation for refractory postcardiotomy cardiogenic shock. The patients who died during the first 48 hours after venoarterial extracorporeal membrane oxygenation implantation were excluded. The complete-case analysis included 257 patients. None. The primary outcome was the occurrence, within 10 days following the venoarterial extracorporeal membrane oxygenation implantation, of a stage 3 acute kidney injury defined by the Kidney Disease: Improving Global Outcomes group...Continue Reading
