Incidence and factors associated with postoperative hemodynamic change in the postanaesthetic care unit among adult surgical patients at a tertiary care hospital in Ethiopia: a prospective observational study

In general, 93 study subjects (22.7%) experienced advanced haemodynamic instability during the intraoperative period. This implies that the incidence of hemodynamic instability was high. Intraoperative haemodynamic instability, American Society of Anaesthesiology class III, postoperative respiratory adverse events, neurologic and gynaecological procedures, use of neuraxial anaesthesia, and prolonged duration of procedures were predictors of haemodynamic instability in the postanaesthesia care unit.
