Relationship between intra‐ and postoperative oxygen transport and prolonged intensive care after cardiac surgery: a prospective study

Background: Prolonged intensive care is a rare but serious complication of cardiac surgery. It is required in less than 10% of operated patients but they use more than 30% of all the intensive care resources needed for cardiac surgery. The aim of our study was to describe the clinical course of the patients who need prolonged intensive care following cardiac surgery and to assess whether the intra‐ and postoperative oxygen transport variables are different in these patients as compared to patients with an uncomplicated course.
