Awakening Early, Valve Heart Disease
Conditions
Brief summary
Cardiac surgery is a complex operative procedure with a substantial risk of postoperative complications, so that patients undergoing valve surgery are usually transferred to the intensive care unit postoperatively. Various substances are used to maintain the required sedation, such as volatile anaesthetics and intravenous sedatives combined with analgetic therapy using opioids. The study intends to investigate to what extent the already well-described effect of volatile anaesthetics on recovery can be realised despite the need for differentiated intensive care and medical management.
Interventions
Patients admitted after valve surgery are receiving intensive care using volatile sedative per anaesthetic conserving device. The subject of the study is medical and nursing time management..
