This study analyzed early postoperative complications in 145 adult patients who received total intravenous anesthesia (TIVA) with propofol and remifentanil for elective neurosurgery. The authors found:
1) The overall incidence of shivering was 30.3%, postoperative nausea and vomiting (PONV) was 16.6%, and postoperative hypertension (blood pressure over 25% of preoperative value) was 35.2%.
2) 51% of patients experienced at least one of these complications. Complication rates varied significantly between surgical groups.
3) The intracranial vascular surgery group had the highest rates of shivering (58.8%) and PONV (29.4
