In this study we wanted to determine if perioperative administration of olanzapine prior to knee or hip replacement surgery in high risk patients would prevent the onset of postoperative delirium.
Postoperative delirium is a serious and common (20% to 60%) complication in orthopedic surgery patients. In this study we investigate whether prophylactic administration of olanzapine can prevent delirium from occurring after knee or hip replacement in high-risk patients > 65 years of age. This is a randomized, double-blind, single center, placebo-controlled study.
