Surprise Finding: For Very Sick Elderly, Lighter Sedation Won’t Drop Risk of Postoperative Delirium, Study Suggests

Johns Hopkins Medicine researchers say a study designed to see if reducing the amount of anesthesia reduces the risk of postoperative delirium in older patients   surprisingly found that lighter sedation failed to do so in severely ill people undergoing hip fracture repair.

But the study of 200 men and women also showed that for those in relatively better health, deep sedation more than doubled the risk of postoperative delirium compared with those having light sedation.
