Spinal Anesthesia Vs. Neve Block in Risk of Cognitive Decline

Hip fracture is a potentially devastating event, and serious surgical and medical complications occur frequently especially for elderly patients. Delirium is one of the common complications after hip surgery. This study objective is to assess the association between type of anesthesia (nerve block vs. spinal anesthesia) and risk of cognitive decline (CD). And its secondary objective is to compare intra-operative hemodynamic changes, and post-operative pain. Prospective, double blind randomized clinical trial of hip fracture patients who will be assessed for CD pre- and postoperatively, for three months after surgery. Patients undergoing hip surgery will be randomized into two groups. Group 1 will receive unilateral lumbosacral nerve block (sciatic nerve block and paravertebral block at levels L3-L4 and L4-L5) as well as placebo injection (1 ml normal saline) at the spinal anesthesia level (L3-L4 or L4-L5). Group 2 will receive spinal anesthesia in addition to placebo injection at the sciatic, L3-L4 and L4-L5 levels.
