Filter by:The overall objective of this study is to test for perturbations in intraoperative electroencephalogram (EEG) , cerebral blood flow (CBF), cerebral metabolic rate of oxygen consumption (CMRO2), oxygen extraction fraction (OEF), and serum and cerebral spinal fluid biomarkers associated with delirium in high risk population having elective hip arthroplasty at Penn Presbyterian Medical Center (PPMC).
At Wake Forest University, the investigators have been using Extended Release Epidural Morphine (EREM), since late 2004, as part of multimodal analgesia in patients having gynecologic surgeries and hip arthroplasties. Hypothesis: In patients undergoing a Birmingham total hip arthroplasty (BHA), low dose EREM in conjunction with lumbar plexus block (LPB) will be better than lumbar plexus block alone in increasing proportion of patients who meet discharge criteria within 24 hours.
Chronic pain in patients following total hip replacement seems to be a significant problem. Previous research has shown that more effective pain management in the early postoperative period may decrease the incidence of the development of chronic pain states. This study will evaluate whether ketorolac (a non steroidal anti-inflammatory drug) given into the spinal fluid before surgery will reduce the area of sensitivity (or pain to light touch) following surgery. Patients will be monitored during their postoperative hospital stay and then contacted by telephone at 8 weeks and 6 months after surgery and questioned about any pain they are having at their surgical site. Patients that are still experiencing pain at 6 months will be asked to return to the medical center for the study staff to assess their pain or sensitivity at the surgical site.
