Intravenous patient-controlled analgesia versus epidural anesthesia in the treatment of patients undergoing total hip arthroplasty: a retrospective comparative study

The results reveal that patient-controlled epidural analgesia offers superior pain relief, lower side effects, better post-operative analgesic effect, and better postoperative recovery. Patient-controlled epidural analgesia shows great promising clinical application potential for anesthesia after total hip arthroplasty.
