Abstract
Postoperative pain is a major concern after total knee arthroplasty and other major knee surgery. It is severe in 60% of patients and moderate in 30%. When inadequately treated, it intensifies reflex responses, which can cause serious complications (Shoji et al., 1999). In the recent study we will control the postoperative pain by three different analgesic techniques which are continuous epidural infusion (CEI) using mixture of lidocaine, morphine, and epinephrine; intravenous morphine using patient controlled analgesia; and continuous femoral (lumbar plexus) block (CFB). Although, the epidural analgesia remains the reference technique (Capdevila et al., 1999), it has many side effects which necessitate studying another techniques which are more easer and safer. We suggest that CFB technique will give comparable analgesia to CEI with only few minor adverse effects thus providing the best balance of analgesia and side effects. We use also i.v. PCA with morphine as it is a new technique in our university to study its efficacy, safety, and versatility. Also, to study the acceptance and satisfaction of Egyptian patients to the idea of auto control upon their pain.
