Low intrathecal doses of opiates produce dose-dependent long-wasting elevation of the pain threshold in rats. The effect is postulated to be mediated by a direct action on the substantia gelatinosa of the spinal cord. Eight uncontrolled and two controlled studies in man showed a long duration of analgesia for most patients in the postoperative period. The duration of effect differs widely within and between studies. Using a double-blind design, we compared the relative efficacy of epidural and parenteral pethidine to control postoperative pain after total hip replacement. Preliminary pharmacokinetic data from six patients show that epidural doses of 20 or 60 mg pethidine give a similar pattern of absorption and elimination in plasma as 2 mg pethidine/kg body weight intramuscularly. The terminal elimination half-lives of pethidine in plasma are 5-7 h for all routes of administration. The possibility cannot be excluded that the analgesic effect of epidural pethidine is partly systemically mediated.
