This approach has been design ed to provide adequate analgesia while minimizing exposure to adverse events
Background : Laparoscopic cholecystectomy has advantages over the open procedure for postoperative pain .
However , a systematic review of postoperative pain management in this procedure has not been conducted .
A randomized comparison of patient-controlled versus standard analgesic requirements in patients undergoing cholecystectomy.
In the current study , 55 patients undergoing elective cholecystectomy were r and omly allocated to receive postoperative analgesia ( morphine sulfate ) administered through either  patient-controlled intravenous ( PCA ) or st and ard intramuscular ( IM ) routes . There were no significant differences in length of hospitalization or required dose of morphine sulfate . Patients r and omized to PCA reported significantly improved subjective relief from pain and a smaller percentage of time in pain during each of the first two postoperative days . In addition , they reported less sedation and less interference with both postoperative breathing and pulmonary recovery than patients who received IM morphine . Theoretically , PCA regimens can deliver narcotic analgesia at a higher and more varied rate ( with fewer side effects ) compared with st and ard IM narcotic delivery , which is more limited by considerations of clinical doses . In PCA dosing , patients should experience less time in pain and sedation . The results of the current study support this premise
