Purpose: Nalbuphin has definitive advantages over the more commonly used narcotic analgesic: a ceiling respiratory depression, little effect on the cardiovascular system and a lower incidence of nausea and vomiting. The use of a small incision<br>results<br>in early return of bowel function and shortening of hospital stay. Narcotic use has been felt to be proportional to the length of the abdominal incision. The aim of this study was to determine whether return of bowel function after colectomy in<br>the<br>postoperative period and incision length were directly proportional to the narcotics.<br>Methods: 38 patients undergoing colon and rectal resection for benign and malignant colorectal disease between July 2000 and April 2001 participated in this study. Nalbuphin and ketorolac was administered continually by patient controlled<br>analgesia<br>for<br>48 hours. Additional nalbuphin was used for further pain control. Patients were followed for return of bowel function as measured by first audible bowel sounds, first passage of flatus and first defecation.<br>Results: There was a significant correlation between the amount of total nalbuphin administered and return of bowel function as measured by bowel sound (r=0.89; P=0.01), time to first passage of flatus (r=0.76; P=0.01), and time to first<br>defecation<br>(r=0.58; P=0.05). Incision length did not show any correlation with either nalbuphin use or return of bowel function.<br>Conclusions: There is no apparent benefit for lesser incision length. Return of bowel function is influenced by use of postoperative nalbuphin. So adequate sized abdominal incision is needed and lesser use of narcotics is more beneficial for the<br>return<br>of bowel function.<br>
