RESUMO
AIM: To observe the effect of continuous epidural analgesia (CEA) of tramadol on postoperative gastrointestinal function and serum motilin level in the patients with cholecystectomy. METHODS: Twenty eight ASAⅠ-Ⅱpatients (8 male, 20 female) aged 24-56 yr, scheduled for elective cholecystectomy under epidural anesthesia, were randomly divided into tramadol group (T, n=14) and control group (C, n=14). The combination of tramadol 800 mg+ bupivacaine 150 mg+ droperidol 5 mg, which diluted with normal saline to 100 ml and pumped 2 ml?h -1, was administered in group T. The combination in group C was bupivacaine 150 mg+ droperidol 5 mg. The VAS values, the first anorectum exhaust timing (FAET), and the time of the first eliminating stool timing (FEST) were recorded, and serum motilin level measured with radioimmunoassay at the different times after surgery. RESULTS: There was a significant difference in the mean VAS values between group T ( 1.2? 1.2) and group C ( 3.3? 1.3) (P
