Abstract:Objective To investigate the effect of dezocine in the bundle for analgesia after cesarean section.? Methods A hundred cases of puerperae who received cesarean section under combined spinal-epidural anesthesia at ASA Ⅰ orⅡ were divided into dezocine group and control group (50 cases each). Both groups were given bundle for analgesia, including that the anesthesia level was T6 during the operation, the intravenous and epidural analgesia were given with bolus doses after the operation, and the patient-controlled intravenous analgesia(PCIA) was used in the postoperative intravenous analgesia. The dezocine group was given dezocine as extra intravenous analgesia while the control group was not. The visual analogue scale(VAS) at rest and active time and Ramsay sedation score were recorded immediately after operation and at 6, 12, 24, 48 hours after operation. The postoperative evacuation time, degree of satisfaction and the situation of adverse reaction were recorded.? Results There were 93 puerperae participated in this research, 47 cases in dezocine group and 46 cases in control group. Compared with control group, the rest time VAS was lower (2.3±1.3 vs 2.9±1.2, P<0.05) at 24 hours after the operation, the evacuation time was shorter ［(22.0±2.9)h vs (23. 6±2. 6)h, P<0.05], and the degree of satisfaction was higher (61.7% vs 34.8%, P<0.05) in dezocine group. There was no significant difference in the incidence of complications between the two groups (21. 3% vs 28. 3%, P>0.05).? Conclusion Using dezocine in the bundle for analgesia after cesarean section could reduce the uterine contraction pain, shorten the evacuation time and improve the satisfaction without extra adverse reactions.
