Abstract: Objective To explore the preventive value of butorphanol in peritoneal traction reaction during cesarean section of scarred uterus.Methods Eighty cases of cesarean section of scar uterus treated from May 2017 to May 2018 were selected as study subjects, and divided into observation group and control group with 40 cases in each group by random number table.The observation group was given butorphanol immediately after delivery, while the control group was not given intravenous adjuvant drugs.The average hemodynamics of the two groups were recorded; pain was evaluated by Visual Analogue Scale (VAS) during uterine suture (T₁), abdominal cavity cleaning (T₂), peritoneal suture (T₃), and uterine compression (T₄); the incidence rate of traction reaction and adverse drug reactions of the two groups were also recorded.Results The HR, MSP, and SPO₂ in the observation group were significantly lower than those in the control group (P<0.05); the VAS score in the observation group was significantly lower than that in the control group at each time point (P<0.05); the incidence rate of traction reaction in the observation group (10%) was also significantly lower than that in the control group (55%) (P<0.05).The incidence rate of adverse reactions was 2.5% in the observation group, and there was no adverse drug reactions in the control group, with no significant difference between the two groups (P>0.05).Conclusion Butorphanol can stabilize the hemodynamics of cesarean section of scarred uterus, alleviate maternal pain, and improve traction reaction; it is safe to use butorphanol.
