Objective To investigate the optimal dose of butorphanol in the treatment of shivering in patients underwent cesarean section. Methods A total of 150 women with cesarean section in our hospital from October 2019 to November 2020 were selected as the research objects, and were divided into group A, group B and group C according to random number table method, with 50 cases in each group. Group A was given 0.01 mg/kg butorphanol intravenously, group B was given 0.02 mg/kg, and group C was given 0.03 mg/kg. Clinical efficacy, hemodynamics, sedation (Ramesay) scores, adverse drug reactions (ADR) and neonatal Apgar scores were compared among the three groups. Results There were no significant differences in effective rate, hemodynamics, Ramesay scores at T₁ and T₂ time periods and Apgar scores of neonates at 1 min, 5 min and 10 min among the three groups (P>0.05). The incidence of ADR in group C was higher than that in group B and A (P<0.05). Ramesay score at time of T₃ of group C was lower than group B and group A (P<0.05). Conclusion The 0.02 mg/kg dose of butorphanol in the treatment of perioperative shivering in cesarean section was the most ideal dose, perioperative hemodynamics of puerpera was stable, adverse reactions were mild, and there was no obvious influence on neonates.

Objective To retrospectively analyze the medical records of patients undergoing cesarean section in our hospital in recent 9 years, and explore the risk factors of incision fat liquefaction after operation. Methods 1 018 patients undergoing cesarean section in our hospital from January 2011 to August 2019 were divided into two groups: incision fat liquefaction group and grade A healing group. The differences between the two groups were compared and the risk factors were analyzed. Results Among 1 018 parturients, 34 had incision fat liquefaction, and the incidence was 3.34% (34/1018). Univariate analysis showed that diabetes mellitus, overweight body mass index and incision length of more than 7 cm were risk factors for incision fat liquefaction after operation, and the difference was statistically significant. Multivariate logistic regression analysis showed that diabetes mellitus, overweight body mass index and incision length over 7 cm were independent risk factors for incision fat liquefaction. Conclusion The incision fat liquefaction rate is higher in patients undergoing cesarean section. Controlling blood sugar level, body mass index during pregnancy and shortening the length of incision during perioperative period may effectively reduce the incidence of incision fat liquefaction.

Objective To compare the clinical effects of different concentrations of ropivacaine for postoperative analgesia after cesarean section. Methods 300 cases of pregnant women undergoing cesarean section in our hospital from March 2015 to March 2016 were selected and were randomly divided into group A, group B and group C with 100 cases in each group. The patients in group A were given 0.15% ropivacaine 1.5 mg/kg, 0.20% ropivacaine 1.5 mg/kg in group B and 0.25% ropivacaine 1.5 mg/kg in group C, and at the same time all the pregnant women were given analgesic pump assisting analgesia. The pain visual analogue scales (VAS) of the pregnant women were recorded at 6 hours, 12 hours, 24 hours and 36 hours after cesarean section and the number of times of analgesia pressing pump were also recorded. The satisfaction degree of analgesic effect and the TAP occurrence of adverse reactions of the patients were also recorded. Results The VAS scores of group B and group C were lower than that of group A(P<0.05). 24 hours after cesarean section, the VAS score of group C was lower than that of group B (P<0.05). Compared with group B and C, the number of times of analgesia pressing pump in group A were more but the analgesic effect of satisfaction was lower (P<0.05), and at the same time the number of times of analgesia pressing pump in group B were more than those in group C (P<0.05). No adverse reactions were found in the three groups. Conclusion The treatment of using of 0.25% of ropivacaine for muscle block for postoperative analgesia after cesarean section is effective and safe, which may be widely used in clinical practice.
