Butorphanol intravenous analgesia combined with transversal abdominis plane block in postoperative analgesia after cesarean section / 重庆医学

ABSTRACT

J Objective To investigate the efficacy of butorphanol intravenous analgesia combined with transversus abdominal plane block in postoperative analgesia after cesarean section.Methods A total of 120 cases of cesarean section performed in Jinjiang Hospital from August 2021 to January 2022 were selected for the study.The cases were divided into three groups,according to the different methods of maternal postopera-tive analgesia,the group A was treated with intravenous analgesia(100 mL normal saline containing 3 μg/kg butorphanol+25 mg dolasetron,2 mL/h,continuous analgesia for 48 h);the group B received intravenous analgesia(100 mL normal saline containing 3 pg/kg butorphanol+25 mg dolasetron,2 mL/h,continuous an-algesia for 48 h)combined with transverse abdominal plane block(0.5％ropivacaine given bilaterally on each side).2 μg/kg butorphanol+25 mg dolasetron,2 mL/h,continuous analgesia for 48 h)combined with trans-versus abdominis plane block(10 mL of 0.5％ropivacaine was given bilaterally),and intravenous analgesia in the group C(100 mL of saline containing 2 pg/kg butorphanol+25 mg dolasetron,2 mL/h,continuous anal-gesia for 48 h)combined with transversus abdominis plane block(0.5％ropivacaine 10 mL was given bilater-ally),and the three groups were compared in terms of the VAS scores of postoperative analgesia at 4,8,12,24 and 48 h,the occurrence of the incidence of adverse reactions,such as dizziness,drowsiness,nausea,and vomi-ting,and the satisfaction with the analgesia.satisfaction of analgesia.Results Comparison of analgesic effect between groups,the VAS of group B and group C were significantly lower than those of group A at 4,8 and 12 h after surgery(P＜0.05),but there was no significant difference between group B and group C in pain scores(P＞0.05),and postoperative 24,48 h pain scores of the three groups are not statistically different(P＞0.05).In terms of the incidence of adverse reactions such as dizziness,drowsiness,nausea and vomiting,there was no significant difference in the incidence of adverse reactions between the group A and the group B,and they were all higher than that of the group C.Satisfaction with analgesia at 4,8,12,24,48 h after surgery:group C＞group B＞group A.Conclusion The multi-mode analgesia program of butorphanol intravenous an-algesia combined with transversal abdominis plane block can be safely and effectively used for postoperative analgesia after cesarean section,and appropriate reduction of butorphanol dosage when combined can alleviate the adverse reactions brought by opioids,thus improving the satisfaction of patients with postoperative analge-sia.
