Abstract:
Objective To observe the effect of postoperative analgesia for cesarean section with a new approach to transversus abdominis plane block.Methods 40 ASA physical status Ⅰ to Ⅱ patients undergoing cesarean section firstly were rucruited.All the patients were randomly divided into the two groups,20 cases in each group.A standard subarachnoid block was used.Group A:TAP block was performed at the end of surgery by piercing the transversus abdominis muscle from inside the abdominal wall at the midaxillary line at the level of the umbilicus with a 22-gauge blunt needle.The patients were assigned to receive 20mL of 0.298％ ropivacaine on each side of the abdominal wall.Group B:the patients were also assigned to receive normal saline.Sufentanil was used for postoperative analgesia by PICA.Each patient was assessed at 2,4,8,24 hours postoperatively using a visual analog scale,the dosage of analgesic drug and the adverse reactions.Results Compared with group B,group A had significantly lower pain scores at 2,4 hours using a visual analog scale (P ＜ 0.05) and there were no significant differernces in 8,24 hours(P ＞ 0.05).The cumulative sufentanil requirement of group A was also significantly lower at all time points (P ＜ 0.01).The incidence of sedation of the two groups were also significant differernces,eg.nausea and vomiting (15％/25％),itchy skin(5％/20％),dizziness(0/10％) (P ＜ 0.05).Conclusion This new approach to transversus abdominis plane block provides effective postoperative analgesia after cesarean section.
