Abstract：Objective To compare analgesia effects between local infiltration analgesia and bilateral ultrasound-guided TAP block after cesarean section. Methods A total of 60 parturients scheduled for elective cesarean section in Zhongnan Hospital of Wuhan University from August to December 2016 were selected as research subjects. They were randomly divided into two groups using a random number table: local infiltration analgesia group (group I) and transversus abdominis plane block group (group T), with 30 cases in each group. All parturients underwent cesarean delivery under combined spinal and epidural anesthesia. In the group I, 0.25% Ropivacaine 20 mL was given to the abdominal incision layer in each side for infiltration analgesia before the abdomen was closed; in the group T, parturients received 0.25% Ropivacaine 20 mL bilaterally in the TAP block under the guidance of ultrasound. A Sulfentanil patient-controlled intravenous analgesia pump was used for all patients at the end of surgery. The VAS scores, the number of pressing times of the analgesic pump, the incidence of side effects (nausea and vomiting and urinary retention) and patients′ satisfaction were recorded. Results There was no significant difference in VAS scores between the two groups (P > 0.05). Compared with group I, the number of pressing times was less and patient satisfaction was higher in group T (P ＜ 0.05). The incidence of postoperative adverse reactions in group T was lower than that in group I (P < 0.05). Conclusion Compared with the incision local infiltration analgesia, ultrasound-guided TAP block is helpful in improving the effect of analgesia after cesarean section, it reduces the dosage of intravenous analgesic and the occurrence of adverse reactions related to analgesia, increases patients′ satisfaction.
