To evaluate the analgesic effect of transverse abdominal plane (TAP) block in obese women undergoing cesarean section.

A total of 50 obese women who underwent cesarean section at Yangjiang People’s Hospital from January 2019 to June 2020 were selected and randomly divided into treatment group and control group, 25 cases in each group. The treatment group was treated with ultrasound-guided lower transversus abdominis plane block before operation, and 0.375% ropivacaine 20 ml was injected on each side. The control group was given conventional treatment. Comparing the doses of sufentanil given by patient-controlled epidural analgesia at 24 h and 48 h after operation between the two groups of parturients, recording the time of initial supplementary analgesia, and comparing the pain scores, Ramsay sedation and BCS comfort of the two groups at different time points after surgery Score, record the adverse reactions of the two groups.

The amount of sufentanil in 24 h and 48 h in patient-controlled epidural analgesia in the treatment group was significantly less than that in the control group, and the difference was statistically significant (P<0.01); The first additional analgesia time in the treatment group was significantly longer than that in the control group (P<0.01), and 4 h, 8 h, 12 h, 24 h and 48h postoperative pain VAS scores of the treatment group were significantly lower than those of the control group (P<0.05). The BCS comfort scores of the treatment group at 12 h and 24 h after surgery were significantly higher than those of the control group, and the difference was statistically significant (P<0.001). There was no statistically significant difference in Ramsay sedation and PONV scores between the two groups (P>0.05).

TAP block has a good analgesic effect in obese women undergoing cesarean section, can significantly improve the postoperative comfort of the women, and has good safety.
