Abstract To explore the application of transversus abdominal plane block (TABP) combined with patient-controlled intravenous analgesia (PCIA) for postoperative analgesia of women after cesarean section. Methods: 90 women who underwent cesarean section were enrolled and were divided into two groups (45 cases in each group) by random number table method from February 2018 to February 2020. The women in the control group were given PCIA, while the women in the observation group were given TABP combined with PCIA. The score of visual analogue scale (VAS), the situation of analgesic pump used, the sufentanil dosage, the extubation time, the anal exhaust time, the hospitalization time, the values of hemodynamic indexes systolic blood pressure (SBP), the diastolic blood pressure (DBP) value, and heart rate (HR), and the incidence of complications of the women were compared between the two groups. Results: The dynamic VAS scores of the women in the observation group at 4h, 6h, 8h, 24h and 48h after operation were significant lower than those of the women in the control group (P＜0.05), but there was no significant difference in the VAS scores of the women between the two groups (P＞0.05). The duration from operation finished to the first pressure of analgesia pump (12.5±5.1h) of the women in the observation group was significant longer than that of the women in the control group. The number of pressure times of analgesia pump (2.1±0.7 times) and the amount of sufentanil (50.6±6.3 mg) in 24h after surgery of the women in the observation group were significant lower than those of the women in the control group. The anal exhaust time (4.7±1.2d) of the women in the observation group was significant shorter than that of the women in the control group. The values of SBP, DBP and HR before and after extubation of the women in the observation group were significant lower than those of the women in the control group. The complication rate (13.3%) of the women in the observation group was significant lower than that (31.1%) of the women in the control group (all P＜0.05). Conclusion: TABP combined with PCIA for postoperative analgesia after cesarean section has better effectiveness, which can reduce the PCIA dosage, the stabilize hemodynamics, and the promote gastrointestinal peristalsis, with relatively higher safety.
