Clinical study of ultrasound-guided transversus abdominis plane block for analgesia after cesarean section.

BACKGROUND

Patient-controlled intravenous analgesia (PCIA) and patient-controlled epidural analgesia are 2 common methods of maintaining analgesia after cesarean section. In recent years, transversus abdominis plane block (TAPB) has been gradually applied clinically to reduce opioid analgesics and has achieved good results. Therefore, we performed this study to compare the efficacy and side effects of TAPB and PCIA in analgesia after cesarean section.

METHODS

One hundred patients who underwent cesarean section were randomly classified into 2 groups. Following surgery, one group underwent ultrasound-guided TAPB and the other group underwent PCIA. Pain intensity according to the visual analog scale (VAS; 0 for no pain and 10 for severe intolerable pain) was assessed at 2, 4, 6, 8, 12, and 24-hour postsurgery in both groups. The postoperative complication rate and patient satisfaction were also measured.

RESULTS

No significant differences were found in the VAS scores between the groups (P > .05). However, the incidence of postoperative complications in the TAPB group was significantly lower than that in the PCIA group (P < .05). Furthermore, patient satisfaction in the TAPB group was significantly higher than that in the PCIA group (P < .05).

CONCLUSION

This study demonstrated that ultrasound-guided TAPB can achieve the same analgesic effect as PCIA after cesarean section but with even higher patient satisfaction.
