Abstract

An evaluation was made of analgesic efficacy and side effects of ultrasound - guided transversus abdominis plane (TAP block) in women undergoing intubation anesthesia for caesarean section in Hanoi Obstetrics and Gynecology hospital, Vietnam. This was a comparative randomized clinical trial; 120 women underwent caesarean delivery under general anesthesia: patients received a TAP block in both sides (TAPB group, n = 60) or no TAP block (control group, n = 60). Both groups received analgesia with intravenous morphine controlled by the woman during 72 hours after surgery. Pain scores at rest and activity, morphine consumption during 72 hours, side effects (sedation, nausea and vomiting) and satisfaction of women were recorded. The time to first analgesic request in the TAP block group was 817 ± 311 minutes (13.6 ± 5.2 hours). There was a reduction of VAS (visual analog scale) scores after surgery in the TAP block group. The total morphine consumption was reduced more than 62% in the TAPB group (16.03 mg) compared with the Control group (41.65 mg). The incidence of PONV (postoperative nausea and vomiting) (5%) and sedation (3.3%) was reduced in patients who had a TAP blockade. The patient satisfaction with regards to pain relief was greater in the TAPB group (95 vs 65%). There were no complications attributable to the TAP block. Ultrasound-guided TAP block provided a better analgesic effect after caesarean section, reduced morphine consumption during 72 hours, and reduced side effects.
