Abstract

Objectives: To evaluate the analgesic efficacy and complications of ultrasound-guided transversus abdominis plane block (TAP block) after cesarean section. Methods: Prospective study on 30 pregnant women undergoing ultrasound-guided transversus abdominis plane block using bupivacaine 0.25% at a dose of 1 mg/kg combined with dexamethasone 4 mg on each side. After determining the position between the transverse abdominis and the internal oblique muscle and the needle tip on the ultrasound screen, inject the drug between the two muscle layers and monitor the onset time of analgesia, analgesic efficacy, the rate of success, and complications of technique. Results: Surgeries included 40.9% first cesarean section, 50% second cesarean section, 9.1% third or more cesarean section; the average time of onset of pain relief was 12.7±3.3 minutes, the average time of pain relief was 638.7±91.9 minutes, the average VAS score at rest after 1 hour was 1.08±0.92; after 6 hours was 1.92±0.95; after 12 hours was 3.38±1.04; after 24 hours was 3.92±1.21. All patients did not use fentanyl. The success rate was 100%; no complications of the technique were recorded. Conclusions: Ultrasound-guided transversus abdominis plane block (TAP block) for 30 patients after cesarean section reduced pain well; no other analgesics were recorded, and the success rate was 100%; this is no complication.
