Background: Transverses abdominis plane [TAP] block through ultrasound is a unique strategy to block abdominal wall neuro afferents for postoperative analgesia
Aim of the work: The purpose of our research was to assess efficacy and safety of USG-TAP block for treating post-operative pain following cesarean birth.  
Patients and methods: This single-centered investigation was carried out at Al-Azhar University Hospital's Obstetrics & Gynecology Department at New Damietta. This research included 90 pregnant women who had elective cesarean deliveries. The patients were separated into three groups: group 1 [n = 30 women] got TAP block, group 2 [n = 30 women] received saline injection, and group 3 [n = 30 women] neither TAP block or saline injection.
Results: When comparing Visual Analogue Scale [VAS] of pain between three groups studied, our findings revealed that VAS was lower among Group 1 in significant way in comparison with Group 2 in all studied time intervals except baseline, while Group 3 had a higher VAS value.
Conclusion: USG-TAP block had effective analgesic effect post cs under spinal anesthesia. This could improves satisfaction of patient in safe and effective way.
