Introduction: Transversus abdominis plane (TAP) block as a regional technique that appeared in anaesthesia literature in 2001, is applied as a segment of multimodal pain regimen in abdominal surgeries like caesarean sections. Ultrasonography (USG)- guided TAP Block provides accurate visualization of underlying structures. Our study aimed to compare the efficacy of ultrasound-guided Transversus Abdominis Plane (TAP) block using 0.25% bupivacaine versus parenteral multimodal analgesia in postoperative caesarean section. Aims: To study __ampersandsignbull; Reduction of the additional Rescue analgesia 24 hours following caesarean section. __ampersandsignbull; Duration of analgesia, patient satisfaction, adverse effects like- PONV and sedation. Methods: A total of 60 patients with American Society of Anesthesiologists (ASA) physical status II and III, aged __ampersandsigngt; 18yrs were posted for elective caesarean section were allocated into two groups (n=30). Group, I received a Bilateral TAP Block with 15ml of 0.25% Bupivacaine on each side. Group II received multimodal analgesia according to the Obstetric department protocol. The intensity of pain by Visual Analogue Pain Scale (VAS) Score was assessed, mean duration of analgesia and mean dose of rescue analgesia were recorded. Results: The Visual Analogue Scale scores at 8, 12 and 24 hours in Group I were 1.1__ampersandsignplusmn;1.47, 0.93__ampersandsignplusmn;1.31 and 0.3__ampersandsignplusmn;0.75 and in group II were 3.67__ampersandsignplusmn;1.06, 4.73__ampersandsignplusmn;0.94 and 5.27__ampersandsignplusmn;0.78, respectively. The mean time to first rescue analgesia was statistically significant in Group I 535.27 __ampersandsignplusmn; 118.542 compared to Group II 186.6 __ampersandsignplusmn; 67.6 min. The mean dose of rescue analgesia required over 24 hours was significantly lower in group I with 17.2__ampersandsignplusmn;10.4mg, whereas in group II 28.9__ampersandsignplusmn;24.2 mg. Conclusion: We conclude TAP block is more effective when performed under ultrasound guidance. It provides effective analgesia with reduced rescue analgesic requirement for 24 hours following surgery, with a prolonged duration of analgesia
