Caesarean delivery is one of the most commonly performed surgical procedures. The postoperative pain associated with it causes significant reduction in the functional quality of the postpartum mother especially on the day of the procedure. The optimum form of postoperative analgesia is not known, but many procedures are carried out under spinal anaesthesia and patients typically receive spinal opioids, systemic opioids as components of multimodal analgesia in the postoperative period. However, long acting opioids, whether given via the spinal or systemic route, are frequently associated with adverse effects such as nausea, pruritus, sedation and occasionally respiratory depression. Thus knowledge about the alternative (non-opioid) analgesia especially regional techniques is important.

The regional techniques like epidural and TAP blocks have been found to provide effective postoperative analgesia in cesarean deliveries. ESP block is a novel technique which has found its applicability in many truncal and hip surgeries. Also, it is believed that this technique is technically less demanding as compared to other techniques described above
