Effect of the Modified Surgeon Assisted Bilateral TAP block on time required for first analgesic dose after Cesarean Section under spinal anesthesia: A Randomized, placebo-controlled, double blinded clinical trial

Abstract

cute severe pain after cesarean delivery is frequent. At least 10 to 15% of the women develop chronic pain. Effective postoperative analgesia after cesarean section is important because it enables early ambulation and facilitates breastfeeding. The transversus abdominis plane (TAP) block is a regional analgesic technique that blocks T6–L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries. Various techniques are used for postoperative pain relief after cesarean delivery under spinal anesthesia, including intrathecal and/or systemic opioids, abdominal nerve blocks, and truncal blocks such as the transversus abdominis plane (TAP) block with parenteral analgesics and bilateral erector spinae plane (ESP) block. TAP block has gained popularity as an effective analgesia technique in mothers undergoing cesarean delivery and works by blocking the anterior rami of the spinal nerves of the anterior abdominal wall after spreading of the local anesthetic agent in the neurofascial plane between the internal oblique and transversus abdominis muscle, thereby relieving the pain of cesarean section.
