Abstract

Background: Preoperative education and perioperative pain management planning are crucial for the efficient treatment of postoperative pain. In order to complete a field block, the transversus abdominis plane (TAP) block was originally used as a landmark-guided technique. Numerous drugs, including nitroglycerin, clonidine, and scopolamine, have been confirmed to be administered transdermally. Objective: The efficacy of ultrasonic guided Transversus Abdominis Plane (TAP) block verse fentanyl patches in post-cesarean section pain management throughout a 24-hour period. Material and methods: 100 pregnant women who were planned for an elective caesarean birth under spinal anaesthesia were enrolled in a prospective cohort study. Following surgery, subjects were divided into two equal groups at random and given patches containing 25 g/h of fentanyl (TFPs). Following surgery, 20 mL of 0.25 percent bupivacaine was administered to the second group as a transversus abdominis plane (TAP) block. Results: In terms of VAS score and pain threshold, statistical analysis of present results revealed that pain was lower with TFPs versus TAP block at 2, 4, 6, and 24 hours. When TFPs were used instead of TAP block, hypotension was much more common. Conclusions: In women undergoing cesarean section, transdermal fentanyl patches were more effective than transversus abdominis plane block regarding postoperative analgesia.
