Ultrasound Guided Transversus Abdominis Plane Block Combined with Transversalis Fascia Plane Block Versus Ultrasound Guided Transversus Abdominis Plane Block Alone for Pain Relief in Patients Undergoing Laparotomy

Background: A substantial component of the pain experienced by patients after abdominal surgery is derived from the abdominal wall incision. An approach to provide post-operative analgesia after abdominal incision is to block the sensory nerve supply to the anterior abdominal wall. Subjects and Methods: Twenty eight patients undergoing laparotomy were randomized into two equal groups. Those in Group A received combined TAPB TFPB and those in Group B received TAPB alone. Heart rate and blood pressure were obtained intraoperatively. Results: Our study demonstrates that real time ultrasound guided combined TAP with TFP block provides additional benefit to multimodal analgesia more than the real time ultrasound guided TAP block alone in adults undergoing laparotomy with infra-umbilical incision. The patients who received the combined block required less intraoperative as well as postoperative analgesic requirements. Conclusion: Our study demonstrates that real time ultrasound guided combined TAP and TFP block provides additional benefit to multimodal analgesia in adults undergoing laparotomy. The patients who received combined TAP and TFP block required less intraoperative analgesic requirements, as well as postoperative rescue analgesiathan patients who received TAP block alone.
