Transversalis Fascia Plane Block Versus Surgical Wound Infiltration for Postoperative Analgesia in Open Inguinal Hernia Repair

The purpose of this clinical trial is to evaluate whether two different analgesic techniques - ultrasound-guided Transversalis Fascia Plane Block (TFPB) and surgical wound infiltration - can improve postoperative pain control in adult patients undergoing open inguinal hernia repair. The key questions that this study aims to answer are: Does TFPB reduce total intravenous opioid consumption within the first 24 postoperative hours compared with wound infiltration? Does TFPB improve postoperative pain scores at rest and during movement compared with wound infiltration? Does TFPB improve patient satisfaction, reduce the need for rescue analgesics, and enhance overall postoperative recovery quality? If there is a comparison group: The investigators will compare the effects of TFPB with wound infiltration to determine whether either technique provides superior postoperative analgesia and reduces opioid requirements. Participants will be asked to: Undergo open inguinal hernia repair under spinal anesthesia. Be randomly assigned to one of two groups: TFPB Group: Receive an ultrasound-guided transversalis fascia plane block with local anesthetic. Wound Infiltration Group: Receive local anesthetic infiltration performed by the surgeon along the incision line. Postoperatively: Report pain scores at defined intervals. Receive standardized IV analgesia with documentation of opioid consumption. Allow assessment of rescue analgesic requirement. Be monitored for adverse events and recovery outcomes.
