M-Tapa Block and Transversus Abdominal Plane Block for Postoperative Analgesia in Unilateral Open Inguinal Hernia Repair Surgery (pain)

Comparison of Patient Satisfaction Survey and Pain Follow-up in Patients Who Underwent M-Tapa Block and Transversus Abdominal Plane Block for Postoperative Analgesia in Unilateral Open Inguinal Hernia Repair Surgery

Patients will be called to the operating room one hour before surgery and no premedication will be applied before coming to the operating room. Patients in both groups who are taken to the block room will be administered 1-2 mg iv midazolam for sedation. M TAPA block will be applied for the surgical procedure. After aseptic conditions are provided, the high-frequency linear US probe will be covered with a sterile sheath. The US probe will be placed in the saggital plane at the costochondral angle where the midclavicular line intersects the costal cartilage. 5 ml of saline will be injected using the in-plane technique using a 22G 100 mm block needle and the block location will be verified. After the block location is verified, a total of 20 ml of 0.25% bupivacaine will be injected unilaterally and the procedure will be terminated. After aseptic conditions are provided, the high-frequency linear US probe will be covered with a sterile sheath. In TAP block, the block needle will be advanced to the fascial plane between the internal oblique and transversus abdominis muscles with the in-plane technique and the procedure will be completed by injecting 5 ml 20 ml 0.25% bupivacaine unilaterally. The same analgesia protocol will be applied to both groups intraoperatively and postoperatively, and a survey will be conducted on the patients at the 24th hour postoperatively.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Group T; The block needle will be advanced to the fascial plane between the internal oblique and transversus abdominis muscles by placing the USG transversely on the mid-axillary line between the iliac crest and subcostal planes. 5 ml saline will be injected and the block location will be confirmed. After the block location is confirmed, a total of 20 ml of 0.25% bupivacaine will be injected unilaterally and the procedure will be completed.	Procedure: TAP Block Group; 20 ml of 0.25% bupivacaine
Active Comparator: Group M; Using the in-plane technique, the probe will be pushed slightly to visualize the lower part of the costochondral angle at the central level, the block needle will be advanced in the caudal-cranio direction, 5 ml of saline will be injected into the layer between the transverse abdominal muscle and the lower plane of the costal cartilage via a 22G 100 mm block needle and the block location will be confirmed. After the block location is confirmed, a total of 20 ml of 0.25% bupivacaine will be injected unilaterally and the procedure will be completed.	Procedure: M TAPA block; 20 ml of 0.25% bupivacaine

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
pain score	Patients' pain scores will be evaluated	The primary aim of our study was to compare VAS scores at 1, 2, 4, 8, 12, and 24 hours postoperatively and to evaluate the level of comfort.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The QoR-15 Patient Questionnaire, a 40-question global recovery rating system with a Turkish variant	To compare patient satisfaction survey and pain monitoring in patients who underwent M-Tapa Block and Transversus Abdominal Plane block for postoperative analgesia in unilateral open inguinal hernia repair surgery and to suggest a more effective method.	24 hours following surgery.
