M-Tapa Block for Laparoscopic Inguinal Hernia Repair Surgery

Ultrasound Guided M-Tapa Block for Postoperative Analgesia Management in Patients Underwent Laparoscopic Inguinal Hernia Repair Surgery

Modified Perichondral Approach Thoracoabdominal Nerve (M-TAPA) block is a novel block that provides effective analgesia of the anterior and lateral thoracoabdominal walls during laparoscopic surgery, in which local anesthetic is applied only to the lower side of the perichondral surface. M-TAPA block is a good alternative for analgesia of the upper dermatome levels and the abdominal lateral wall, and may be an opioid-sparing strategy with satisfactory quality improvement in patients undergoing laparoscopic surgery.

M-TAPA block provides analgesia at the level of T5-T11 in the abdominal region. Sonoanatomy is easy to visualize and the spread of local anesthetic can be easily seen. Analgesia occurs in several dermatomes thanks to the cephalocaudal spread of the local anesthetic solution. There are studies in the literature investigating the effectiveness of M-TAPA block for post-operative pain management in several abdominal surgeries.

Detailed Description

Modified Perichondral Approach Thoracoabdominal Nerve (M-TAPA) block is a novel block that provides effective analgesia of the anterior and lateral thoracoabdominal walls during laparoscopic surgery, in which local anesthetic is applied only to the lower side of the perichondral surface. M-TAPA block is a good alternative for analgesia of the upper dermatome levels and the abdominal lateral wall, and may be an opioid-sparing strategy with satisfactory quality improvement in patients undergoing laparoscopic surgery.

M-TAPA block provides analgesia at the level of T5-T11 in the abdominal region. Sonoanatomy is easy to visualize and the spread of local anesthetic can be easily seen. Analgesia occurs in several dermatomes thanks to the cephalocaudal spread of the local anesthetic solution. There are studies in the literature investigating the effectiveness of M-TAPA block for post-operative pain management in several abdominal surgeries.

In this study, we aimed to evaluate the effectiveness of M-TAPA block for postoperative analgesia management after laparoscopic inguinal hernia repair surgery. Our primary aim is to compare the postoperative pain scores (NRS), and our secondary aim is to compare the postoperative rescue analgesic use and postoperative opioid consumption, and the side effects (allergic reaction, nausea, vomiting) associated with opioid use.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
ACTIVE_COMPARATOR: Group M = M-TAPA group; Patients will be administered ibuprofen 400 mgr IV every 8 hours in the postoperative period. Postoperative patient evaluation will be performed by a pain nurse blinded to the procedure. 100 mg tramadol will be performed for rescue analgesia.	Drug: M TAPA block; Under aseptic conditions, a high frequency linear probe will be placed on the costochondral angle in the sagittal plane. Then the probe will be slightly angled deeply to visualize the lower view of the perichondrium. We will perform M-TAPA with totally 40 ml (20 ml for each side) of %0,25 bupivacaine.
NO_INTERVENTION: Group C = Control group; Patients will be administered ibuprofen 400 mgr IV every 8 hours in the postoperative period. Postoperative patient evaluation will be performed by a pain nurse blinded to the procedure. Wound local anesthetic infiltration will be applied to the patients in the control group. 100 mg tramadol will be performed for rescue analgesia.
