No results posted yet for this study

Summary

This study will be conducted to evaluate efficacy of ultrasound guided modified thoracoabdominal nerves block via a new perichondrial approach (M-TAPA) for postoperative analgesia in major abdominal surgeries in comparison to subcostal transverse abdominis plane (SCTAP) block.

It is hypothesized that M-TAPA block will be advantageous to SCTAP block as a promising effective alternative for analgesia for major abdominal surgeries with fewer side effects.

Conditions

  • Abdominal Surgery

Interventions

PROCEDURE

M-TAPA block

A high-frequency linear ultrasound probe will be used, probe will be placed on the costochondral angle in the sagittal plane and angled deeply to view the lower aspect of the chondrium in the midline, then using in-plane approach, a 22 Gauge Tuohy needle will be introduced into the lower aspect of the chondrium. The same procedure will be repeated on the contralateral side.

PROCEDURE

SCTAP block

A high-frequency linear ultrasound probe will be placed obliquely on the upper abdominal wall, along the subcostal margin near the midline. After identifying the rectus abdominis muscle, the ultrasound probe will be gradually moved laterally along the subcostal margin until the transversus abdominis muscle will be identified lying posterior to the rectus muscle, then using in-plane approach, a 22 Gauge Tuohy needle will be introduced medially and directed towards the transversus abdominis plane until its tip reaches the fascia between the rectus abdominis and the transverse abdominis muscles on entering the neurofascial plane. The same procedure will be repeated on the contralateral side.

DRUG

Bupivacaine Hydrochloride

20 ml 0.25% bupivacaine will be injected after the negative aspiration test.
