Comparison of Postoperative Analgesic Effects of Quadro-iliac Plane Block and Transversus Abdominis Plane Blocks in Inguinal Hernia Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

TAPB: Patients will undergo TAPB procedure using 30 ml of 0.25% bupivacaine under ultrasound guidance.

QIPB: Patients will undergo QIPB procedure using 30 ml of 0.25% bupivacaine under ultrasound guidance.

Study summary

Inguinal hernia repair is one of the most commonly performed surgical procedures worldwide. Despite being classified as a minor surgical intervention, moderate to severe postoperative pain is reported in approximately 60% of patients. In a subset of these patients, acute postoperative pain may persist and evolve into chronic post-surgical inguinal pain, significantly affecting quality of life.

In recent years, beyond the use of systemic intravenous analgesics, ultrasound-guided fascial plane blocks have been increasingly incorporated into multimodal analgesia protocols with the aim of reducing postoperative opioid consumption and improving pain control. However, the current literature does not provide definitive evidence regarding the superiority of one block technique over another in this surgical population.

The primary objective of the present study is to compare the analgesic efficacy of the Quadro-iliac Plane Block (QIPB) and the transversus abdominis plane block (TAPB) in patients undergoing inguinal hernia repair.

Eligibility

Primary outcome measure(s)

• Pain Score — Up to 24 hours
  Pain will be assessed using a visual analog scale from 0 mm (no pain) to 100 mm (worst pain) at rest and when coughing. Pain assessment will be made at 0, 1, 6, 12, 18, and 24 hours after surgery.
