Overview
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.
Interventions
- Procedure TAPB
Patients will undergo TAPB procedure using 30 ml of 0.25% bupivacaine under ultrasound guidance. - Procedure QIPB
Patients will undergo QIPB procedure using 30 ml of 0.25% bupivacaine under ultrasound guidance.
Primary outcome measures
- Pain Score [Time frame: Up to 24 hours]
Secondary outcome measures (1)
- Patient Satisfaction [Time frame: 24th hour]
