Brief 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.

Interventions

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

PROCEDUREQIPB

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

Design outcomes

Primary

MeasureTime frameDescription
Pain ScoreUp to 24 hoursPain 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.

Secondary

MeasureTime frameDescription
Patient Satisfaction24th hourQuality of recovery-15 (QoR-15) score was used as the satisfaction score. The patient-reported Turkish QoR-15 score includes 15 questions that evaluate the patient's postoperative recovery. The QoR-15 score is grouped under two groups, A and B. A high QoR-15 score, a score between 0 (poor) and 10 (excellent) for each item, and a total score of 150 indicate better quality of recovery.
