Comparison Of Peri Capsular Nerve Group Block Versus Supra Inguinal Fascia Iliaca Block For Positioning During Spinal Anaesthesia for Hip Surgeries – A Prospective Randomised Double Blinded Study

This prospective, randomized, double-blinded clinical study compares the Pericapsular Nerve Group (PENG) block with the Supra-inguinal Fascia Iliaca (SIFI) block for facilitating patient positioning during spinal anesthesia in hip surgeries. Hip fracture patients often experience severe pain, making spinal positioning difficult; thus, effective pre-spinal analgesia is essential.

A total of 84 adult patients (ASA I–II, aged 18–70 years) undergoing elective or emergency hip surgeries are randomized into two groups

Group P (PENG block) – 20 ml 0.25% levobupivacaine + dexamethasone

Group S (SIFI block) – same drug and volume, different technique

Blocks are performed under ultrasound guidance. After 30 minutes, patients are evaluated for

Primary Outcome

Ease of Spinal Positioning (EOSP) Score (0–3 scale)

Secondary Outcomes

Pain scores (NRS) at rest and on movement

Amount of rescue fentanyl required

Operator (anesthesiologist) satisfaction

Quality and duration of postoperative analgesia

Complications (e.g., nausea, quadriceps weakness)

Patients are then positioned for spinal anesthesia, and postoperative analgesia is monitored for 24 hours.

The study aims to determine which block provides superior analgesia, better positioning comfort, and improved anesthesiologist convenience, potentially enhancing the overall safety and efficiency of spinal anesthesia in hip surgeries.
