Summary

This prospective, randomized, single-blinded study compares the postoperative analgesic efficacy of the Pericapsular Nerve Group (PENG) block and Quadratus Lumborum Block (QLB) in hip surgeries under spinal anesthesia. the study focuses on time to first rescue analgesia and total analgesic consumption within the first 48 hours postoperatively in patients over 40 years undergoing elective hip surgery. Ninety patients will be randomized into two groups (PENG or QLB) using a sealed envelope method. The study will assess pain scores, opioid consumption, and side effects, hypothesizing that both blocks provide effective analgesia but seek to identify which offers superior efficacy. Statistical analysis will be performed with SPSS, aiming to contribute valuable insights into analgesic techniques for hip surgeries.

Interventions

PROCEDURE

PENG block with 0.25% bupivacaine.

In the PENG group, patients were placed in the supine position. A convex ultrasound probe was positioned under sterile conditions on the operated side, aligned with the iliac bone below the anterior superior iliac spine (ASIS). The anterior inferior iliac spine (AIIS), iliopubic eminence (IPE), iliopsoas muscle, and its tendon were identified. Using an in-plane technique, a 22G 100-mm peripheral block needle was advanced toward the IPE, targeting the space between the iliopsoas muscle tendon and the IPE. Proper placement was confirmed via hydrodissection. Subsequently, 20 mL of 0.25% bupivacaine was administered slowly, with aspiration performed every 5 mL to avoid intravascular injection. The correct spread of the local anesthetic was verified via ultrasound, confirming elevation of the iliopsoas tendon.

PROCEDURE

anterior quadratus lumborum block

The quadratus lumborum and psoas major muscles, along with the transverse process of the L4 vertebra, were visualized in the midaxillary line using an in-plane technique. A 22G, 100-mm peripheral block needle (Stimuplex® Ultra; B. Braun Melsungen AG, Melsungen, Germany) was advanced into the subfascial plane between the quadratus lumborum and psoas major muscles, and 1-2 mL of 0.9% saline was injected to confirm correct placement via hydrodissection. Following this, 20 mL of 0.25% bupivacaine (Buvasin® 0.5%, VEM, Tekirdağ, Turkey) was injected incrementally, with aspiration performed every 5 mL. Proper spread of the local anesthetic was confirmed by ultrasound visualization of a hypoechoic distribution between the fascial planes.
