Pericapsular Nerve Group Block for Analgesia of Positioning pain during Spinal Anesthesia in Hip Fracture Patients, a Randomized controlled Study

Early surgical fixation is the best analgesic for associated pain[1]. Spinal anesthesia has been favored by many anesthesiologists due to the simplicity of the technique, the better analgesic profile, and the lower incidence of complications like delirium and thromboembolic events[2–4].

However, severe pain, encountered during positioning for spinal anesthesia, can complicate the technique and worsen the patient experience. Different regional blocks were employed to facilitate patient positioning for spinal anesthesia including femoral nerve block (FNB), fascia iliaca compartment block (FICB), and lateral cutaneous nerve block (LCNB)[5–8]. Pericapsular nerve group (PENG) block is a recently regional technique based on blocking the articular branches to the hip joint with a single injection and is utilized for perioperative analgesia in hip surgery[9].
