Ultrasound-Guided Pericapsular Nerve Group Block for Pain Control After Hip Surgery
Sponsor: Cumhuriyet University
Summary
This study evaluated whether an ultrasound-guided pericapsular nerve group (PENG) block could reduce pain and morphine use during the first 24 hours after hip surgery. A PENG block involves injecting a local anesthetic near nerves that carry pain signals from the hip. The study included 40 adults aged 20-80 years undergoing planned hip surgery under general anesthesia at Cumhuriyet University Hospital. Participants were randomly assigned to two groups of 20. Before surgery, one group received a PENG block with bupivacaine, a local anesthetic. The other group received an injection of normal saline in the same location as a placebo. Participants and the clinicians assessing postoperative outcomes did not know which injection had been given. After surgery, both groups received morphine through a patient-controlled pump. Pain scores, morphine consumption, the need for additional pain medication, and side effects including nausea, vomiting, and constipation were assessed over 24 hours.

Ultrasound-Guided Pericapsular Nerve Group Block with Bupivacaine
A single ultrasound-guided pericapsular nerve group (PENG) block was performed after induction of general anesthesia and before surgical incision. Using an in-plane approach, bupivacaine 1 mg/kg diluted with 0.9% sodium chloride to a total volume of 30 mL was injected between the psoas tendon and the iliopubic eminence.
Ultrasound-Guided Placebo Injection with Normal Saline
A single ultrasound-guided injection of 30 mL of 0.9% sodium chloride was administered at the same anatomical location as the PENG block, between the psoas tendon and the iliopubic eminence, after induction of general anesthesia and before surgical incision.
