Ultrasound-Guided Pericapsular Nerve Group Block for Pain Control After Hip Surgery

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.
