Study of Pericapsular Nerve Group Block Before Total Hip Arthroplasty Surgery to Reduce Pain and Speed Recovery

What this Trial Is About

Researchers are evaluating the effects of the Pericapsular Nerve Group PENG block on patients undergoing Total Hip Arthroplasty THA surgery with spinal anesthesia. The study aims to determine whether the PENG block reduces postoperative pain scores, lowers the need for opioid painkillers, and enables earlier mobilization compared to not using the block. It also investigates the impact of the block on hip joint function, length of hospital stay, perioperative blood pressure and heart rate, and any side effects after surgery. In this randomized controlled trial, 60 patients aged 40 to 85 years undergoing THA surgery were divided into two groups one received the PENG block before surgery, where 20 ml of 0.5% bupivacaine was injected between specific tissues using ultrasound guidance, and the other group did not receive the block. Both groups had spinal anesthesia. Additionally, all patients received multimodal pain control, including local infiltration of bupivacaine and lidocaine at the surgical site, and postoperative pain management with tramadol via a patient-controlled analgesia device plus intravenous paracetamol. Participants are monitored for postoperative pain at multiple time points up to 48 hours after surgery, time taken to begin moving after surgery, hip joint openness at 24 hours, and total opioid use in 48 hours. Side effects related to the PENG block and perioperative blood pressure and heart rate at specific times are also recorded. The study tracks the length of hospital stay. This structured approach helps researchers assess recovery quality and safety during the early postoperative period.
