Comparing Dexmedetomidine Added to Bupivacaine Versus Bupivacaine Alone in Ultrasound-Guided Pericapsular Nerve Group Block for Laparoscopic Shoulder Surgery A Randomized Controlled Trial

What this Trial Is About

This research aims to compare the effect of adding dexmedetomidine to bupivacaine in an ultrasound-guided Pericapsular nerve group block PENG for patients undergoing laparoscopic shoulder surgeries. The study addresses the common problem of significant pain after shoulder surgery, which can affect recovery and rehabilitation. Interscalene nerve blocks are effective for shoulder pain but carry risks such as breathing issues. The PENG block, effective in hip surgeries, is being studied here for shoulder surgery pain relief, with dexmedetomidine added for potential enhanced analgesic effects. Participants will be randomly assigned to one of two groups one receiving the PENG block with bupivacaine alone, and the other receiving the PENG block with bupivacaine plus dexmedetomidine. The block is performed using ultrasound guidance and involves injecting the drug near specific shoulder muscles before general anesthesia is administered. The study monitors patients during surgery and recovery, with careful management of anesthesia and vital signs. Participants will be assessed for pain using a visual analogue scale at various intervals up to 24 hours after surgery. Postoperative opioid use will be tracked, and vital signs monitored to note any adverse effects such as low blood pressure or slow heart rate. The primary outcome is the time until first rescue analgesia is needed in the first 24 hours after surgery. The total opioid consumption in the same period is also measured. Participation includes preoperative assessments, the nerve block procedure, surgery, and postoperative monitoring.
