Study Comparing Ultrasound-Guided Serratus Plane Blocks Versus Local Wound Infiltration for Pain Relief After Minimally Invasive Heart Surgery

What this Trial Is About

Researchers are evaluating the pain relief effects of two different methods in patients undergoing minimally invasive cardiac surgery MICS. This study compares a combination of two ultrasound-guided nerve blocksthe serratus anterior plane SAP block and the serratus-intercostal interfascial plane SIP blockwith the traditional local wound infiltration LWI method. The goal is to see which approach better manages pain after surgery, focusing primarily on opioid use and pain scores. Participants are randomly assigned to one of two groups. One group receives the SAP block with 30 mL of 0.25% bupivacaine combined with the SIP block using 10 mL of 0.25% bupivacaine, both given after surgery but before waking up from anesthesia. The other group receives local wound infiltration with 40 mL of 0.25% bupivacaine applied to the surgical and drain sites after surgery. A total of 60 patients will be studied. During the study, patients opioid use will be measured over the first 48 hours after surgery. Pain levels will be recorded at multiple times up to 72 hours after surgery, along with monitoring for opioid-related side effects, any complications from the nerve blocks, and the length of stay in the intensive care unit. These assessments will help determine which pain management method performs better in this surgical setting.
