Efficacy of Intermittent Superficial Parasternal Intercostal Plane Block on Postoperative Pain Control in Patients Undergoing Cardiac Surgery With Median Sternotomy - EPOCH Randomized Clinical Trial
In Brief
A clinical study evaluating Intermittent Superficial Parasternal Intercostal Plane Block - Experimental and Intermittent Superficial Parasternal Intercostal Plane Block - Placebo for Post-operative Pain and 5 related conditions. Completed, enrolled 340 participants across 4 sites.
Detailed Summary
The goal of this clinical trial is to assess whether the use of intermittent superficial parasternal intercostal plane blocks reduces opioid usage in patients undergoing cardiac surgery with median sternotomy. Participants randomized to the intervention group will receive the blocks with 0.2% ropivacaine administered via catheters placed in the superficial parasternal intercostal plane bilaterally under ultrasound guidance. Researchers will compare this group with a control group given 0.9% saline through similarly placed catheters. The primary outcome will be cumulative postoperative opioid use (measured as Milligram Morphine Equivalent (MME)) up to 72 hours following catheter insertion.

Timeline
Interventions
Catheter insertion will be performed by an anesthesiologist with regional block training immediately following skin closure in the operating room. Catheters will be inserted under ultrasound guidance, in a sterile fashion, with a high-frequency linear transducer which will be placed 1 cm lateral to the sternal border in the longitudinal plane in order to view the T4-T5 intercostal space. A Tuohy needle will be used to enter the superficial parasternal intercostal plane, with saline being injected to help visualize the plane between the pectoralis major and intercostal muscles. Subsequently, the catheters will be advanced into the plane, and secured on the skin. Following initial bolus after catheter placement (20 mL 0.2% ropivacaine), intermittent boluses of 5 mL 0.2% ropivacaine will be delivered via catheters for 48 hours post-catheter insertion per side every 3-4 hours. There will be a basal infusion rate of 0.1-1mL/hr per side.
