Purpose of trial
The purpose of this study is to see if a nerve block called paravertebral block, done before the surgery, works well for improving pain control and overall satisfaction after heart surgery.
As a background, paravertebral blocks are widely used in anesthesia for pain control after thoracic and breast surgery. This block has been safely used in patients undergoing heart surgery and found to be anecdotally useful. We want to formally test if this nerve block compared to no nerve block can help patients to recover after cardiac surgery.
Pain after cardiac surgery can be severe in the first 2 days. Classically we use opioids/narcotics to treat pain but it can be associated with nausea, vomiting, delirium, sedation and constipation. Nerve blocks have the potential to provide better pain relief with improved side effect profile.
Patients will be randomized to get the paravertebral block or a sham block, where we inject salt water into their back muscle. It is a randomized and blinded controlled trial.
