Summary

This study tests whether a nerve block given before heart surgery can reduce pain and the need for opioid painkillers afterward. About 150 adults having heart surgery will receive either a long-acting or standard form of the numbing drug bupivacaine via ultrasound-guided injection. Researchers will track how much opioid medication patients need in the first five days after surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
bupivacaine (as liposomal or standard injection)
What this could lead to
If it works, this could offer a better way to manage pain after heart surgery, reducing the need for strong opioids.
What could go wrong
This is a small pilot study, so results may not apply to all patients. The nerve block may not provide significant benefit over standard care.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults (18 years-no upper age limit) * Scheduled for mini thoracotomy (i.e. valve repair) or open sternotomy (i.e. bypass graft) at single academic medical center (in and out-patients). Exclusion Criteria: Patients will be excluded if they: * Are currently on pain medication or pain regimen for chronic pain condition * Convert to sternotomy (for thoracotomies) * Require, upon intraoperative discovery and surgeon's decision, the need for an unplanned secondary procedure other than the originally scheduled index operation * Undergo emergent surgery * Are non-English speaking (The majority of the PI's patient population speak English. As a pilot study the investigators cannot afford to enroll non-English speaking subjects due to time, personnel, and financial constraints.) * Mechanical circulatory support (MCS) * Vasoactive medications * Intubated * Active infection * Patients otherwise deemed ineligible for ESP block by the investigators due to safety concerns.
