Heart surgery pain study pulled before it began
NCT ID NCT04788056
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to see if a nerve block called a parasternal subpectoral plane block could reduce pain and the need for opioids after heart surgery. It planned to compare a numbing medicine (bupivacaine) to a saltwater placebo in about 100 adults having elective heart surgery. However, the study was withdrawn before enrolling any participants, so no results are available.
