Comparing One-Minute and Two-Minute Cryoanalgesia for Pain Relief After Nuss Surgery to Correct Pectus Excavatum in Teens

What this Trial Is About

Researchers are evaluating the effectiveness of one-minute versus two-minute intercostal nerve cryoanalgesia for managing postoperative pain in patients undergoing the Nuss procedure to correct pectus excavatum, also known as funnel chest. This pilot, randomized, double-blind study aims to validate the research procedure and determine the sample size for a larger study. The trial will analyze early data on pain intensity, opioid use, surgery duration, hospital stay length, and complications. Participants will receive either one-minute or two-minute cryoanalgesia applied bilaterally to the intercostal nerves from thoracic levels 3 to 7 during their corrective surgery. The study compares these two durations of cryoanalgesia to assess which is more effective for pain control after the Nuss procedure. During the one-week follow-up, participants postoperative pain levels will be measured using the Numerical Rating Scale. Researchers will also monitor opioid consumption, surgery duration, hospital stay length, and early complications within 30 days after surgery. The study is expected to conclude in March 2026, with ongoing monitoring of these important recovery outcomes.
