Percutaneous Intercostal Cryoneuromodulation Onset Timing.

How Long Does it Take for Percutaneous Intercostal Cryoneuromodulation to Produce Cryoanalgesia? A Prospective Observational Study.

Percutaneous Intercostal Cryoneurolysis is a promising technique that addresses acute postoperative pain after Nuss procedure for pectus excavatum. However its onset timing has not yet been determined. A physical examination would assess the variation of chest skin sensitivity to soft touch, cold (water at 4°C), and heat (water at 40°C) through days following the cryoneurolysis procedure.

Inclusion Criteria:

• Patients who are undergoing preoperative percutaneous intercostal cryoneurolysis for pectus excavatum surgery

Exclusion Criteria:

• failure to obtain consent
