Percutaneous Intercostal Cryoneuromodulation Onset Timing.

Condition(s) studied

Investigational drug(s) / intervention(s)

Physical examination of chest skin: soft touch and thermal (cold and warm) examination

Study summary

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.

Eligibility

Primary outcome measure(s)

• thermal sensitivity — one week (median)
  Chest skin thermal sensitivity will be assessed through a "thermofeel" metal instrument set at two different temperatures: 15°C for cold sensation and 40°C for warm sensation. At least 4 different chest zones will be tested to discriminate potential differences. As a validated instument for chest skin thermal assessment does not exist, we will report only qualitative results, as "normal" "impaired" or "absent" sensitivity.
