Summary

Intercostal cryoanalgesia is a technique that allows extensive and prolonged analgesia of the hemithorax. The aim of this study is to demonstrate the efficacy of intercostal cryoanalgesia as an adjunct to a single-injection paravertebral block for the management of acute thoracic pain after VATS lung resection surgery.

Detailed description

VATS lung resection is associated with a high incidence of moderate to severe acute thoracic pain. In the postoperative period, optimal analgesia may facilitate recovery, lead to higher patient satisfaction, and lower postoperative complications. Regional analgesia techniques are usually recommended for VATS, and the paravertebral block is often used. However, the duration of the paravertebral block is short (6 to 24 hours), and prolongation of the effect requires the placement of a paravertebral catheter and local anesthetic infusion into the paravertebral space. At our institution, patients with VATS lung resections are often discharged home 24-48 hours after surgery. Intercostal cryoanalgesia has an onset of about 12 hours, which coincides with the weaning of the single-injection paravertebral block. Analgesia is usually prolonged over several weeks, does not require catheter placement, and is not associated with hemodynamic side effects. These characteristics may allow rapid recovery and safe home discharge after VATS lung resection. The aim of this study is to demonstrate the efficacy of intercostal cryoanalgesia as an adjunct to a single-injection paravertebral block for the management of acute thoracic pain after VATS lung resection surgery.
