Rib Fracture Analgesia Using Cryoanalgesia
Completed · Phase 4 · Has a placebo group
Conditions studied: Traumatic Rib Fracture(s)
In brief
Rib fractures are one of the most common injuries in trauma patients. These fractures are associated with significant pain as well as decreased ability to inspire deeply or cough to clear secretions, which together lead to pulmonary complications and a high degree of morbidity and mortality. Peripheral nerve blocks as well as epidural blocks have been used with success to improve pain control in rib fracture patients and have been associated with decreased pulmonary complications and improved outcomes. However, a single-injection nerve block lasts less than 24 hours; and, even a continuous nerve block is generally limited to 3-4 days. The pain from rib fractures usually persists for multiple weeks or months. In contrast to local anesthetic-induced nerve blocks, a prolonged block lasting a few weeks/months may be provided by freezing the nerve using a process called "cryoneurolysis". The goal of this multicenter, randomized, double-masked, sham-controlled, parallel-arm study is to evaluate the potential of cryoanalgesia to decrease pain and improve pulmonary mechanics in patients with rib fractures.
