Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to examine the effectiveness of using the Iovera Smart Time 190, for ultrasound-guided cryoneurolysis, in trauma patients 18-64 years old with rib fractures that are not candidates for surgical stabilization. This will offer patients the benefits of cryoneurolysis of the intercostal nerves, thereby providing short and long term pain control while their ribs heal.

The Iovera Smart Tip 190 is FDA approved for cryoneurolysis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this research study is to examine the effectiveness of using the Iovera Smart Time 190, for minimally invasive ultrasound-guided cryoneurolysis, in trauma patients 18-64 years old with rib fractures that are not candidates for surgical stabilization. This procedure will offer patients the benefits of cryoneurolysis (freezing) of the intercostal nerves, thereby providing short and long term pain control while their ribs heal.

Patients in the intervention arm will receive cryoneurolysis via the Iovera device and patients in the control arm will receive standard of care which typically includes multimodal pain therapy and pulmonary toilet. Short and long term pain relief will be compared among both arms.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

We are proposing a prospective, randomized trial evaluating efficacy of ultrasound-guided cryoneurolysis for pain control after traumatic rib fractures in patients 18-64 years of age.

Eligible patients would be enrolled by the trauma service after consent is obtained.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ultrasound-guided Cryoneurolysis: Group A

Patients who are admitted to the Emergency Department after a traumatic injury. Patients will have rib fractures in any of ribs 3-9. Patients will be 18-64 years of age and will be randomized (1:1) to the ultrasound-guided cryoneurolysis group within 72 hours of admission to the ED.

Intervention is ultrasound-guided cryoneurolysis of intercostal nerves creating lost lasting pain relief. Device used for cryoneurolysis is Iovera Smart tip 190

Group Type EXPERIMENTAL

Cryoneurolysis of Intercostal Nerves

Intervention Type DEVICE

Patients will be offered a minimally invasive intervention procedure for pain control called cryoneurolysis using an ultrasound-guided device called the Iovera Smart Tip 190.

The direct application of cold to the intercostal nerves via Iovera device produces lesions in peripheral nervous tissue to block the pain caused by rib fractures.

This procedure is particularly beneficial for patients who are not candidates for surgical stabilization of their rib fractures.

Application of cryoneurolysis as an analgesic will reduce the amount of narcotics patients might need and instead provide them short- or long-term pain control with minimal risk.

Follow up includes pain surveys administered in Chest Wall clinic or via telephone at 30, 90, 365 days post discharge.

Standard-of-Care : Group B

Patients who are admitted to the Emergency Department after a traumatic injury. Patients will have rib fractures in any of ribs 3-9. Patients will be 18-64 years of age and will be randomized (1:1) to Standard of Care which typically includes multi-modal pain therapy and pulmonary toilet.

Group Type ACTIVE_COMPARATOR

Standard of Care

Intervention Type OTHER

Patients will be provided regular standard of care at the Stanford Hospital with short- or long-term follow-up provided at the Stanford Center for Reconstruction after Chest Wall Injury.

Standard of care for patients with rib fractures that are not eligible for surgical stabilization includes multi-modal pain therapy and pulmonary toilet.

Follow up includes pain surveys administered in Chest Wall clinic or via telephone at 30, 90, 365 days post discharge.
