Systemic Hypothermia in Acute Cervical Spinal Cord Injury

November 20, 2025 updated by: Allan D. Levi, University of Miami

Systemic Hypothermia in Acute Cervical Spinal Cord Injury - A Prospective, Multi-center Case Controlled Study

This study is a prospective multi-center trial designed to determine the safety profile and efficacy of modest (33ºC) intravascular hypothermia following acute cervical (C1 to C8) Spinal Cord Injury (SCI).

Detailed Description

The purpose of the proposed clinical trial is to demonstrate the safety and efficacy of intravascular hypothermia as part of the early hospital management and treatment for acute cervical SCI. Each year in the US, there are over 11,000 new cases of para- and quadriplegia and 100,000 new cases of partial but permanent neurological losses due to acute SCI. Thus the potential for clinical hypothermia following SCI to improve neurological outcome has significant value. Many patients suffering SCI become permanently dependent on caretakers and become a financial liability to both the family and society. Hypothermia has the potential to improve outcome so that more patients suffering SCI can regain independent motor and sensory function and remain economically productive members of society. The use of modest hypothermia through intravascular cooling may ultimately lead to better care of the patient with acute SCI and may also have more widespread uses in patients presenting with stroke or cardiac arrest. In the long-term, this research may lend support to the use of hypothermia that could in turn save money for the patients, hospitals, the government and society as a whole.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Hypothermia
Intravascular hypothermia will be initiated within 24 hours post-injury and 33 degrees Celsius will be maintained for 48 hours.
To deliver intravascular hypothermia, an Alsius Icy CoolGuard® catheter (US Food and Drug Administration approved, Premarket Notification [510(k), K030421]; Alsius Corporation, Irvine, California) will be inserted through the femoral vein using a sterile technique. Patients will be cooled at a maximum rate (2-2.5 ºC/hr.) until they reach the target temperature (T 33 ºC), which will be maintained for 48 hours, and then re-warmed at 0.1 ºC/hr. until normothermia (T 37ºC) is achieved.
No Intervention: Control
Standard of care medical treatment, specific to each individual.
