Systemic hypothermia in acute cervical spinal cord injury: a case-controlled study

Area of Science:

• Neurology
• Neurosurgery
• Critical Care Medicine

Background:

• Systemic hypothermia is a recognized neuroprotective strategy.
• Intravascular hypothermia is being explored for spinal cord injury (SCI) treatment.
• Cervical SCI presents a critical therapeutic challenge.

Purpose of the Study:

• To evaluate the safety and efficacy of intravascular hypothermia in acute cervical SCI.
• To assess neurological outcome and complication rates in treated patients.
• To contribute to the understanding of hypothermia as a neuroprotective intervention.

Main Methods:

• Thirty-five patients with acute cervical SCI underwent intravascular hypothermia (33°C) for 48 hours.
• Neurological function was assessed using the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) scale.
• Local and systemic complications were systematically recorded.

Main Results:

• 43% of patients (15/35) improved by at least one ISNCSCI grade at 10-month follow-up.
• Excluding early converters, 35.5% (11/31) still showed neurological improvement.
• Respiratory complications were similar in retrospective and prospective groups; thromboembolic risk was 14.2%.

Conclusions:

• Modest intravascular hypothermia appears safe and effective for improving neurological outcomes in cervical SCI.
• This study represents the largest cohort of cervical SCI patients treated with modest hypothermia.
• Further multi-center, randomized trials are warranted to confirm these findings and guide clinical practice.
