Management of Hypothermia and Hypotension in Acute Cervical Spinal Cord Injury

Critical Temperature Management Priority

The primary temperature concern in acute cervical spinal cord injury is hypothermia prevention, which is life-threatening and increases mortality, according to the Critical Care society 1, 2
Remove wet clothing immediately and cover the patient to prevent additional heat loss, as recommended by the Critical Care society 1, 2
Increase ambient temperature in the treatment area to prevent hypothermia, as suggested by the Critical Care society 1, 2
Apply forced air warming devices as first-line active warming to maintain normothermia, according to the Critical Care society 1, 2
Administer warm intravenous fluids to prevent hypothermia, as recommended by the Critical Care society 1, 2, 3
Target normothermia: core temperature 36-37°C to optimize coagulation and prevent the lethal triad, according to the Critical Care society 1, 2
Each 1°C drop below normal reduces coagulation factor function by 10%, and temperatures below 34°C severely compromise blood coagulation, as stated by the Critical Care society 1, 2, 3

Hypotension in cervical spinal cord injury is often multifactorial: neurogenic shock, hypovolemia from trauma, and hypothermia-induced cardiac dysfunction, according to the Critical Care society 2
Administer warm crystalloid or blood products as indicated, avoiding cold fluids that worsen hypothermia, as recommended by the Critical Care society 1, 3
Target systolic blood pressure 80-100 mmHg during initial resuscitation, although the source of this recommendation is not explicitly stated in the provided citations

Only use vasopressors transiently if life-threatening hypotension persists despite adequate volume resuscitation, as suggested by the Critical Care society 2
Norepinephrine is the vasopressor of choice, although the initial dose and titration protocol are not explicitly cited from a reputable source in the provided text
Early vasopressor use before adequate volume resuscitation may be deleterious and should be used cautiously, according to the Critical Care society 2
Assess cardiac function with ultrasound before escalating vasopressors, as myocardial dysfunction from cardiac contusion or hypothermia may require inotropic support instead, as recommended by the Critical Care society 2
Vasopressors increase cardiac afterload and can worsen outcomes if left ventricular function is impaired, according to the Critical Care society 2

Do not assume hyperthermia is the problem—hypothermia is far more dangerous and common in acute cervical spinal cord injury, as stated by the Critical Care society 1, 2, 3
Do not administer cold intravenous fluids, which significantly worsen hypothermia and increase cardiac arrest risk, according to the Praxis Medical Insights society 3
Do not use vasopressors before correcting hypovolemia, as this worsens outcomes in hemorrhagic shock, as recommended by the Critical Care society 2
Do not diagnose neurogenic fever without ruling out infection first, particularly pneumonia which is common in cervical spinal cord injury, according to the Praxis Medical Insights society 4
Do not use therapeutic hypothermia in acute cervical spinal cord injury, as evidence is too sparse to recommend it, and preventing spontaneous hypothermia takes priority, as stated by the Neurosurgery society 6
