Temperature dysregulation. Inability to sweat or shiver (poikilothermia) affects the patient’s temperature regulation and can worsen bradycardia. Poikilothermia is more likely to occur with higher-level SCIs and more complete motor impairment. Monitor environmental temperature, as this can affect body temperature. Hypothermia may worsen bradycardia and hypotension. Provide gentle rewarming and monitor core temperature continuously.
