Quad Fever: Treatment through Lowering of Ambient Temperature

Hyperpyrexia is a rare and at times fatal condition seen in an Intensive Care Unit setup. We encountered a case of a 65-year-old patient with road traffic accident presenting with dorsal spine fracture at D₁₀ level. He underwent decompression and fusion for the same. He developed hyperpyrexia of sudden onset on the 10^th day of admission with no source of infection and adequate broad-spectrum antibiotic coverage with adequate thrombo-embolic prevention in place. The patient showed no response to antipyretic agents and other cooling methods. The origin of hyperthermia was idiopathic, and we speculate that the cause was secondary to hyperthermic thermoregulatory dysfunction often quoted as "quad fever," seen in spinal cord injury. We present a brief review of literature and the importance of early identification and treatment of this potentially fatal condition.
