- Abstract: Heat stroke can be divided into two types: exertional and classic, mainly manifested as a clear history of exposure to hot temperature/high heat environment or intense physical activity in hot environment, core temperature exceeding 40 ℃, accompanied by central nervous system changes (altered consciousness, epilepsy, psychiatric symptoms, etc.) and multiple organ damage, including respiratory failure, impaired liver and kidney function, rhabdomyolysis, coagulation disorders, abdominal distension, and diarrhea. Its pathology may be manifested as organ endothelial cell damage, inflammatory response, extensive thrombosis, and bleeding tendency. The main treatment measures are cooling therapy, and when combined with other organ damage, organ support or replacement therapy should be carried out in time, including blood transfusion to improve coagulation function and blood purification therapy. Hyperbaric oxygen therapy may improve the prognosis of patients with ischemic hypoxic encephalopathy. We reported a case of a firefighter with sudden impaired consciousness and high fever during forest fire fighting. The patient was sent to a local hospital and his head computed tomography (CT) results showed unclear cerebral gyrus, suggesting severe cerebral edema, and finally diagnosed as heat stroke. After being transferred to Liuzhou Workers' Hospital, his condition continued to deteriorate and signs of multiple organ failure appeared. The patient's cerebral edema was reversed and further development of heat stroke was prevented through early cooling, sedation and anti-epilepsy, endotracheal intubation ventilator-assisted breathing, anti-infection, fluid resuscitation, infusion of fresh frozen plasma and platelets to improve coagulation function, immunomodulatory therapy, renal replacement therapy, and timely artificial liver therapy. Hyperbaric oxygen therapy was ordered during the rehabilitation phase, and the patient recovered well at discharge, leaving no obvious neurological sequelae. Its prognosis is much better than that predicted at admission.
