Abstract

The effect of excessive heat accumulated in the body is life threatening. It could damage not only body fluid electrolyte haemostasis, but kidney, liver, and hematologic function. The example reported herein was a Thai laborer, previously healthy, 32 years of age. He joined the tricycle race from Chiang Mai to Lumpoon, which is about 30 km. The tournament was held on a late morning of high humidity and a temperature of 35 degrees C. After biking 25 km, he began having heavy perspiration and suffered from severe myalgia and high fever. He suddenly lapsed into unconsciousness and fell down. He was admitted to the Lumpoon Hospital because of convulsions, and 2 days afterward, anuria, anemia, thrombocytopenia, coagulopathy, and liver impairment were detected. He was later transferred to the Faculty of Medicine for further intensive treatment. Lab analyses showed marked azotemia (BUN 96 mg%, Cr 10.6 mg%), elevation of muscle enzyme (CPK greater than 1000 U/L, SGOT greater than 650 U/L), liver failure (SGPT greater than 650 U/L, DB/TB = 23.0/30.0 mg%) and disseminated coagulopathy; platelet 17,000/mm3, PT 51.1 sec (control 12.5), and PTT 73.5 sec (control 37.7). He was treated with bicarbonated hemodialysis trice weekly. Blood-exchange transfusion was performed 3 times during the first 2 weeks with 10 units of fresh whole blood in each exchange. His ventilation required support by a ventilator. After a month, his consciousness, the liver function, and hematologic conditions became to recuperate. By 6 weeks postadmission, renal function eventually improved. This report is intended to warn the unprepared athlete entering an extreme, long-lasting exercise in an inappropriate climate.
