Objective: To describe the clinic manifestations of heat stroke in infants during El Niño phenomena. Material and methods: We included 13 infants with heat stroke (HS) criteria, attended at the Hospital Nacional Cayetano Heredia between Jan 1º and Mar 31, 1998. We registered hematocrito, coagulation tests, hepatic and renal function tests, blood gas analysis, serum and urinary electrolytes and urinary flux, intravenous solution used in hydrated therapy and outcome condition. Results: 4/13 died, 4/13 lived with serious neurological sequels. The clinic manifestations more important were convulsions (77%), respiratory distress (85%), water deficit (77%), shock (61%), acute diarrhea (85%) and polyuria (75%). In the laboratory test, was found anemia (84%), leukocytosis (60%), prolonged prothrombin time (53%), hyperglycemia (53%), elevated serum aminotransferases (83%), hyponatremia (84%), hypokalemia (70%), elevated serum creatinine (84%), elevated serum urea (53%) and metabolic acidosis (100%). Statistic association was found only among prolonged prothrombin time and use of hypertonic solutions in initial therapy with bad outcome condition. Conclusion: HS had grave prognostic which prolonged prothrombin time and use of hypertonic solutions in initial therapy were associated with died risk or grave neurologic sequels.
