RESUMO
Scorpion sting is a health problem in some places of Mexico. The clinical manifestations of scorpion envenomation are variable and include metabolic alterations. Hyperkalemia is the most frequently reported metabolic alteration. We conducted a prospective, observational, descriptive and transversal study in an emergency room at Hospital del Niño Morelense, Mexico. Eighty-two patients were included and classified as mild (17 percent) moderate (33 percent) and severe (46 percent). The mean serum level of sodium was 146.4meq/l, standard deviation (SD) 5.58; potassium 3.86meq/l, SD 0.53, and calcium 9.55mg/dl, SD 0.76. We found 30.4 percent hypernatremia, 12 percent hypokalemia, 10.9 percent abdominal distension, and 14.6 percent visual alterations.

Scorpionism is a public health problem in some places in Mexico. The clinical symptoms of envenomation by scorpion sting are by sympathetic and parasympathetic stimulation, developing systemic and local symptoms. The Central Nervous System (CNS) is one of the organs that are affected. In some cases, cerebral edema develops. In this report we present two pediatric cases with the association of envenomation by scorpion sting and cerebral edema. The first case developed severe cerebral edema, which progressed to a fatal outcome; and the other case developed mild cerebral edema with a satisfactory evolution. The pathophysiology of this complication is not well known and probably is the consequence of hypoxia, secondary to respiratory failure, laryngospasm and seizures that are manifestations of envenomation by scorpion sting
