RT Journal A1 Goldman SL T1 HYperglycemic hyperosmolar coma in a 9-month-old child JF American Journal of Diseases of Children JO American Journal of Diseases of Children YR 1979 FD February 1 VO 133 IS 2 SP 181 OP 183 DO 10.1001/archpedi.1979.02130020073015 UL http://dx.doi.org/10.1001/archpedi.1979.02130020073015 AB • Hyperglycemic hyperosmolar coma is a life-threatening emergency with a mortality much higher than that of other forms of hyperosmolarity such as hypernatremia or diabetic ketoacidosis. Despite the differences in the three conditions, present evidence suggests that correction of hyperosmolarity should proceed slowly to avoid the seizures that may occur in all three conditions.This report describes a 9-month-old diabetic child who initially had hyperglycemic hyperosmolar coma and who is one of the youngest survivors of this syndrome in the American literature. This case report points out the limited understanding of the pathophysiology of this syndrome and the consequent problems of therapy.(Am J Dis Child 133:181-183, 1979)
