Objectives: To review diabetic ketoacidosis, including the two bags system, a method of administering liquids in order to provide a smoother correction of the hyperglycemic and ketotic states.Methods: Review of recent publications (last 7 years) from a Medline search and chapters published in pediatric textbooks that discuss the etiology, therapy, and complications of diabetic ketoacidosis. The management approach incorporates the findings of these publications as well as the clinical experience at the Childrens Hospital of Philadelphia and Duke University Medical Center.
Results:The pathology of the type 1 Diabetes Mellitus involves the progressive destruction of the ß cells of the pancreas, causing insulin deficiency. Insulin is essential in the metabolism of carbohydrates, protein and fat. Insulin deficiency may lead to diabetic ketoacidosis which has three components: 1) hyperglycemia, which causes glycosuria and consequently dehydration; 2) lipolysis which, causes ketonemia/ketonuria; and 3) acidosis, that is caused by the dehydration and the high serum levels of ketones. Diabetic ketoacidosis is a serious condition and, if not treated appropriately, can cause coma and death. In children cerebral edema is the major complication of the therapy for diabetic ketoacidosis. Careful replacement of insulin, fluids, glucose and electrolytes is essential.
Conclusions:The literature presents different ways to manage DKA in pediatrics, without a consensus on the cause of the most important complication (cerebral edema), and consequently without a consensus on the best approach.The use of the two saline bags in patients in DKA allows fast adjustments in the dextrose concentration of the infusion fluids, simplifying and reducing the costs of the treatment of diabetic ketoacidosis.J Pediatr (Rio J) 2001; 77(1): 9-16: diabetes mellitus, cerebral edema, diabetic ketoacidosis, fluid therapy.
ResumoObjetivo: Rever vários aspectos da cetoacidose diabética, incluindo o sistema de duas soluções, um método de administrar líquidos que proporciona correção mais suave do estado de hiperglicemia e de cetose.Métodos: Revisão de publicações recentes (dos últimos 7 anos) referidas na base de dados da Medline e capítulos de livros de pediatria que abordam a etiologia, o tratamento e as complicações da cetoacidose diabética. O tratamento aqui apresentado utiliza a informação encontrada nestes artigos e a experiência clínica adquirida no Childrens Hospital of Philadelphia e no Duke University Medical Center.Resultados: A patologia do diabetes mellitus tipo 1 envolve a destruição das células ß do pâncreas, causando uma deficiência de insulina. A insulina é essencial para o metabolismo de carboidratos, proteínas e gorduras. A deficiência de insulina pode levar a um quadro de cetoacidose diabética que apresenta três componentes: 1) a hiperglicemia, que causa glicosúria e conseqüentemente desidratação; 2) a lipólise em excesso, que causa aumento nos níveis séricos e urinários de corpos cetônicos; e 3) a acidose metabólica, que é causa...
