[Normalization of perinatal morbidity in gestational diabetes by strict metabolic adjustment]

A prospective study compared the perinatal morbidity of 141 normal pregnancies (group I) with that of 108 pregnancies in whom gestational diabetes had been treated early (group II) and 35 with unsatisfactorily treated gestational diabetes (group III). The therapeutic goal in gestational diabetes was to have a postprandial blood-glucose level of less than 130 mg/100 ml. If this was not achievable through diet alone, insulin was injected once daily. Neonatal macrosomia, dystrophy, acidosis, hyperbilirubinaemia, hypoglycaemia and hypocalcaemia had a normal incidence in group II, but in group III macrosomia was twice as frequent as in group II (P less than 0.02), and acidosis (pH less than 7.20) twice as frequent (P less than 0.05). The results indicate that strict metabolic control in gestational pregnancy will achieve a normal rate of perinatal morbidity.
