RESUMO
The fetal prognosis in pregnancy in a diabetic woman depends mainly on the blood sugar equilibrium of the mother that can be obtained, since the normal range lessens the chances of fetal abnormalities. This has been demonstrated in this series, since a system that uses the continuous automatic administration of insulin has been used. Six diabetic women were treated with continuous subcutaneous perfusion of insulin in the second half of pregnancy. The quality of the maternal blood sugar equilibrium has been proved by the normal values of glycosylated haemoglobin and the values of venous blood sugar which were always within the mean of the normal range. The tolerance of the technique is excellent (83 days in mean without a single complication). In 4 out of the 6 cases the baby was born at the 38th week of pregnancy and studies show that there was no increase in weight and a very low level of neonatal hypoglycaemia. It seems desirable to use this kind of insulin therapy which should help to contribute to a better fetal prognosis in diabetic pregnancies.
