ABSTRACT
In a prospective study of 50 infants of diabetic mothers, 40% were large, 44% appropriate and 16% small for gestational age, 36% were preterm, 24% of the mothers were managed by dietary modification, 62% received insulin, 10% were treated with oral hypoglycemic agents while 4% did not receive any treatment as they were diagnosed postpartum, 58% mothers, underwent cesarean section (38% elective and 20% emergency procedures), 34% had normal vaginal deliveries, 6% were delivered by forceps and 2% by vacuum. Sixty-four per cent were infants of gestational diabetic (IGDM) and 36% of preconceptional diabetic mothers (IPDM). The morbidity and mortality was lesser in IGDM compared to IPDM. Hypoglycemia was documented in 50%, polycythemia in 20%, birth asphyxia in 18%, respiratory distress syndrome and hypocalcemia in 14% each, transient tachypnea of the newborn in 12%, hyperbilirubinemia in 8%, congenital anomalies in 4% and cardiomyopathy, birth trauma and meconium aspiration in 2% each. Pretherapy serum insulin levels were estimated in 10 babies, and 6 babies were subjected to 2D-echocardiography. The overall mortality was 20%. Infants born to mothers on oral hypoglycemic agents had a poor outcome.
