DOPPLER VELOCIMETRY AND BEHAVIORAL STATE DEVELOPMENT IN RELATION TO PERINATAL OUTCOME IN PREGNANCIES COMPLICATED BY GESTATIONAL DIABETES

Seventy-one pregnancies complicated by gestational diabetes and 100 he althy pregnancies were monitored on two occasions (between 27th-32nd a nd 33rd-36th week of gestation) by behavioural state analysis (1F coin cidence; 2F coincidence) and umbilical artery Doppler velocimetry (UA) (Resistance Index, RI). The purpose of our study was to determine if the development of behavioural states and Doppler velocimetry: (1) dif fer between normal and gestational diabetic cases; (2) in gestational diabetic cases, are they related to the degree of abnormality of the m aternal oral glucose tolerance test (OGTT)?; and (3) are they predicto rs of perinatal outcome? (i.e, emergency caesarean section; low Apgar scores; respiratory distress syndrome; neonatal hypoglycaemia and neur ological abnormality in the neonate and/or at 4 months of age), Our fi ndings suggest that: (1) results on behavioural state development and Doppler velocimetry were significantly different in gestational diabet ic cases; (2) infants of women with gestational diabetes who are neuro logically abnormal during the newborn period, had a poor development o f coincidence 2F during fetal life and had neonatai hypoglycaemia more often than infants with a normal neurological outcome; (3) in cases w ith abnormal neurological outcome, the maternal diabetes was more seve re than in those cases with normal outcome.
