title: Neurodevelopmental outcome of asymptomatic & symptomatic babies with neonatal hypoglycaemia.
abstract: A total of 107 babies with hypoglycaemia were studied over a period of 15 months. Symptomatic hypoglycaemia was found in 43 while it was asymptomatic in the others. Asymptomatic hypoglycaemia occurred at a relatively earlier post-natal age (4.5 +/- 2.2 h), as compared to symptomatic hypoglycemia (18.5 +/- 5.4 h, P less than 0.001). The mean blood glucose in hypoglycaemic babies with seizures was found to be significantly lower (P less than 0.001) when compared to those with other features as well as asymptomatic ones. Hypoglycaemia lasted for a significantly longer duration in symptomatic babies as compared to those without symptoms (P less than 0.001). On neurodevelopment follow up the mental developmental index (MDI) and the psychomotor developmental index (PDI) of symptomatic babies with seizures were significantly lower (P less than 0.001) as compared to those with other features of hypoglycaemia as well as asymptomatic babies. The neurodevelopmental status of babies with symptoms other than seizures was also significantly poorer (P less than 0.001), when compared to asymptomatic hypoglycaemic babies. The duration of hypoglycaemia was directly related to the MDI (r = -0.74, y = 102.5 - 0.69x) and PDI (r = -0.81, y = 105.6 - 0.86x). This study indicates that there is a need to identify babies vulnerable to symptomatic hypoglycaemia more precisely.
