Monitoring and analysis of dysglycemia in preterm infants

Objective: To study the monitoring methods,characteristics and risk factors of dysglycemia in preterm infants.Methods: The level of blood glucose in preterm infants was monitored and analyzed using the venous serum glucose determination and capillary whole blood glucose measurement.All preterm infants were intravenously injected with glucose,the capillary whole blood glucose in heel was dynamically monitored using blood glucose meter,and the concentration and velocity of glucose infusion were adjusted according to the monitoring results until the level of blood glucose was stable.The clinical data of all cases were retrospectively analyzed,and the characteristics and risk factors of dysglycemia were analyzed.Results: Among 118 preterm infants,the abnormal blood glucose rate,incidence rates of dysglycemia,hypoglycemia and hyperglycemia were 50.8%,49.2% and 1.69%,respectively.The low birth weight and asphyxia of newborn in preterm infants were the risk factors of venous hypoglycemia and peripheral blood hyperglycemia(P<0.05 to P<0.01).The cesarean delivery,low birth weight,twin pregnancy and asphyxia of newborn were the independent risk factors in peripheral blood hypoglycemia of preterm infants(P<0.05 to P<0.01).Conclusions: The incidence rate of dysglycemia in preterm infants is high,which should be actively monitored.Positive controlling the low birth weight and asphyxia of newborn is an important measure in reducing the abnormal glucose in preterm infants.
