Abstract: Abstract Objective:To study the impact of glucose monitoring and controlling in women with abnormal glucose metabolism on maternal and neonatal outcomes.Methods:A retrospective study of maternal and neonatal outcomes was conducted in 172 pregnant women who were diagnosed and treated for abnormal glucose metabolism and delivered in the Second Hospital of Tianjin Medical University from January 2007 to January 2009. After diet control or diet control plus insulin therapy,172 patients were devided into two groups according wether blood glucose controlled satisfiied. While blood sugar was satisfied named A group(91 cases),the other patients named B group(81 cases). Compared the general situation and outcomes. Results:The incidence of HDCP，fetal distress, C-section and postpartum hemorrhage in group A was significantly higher than that in group B. The incidence of fetal macrosomia,hypoglycemia,neonatal asphyxia,transferring to NICU in group A was significantly lower than that in group B.No difference was shown between the two groups in the rate of ketonemia,intrauterine infection,polyhydroamnios deformity,NRDS.Conclusions: The glucose metabolism disorders is harmful for maternal and neonatal .The screening and diagnosis of glucose metabolism disorders during pregnancy should be strengthened. Controlling blood sugar in satisfied level is the key to decreasing maternal and neonatal complications.
