Effect of continuous glucose monitoring system to pregnancy outcome in gestational diabetes mellitus

Objective To investigate the influence of pregnancy outcome in GDM patients by continuous glucose monitoring system(CGMS). Methods 60 patients with GDM in Longgang District People's Hospital of Shenzhen City from January 2011 to December 2012 were selected and divided into group A and group B with 30 cases in each group. The group A was treated with continuous glucose monitoring for 24 h, group B was treated with normal peripheral blood sugar checking without continuous glucose monitoring. The indexes were observed and compared: ①the occurrence rate of perinatal complications of pregnancy induced hypertension, premature birth, intrauterine infection, polyhydramnios, premature rupture of fetal membranes, cesarean delivery in pregnant women of the two groups; ②the occurrence rate of hyperbilirubinemia, hypoglycemia, perinatal death, asphyxia neonatorum, fetal macrosomia, weight and gestational age in newborn of the two groups. Results ①The occurrence rate of pregnancy induced hypertension, pregnancy induced hypertension, intrauterine infection, polyhydramnios, premature rupture of fetal membranes, caesarean section in group B [13.33%(4/30), 6.67%(2/30), 6.67%(2/30), 6.67%(2/30), 10.00%(3/30), 53.33%(16/30)] were all higher than those in group A [6.67%(2/30), 3.33%(1/30), 0.00%(0/30), 0.00%(0/30), 3.33%(1/30), 40.00%(12/30)], the differences were statistically significant(P 0.05). ②Thehyperbilirubinemia,hypoglycemia,newbornweight, neonatal asphyxia, fetal macrosomia in group B [13.33%(4/30), 6.67%(2/30),(3345±512) g, 6.67%(2/30), 6.67% (2/30)] were all higher than those in group A [6.67%(2/30), 0.00%(0/30),(3045±460) g, 0.00%(0/30), 0.00%(0/30)], the differences were statistically significant(P 0.05). Conclusion It is able for CGMS to provide the early dynamic blood sugar monitoring for GDM patients, it also can provide more accurate blood sugar basis for the subsequent treatment, it is one of the methods to reduce the maternal complications and complications effectively.
