Objective      To determine the curative effect of continuous glucose monitoring combined with dual-wave bolus of insulin pump in the treatment of gestational diabetes mellitus (GDM).       Methods      Twenty normal pregnant women and 46 pregnant women with GDM were selected in the study

and 46 pregnant women with GDM were randomly divided into a normal-wave bolus of insulin pump therapy group and a dual-wave bolus of insulin pump therapy group. All the pregnant women received continuous glucose monitoring. The mean blood glucose (MBG)

mean amplitude of glycemic excursion (MAGE)

postprandial glucose excursions (PPGE)

largest amplitude of glycemic excursions (LAGE)

frequency of hypoglycemic incidence and pregnancy outcomes were compared.       Results       Compared with the normal-wave bolus of insulin pump therapy group

the MAGE (2.26±0.94 vs 3.52±1.41 mmol/L)

PPGE

LAGE (4.24±0.40 vs 6.56±1.32 mmol/L)

and caesarean section rate (8.7% vs 34.78%) were lower in the dual-wave bolus of insulin pump therapy group (P0.05

P0.01).       Conclusion       Compared with normal-wave bolus of insulin pump therapy

dual-wave bolus of insulin pump therapy shows better glucose control stability for the pregnant women with GDM

and can effectively reduce the cesarean section rate.
