Pregnancy Related Clinical Trial
Official title:
Closed-Loop Insulin Delivery Postpartum in Mothers With Type 1 Diabetes and Their Babies' Feeding Practices
This study will is a parallel two-group randomized controlled trial that will use the MiniMed 670G hybrid closed-loop system's continuous glucose monitor (GCM) insulin pump and computer algorithm to deliver insulin when in "auto mode". This study will be conducted in women with type 1 diabetes after delivery of their neonate to see if "auto-mode" improves blood sugar control, episodes of low blood sugar, burden of diabetes self-care, alters baby's weight and feeding patterns, and partner diabetes distress.
Women work very hard prior during pregnancy to try to control their blood sugars. However, after delivery, women often feel they need a rest from the intense effort they have put into diabetes self-care during pregnancy due to the demands of caring for a newborn, breastfeeding, and sleep deprivation. Attention to blood sugar control after delivery remains important because these new factors a may increase the risk of nighttime low blood sugar and unrecognized low blood sugar. Blood sugar has been shown to influence the sugar levels in breastmilk. How this affects the child has not been well study. The MiniMed 670G hybrid closed-loop system uses a continuous glucose monitor (GCM) insulin pump and computer algorithm to deliver insulin when in "auto mode". The system uses input about the individual's glucose values obtained from the continuous glucose sensor (CGM) to adjust the amount of insulin that is needed between meals and overnight. Manual mode of the insulin pump delivers insulin based on preprogrammed insulin delivery settings on the insulin pump regardless of the person's glucose levels. This is a randomized controlled pilot trial followed by an observational cohort study in postpartum women with type 1 diabetes, of the MiniMed 670G hybrid closed-loop insulin delivery system with early 6 to 10 days postpartum) versus delayed (12 weeks postpartum) auto mode enabled MiniMed 670G hybrid closed-loop insulin delivery system. This study will assess the impact of auto mode enabled hybrid closed-loop on glycemic control, occurrence of maternal hypoglycemia, and burden of diabetes self-care, infant weight and feeding practices. The investigators will also assess the acceptability of the auto mode enabled MiniMed 670G during lactation and postpartum and the feasibility of conducting a larger multicentre trial. ;
