Consensus on Use of Insulins in Gestational Diabetes.

INTRODUCTION

Gestational Diabetes Mellitus (GDM), diabetes diagnosed during pregnancy is associated with maternal (caesarean delivery, hypoglycaemia, hyperbilirubinaemia, shoulder dystocia, pre-term delivery and birth trauma) and fetal (Hyperbilirubinaemia in offspring, Neonatal hypoglycaemia, Macrosomia) complications. Despite, insulin being the standard treatment for GDM cases, there is no existing comprehensive consensus update on use of insulin in Indian patients with GDM.

OBJECTIVE

To provide simple and easily implementable guidelines to healthcare physicians on use of insulin in GDM.

METHODS

Each consensus based on indications, choice of insulin regimen , titration and insulin therapy during intrapartum and postpartum was presented based on established guidelines and published scientific literature. These evaluations were then factored into the national context based on the expert committee representatives' patient-physician experience in their clinical practice and common therapeutic practices followed in India for successful GDM management.

RESULTS

Recommendations based on use of insulin in GDM has been developed. The key recommendations are:to monitor fasting plasma glucose (FPG) and 2-hour post prandial glucose PPG levels and the glycaemic targets are: FPG < 95 mg/dL and 2-hour PPG < 120 mg/dL, short-and intermediate acting human insulin are the first choice of insulin regimens, rapid-acting (Insulin Aspart or Lispro) may be considered, use basal/intermediate acting insulin at bedtime, if FPG>110 mg/dL. During intrapartum, start IV insulin infusion with hourly glucose monitoring. Those women who require insulin < 20 U over 24 hours prior to labor may not need interpartum use of insulin infusion and Insulin dosing is stopped after birth and capillary glucose monitoring for 24-48 hours.

CONCLUSIONS

We hope that the consensus based recommendations mentioned in this paper will be a useful reference tool for healthcare practitioners to achieve glycaemic targets in GDM patients.
