Glycemic Control After Antenatal Corticosteroids in Women With Pregestational and Gestational Diabetes

After antenatal corticosteroid administration, women will continue to receive long- and short-acting subcutaneous insulin injections as prescribed at home. In addition, they will receive supplemental short-acting insulin using a sliding scale based on postprandial glucose values. Capillary blood glucose values will be measured with fingersticks 4 times daily (fasting and 1-hour postprandial).

After antenatal corticosteroid administration, women will receive long- and short-acting subcutaneous insulin injections at increased dosages compared to that prescribed at home. Insulin will be increased by 30% on the day that they receive their 1st dose of antenatal corticosteroids (day 1), 50% on day 2, 50% on day 3, 30% on day 4, and 15% increase on day 5. On day 6 they will return to their home insulin regimen. Capillary blood glucose values will be measured with fingersticks 4 times daily (fasting and 1-hour postprandial).

After antenatal corticosteroid administration, women will discontinue their home insulin regimen and be placed on a continuous insulin infusion with insulin boluses and titration of infusion rate per institutional L\&D protocol. Capillary blood glucose values will be measured with fingersticks every hour.
