About this study

Official title: Effect of Intrapartum Glucose With Compared to Without Constant Intravenous Insulin on Neonatal Hypoglycemia Among Diabetic Women. A Randomized Controlled Trial

This study aims to examine the effect of intrapartum treatment of diabetic women with combined glucose and constant insulin infusion compared to glucose alone on the incidence of neonatal hypoglycemia. Pregnant women with diabetes in pregnancy will be randomly divided during labor to 2 groups: group 1, will receive intravenous glucose with constant insulin infusion; group 2 will receive intravenous glucose alone. The primary outcome is the incidence of neonatal hypoglycemia.

Read the detailed description

About 2 to 9% of pregnant women are diagnosed with gestational diabetes. Peripartum complications attributed to diabetes include: birth trauma, neonatal hypoglycemia and hyperinsulinemia and neonatal hyperbilirubinemia. The incidence of neonatal hypoglycemia is about 40%. Strict glycemic control may lower the risk of neonatal complications. There is a lack of evidence on how to manage women with diabetes during labor. Previous studies recommended the use of intravenous saline solution boosted with 5% glucose and insulin as needed, glucose 5% with constant insulin infusion and others recommended the use lactated Ringer's solution. Most of these studies are either retrospective or have a small number of participants.

In this study we will examine the effect of 2 different protocols on glycemic control during labor and the immediate neonatal period. Women in group 1, will receive intravenous saline solution boosted with 5% glucose and constant insulin infusion. Women in group 2, will receive intravenous saline solution boosted with 5% glucose alone. The desirable intrapartum glucose level will be 70 to 100 mg/dL. Glucose levels will be checked hourly. Women in both groups will receive additional insulin infusion in cases of glucose levels above 100 mg/dL. Additionally, the 5% glucose solution will be substitute with lactated Ringer's solution in cases of glucose levels above 140 mg/dL.

Intravenous fluid regimens will be assigned according to a computer randomization sequence generation program. Women will randomly assigned to the 2 groups in a 1:1 ratio. The randomization sequence results will be kept in the delivery ward in a closed study box. Site investigators will enroll participants after confirming eligibility. The sequence will be concealed until intervention is assigned (and after obtaining a signed informed consent).

Our hypothesis is that 5% glucose combined with constant insulin infusion will achieve better glycemic control and thus will lead to lower rate of neonatal hypoglycemia. In order to detect a reduction of neonatal hypoglycemia from 40% to 20%, 182 women will be needed in both groups in order to achieve a level of significance of 95% (α, 2-sided = 0.05) and a power of 80% (β = 0.2).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • glucose solution and InsulinDrug

    Also called Group 1

    Women in group 1, will receive intravenous saline solution boosted with 5% glucose combined with 8 units of insulin at a rate of 125mL/h. The desirable intrapartum glucose level will be 70 to 100 mg/dL. Glucose levels will be checked hourly.

    Glucose level between 100-140 mg/dL will be treated with additional intravenous insulin, 1 units/hour.

    Glucose level between 141-160 mg/dL will be treated with intravenous insulin, 2 units/hour. Additionally, the 5% glucose solution will be substitute with lactated Ringer's solution.

    Glucose level between 161-200 mg/dL will be treated with intravenous insulin, 4 units/hour.

    Glucose level above 200 mg/dL will be treated with intravenous insulin, 6 units/hour.

  • glucose solution onlyDrug

    Also called Group 2

    Women in group 2, will receive intravenous saline solution boosted with 5% glucose only, at a rate of 125mL/h. Women in this group will be treated similar to group 1 if glucose levels crossed over 100 mg/dL.

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Gali Gali, MD (972-4-6494035, galit_ga@clalit.org.il), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Neonatal hypoglycemia (time frame: 2-3 hours postpartum). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03273881, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Oct 2023.
