About this study

Official title: A Randomized Controlled Trial Comparing Normal Saline With and Without Dextrose on the Course of Labor in Nulliparas

The purpose is to determine in term nulliparas with singletons that present in active labor (3-5 cm) or with ruptured membranes whether the administration of dextrose solutions to normal saline improves or expedites the course of labor. The researchers' hypothesis is that the addition of a carbohydrate substrate will shorten the length of labor and facilitate a vaginal delivery.

Read the detailed description

Factors that affect the course of labor have been studied extensively. Surprisingly, there is little data on the effect that different types and rates of intravenous (IV) fluids have during labor. Exercise physiologists have shown that increased fluid intake and carbohydrate replacement improve skeletal muscle performance in prolonged exercise. In a 1992 randomized, controlled study comparing IV fluid rates, Garite et al. showed a lower frequency of prolonged labor, and possibly a decreased need for oxytocin, with higher IV fluid rates in labor. Inadequate hydration may contribute to dysfunctional labor and possibly an increased rate of cesarean section.

We propose that inadequate carbohydrate replacement in labor may also contribute to prolongation of labor and increased need for operative delivery. Glucose is the main energy supply for the pregnant uterus. Physiological requirements for glucose during labor are approximately 10 grams per hour. Adequate supplies of glucose are needed to maintain exercise tolerance and muscle efficiency, which are important factors in the progress of labor. Dysfunctional labor or dystocia, which is the leading indication for primary cesarean delivery, is caused by uterine forces insufficiently strong or inappropriately coordinated to efface and dilate the cervix. Dystocia can also be a result of inadequate voluntary muscle effort in the second stage of labor. It contributes to increased risk for chorioamnionitis, which is a leading cause of maternal and fetal morbidity and mortality. Supplying carbohydrate fuel for working uterine and skeletal muscle may improve progress in labor and, therefore, diminish risk for chorioamnionitis and need for cesarean delivery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Carbohydrate solutions can decrease the total duration of labor by 20% (from 560 minutes to 450 minutes)

    Measured: Prospective

Secondary outcomes (4)
  1. Carbohydrate solutions can decrease the incidence of prolonged labor (> 12 hours

    Measured: Prospective

  2. Carbohydrate solutions can decrease the incidence of chorioamnionitis during labor

    Measured: Prospective

  3. Carbohydrate solutions can decrease the need for oxytocin (a contraction stimulant) augmentation of labor

    Measured: Prospective

  4. Carbohydrate solutions can decrease the frequency of cesarean sections for prolonged labor

    Measured: Prospective

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing D5NS, D10NS and NS in people with Labor, run by MemorialCare.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Dec 2007. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Carbohydrate solutions can decrease the total duration of labor by 20% (from 560 minutes to 450 minutes) (time frame: Prospective). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 7 Dec 2007.
