Other: D5 Lactated Ringers Solution (D5LR)
IV fluid 125 ml/hr infusion rate
Other Name: IV fluid containing glucose
Active Comparator: Lactated Ringers solution (LR)

Other: Lactated Ringers Solution (LR)
IV fluid 125 ml/hr infusion rate

Detailed Description:

This will be a multi-center, prospective, single-blind randomized trial of two types of IV fluids for maintenance hydration during labor. This study will be conducted at 4 sites: Reading (Reading Hospital), Allentown (Lehigh Valley), St. Luke Hospital and Hershey (Penn State College of Medicine). It will include 1524 pregnant women at ≥ 36 weeks presenting in spontaneous labor for anticipated delivery.

The primary research hypothesis is that intravenous hydration during labor with a glucose-containing fluid will lead to more efficient uterine contractility and will lead to a reduction of cesarean delivery. The primary outcome measure is the occurrence of a cesarean birth during the study period. The primary analysis will use an intent-to-treat approach to examine differences between the two IV fluid treatments in the proportion of deliveries requiring cesarean section.


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Women of any age with a singleton gestation in spontaneous labor at greater than or equal to 36 weeks without contraindication to participation.
  2. These women will be in good health and candidates for vaginal delivery.

Exclusion Criteria:

  1. Patients who are not candidates for vaginal delivery. This may be due to fetal malpresentation, prior cesarean section, multiple gestations, etc.
  2. Patients presenting for induction of labor or requiring induction upon admission.
  3. Patients presenting for scheduled cesarean section.
  4. Patients with any form of diabetes or glucose dysregulation condition.
  5. Concurrent use of steroids.
  6. Patients presenting in active labor with advanced cervical dilation (≥ 6 cm).
  7. Subjects participating in another labor and delivery related clinical trial that conflicts with this trial (as determined by the site PI).
