Study summary

Patient's with planned cesarean sections will be randomized to receive either standard 20 mU in 1L as a bolus following delivery of the placenta or 20 mu in 1L following delivery of the placenta plus an additional 20 mU in 1L over 8 hours.

Read the detailed description

The purpose of this study is to examine the impact of differential dose protocols commonly utilized in the post cesarean period to determine if laboratory definitions of anemia are different. Oxytocin is an antidiuretic hormone that is utilized after delivery of the fetus and placenta to contract the uterus and decrease blood loss both at the time of surgery and in the post-partum period. Here at the Penn State Hershey Medical center the investigators will use 20 units of oxytocin in a 1 L bag of LR in bolus fashion after delivery of the placenta. Other protocols use an extended course of therapy using 20 units of oxytocin in a 1 L bag of LR in a bolus plus an additional 20 units of oxytocin in a 1 L bag of LR over an 8 hour period of time.

We hypothesize that:

  • Women who receive the standard 20 mU of oxytocin in 1L of LR in bolus fashion plus 20 mU in 1L over 8 hours will have a decreased reduction in pre-operative vs post-operative hematocrit and hemoglobin versus those that receive 20 mU in 1L of LR.
  • Women who receive the standard 20 mU of oxytocin in 1L of LR in bolus fashion plus 20 mU in 1L over 8 hours will have decreased blood loss by weight in the postpartum period compared to patients who receive 20 mU in 1L of LR.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Planned cesarean sections for singletons at or greater than 37 weeks gestational age
  • Primary or repeat cesarean section will be included

Exclusion criteria

Exclusion Criteria:

  • Multiple fetal pregnancies
  • Hematologic disorders
  • Fetal anomalies
  • Pre-eclampsia. These patients are at increased risk of fluid overload and so fluid status may be affected by receiving a second bag of fluid containing oxytocin in the postpartum period.
  • Known to oxytocin
  • to oxytocin
  • Patients who have labored and then proceed with cesarean section for any reason. Patients who have labored have had either intrinsic or extrinsic exposure to oxytocin. These patients may have decreased sensitivity to oxytocin.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 21, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
