Acetaminophen for Fetal Tachycardia: a Randomized Pilot Trial
A study testing Acetaminophen 975 mg in people with Fever and Heart Rate, Fetal (FHR), run by Weill Medical College of Cornell University at 1 site in United States.
Trial summary
The most common cause of fetal tachycardia is maternal fever. Fetal tachycardia often precedes the maternal fever, and fetal tachycardia confounds the interpretation of electronic fetal monitoring (EFM), increasing the rate of cesarean delivery for non-reassuring fetal status (NRFS).

About this study
The most common cause of fetal tachycardia is maternal fever. Fetal tachycardia often precedes the maternal fever, and fetal tachycardia confounds the interpretation of electronic fetal monitoring (EFM), increasing the rate of cesarean delivery for non-reassuring fetal status (NRFS). Our hypothesis is that treatment of fetal tachycardia with acetaminophen will significantly lower maternal body temperature and significantly lower baseline fetal heart rate (FHR). The importance is that interpretation of EFM will improve, thus allowing for a decrease in cesarean delivery for NRFS.
Read the detailed description
This trial is a randomized, non-placebo controlled, assessment of whether acetaminophen can lower maternal temperature and baseline fetal heart rate in laboring patients with fetal tachycardia.
Term singleton cephalic pregnancies in active phase labor (spontaneous or induced) with fetal tachycardia will be recruited. Patient will be excluded for:
- Exclusion criteria (prior to randomization):
- Acetaminophen allergy
- Clinical chorioamnionitis
- Maternal fever
- Non-reassuring fetal status (NRFS), which is the designation for fetal heart rate abnormalities requiring cesarean delivery
- Previous cesarean delivery
- Multifetal gestation
- Breech presentation
- Known fetal anomaly
- Known contraindication to vaginal delivery
Primary outcome measures are:
- Maternal body temperature (oral) 90 minutes after treatment
- Baseline FHR
Secondary outcome measures are:
- Temperature difference before and after treatment
- Rate of cesarean delivery
- Rate of determination of NRFS
- Rate of subsequent development of maternal fever
- Rate of diagnosis of clinical chorioamnionitis
- Rate of neonatal sepsis
Power calculation Internal data collection at our institution of 53 patients showed a mean decrease in temperature of patients in labor with fever receiving acetaminophen is 0.3 degrees C measured an average (mean) of 90 minutes after administration of acetaminophen. Mean oral temperature before acetaminophen was 38.32, SD 0.33. Mean oral temperature after acetaminophen was 38.03, SD 0.85.
Sample size calculation shows that 27 patients are needed in each group to show significant difference using alpha 5% and beta 50%.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maternal Body Temperature 90 Minutes After Randomization
Fever in labor is identified,consenting and randomization occurs, either acetaminophen is given or no medication is given, then 90 minutes later maternal temperature is recorded.
Measured: 90 minutes
Baseline Fetal Heart Rate (FHR) After Treatment
Measured: 90 minutes
Secondary outcomes (6)
Temperature Difference Before and After Treatment
Maternal temperature difference before randomization and 90 minutes after randomization in degrees Centigrade
Measured: 90 minutes
Rate of Cesarean Delivery
Rate of cesarean delivery
Measured: Labor--up to 24 hours
Rate of Determination of Non-reassuring Fetal Status
Non-reassuring fetal status is when cesarean delivery or operative vaginal delivery (forceps or vacuum) are performed for fetal heart rate abnormalities.
Measured: Labor--up to 24 hours
Rate of Subsequent Development of Maternal Fever
Rate of subsequent development of maternal fever, i.e., the number of participants who developed fever.
Measured: Labor--up to 24 hours
Rate of Diagnosis of Clinical Chorioamnionitis
Rate of diagnosis of clinical chorioamnionitis, i.e., the number of participants who developed chorioamnionitis.
Measured: Labor--up to 24 hours
Rate of Neonatal Sepsis
the number of participants who developed neonatal sepsis
Measured: 7 days

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The most common cause of fetal tachycardia is maternal fever. Fetal tachycardia often precedes the maternal fever, and fetal tachycardia confounds the interpretation of electronic fetal monitoring (EFM), increasing the rate of cesarean delivery for non-reassuring fetal status (NRFS). Our hypothesis is that treatment of fetal tachycardia with acetaminophen will significantly lower maternal body temperature and significantly lower baseline fetal heart rate (FHR). The importance is that interpretation of EFM will improve, thus allowing for a decrease in cesarean delivery for NRFS.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?
Maternal Body Temperature 90 Minutes After Randomization (time frame: 90 minutes). The study lists 2 primary outcomes in all. 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 16 Sep 2013.
