About this study
Official title: Randomized Double-blinded Study Designed to Optimize the Dose of Bupivacaine in Combined Spinal Epidurals to Reduce the Incidence of Fetal Bradycardia and Maternal Hypotension
The purpose of this study is to determine what dose of medication administered through a combined spinal epidural (CSE) provides the optimal pain relief with the minimal amount of side effects. The 3 doses studied here (1.25, 1.66 and 2.5mg) are routinely use on the labor floor (depending on the physician preference) but the idea is to quantify safety, efficacy and side effects for each of these doses.
Read the detailed description
A combined spinal epidural (CSE), which is the investigators' customary method of providing pain relief during your labor, is the identification of the epidural space in your lower back with a needle, followed by passing a thinner and longer needle through the first needle. This second needle will enter the patient's "spinal" (intrathecal) space by passing through the dura (thin covering separating the epidural space from the spinal space). The spinal (intrathecal) space is identified by flow of spinal fluid. The dura is the envelope around the spinal cord and the intrathecal space which is filled with spinal fluid. Medication will be injected at once into the spinal space, the thinner needle removed and a fine tube (catheter) will be threaded through the first needle into the epidural space. This catheter is in the epidural space and medication can be given through this catheter later on (hence the term combined) if needed. This study is a comparison of three different dosages (1.25mg, 1.66mg and 2.5 mg) of the local anesthetic (Bupivacaine) that we frequently use in the spinal, mixed with 20 mcg of Fentanyl (also routinely used in standard of care practice), and of its effects on the patient's blood pressure (risk of maternal's drop of the blood pressure with possible bad effects on the blood flow to the baby), on the patient's baby's heart rate (risk of slowing down of the baby heart rate as a consequence of decreased blood flow to the baby), and the patient's pain relief (higher dose of medications are usually more effective for maternal pain relief but have side effects that can be bad for the mother and the baby). The doses of Bupivacaine the investigator routinely use on the labor and delivery floor go from 1.25 to 2.5 mg depending on clinician preferences. These doses are considered standard of care in the literature.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maternal Blood Pressure
Maternal diastolic blood pressure at 60 minutes after epidural to measure maternal hypotension
Measured: at 1 hour
Secondary outcomes (2)
Fetal Heart Rate at 1 Hour
Baby's heart rate recorded with the external monitor that is placed on patient's belly, for a duration of 60 minutes after the placement of the combined spinal epidural.
Measured: at 1 hour
Mean Change in Visual Analog Scale for Pain
Mean change of her pain relief from the spinal epidural 60 minutes after she received it, using a VAS, scored from 0 to 10, with higher score indicating more pain.
Measured: baseline and 60 minutes

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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 Blood Pressure (time frame: at 1 hour). 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 3 Jan 2019; AzTrials last refreshed its copy on 8 Nov 2026.
