Early General Anesthesia to Limit Experiences of Trauma During Cesarean Section-Pilot Study (EAGLET-CS)

June 9, 2026 updated by: Mark Neuman, University of Pennsylvania

EAGLET-CS Pilot: Early General Anesthesia to Limit Experiences of Trauma During Cesarean Section-Pilot Study

Some patients who undergo cesarean section under spinal or epidural anesthesia can experience severe pain. Some patients who experience this kind of pain can experience symptoms of post-traumatic stress disorder (PTSD) after pregnancy. Currently, the two main options for treating this pain are general anesthesia (full medically induced unconsciousness) and using intravenous medications to reduce the pain and decrease anxiety. The EAGLET-CS Pilot is a pilot randomized trial that will test the feasibility of comparing the impact of these two options for preventing PTSD in a rigorous way for those patients who experience pain during their cesarean section after the baby is out.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The EAGLET-CS Pilot is a randomized trial that will assess the feasibility of comparing two commonly used approaches to care for women undergoing cesarean delivery under standard neuraxial anesthesia (epidural, spinal, or CSE) who experience intraoperative pain after delivery that is refractory to first line treatments. 12 patients recruited from the labor and delivery service at the Hospital of the University of Pennsylvania will be assigned to one of two standard-care comparators, namely early conversion to general anesthesia versus a time-limited trial of intravenous sedation, followed by conversion to general anesthesia if needed due to ongoing pain. Patients will be assessed during hospitalization and at up to 6 weeks after delivery to assess mental health, medical, and quality of recovery outcomes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Women aged 18 or older undergoing non-emergent cesarean delivery with primary neuraxial (epidural, spinal, or CSE) anesthesia. Eligible patients will be those who report severe pain during surgery, defined as pain that does not resolve with 2 trials of first-line pharmacologic therapies (e.g., epidural supplementation with local anesthetics; intravenous opioid analgesics).

Exclusion Criteria:

  • We will exclude patients who require induction of general anesthesia prior to umbilical cord clamping and by clinician determination.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
