What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compares whether measuring blood pressure continuously at the toe versus the arm better predicts newborn outcomes in women having planned C-sections under spinal anesthesia. Researchers will monitor 327 mothers with a noninvasive device on both a finger and a toe. The goal is to see if lower-extremity readings more accurately detect drops in blood pressure that could affect the baby's health right after birth.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could improve how doctors monitor blood pressure during C-sections, potentially leading to better newborn outcomes.
What could go wrong
This is an observational study, so it does not test a new treatment. Results may not change current practice or apply to all patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study includes adults, children, English- or Spanish-speaking individuals, and pregnant women (and their fetuses). It excludes adults with impaired decision-making capacity, nonviable neonates, neonates of uncertain viability, and prisoners. Eligible participants must be ≥18 years old, able to provide consent in English or Spanish, and have a singleton pregnancy at ≥37 weeks gestation. Exclusion criteria include documented fetal anomalies, congenital malformations, or genetic conditions; unstable cardiac disease (other than hypertensive disorders of pregnancy) that may affect blood pressure; and intrauterine growth restriction. Prisoners and other vulnerable populations are excluded.

Inclusion Criteria: * Age ≥ 18 years old * Singleton pregnancy * Gestational age ≥ 37 weeks * Women undergoing CD under SAB or Combined Spinal-Epidural (CSE) electively. * Ability to consent in English and in Spanish language Exclusion Criteria: * CD under or converted to general anesthesia * CD under epidural anesthesia or converted to epidural anesthesia * Diabetes Mellitus (DM)/Gestational Diabetes Mellitus (GDM) * Evidence of unstable cardiac disease other than HDP (including chronic hypertension, gestational hypertension, preeclampsia-eclampsia, and chronic hypertension with superimposed preeclampsia) judged by the investigator to have any impact on BP will make the subject unsuitable for participation in the study * Documented fetal anomaly/ congenital malformations and genetic syndromes * Intrauterine growth retardation * Unable to consent in English/Spanish. * Prisoners
