Umblical Artery Systolic \Diastolic Ratio and Amniotic Fluid Index in Prediction of Fetal Outcome in Term Pregnancy

Umblical Artery Systolic \Diastolic Ratio and Amniotic Fluid Index in Prediction of Fetal

Antepartum fetal surveillance is the cornerstone of management in pregnancy. [1] It is done primarily to reduce the incidence of adverse fetal outcomes. It minimizes morbidity by optimizing the timing of delivery. Fetus at risk of chronic hypoxia is identified and unnecessary interventions are avoided. However, fetal surveillance acts as a diagnostic modality to detect the influence of maternal, placental, and fetal factors on the fetus. The timely detection of morbid changes in the fetal status followed by adequate interventions to avoid death or disability is one of the most important objectives of prenatal care. [2] Tests now commonly done for antepartum fetal surveillance are nonstress test (NST), amniotic fluid index (AFI), biophysical profile, Doppler study of umbilical artery (UA), and middle cerebral artery (MCA).[3 6] However, AFI and UA Doppler velocimetry both form an essential part of the antenatal surveillance in the assessment of fetal well being. UA Doppler is a powerful tool that allows the obstetrician to follow a sequence of fetal hemodynamic events that happen in response to placental insufficiency. [7] However, several studies have reported higher sensitivities and specificities for UA Doppler ratio for prediction of fetal prognosis. [3 6] Amniotic fluid is the product of complex and dynamic fetal and placental physiologic processes. Disruption of the fine balance may result in overproduction or underproduction of fluid. Liquor adequacy often reflects the fetal status. Oligohydramnios is associated with increased perinatal loss. Furthermore, other studies indicate that UA velocimetry is a predictor of adverse outcomes in pregnancies complicated by oligohydramnios. [8,9] Thus, arterial Doppler velocimetry measurement may be useful in predicting adverse pregnancy outcomes adjunct to other antenatal surveillance tests, especially the AFI. Therefore, the present study will be done to evaluate the comparative assessment of UA ratio and AFI in predicting adverse perinatal outcomes.

Study Overview

Status

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.

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.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 1, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
