Stillbirth after nonstress testing.

V A Barss, F D Frigoletto, F Diamond

Obstetrics and Gynecology

|April 1, 1985

Summary

This summary is machine-generated.

A reactive nonstress test (NST) showed similar stillbirth rates in postdates and high-risk pregnancies. Early stillbirths occurred in postdates pregnancies, with unclear causes, suggesting improved surveillance is needed.

Area of Science:

Perinatal Medicine
Obstetrics
Fetal Monitoring

Background:

The nonstress test (NST) is a common method for fetal surveillance.
Its reliability in postdates and general high-risk pregnancies requires evaluation.
Stillbirth remains a significant concern in high-risk pregnancies.

Purpose of the Study:

To assess the reliability of a reactive nonstress test (NST) in predicting stillbirth.
To compare stillbirth rates in postdates versus general high-risk pregnancies following a reactive NST.
To identify potential improvements in fetal surveillance strategies.

Main Methods:

Retrospective review of patient data.
Analysis of stillbirths occurring within one week of a reactive NST.

Comparison of corrected stillbirth rates between postdates and high-risk groups.

Main Results:

Corrected stillbirth rates were comparable between postdates and general high-risk groups.
33% of stillbirths in postdates patients occurred at or after 41.5 weeks' gestation.
Causes of stillbirth were often unclear in postdates pregnancies; acute events predominated in the high-risk group.

Conclusions:

A reactive NST may have limitations in predicting stillbirth in both postdates and high-risk pregnancies.
Earlier induction or enhanced fetal surveillance beyond weekly NSTs warrants investigation for postdates pregnancies.
Further research is needed to optimize management strategies for high-risk pregnancies.
