Management of Term Pregnancy with Non-Reactive NST but Reassuring BPP

Rationale for Delivery

The American College of Radiology recommends delivery at term gestation (38.5 weeks) given abnormal antenatal test results, including non-reactive NST, despite a reassuring BPP of 8/8 1, 2
The ACR Appropriateness Criteria state that a modified BPP with non-reactive NST warrants delivery in term pregnancies, with a strength of evidence based on expert opinion and clinical experience 1, 2

Term gestation status at 38.5 weeks, where delivery carries minimal neonatal risk, supports proceeding with delivery 1, 2
Active labor, with the patient already in labor, makes expectant management impractical and favors delivery 1, 2
Non-reactive NST indicates the fetus is not demonstrating normal heart rate accelerations, which, combined with other concerning features, supports delivery 1, 3

No test, including BPP and NST, can predict acute fetal compromise events such as placental abruption or cord accidents, highlighting the importance of considering all clinical factors 1, 2, 3

Induction of labor is reasonable if there are no other contraindications, but Cesarean delivery may be warranted due to concerns about fetal well-being and potential intolerance of labor, as recommended by the American College of Radiology 1, 2

Continuous electronic fetal monitoring should be initiated immediately given the non-reactive NST and decreased fetal movement, to closely monitor fetal well-being 1, 3
Consider expedited delivery if any additional concerning features develop during labor monitoring, to minimize risk to the fetus 1, 2
A lower threshold for Cesarean delivery is recommended given the combination of non-reactive NST and decreased fetal movement, even with reassuring BPP, to prioritize fetal safety 1, 2

Although the BPP has a high negative predictive value for fetal well-being over the next week, this patient is already at term and in active labor, making continued expectant management unnecessary and potentially risky 1, 2, 4, 5
