Why the study?
Evidence regarding the clinical significance of a single sporadic variable deceleration in a reactive non-stress test is scarce, and optimal management has yet to be established.
Does a single sporadic variable deceleration during a reactive NST at term increase the risk for cesarean delivery due to non-reassuring fetal heart rate monitoring?
Population
Singleton term pregnancies at one university-affiliated medical center in 2018
Comparison
Pregnancies with SSD in reactive NST vs matched pregnancies without SSD
Design
Retrospective 1:2 matched case-control study

No increased perinatal risk supports expectant management of SSD; leaves open confirmation via prospective trials.
Does a single sporadic variable deceleration during a reactive NST at term increase the risk for cesarean delivery due to non-reassuring fetal heart rate monitoring?
A single sporadic variable deceleration during a reactive NST in term pregnancies is not associated with an increased risk for adverse perinatal outcomes or cesarean delivery.
Weinberger et al. (2023) studied this question.
