Intrapartum electronic fetal monitoring in the non-reassuring fetal state
(Universidad Privada Norbert Wiener, 2021-03-10) Mejía Quiroz, Zenia Rosa; Ayala Peralta, Félix Dasio
Materials and Methods: Bibliographic searches were conducted in 12 selected databases. Results: Among the reviewed studies, there were 21 original articles, 6 theses, and 3 systematic reviews. Most studies focused on term pregnancies in labor without previous pathologies and/or complications, except for 6 studies. The cardiotocographic patterns (MEFI) associated with non-reassuring fetal status included baseline tachycardia, bradycardia, unstable baseline, absence of accelerations, repeated late decelerations, prolonged decelerations, absence of fetal cycles, and marked, reduced, or absent variability. In 7 studies, the presence of accelerations or moderate variability was associated with preserved fetal well-being. In 2 studies, a higher incidence of cerebral palsy was observed, one of which was linked to a major obstetric complication. In 2 studies, there was an impact on perinatal mortality, but one was associated with an obstetric emergency. Conclusion: Most reviewed studies highlight the importance of intrapartum cardiotocographic tracing for detecting the onset of fetal hypoxia. Intrapartum fetal monitoring is a sensitive indicator for identifying fetuses with reassuring fetal status. MEFI does not have a significant impact on the prevention of cerebral palsy and mortality.
