Risk factors for nonreassuring fetal heart rate tracings after artificial rupture of membranes in spontaneous labor

Abstract

Nonreassuring FHR after AROM during delivery is associated with parity, fetal station at AROM, birthweight, and oxytocin augmentation.

Proportion and Associated Factors of Nonreassuring Fetal Heart Rate Patterns in Finote Selam Primary Hospital, North West Ethiopia

“…On the other hand, this finding contrasts with the case control study conducted in Israel [ 21 ] where being primigravida decreased the risk of developing NRFHRP. This might be due to proper ANC counselling as many of the participants in the Israel study had ANC follow-up.…”

“…Mothers who had augmentation of labor were 3 times more likely to develop NRFHRP than mothers who had no augmentation. In a similar manner, a study conducted in Israel showed that oxytocin augmentation significantly increased the risk for NRFHRP [ 21 ]. The administration of oxytocin to correct uncoordinated labor patterns confers a risk for increase in uterine contraction frequency and decrement of uterine blood flow which causes hypoxemia and disturbs the FHR pattern [ 22 ].…”

“…These days, NRFHRP has become the most common indication for operative deliveries and a signal of morbidities requiring admission to the neonatal intensive care unit which adds extra burden on our society [ 7 , 8 ]. Studies done across the world revealed that prevalence of NRFHRP ranges between 9.9 and 30.7% [ 6 , 9 – 12 ], and antepartum haemorrhage, intrauterine growth restriction, amniotic fluid disorders, maternal medical illnesses, induction/augmentation of labor, use of anaesthesia, and presence of meconium-stained amniotic fluid were some of the risk factors identified to have association with NRFHRP [ 10 , 12 – 16 ].…”

Magnitude, Associated Factors and Immediate Outcomes of Non-Reassuring Fetal Heart Rate Status Among Laboring Mothers at South Gondar Zone Public Hospitals, North, West Ethiopia, 2022; Cross Sectional Study

“…Many medical and obstetrics factors like antepartum haemorrhage (APH), amniotic fluid disorders, induction/augmentation of labor, intrauterine growth restriction (IUGR), use of anesthesia, presence of MSAF, abnormal fetal presentation and intraoperative findings like (uterine rupture, cord entanglements or placental abruption were the risk factors identified to have association with NRFHS (10, 20, 21).…”

“…NRFHRS tracing was described as requiring necessitates immediate intervention like caesarean section or instrumental vaginal delivery (11, 21), intrauterine resuscitation, including oxytocin deprivation and amnioinfusion (20) to prevent or reduce bad neonatal outcome. But determining the most effective strategy in the case of abnormal FHR tracings is so difficult.…”
