It is still unknown whether NI\u2010fECG and EHG will eliminate the need for invasive methods, such as the intrauterine pressure catheter and fetal scalp electrode. We studied whether NI\u2010fECG and EHG can be successfully used during labor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>A prospective clinical pilot study was performed in a tertiary care teaching hospital. A total of 50 women were included with a singleton pregnancy with a gestational age between 36<jats:sup>+0<\/jats:sup> and 42<jats:sup>+0<\/jats:sup>\u2009weeks and had an indication for continuous intrapartum monitoring. The primary study outcome was the percentage of women with NI\u2010fECG and EHG monitoring throughout the whole delivery. Secondary study outcomes were reason and timing of a switch to conventional monitoring methods (i.e., tocodynamometry and fetal scalp electrode or doppler ultrasound), repositioning of the abdominal electrode patch, success rates (i.e., the percentage of time with signal output), and obstetric and neonatal outcomes. Clinical trial registration: Dutch trial register (NL8024).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In 45 women (90%), NI\u2010fECG and EHG monitoring was used throughout the whole delivery. In the other five women (10%), there was a switch to conventional methods: in two women because of insufficient registration quality of uterine contractions and in three women because of insufficient registration quality of the fetal heart rate. In three out of five cases, the switch was after full dilation was reached. Repositioning of the abdominal electrode patch occurred in two women. The overall success rate was 94.5%. In 16% (<jats:italic>n<\/jats:italic>\u2009=\u20098) of women, a cesarean delivery was performed due to non\u2010progressing dilation (<jats:italic>n<\/jats:italic>\u2009=\u20097) and due to suspicion of fetal distress (<jats:italic>n<\/jats:italic>\u2009=\u20091). Neonatal metabolic acidosis did not occur. Two neonates (4%) were admitted to the neonatal intensive care unit for complications not related to intrapartum monitoring.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>NI\u2010fECG and EHG can be successfully used during labor in 90% of women.
