Continuous intrapartum fetal monitoring: a prospective randomized comparison of 2 types of fetal scalp electrode.
This trial was conducted to compare 2 commonly used fetal scalp electrodes with regard to ease of use, frequency and extent of neonatal injury and quality of cardiotocographic record. A randomized design was employed to study a group of 106 patients divided between a Surgicraft Copeland clip fetal scalp electrode (52 patients) and a Meditrace spiral single helix scalp electrode (54 patients). Patients were eligible for trial entry if they required an intrapartum fetal scalp electrode, at term with a singleton cephalic pregnancy. Ease of application was rated by the operator using a linear analogue score. Unidentified traces were reviewed independently for quality by 2 obstetricians and neonates were examined on day-2 postpartum for injury. The Meditrace spiral fetal scalp electrode was significantly easier to apply (unpaired t-test p < 0.02). It also obtained higher ratings for trace quality (unpaired t-test p < 0.02). There were no serious neonatal injuries and no difference was found between the 2 electrodes in this regard.
