“…Spiral electrodes which may be a single helix (for example, the Corometrics electrode), or double helix (for example, the Rolon electrode manufactured by Rocket, and the Hewlett‐Packard electrode), are applied with an applicator and attached by a screwing action. The Surgicraft‐Copeland electrode has a skin clip on a small disc (Ghosh & Tipton 1976). The clip is spring‐loaded in a closed position but once the disc is apposed to the fetal scalp the clip can be opened by twisting the body of the electrode and then released to secure attachment.…”

Objectives To compare three scalp electrodes in respect of need for reapplication, trace quality and scalp trauma. Design Randomized controlled trial. Setting Maternity Unit, Royal Berkshire Hospital, Reading. Participants 780 women in labour at term, with cephalic fetal presentation, deemed to require electronic fetal heart rate monitoring using a scalp electrode. Interventions Three types of fetal scalp electrode: Rocket‐Rolon (double‐helix spiral); Hewlett‐Packard (double‐helix spiral); and Surgicraft‐Copeland (clip). Main outcome measures Need for more than one electrode; reason for replacement; trace quality; scalp trauma; direct financial costs. Results Reapplication was significantly least likely in the Surgicraft‐Copeland group (odds ratio vs Hewlett‐Packard = 0.61, 95% CI 0.41–0.90; odds ratio vs Rocket‐Rolon = 0.43, 95% CI = 0.29.0.62). This reflected a much lower rate of replacement because of detachment. The Hewlett‐Packard was, however, least likely to be replaced because of poor trace quality. Interpretable traces were equally common, but trace quality tended to be superior in the Hewlett‐Packard group. There was no serious scalp trauma. Difficulty removing the electrode was least often reported in the Hewlett‐Packard group, and a mark on the scalp persisted least often in the Rocket‐Rolon group. Conclusions The Surgicraft‐Copeland performed the best overall, and particularly in respect of attachment to the scalp. It appears to be the electrode of choice of the three tested.

“…The spiral electrode employs either 1 or 2 short stainless steel wires in a helical configuration and was introduced in the early 1970's replacing the silver-silver chloride electrode. The MSFSE uses only 1 wire The SCFSE was introduced in 1973 and relies on 'a round bodied needle which is totally retractable into a base by a spring attachment' (5). The SCFSE is available in both single use and multiple use styles but only the single use unit was studied in this trial.…”

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.
