“…The trial has demonstrated clinically important differences between the performance of the three electrodes. The findings are consistent with the results of previously reported small trials (Calvert & Newcombe 1980; Nickelsen et al 1989). The Surgicraft‐Copeland was significantly least likely to become detached.…”

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.

“…Three types of FSE are currently used in the United Kingdom. The Copeland electrode (Surgicraft Ltd., Redditch, UK), a spring‐loaded clip, is by far the most popular for FHR monitoring because of its ease of use (Calvert & Newcombe 1980) and reliable attachment (Needs et al 1992) as well as being favoured on the grounds of safety (DHSS 1985). However, for the purposes of fetal ECG waveform analysis, signals recorded from single spiral electrodes, such as those produced by Corometrics Medical Systems, Inc. (Wallingford, Connecticut, USA) and Cetro AB (Sweden) appear to be superior to those from the Copeland electrode (Westgate et al 1990).…”

“…This electrode is much less prone to becoming dislodged. Calvert and Newcombe (1980) have also shown that the reusable Copeland electrode is the cheapest to use, provided that it lasts for at least four applications. A third alternative for both sites is the Showell Surgicraft Copeland electrode ( Figure 6), in which a single stainless steel electrode is applied by twisting the stem of the device.…”
