There is currently a shortage of fetal scalp electrodes because of a recent recall due to concerns about the breakage of the electrode tip with possible injury to the neonate. Although the recall is presumably intended to improve safety, the resulting shortage of fetal scalp electrodes poses risks to patients because of inadequate fetal heart rate monitoring in cases where an adequate signal cannot be obtained with external fetal monitoring and/or when maternal heart rate artifact cannot be resolved by repositioning of transducers and application of a maternal pulse oximeter.
目前，由于最近一次召回，胎儿头皮电极出现短缺，原因是担心电极尖端断裂，可能对新生儿造成伤害。尽管召回的目的想必是为了提高安全性，但由于在无法通过外部胎儿监测获得足够信号的情况下，以及在重新定位传感器和应用母体脉搏血氧仪无法解决母体心率伪影的情况下，胎儿心率监测不充分，导致胎儿头皮电极短缺对患者构成了风险。
