[The rectal-digital fetal stimulation test--an alternative to fetal blood analysis?]

The rectal-digital fetal stimulation test (FST) is outlined. The indications of FST are the same as for the fetal scalp, blood sampling (FBA). Our clinical experiences suggested, that the fetal scalp blood sampling rate may be reduced by 50% using FST. The main advantage of the FST is that it can be repeated easily without any increased infection risk.
