Editor’s comment: Prof. James Drife: How risky is repetitive fetal scalp blood sampling?
Fetal scalp blood sampling (FBS) is performed when concerns are raised by fetal heart rate monitoring. NICE guidance in the UK recommends a obtaining a consultant opinion if FBS is done more than twice. In this Swedish study of 2134 FBSs in 1070 labours, there were no differences in fetal outcome between labours with 1-2 and those with >3 FBSs, though the risk of caesarean section was doubled in the latter group. The authors emphasise that >50% of women with repetitive FBS will be delivered vaginally, and 1/3 of these spontaneously.

Editor’s comment: Prof. James Drife: Predicting de novo postpartum pre-eclampsia
There have been surprisingly few studies of normal blood pressure (BP) during labour. In this French study, automated BP measurements were made on 1435 women who entered labour with no history of previous hypertensive disorder. Labour increased the mean systolic BP from 119 to 135 mmHg and the mean diastolic from 74 to 81 mmHg. Just under 1% of the women developed de novo early postpartum preeclampsia, which was mild in all cases, and was associated with a systolic BP >150 mmHg or a diastolic >91 mmHg.

Editor’s comment: Prof. James Drife: The significance of the isolated single umbilical artery
Single umbilical artery (SUA) is found in 0.2-2.0% of all pregnancies. It is associated with fetal abnormalities and with growth restriction and perinatal mortality. This study from Vienna, having excluded chromosomal and structural abnormalities, compared 136 singleton pregnancies with SUA with 500 pregnancies with a normal 3-vessel cord. Fetuses with SUA had a lower birthweight and were delivered at an earlier gestational age. SUA was associated with an 11-fold increased risk of IUGR and a 5-fold increase in very preterm delivery.
