Fetal Survillence

Question 1

The use of intrapartum fetal scalp blood sampling (FBS) is ‘associated’ with which of the following?

Answer 1

A lower caesarean section rate

intrapartum scalp sampling is associated with a lower caesarean section rate because it helps to distinguish between the well fetus with an abnormal CTG and the compromised fetus with an abnormal CTG, i.e. it improves specificity.

Question 2

Of the following, which is the most important aspect of intermittent auscultation of the fetal heart rate in active labour?

Answer 2

Auscultation during and for 30 seconds after the contraction

this is a critical component of intermittent auscultation and only this way do you have any chance of picking up more the more subtle and late decelerations

Question 3

According to the RANZCOG Intrapartum Fetal Surveillance Clinical Guideline, of the following, who does not require a CTG in labour?

Answer 3

A woman with diet controlled gestational diabetes, in early labour at 37+1 weeks gestation

neither diet controlled GDM nor 37+1 week gestation are indications for EFM in labour

Question 4

Following the introduction of routine dual vessel umbilical cord blood sampling, which of the following has been observed?

Question 5

In terms of intrapartum fetal surveillance, lactic acid is:

Answer 5

a by-product of anaerobic metabolism

lactic acid is a by-product of anaerobic metabolism, suggesting fetal hypoxaemia
