ABSTRACT

If the CTG is suggestive of fetal distress then FBS from the scalp should always be undertaken before proceeding to CS, unless it is technically not possible to do so.

Explain the procedure to the woman and obtain consent.

The cervix must be at least 3 cm dilated and the presenting part should be no more than 2 cm above the plane of the ischial spines.

The patient should be in the left lateral position or in the lithotomy position with a wedge.

At least two samples should be taken on each occasion. After obtaining each sample, ensure haemostasis by applying pressure with a swab on the stab site.

Inform the patient of the result and plan.
