The UK National Screening Committee examined the issue of strategies recommended that routine screening using bacteriological culture or near-patient testing techniques should not be introduced into UK practice.

The US Guidelines advise that all pregnant women should be offered screening for GBS carriage at 35–37 weeks of gestation and those found to be colonised with GBS should be offered intrapartum antibiotic prophylaxis.

• If the history suggests that the reaction described is not likely to be allergic in nature then penicillin should be given.
• If the history suggests an allergy to beta-lactams, but one that is not severe(i.e. no anaphylaxis, angioedema, respiratory distress or urticaria), then a cephalosporin can be administered.
• If the allergy to beta-lactams is severe then intravenous vancomycin is recommended.

It is not necessary to administer anti-D Ig to D negative females without childbearing potential, or males who receive D positive platelets.

Women are generally advised to wait for at least 2 years after treatment for breast cancer before
conception.

• No screening test is entirely accurate.
• 17% to 25% of women who have a positive swab at 35–37 weeks of gestation will be GBS negative at delivery.
•  5% to 7% of women who are GBS negative at 35–37 weeks of gestation will be GBS positive at delivery.
• Many of the babies who are severely affected from GBS infection are born prematurely, before the suggested time for screening.

Antenatal treatment for vaginal or rectal colonisation does not reduce the likelihood of GBS colonisation at the time of delivery and so is not indicated in this situation.

IAP should be offered to GBS-colonised women

Up to 10% of women scheduled for ERCS go into labour before
39+0 weeks. Therefore it is good practice to to discuss and document a plan for delivery if labour starts prior to the scheduled date.

A dose of 250 IU anti-D immunoglobulin should be sufficient to cover up to five adult therapeutic doses of D positive platelets given within a 6-week period.

In severely thrombocytopenic patients with platelet count of?30 × 10^9/L, anti-D Ig should be given subcutaneously, or IV.

GBS is present in the bowel flora of 20–40% of adults (this is called ‘colonisation’). People who are colonised are called
‘carriers’. This includes pregnant women (there is no evidence that its carriage rate is specifically affected by pregnancy).

Systemic chemotherapy is contraindicated in the first trimester because of a high rate of fetal
abnormality,but is safe from the second trimester.

The RAADP scheme should be regarded as supplementary to any anti-D Ig administered for sensitising episodes.

For potentially sensitising events after 20weeks gestation,
a minimum anti-D Ig dose of 500 IU should be administered within 72 h of the event.

The recommended dose is - 3 g intravenous benzylpenicillin be given as soon as possible after the onset of labour  and 1.5 g 4 hourly until delivery.
The first dose should be given at least 4 hours prior to delivery.
