Gynaecologist, Obstetrician
Hi,
I'm sorry to hear you were in such a dilemma with your second pregnancy - everyone says the second is meant to be easier! I see your due date has passed - hope it all went well - but I'll provide the information for other readers.
Group B Streptococcus (GBS) is found normally in the vagina in up to 40% of women - only sometimes can it cause infections of the upper genital tract, urinary infections, or neonatal infections.
Some clinicians perform routine swabs of the vagina to check for GBS in pregnancy - some clinicians don't do it at all. The reason is that the risk of neonatal infection is not high and places such as the UK think it is not cost-effective enough to screen all pregnant women. In Australia, the guidelines are basically whatever your obstetrician recommends.
It is interesting that your obgyn recommends a Caesarean section. This is not usually recommended if the only reason is for GBS. Usually, without other reasons, a vaginal delivery is perfectly fine - you just need IV antibiotics for ideally at least 3 hours before the baby is born. Even if your labour is too fast and antibiotics weren't given, your baby would just be monitored more closely and some places give the baby antibiotics in that case.
A Caesarean may not be protective for GBS infection - GBS can still travel up the vaginal through the cervix and into the uterus, especially if your cervix has started to dilate or you have ruptured your membranes.
Hope it all went well.
