The average gestational age of the fetuses was only 30 weeks, presumably of a young enough age so that infection would be a real threat to them. From this study, it would seem that, if anything, antibiotic treatment might have a negative effect on the infant. She also recommends amniocentesis, ultrasound and the nonstress test to assess fetal maturity and well-being. From personal experience, I can say that ultrasound for this purpose is useless. Well, he must have grown quickly because the next day his actual birth weight was 6lb.
Amniocentesis is dangerous to the fetus and the nonstress test is notoriously undependable.
In short, it seems most advisable to follow the advice of Korte and Scaer. In the case of the former, she is apt to tell the woman to be patient, and to monitor her temperature to be on the lookout for infection. On the other hand, MDs do not usually make such a distinction. I wish I could say that my experience was unusual, but I have talked to other women in different parts of the country with similar experiences. Since PROM is fairly common, occurring in one out of ten pregnancies, it is important not to panic if it happens to you.
