Without knowing more, it is hard to say, but generally with ROM I am content to wait longer...one mw I know says her limit is 7days, as long as mom has no fever, baby is doing well and there are otherwise no signs of infection.
Remember that prolonged ROM does not mean that an infection is *inevitable*....just that *more* women/babies get infections after 18-24hrs ROM than women/babies whose ROM happens in active labor/not many hrs before birth. This is what we call a 'risk factor'--since more women/babies experience infection w/ROM after that time period, even though it's not all that many more, it is medically considered a possibility that should be controlled-for through interference such as induction/augmentation/surgery.
To me what is sad is that hosp care providers want moms to come in soon after ROM, with or w/out contrax--but the hospital is the least safe place to go, for people who may be vulnerable to infection! The most virulent superbugs grow in hospitals, AND, while I do no VE with ROM at home, at least until active labor, when VE is far safer in terms of infection risk, in the hospital they freely and sometimes frequently perform VE on ROM moms. Before active labor starts, for every VE done on a ROM mom, the risk of infection is multiplied...so I don't get why anyone would feel safer in the hospital with ROM than at home, waiting and taking good care of self/baby until labor starts or bag reseals.
Being at home and comfortable, keeping all things out of the vagina, using a peri bottle to rinse after bathroom use, use of vit c and/or echinacea to boost immune system, drinking plenty to help replace amniotic fluid, monitoring mom's temp and smell/color of water are some things that can be done to help prevent infection and monitor it's possible onset...and again, the 'risk' of infection is a 'risk', a numbers/statistics thing, NOT a certainty. There are also, we (and drs) seem to forget, risks--even unto life-and-health-threatening risks to both moms and babies--in the use of pitocin and cytotec for induction, and in caesarian surgery also.
I recently had a mom request transport for augmentation after 30hrs ROM (at 40wks + 4days, her 'usual' time of birth). There was no reason for this except "I want this baby out"--which was a perfectly valid reason and so we went--just saying she and baby were both fine and she was also gbs neg. The birth was only 7hrs later after a few hours of pitocin and a few more of natural labor, and all was more or less well (don't get me started on the nursery protocols tho!). But this worried me because I knew all that *could* go wrong for her, and result in surgery or other interventions. I hear these tales all too often--ROM happens and labor doesn't, and the mom and baby are fed into the medical mill based on these presumed risk factors. Too often moms end up with caesarians--mainly because mom is tired...or docs are tired of waiting.
