I am an obstetrician here and North Carolina and would consider myself open to most alternative options to medical care in general and perinatal care in particular. I am pleased that several of the individuals posting here have had safe, albeit in my opinion lucky, birth experiences in which they chose to decline recommended medications. To address one question, the legal requirement (and as a law it can be and has been enforced without parental consent) for erythromycin eye ointment (not drops) is to address gonococcal conjunctivitis, an extremely severe condition. It has moderate activity against the milder Chlamydial version. It also has strong efficacy against Staphylococcal species-associated conjunctivitis, most notably S. aureus. So yes, it has intended effect against non-STI etiologies of ophthalmia neonatorum. But keep in mind that infectious status changes not infrequently, despite testing. Negative tests are not 100% sensitive for GC or Chlamydia, and they don't help if an exposure occurs after the testing. Similarly, testing a mom when she delivers is helpful for treatment purposes, but not prevention. Just a thought.
As to the Vitamin K, it is not mandated but is strongly encouraged. To clarify an inaccurate point earlier, Vitamin K deficiency issues are GREATEST in breast-fed babies, not better in them. Oral Vitamin K is not a sufficient substitute when given to the baby (based on current data, although there are some European studies a better regimen now) for the prevention of Late VKDB (2-12 weeks of life); and mom should NEVER take Vitamin K supplements to increase her breast milk concentration. Vitamin K is the key component to most clotting factors and I have seen this lead to maternal death prior to delivery due to pulmonary embolus. Similarly, Vitamin K does not simply protect a baby who is injured. Low vitamin K levels can lead to spontaneous intracranial hemorrhage, disability, and death. (We see this in adults on Coumadin when there levels fluctuate; it is why adults require such close monitoring when on Coumadin). This is not meant to scare, but simply to explain and accurately reflect the data.
Finally, remember that the "your body, your baby" is not a universal protection. Parents actually lose a great deal of say in the medical care of their children in certain situations. Emergencies (including those at or near the time of delivery) are a key example where a physician/nurse/hospital can ignore or override a parent's choice if it is deemed at that time to be outside the safest interest of the minor (example: blood transfusions). Once the baby is outside of your body, it is no longer a simple "your body" decision. Also, be VERY careful of home births; they are illegal without a licensed provider present (and "professional" midwives are not licensed in the state of NC) and are ruled as felonies. This is a topic that is actually prosecuted pretty severely here in NC. Any death that occurs in the comission of a felony is automatically considered 2nd Degree murder, or greater, and parents who knowingly participate in home births (i.e. intent) are charged as accessories to the murder. There are multiple murder cases going on in the state for this very topic. Again, I don't mean for this to sound threatening but want to make all people aware of the implications of the decisions which they are making. And go easy on the Labor and Delivery nurse who posted. While I agree her tone was somewhat adversarial, I understand the frustration that she feels. We go into this profession because we want to help care for people, and unfortunately these "scare stories" are very real. Bad outcomes are fortunately pretty rare in modern medicine, but they still occur and are that much harder to deal with when they occur in the setting where something could have (perhaps should have) been done to prevent them. OK, done preaching.
