My OB today is recommending weekly NSTs.
From the little research I've done, I've found the following:
"A NST may be performed if:
- You sense that the baby is not moving as frequently as usual
- You are overdue
- There is any reason to suspect that the placenta is not functioning adequately
"If your baby's heart beats faster (at least 15 beats per minute over his resting rate) while he's moving for at least 15 seconds on two separate occasions during a 20-minute span, the result is normal, or "reactive." A normal result means that your baby is probably doing fine for now. Your practitioner may want to repeat the test every week (or more often) until your baby's born.
"If your baby's heart doesn't beat faster while he's moving or your baby doesn't move after about 90 minutes, the result is "nonreactive." A nonreactive result doesn't necessarily mean something is wrong. It just means that the test didn't provide enough information and you may need to take it again in an hour or take other tests such as a biophysical profile or contraction stress test.
"However, a nonreactive result could indicate that your baby isn't getting enough oxygen or that there are problems with the placenta."
And then, the path can lead to [as I suspected...]:
"If your practitioner thinks that your baby's no longer doing well in the womb, she'll probably decide to induce labor."
Aside from the exposure to ultrasound, which I do not want (as DH put it: you don't even want to be monitored during labor, why would you want this now??), I have none of the "risk factors" indicated. But since I am over 40, the OB recommends. My gut feeling is: NONSENSE.
Anyone else faced with this decision? What did you decide, and why?
