First, the mare has been up at the State University Clinic for almost a week now and is being closely monitored. She showed signs of imminent foaling but we seem to be out of the woods for that right now. She’s at Day 316 today.
Today’s report is the mare is looking good, and her ‘about to foal’ indicators are much reduced. They are very happy with how she’s responding to treatment.
However, the fetus’ heart rate is quite low, and they are worried about that. It’s been 50 or very low 50s for the past 10 days or so. They are concerned about that, but say there’s nothing they can really do, and that the best thing is for the foal to stay in mom for as long as possible, to continue cooking and developing.
I swing back and forth between cautious optimism and concern that we’re going through all this only to have the mare foal something with brain damage or physical issues that result from, or led to, the low heart rate.
Has anyone any stories, good or bad, about low fetal heart rate for prolonged period prior to being born? What would a low heart rate be an indicator of?
