Recent postings have discussed NSTs (non stress tests) and the use of nipple stimulation to elicit the release of oxytocin (pitocin). I think it's important that a clarification be made so that any expectant mothers on line are not under any misconceptions, should their MD suggest an NST. An NST is a screening test which evaluates fetal well being by observing how the fetal heart rate reacts to fetal movement. The healthy, well oxygenated fetal heart should accelerate when the fetus moves. There is no oxytocin or nipple stimulation involved in an NST; that would be an OCT or Oxytocin Challenge Test, which measures the fetus' reaction to contractions. The contractions may be elicited by using nipple stimulation or small doses of IV Pitocin. Have been doing these tests for 7 years now and am often dismayed at the misconceptions and anxiety that many women bring in with them. A simple explanation by the Doc would alleviate alot of the their concerns, and yes, I have shared this opinion with many of them. Thanks for letting me offer my .02 worth. Mary A.
