การประเมินสุขภาพทารกในครรภ์ระยะก่อนคลอด โดยการกระตุ้นทารกด้วยมือ

บทคัดย่อ

          A Study about accuracy of antepartum screening test with manual fetal manipulation. One hundred and ten high risk singleton pregnancies (211 occasion) attending High Risk Clinic at Prachuab-khirikhan Hospital with at least 34 weeks gestation were recruited in this study. Using two techniques in each case, first with manual fetal manipulation and record fetal heart sound before and after, second with Nonstress test. The study found that fetal heart rate acceleration from manual fetal manipulation test, using 10 bpm out off point, had sensitivity 80%, specificity 89%, positive predictive value 43.24%, negative predictive value 97.70% and accuracy 88.15% when using Nonstress test as a Gold Standard. The finding suggested that fetal heart rate acceleration along with manual fetal manipulation may be used as a screening test in antepartum clinic. This test is simple and rapid method can be used in antenatal clinic where fetal monitoring is not available. But when test is positive, further investigation is recommended.
