[Prenatal biophysical monitoring: stress tests]

Intrapartum fetal monitoring has provided a method by which the clinician can more accurately determine the status of the fetus during labor. More recently, investigations have been directed toward antepartum FHR monitoring studies to determine fetal well-being prior to the onset of labor. In this study, the results of "stress" monitoring are presented. The Authors have used three types of stress-tests: 1) oxytocin stress test 2) step-test 3) Oxygen stress test. The positive tests appears to correlate meaningfully with intrauterine compromise and neonatal status.
