The recommendations for the overall management of FHR tracings by NICHD, the International Federation of Gynecology and Obstetrics, and ACOG agree that interpretation is reproducible at the extreme ends of the fetal monitor strip spectrum.10 For example, the presence of a normal baseline rate with FHR accelerations or moderate variability predicts the absence of fetal acidemia.10,11 Bradycardia, absence of variability and accelerations, and presence of recurrent late or variable decelerations may predict current or impending fetal asphyxia.10,11 However, more than 50 percent of fetal strips fall between these two extremes, in which overall recommendations cannot be made reliably.10 In the 2008 revision of the NICHD tracing definitions, a three-category system was adopted: normal (category I), indeterminate (category II), and abnormal (category III).11 Category III tracings need intervention to resolve the abnormal tracing or to move toward expeditious delivery.11 In the ALSO course, using the DR C BRAVADO approach, the FHR tracing may be classified using the stoplight algorithm (Figure 19), which corresponds to the NICHD categories.9,11 Interventions are determined by placing the FHR tracing in the context of the specific clinical situation and corresponding NICHD category, fetal reserve, and imminence of delivery (Table 4).9,11, If the FHR tracing is normal, structured intermittent auscultation or continuous EFM techniques can be employed in a low-risk patient, although reconsideration may be necessary as labor progresses.2 If the FHR tracing is abnormal, interventions such as position changes, maternal oxygenation, and intravenous fluid administration may be used. or call toll-free from U.S.: (800) 762-2264 or (240) 547-2156 Enter your email address below and hit "Submit" to receive free email updates and nursing tips. When continuous EFM tracing is indeterminate, fetal scalp pH sampling or fetal stimulation may be used to assess for the possible presence of fetal acidemia.5 Fetal scalp pH testing is no longer commonly performed in the United States and has been replaced with fetal stimulation or immediate delivery (by operative vaginal delivery or cesarean delivery). -*considered significantly non-reassuring, esp when repetitive and associated w decreased variability*, Repetitive late decelerations are defined as, occurring *after 50%+ of contractions in a 20 min* period, *uteroplacental insufficiency*, as a result of eitehr decreased uterine perfusion or decreased placental function 1. Decelerations represent a decrease in FHR of more than 15 bpm in bandwidth amplitude. What to Know About Epilepsy and Pregnancy. However, FHR with low-quality signals may somehow exaggerate the risk of the fetus suffering from acidemia, thus contributing to an increase in cesarean section rates. Sometimes a fetal heart rate is outside the normal range simply because the fetus is moving around. The baby may need to grow for another week or two before you and your healthcare provider can hear it. - 160-200 generally well tolerated w normal variability, Contraction forces are usually reported as, montevideo units *(MVUs)*: represent *total intensity of each contraction over 10 min* period -*hypertonus*: abnormally high resting tone >25 mmhg or MVU >400 You must know how to identify early decelerations, late decelerations, and variable decelerations.
