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.

Early Decelerations: Everything You Need to Know Compared with structured intermittent auscultation, a period of EFM on maternity unit admission results in a lack of improved neonatal outcomes and increased interventions, including epidural analgesia (NNH = 19), continuous EFM (NNH = 7), and fetal blood scalp testing (NNH = 45). The next step is to identify whether there are significant decelerations present. Low amplitude contractions are not an early sign of preterm labor. -*sinusoidal pattern*. Theyll wrap a pair of belts around your belly. Prolonged decelerations (Online Figures K and L) last longer than two minutes, but less than 10 minutes.11 They may be caused by a number of factors, including head compression (rapid fetal descent), cord compression, or uteroplacental insufficiency. Continuous EFM may adversely affect the labor process and maternal satisfaction by decreasing maternal mobility, physical contact with her partner, and time with the labor nurse compared with structured intermittent auscultation.7 However, continuous EFM is used routinely in North American hospitals, despite a lack of evidence of benefit. This fetal heart rate deceleration quiz will help you learn how to differentiate between early decelerations, late decelerations, and variable decelerations. MedlinePlus.

While it is not always a cause for concern, fetal heart rates outside the normal range may also indicate fetal distress. The perception that structured intermittent auscultation increases medicolegal risk, the lack of hospital staff trained in structured intermittent auscultation, and the economic benefit of continuous EFM from decreased use of nursing staff may promote the use of continuous EFM.8 Online Table A lists considerations in developing an institutional strategy for fetal surveillance.
