The onset, nadir, and recovery of the deceleration usually coincide with the beginning, peak, and ending of the contraction, respectively.11 Early decelerations are nearly always benign and probably indicate head compression, which is a normal part of labor.15, Variable decelerations (Online Figure I), as the name implies, vary in terms of shape, depth, and timing in relationship to uterine contractions, but they are visually apparent, abrupt decreases in FHR.11 The decrease in FHR is at least 15 bpm and has a duration of at least 15 seconds to less than two minutes.11 Characteristics of variable decelerations include rapid descent and recovery, good baseline variability, and accelerations at the onset and at the end of the contraction (i.e., shoulders).11 When they are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions.11 Overall, variable decelerations are usually benign, and their physiologic basis is usually related to cord compression, with subsequent changes in peripheral vascular resistance or oxygenation.15 They occur especially in the second stage of labor, when cord compression is most common.15 Atypical variable decelerations may indicate fetal hypoxemia, with characteristic features that include late onset (in relation to contractions), loss of shoulders, and slow recovery.15. How to Read a CTG | CTG Interpretation | Geeky Medics Healthcare providers may also use continuous external electronic monitoring during labor. Examples of Category II FHR tracings include any of the following: Strongly predictive of normal fetal acidbase status. The average fetal heart rate is between 110 and 160 beats per minute. Most common association w fetal bradycardia? Subtle, shallow late decelerations can be difficult to visualize, but can be detected by holding a straight edge along the baseline. -*sinusoidal pattern*. This fetal heart rate quiz will test your knowledge about fetal decelerations during labor. [10] The first step involves identifying whether there are accelerations or moderate variability. Fetal heart monitoring. 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). can you recognize these strip elements? An elevated heart rate by itself does not make this a Category 3 fetal heart tracing.

All Rights Reserved. Additionally, an Apgar score of less than 7 at five minutes, low cord arterial pH (less than 7.20), and neonatal and maternal hospital stays greater than three days were reduced.22, Tocolytic agents such as terbutaline (formerly Brethine) may be used to transiently stop contractions, with the understanding that administration of these agents improved FHR tracings compared with untreated control groups, but there were no improvements in neonatal outcomes.23 A recent study showed a significant effect of maternal oxygen on increasing fetal oxygen in abnormal FHR patterns.24. Specific FHR tracings are analyzed in a stepwise manner. Questions and Answers 1. -prolonged decel *can be due to umbilical cord prolapse*.

Periodic changes in FHR, as they relate to uterine contractions, are decelerations that are classified as recurrent if they occur with 50 percent or more of contractions in a 20-minute period, and intermittent if they occur with less than 50 percent of contractions.11 The decrease in FHR is calculated from the onset to the nadir of the deceleration. Consider need for expedited delivery (operative vaginal delivery or cesarean delivery). Preterm contractions are usually painful. - 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
