Any written information on the tracing (e.g., emergent situations during labor) should coincide with these automated processes to minimize litigation risk.21, Table 5 lists intrauterine resuscitation interventions for abnormal EFM tracings.9 Management will depend on assessment of the risk of hypoxia and the ability to effect a rapid delivery, when necessary. Marked. Assessment of heart rate variability (HRV) is a sensitive indicator of autonomic nervous system function and is used in numerous fields of clinical medicine, including cardiology, neurology, and anesthesiology. Low amplitude contractions are not an early sign of preterm labor. 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. Contractions cause an increase in uterine venous pressure and a decrease in uterine artery perfusion. What reassuring sign is missing? Your obstetrician reviews the fetal heart tracing at regular time intervals. < 32 weeks EGA: peak 10 bpm above baseline, duration 10 seconds but < 2 minutes from onset of the acceleration to return to baseline. Whenever possible, they will implement measures to prevent an unfavorable outcome. 1.

UT Southwestern Medical Center. Structured intermittent auscultation is a technique that employs the systematic use of a Doppler assessment of fetal heart rate (FHR) during labor at defined timed intervals (Table 1).4 It is equivalent to continuous EFM in screening for fetal compromise in low-risk patients.2,3,5 Safety in using structured intermittent auscultation is based on a nurse-to-patient ratio of 1:1 and an established technique for intermittent auscultation for each institution.4 Continuous EFM should be used when there are abnormalities in structured intermittent auscultation or for high-risk patients (Table 2).4 An admission tracing of electronic FHR in low-risk pregnancy increases intervention without improved neonatal outcomes, and routine admission tracings should not be used to determine monitoring technique.6. Intraobserver variability may play a major role in its interpretation. Please try reloading page. Category II : Indeterminate. 2 ): a convolutional neural network (CNN) that captures the salient characteristics from ultrasound input images; a convolution gated recurrent unit (C-GRU) [ 16] that exploits the temporal coherence through the sequence; and a regularized loss function, called -variable decels w no other characteristics, -*absent baseline variability and any of following*: Dr. Maya Hammoud is Professor and Associate Chair for e-Learning and Enabling Technologies in the Departments of Obstetrics and Gynecology and of Learning Health Sciences at the University of Michigan Medical School.

Typically performed in the later stages of pregnancy and during labor, fetal heart tracing results can say a lot about the health of your baby. 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. Electronic fetal monitoring is performed in a hospital or doctors office. Content adapted from relevant ACOG Practice Bulletins and AAFP Guidelines. DR C BRAVADO incorporates maternal and fetal risk factors (DR = determine risk), contractions (C), the fetal monitor strip (BRA = baseline rate, V = variability, A = accelerations, and D = decelerations), and interpretation (O = overall assessment). Your doctor conducts intrapartum monitoring of fetal heart rate to pinpoint unusual patterns resulting from an inadequate supply of oxygen. 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. The Fetal Heart Rate Tracing SecondLookTM application is a study aid for learners of the medical professions (specifically Ob/Gyn, nursing and midwifery) to self-test their level of knowledge about this important diagnostic procedure widely used in pre-natal care. On the NCLEX exam and in your maternity OB nursing lecture classes, you will have to know how to identify each fetal heart rate tone deceleration. Internal FHR monitoring is accom-plished with a fetal electrode, which is a spiral wire placed directly on the fetal scalp or other presenting part. Correct. Our proposed deep learning solution consists of three main components (see Fig. This is done to ensure that the baby is healthy and growing normally. The electronic fetal monitor uses an external pressure transducer or an intrauterine pressure catheter (IUPC) to measure amplitude and frequency of contractions. -first stool is meconium, but fetus can pass meconium in utero, which is a sign of fetal stress It was conceived with learners in mind, who want to self-evaluate and review their knowledge of this widely-used diagnostic procedure for quizzes or examinations, as well as its use in patient care.

Ectopic Pregnancy Quiz Questions And Answers. Detection is most accurate with a direct fetal scalp electrode, although newer external transducers have improved the ability to detect variability. 1. A concern with continuous EFM is the lack of standardization in the FHR tracing interpretation.5,811 Studies demonstrate poor inter-rater reliability of experts, even in controlled research settings.12,13 A National Institute of Child Health and Human Development (NICHD) research planning workshop was convened in 1997 to standardize definitions for interpretation of EFM tracing.14 These definitions were adopted by the American College of Obstetricians and Gynecologists (ACOG) in 2002,5 and revisions were made in a 2008 workshop sponsored by NICHD, ACOG, and the Society for Maternal-Fetal Medicine.11 The Advanced Life Support in Obstetrics (ALSO) curriculum developed the mnemonic DR C BRAVADO (Table 3) to teach a systematic, structured approach to continuous EFM interpretation that incorporates the NICHD definitions.9,11.

Dr. Hammoud has dedicated her career to medical student education and serves in many educational leadership roles locally and nationally. Variability (V; Online Table B). ", "The Second Look was a fantastic review for the exam, for both structure and function. Continuous EFM reduced neonatal seizures (NNT = 661), but not the occurrence of cerebral palsy. Conversely, hearing a fetal heart rate by home Doppler in certain situations may provide a false sense of security when medical attention is actually needed. Palpate the abdomen to determine the position of the fetus (Leopold maneuvers) 2. 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. It means your fetus is neurologically responsive and doesnt have an oxygen deficiency. When the healthcare team detects a possible problem, their first step will be to try to find the cause. Sarah BSN, RN explains in this video tutorial some clever ways on how to learn these type of fetal heart rate decelerations. While handheld fetal Dopplers are available over the counter, it is best to consult your healthcare provider before using one. -amnioinfusion can treat it in cases of oligohydramnios or when ROM has occurred to decrease rate of decels and C-sections, Recurrent decel (variable, early, late) defined as, decels occuring w >50% of uterine contractions in any 20 min segment, decrease in FHR >15 bpm measured from most recently determined baseline rate, *lasting >2 min, but <10 min* This web game uses NICHD terminology to identify tracing elements and categorize EFM tracings.
