Intrapartum category I, II, and III fetal heart rate tracings: Management contraction. Late. An increase in risk status during labor, such as the diagnosis of chorioamnionitis, may necessitate a change in monitoring from structured intermittent auscultation to continuous EFM. Sometimes, a fetal heart rate is abnormal because of something happening in the mothers body. 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. A prenatal non-stress test (NST) can be used to assess fetal heart rate and movement at around 26 to 28 weeks of gestation.
Fetal Heart Tracing Flashcards | Quizlet Coussons-Read ME. Your doctor conducts intrapartum monitoring of fetal heart rate to pinpoint unusual patterns resulting from an inadequate supply of oxygen. Differentiate maternal pulse from fetal pulse, 4. This article reviews normal fetal heart rate, how it is measured, who should monitor it, and what causes variations. The baseline when the woman's abdomen is relaxed will be from zero to 10. ", "The Second Look files are phenomenal and were an excellent way to test my knowledge after I had studied a bit.". ____ Variable C.)> 15 bpm below basline for However, extensive use at home could lead to unanticipated negative consequences. FHR baseline usually ranges from 120-160 beats per minute (bpm); however, with fetal decelerations, the heart rate usually drops about 40bpm below baseline. Write a program that checks whether a sequence of HTML tags is properly nested. -early labor: 0-6cm, 6-12 hours Quiz, Chapter 24: Adolescent Sexual Activity and Teenage Pregnancy. The EFM toolkit also offers EFM CE opportunities and C-EFM(R) certification information. While EFM use may be common and widespread, there is controversy about its efficacy, interobserver and intraobserver variability, and management algorithms. Your JFAC wishes you the best of luck as you start this rewarding journey.
None. . Fetal heart rate is a term that refers to a baby's heartbeat while they're in the uterus. ", "The Second Look was a fantastic review for the exam, for both structure and function. American Pregnancy Association. The NCC EFM Tracing Game is just one of the valuable tools in this digital EFM toolkit. Category I FHR includes all of the following: baseline: 110-160 bpm Fetal heart tracing allows your doctor to measure the rate and rhythm of your little ones heartbeat. Detection is most accurate with a direct fetal scalp electrode, although newer external transducers have improved the ability to detect variability. The periodic review includes ensuring that a good quality tracing is present and that abnormalities are appropriately communicated. Count FHR after uterine contraction for 60 seconds (at 5-second intervals) to identify fetal response to active labor (this may be subject to local protocols), Abnormal umbilical artery Doppler velocimetry, Maternal motor vehicle collision or trauma, Abnormal fetal heart rate on auscultation or admission, Intrauterine infection or chorioamnionitis, Post-term pregnancy (> 42 weeks' gestation), Prolonged membrane rupture > 24 hours at term, Regional analgesia, particularly after initial bolus and after top-ups (continuous electronic fetal monitoring is not required with mobile or continuous-infusion epidurals), High, medium, or low risk (i.e., risk in terms of the clinical situation), Rate, rhythm, frequency, duration, intensity, and resting tone, Bradycardia (< 110 bpm), normal (110 to 160 bpm), or tachycardia (> 160 bpm); rising baseline, Reflects central nervous system activity: absent, minimal, moderate, or marked, Rises from the baseline of 15 bpm, lasting 15 seconds, Absent, early, variable, late, or prolonged, Assessment includes implementing an appropriate management plan, Visually apparent, abrupt (onset to peak < 30 seconds) increase in FHR from the most recently calculated baseline, Peak 15 bpm above baseline, duration 15 seconds, but < 2 minutes from onset to return to baseline; before 32 weeks gestation: peak 10 bpm above baseline, duration 10 seconds, Approximate mean FHR rounded to increments of 5 bpm during a 10-minute segment, excluding periodic or episodic changes, periods of marked variability, and segments of baseline that differ by > 25 bpm, In any 10-minute window, the minimum baseline duration must be 2 minutes, or the baseline for that period is indeterminate (refer to the previous 10-minute segment for determination of baseline), The nadir of the deceleration occurs at the same time as the peak of the contraction, The nadir of the deceleration occurs after the peak of the contraction, Abrupt decrease in FHR; if the nadir of the deceleration is 30 seconds, it cannot be considered a variable deceleration, Moderate baseline FHR variability, late or variable decelerations absent, accelerations present or absent, and normal baseline FHR (110 to 160 bpm), Continue current monitoring method (SIA or continuous EFM), Baseline FHR changes (bradycardia [< 110 bpm] not accompanied by absent baseline variability, or tachycardia [> 160 bpm]), Tachycardia: medication, maternal anxiety, infection, fever, Bradycardia: rupture of membranes, occipitoposterior position, post-term pregnancy, congenital anomalies, Consider expedited delivery if abnormalities persist, Change in FHR variability (absent and not accompanied by decelerations; minimal; or marked), Medications; sleep cycle; change in monitoring technique; possible fetal hypoxia or acidemia, Change monitoring method (internal monitoring if doing continuous EFM, or EFM if doing SIA), No FHR accelerations after fetal stimulation, FHR decelerations without absent variability, Late: possible uteroplacental insufficiency; epidural hypotension; tachysystole, Absent baseline FHR variability with recurrent decelerations (variable or late) and/or bradycardia, Uteroplacental insufficiency; fetal hypoxia or acidemia, 2. A way to assess your babys overall health, fetal heart tracing is performed before and during the process of labor. Accelerations (A). It means your fetus is neurologically responsive and doesnt have an oxygen deficiency.

After speaking directly with the physician, the next person in the chain of command you should communicate with is, The best placement for the tocodynamometer to pick up uterine contractions is the, When using a fetal scalp electrode (FSE) you notice an abnormally low FHR on the monitor. What Do Braxton Hicks Contractions Feel Like? if accel is 10 min+, it is a baseline change, 15 bpm above baseline w duration of 15 sec or more but less than 2 min. The use of amnioinfusion for recurrent deep variable decelerations demonstrated reductions in decelerations and cesarean delivery overall. Discontinue oxytocin (Pitocin) infusion, if in use, 4. NCC EFM Tracing Game. 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. Dr. Hammoud has dedicated her career to medical student education and serves in many educational leadership roles locally and nationally. 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.

Any type of abnormality spotted in a fetal heart tracing could indicate an inadequate supply of oxygen or other medical issues. Fetal Heart Rate Monitoring - Freeman 2012 "Fetal heart rate monitoring is widely used by almost every obstetrician as a way to document the case and to help decrease health care costs. Print Worksheet. This mobile app covers the following topics: Basics of reading and evaluating fetal heart rate tracings, including baseline determination and variability; the evaluation and biological background of various types of accelerations and decelerations; and a set with case examples for practicing the interpretation of FHR tracings. a. As a result of the intrinsic fetal response to oxygen deprivation, increased catecholamine levels cause the peripheral blood flow to decrease while the blood flows to vital organs increases. 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). Impact of maternal exercise during pregnancy on offspring chronic disease susceptibility. 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 term hyperstimulation is no longer accepted, and this terminology should be abandoned.11. This is most likely to be done in the late stages of your pregnancy and it might be combined with other tests to see if you have either diabetes or high blood pressure both of which can cause problems. Abnormal fetal acidbase status cannot be ruled out. Another area of interest is the use of computer analysis for key components of the fetal tracing,29 or decision analysis for the interpretation of the EFM tracing.30 These have not been demonstrated to improve clinical outcomes.29,30 Fetal pulse oximetry was developed to continuously monitor fetal oxygenation during labor by using an internal monitor, requiring rupture of membranes.31 Trials have not demonstrated a reduction in cesarean delivery rates or interventions with the use of fetal pulse oximetry.31. Continuous monitoring of your babys heart rate is conducted during labor and delivery as well. While it can be an important tool to assess fetal wellbeing, it is also limited by its high false-positive rate. early decels present or absent *moderate baseline variability* FHR: fetal heart rate; bpm: beats per minute. Continuous electronic fetal monitoring was developed in the 1960s to assist in the diagnosis of fetal hypoxia during labor. 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. > 2 min., but < 10 min in Understanding the physiology of fetal oxygenation and various influences on fetal heart rate control supports nurses, midwives, and physicians in interpreting and managing electronic fetal heart rate tracings during labor and birth.

Auscultation of the fetal heart rate (FHR) is performed by external or internal means.
Real-time diameter of the fetal aorta from ultrasound Healthcare providers monitor fetal heart rate during labor to watch how the baby responds to contractions, medications, tests, and pushing. *nonreflex*: greater degree of relative hypoxemia and result in hypoxic depression of myocardium coupled w vagal response The resulting printout is known as a fetal heart tracing, which will be read and analyzed. 409 12th Street SW, Washington, DC 20024-2188, Privacy Statement When using external fetal heart monitoring, the fetal heart rate is generally best found by placing the monitor over the fetal _____. Ayres-de-Campos D, Spong C, Chandraharan E. FIGO consensus guidelines on intrapartum fetal monitoring: Cardiotocography. Continuous electronic fetal monitoring (EFM), using external or internal transducers, became a part of routine maternity care during the 1970s; by 2002, about 85 percent of live births (3.4 million out of 4 million) were monitored by it.1 Continuous EFM has led to an increase in cesarean delivery and instrumental vaginal births; however, the incidences of neonatal mortality and cerebral palsy have not fallen, and a decrease in neonatal seizures is the only demonstrable benefit.2 The potential benefits and risks of continuous EFM and structured intermittent auscultation should be discussed during prenatal care and labor, and a decision reached by the pregnant woman and her physician, with the understanding that if intrapartum clinical situations warrant, continuous EFM may be recommended.3, There are several considerations when choosing a method of intrapartum fetal monitoring. . The Fetal Heart Rate Tracing SecondLookTM app consists of three slide sets, which cover the basic interpretation of FHR tracings including the determination of baseline and variability, various types of acceleration and decelerations, and some examples and practice cases. Nadir of the deceleration = peak of the contraction. It provides more precise readings that are not affected by the babys movement. Health care professionals play the game to hone and test their EFM knowledge and skills.
