Health care professionals play the game to hone and test their EFM knowledge and skills. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. A meta-analysis showed that if there is absent or minimal variability without spontaneous accelerations, the presence of an acceleration after scalp stimulation or fetal acoustic stimulation indicates that the fetal pH is at least 7.20.19, If the FHR tracing remains abnormal, these tests may need to be performed periodically, and consideration of emergent cesarean or operative vaginal delivery is usually recommended.15 Measurements of cord blood gases are generally recommended after any delivery for abnormal FHR tracing because evidence of metabolic acidosis (cord pH less than 7.00 or base deficit greater than 12 mmol per L) is one of the four essential criteria for determining an acute intrapartum hypoxic event sufficient to cause cerebral palsy.20, When using continuous EFM, tracings should be reviewed by physicians and labor and delivery nurses on a regular basis during labor. -absent baseline variability not accompanied by recurrent decels Itis called fetal tachycardia when it is greater than 180 BPM. According to an executive from Vitalant, the largest nonprofit blood bank in the United States, as much as 80% of the blood supply is from vaccinated donors.

", "The Second Look files are phenomenal and were an excellent way to test my knowledge after I had studied a bit.". 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. Category III tracings are associated with fetal acidemia, cerebral palsy and encephalopathy and require expedient intervention If intrauterine resuscitation (eg. If you have any feedback on our Countdown to Intern Year series, please reach out to Samhita Nelamangala at [emailprotected] EFM Tracing Game. 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 fetal heart tracing indicates multiple variable decelerations. Monique Rainford, MD, isboard-certified in obstetrics-gynecology, and currently serves as an Assistant Clinical Professor at Yale Medicine.

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). https://www.acog.org/Patients/FAQs/Fetal-Heart-Rate-Monitoring-During-Labor?IsMobileSet=false BJOG: An International Journal of Obstetrics & Gynaecology. . Yes, and the strip is reactive. -*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 Your doctor conducts intrapartum monitoring of fetal heart rate to pinpoint unusual patterns resulting from an inadequate supply of oxygen. Fetal heart tracing is also useful for eliminating unnecessary treatments. This is done to ensure that the baby is healthy and growing normally.

Injection Gone Wrong: Can You Spot The Mistakes? 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. Absent. Tapping "Update" will cause the slide decks to be updated. The workshop introduced a new classification scheme for decision making with regard to tracings. 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.

Strongly predictive of normal acid-base status at the time of observation. Fetal heart rate (FHR) Top line on monitor strip Uterine contractions Bottom line on monitor strip 8 Features to Describe Baseline Variability Accelerations Decelerations Trends over time Interpret into 1 of 3 categories 9 Baseline Mean fetal heart rate Rounded to increments of 5 During a 10 minute period Excluding accelerations and decelerations Most external monitors use a Doppler device with computerized logic to interpret and count the Doppler signals. The fetal heart rate and contraction information appear on an attached computer screen. Contractions cause an increase in uterine venous pressure and a decrease in uterine artery perfusion. E Jauniaux, F Prefumo. These segments help establish an estimated baseline (for a duration of 10 minutes) which is expressed in beats per minute.
