early decels present or absent It's typically the first time they hear their babys heartbeat during a prenatal visit. Fetal heart rate is a term that refers to a baby's heartbeat while they're in the uterus. Healthcare providers may also use continuous external electronic monitoring during labor. Fluorescent-labeled lineage tracing revealed that 1 week after transplantation, green fluorescent protein (GFP)-MSCs were found to migrate to the bone surface (BS) in control mice but not in DIO mice. Adequate documentation is necessary, and many institutions are now employing flow sheets (e.g., partograms), clinical pathways, or FHR tracing archival processes (in electronic records). Minimal. The main goal is to identify fetuses who are prone to injuries stemming from hypoxia (or a lack of oxygen for fetal tissues). The average fetal heart rate varies depending on the stage of pregnancy. These flow changes along with increased catecholamine secretions have what effect on fetal blood pressure and fetal heart rate?

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. A fetal heart rate gives you and your healthcare team information about your baby's health during pregnancy. A fetal heart rate greater than 160 beats per minute (BPM) is considered fast. 32 weeks EGA: peak 15 bpm above baseline, duration 15 seconds but < 2 minutes from onset of the acceleration to return to baseline. While it is not always a cause for concern, fetal heart rates outside the normal range may also indicate fetal distress. Continuous EFM increased cesarean delivery rates overall (NNH = 20) and instrumental vaginal births (NNH = 33). How can you tell if a fetus is in distress? -*associated w decreased or absent FHR variability*, 110-160 bpm The interpretation of the fetal heart rate tracing should follow a systematic approach with a full qualitative and quantitative description.

Mild to moderate heart rate changes in otherwise healthy women generally do not negatively affect the babys heart rate. Give intravenous fluids if not already administered; consider bolus, 7. Strongly predictive of normal acid-base status at the time of observation. The fetal heart rate acts as a screening tool for the healthcare team. 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 Second Look was a fantastic review for the exam, for both structure and function.

I actually went over the Second Look (files) twice - once immediately after doing the lecture and lab to help reinforce what I learned, and then again before the exam as a review. *reflex late decels*: thought to be in response to vagal stimulation by chemoreceptors in fetal head in response to low oxygen What does it mean to have a "reactive strip"? Continuous electronic fetal monitoring has been shown to reduce the incidence of neonatal seizures, but there has been no beneficial effect in decreasing cerebral palsy or neonatal mortality. Internally monitoring involves a thin wire and electrode placed through the cervix and attached to the baby's scalp. < 32 weeks EGA: peak 10 bpm above baseline, duration 10 seconds but < 2 minutes from onset of the acceleration to return to baseline. The NICHD has stated that it is no longer useful to distinguish between short-term and long-term variability and has categorized variability into the following classifications, depending on the amplitude of the FHR tracing: absent (Online Figure C), minimal (Online Figure D), moderate (Online Figure E), and marked (Online Figure F).11, Sleep cycles of 20 to 40 minutes or longer may cause a normal decrease in FHR variability, as can certain medications, including analgesics, anesthetics, barbiturates, and magnesium sulfate.15 Loss of variability, accompanied by late or variable decelerations, increases the possibility of fetal acidosis if uncorrected.15, Sinusoidal pattern is a smooth, undulating sine wave pattern defined by an amplitude of 10 bpm with three to five cycles per minute, lasting at least 20 minutes.11 This uncommon pattern is associated with severe fetal anemia and hydrops, and it usually requires rapid intervention in these settings.15 Similar appearing benign tracings occasionally occur because of fetal thumb sucking or maternal narcotic administration, and generally these will persist for less than 10 minutes.15. Category II tracings may represent an appreciable fraction of those encountered in clinical care. 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. While caring for a gestational diabetic patient, you encounter a conflict with the attending physician because he refuses to order blood sugars on the patient. determination of *fetal blood pH or lactate: scalp blood sample* A more recent article on intrapartum fetal monitoring is available. Have you tested your EFM skills lately? It is important to recognize that FHR tracing patterns provide information only on the current acidbase status of the fetus. Data from: Macones GA, Hankins GD, Spong CY, et al. This depends on the source and duration of your increased heart rate. CVS: 8-12 weeks, checks genetic/biochemical abnormalities, and short waiting time. According to AWHONN, the normal baseline Fetal Heart Rate (FHR) is A. 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. Visually apparent, abrupt (onset to peak < 30 seconds) increase in FHR from baseline. Ayres-de-Campos D, Spong C, Chandraharan E. FIGO consensus guidelines on intrapartum fetal monitoring: Cardiotocography. Questions and Answers 1. The average rate ranges from 110 to 160 beats per minute (bpm), with a variation of 5 to 25 bpm. Here's what University of Michigan Medical Students said about the SecondLookTM concept: "The Second Look (files) have been a godsend. The fetal heart rate tracing shows ALL of the following: Baseline FHR 110-160 BPM, moderate FHR variability, accelerations may be present or absent, no late or variable decelerations, may have early decelerations. The baby may need to grow for another week or two before you and your healthcare provider can hear it. 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. (They start and reach maximum value in less than 30 seconds.) Consider need for expedited delivery (operative vaginal delivery or cesarean delivery). Incorrect. 1. Tracings meeting these criteria are predictive of normal fetal acid-base balance at the time of observation. Decrease in FHR from the baseline that is 15 bpm or more, lasting 2 minutes or more but less than 10 minutes in duration. 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. If any problems arise, reviews are done more frequently. What kind of variability and deceleration are seen in this strip?What interventions would you take after evaluating this strip?
