FIGO consensus guidelines on intrapartum fetal monitoring: Cardiotocography. 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).

Once I complete the Second Look, I know I'm ready to quiz. Tracings of the normal fetal heart rate are between 120 and 160. can you recognize these strip elements? Nadir of the deceleration = peak of the contraction. 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. This measurement helps healthcare providers determine the well-being of the fetus during prenatal visits or labor. -pressure on fetal head Differentiate maternal pulse from fetal pulse, 4. *fetal stimulation: digital scalp stim, vibroacoustic stim* Ectopic Pregnancy Quiz Questions And Answers. 2016;123(6):870-870. doi:10.1111/1471-0528.13844. -acceleration in response means that acidosis is unlikely > 2 min., but < 10 min in ACOG recommends using a three-tiered system for the categorization of FHR patterns.

Needs immediate intervention; may be due to severe fetal anemia, abdominal trauma or serious fetal infection. A more recent article on intrapartum fetal monitoring is available. Compared with EFM alone, the addition of fetal electrocardiography analysis results in a reduction in operative vaginal deliveries (NNT = 50) and fetal scalp sampling (NNT = 33). You should first. Onset, depth, and duration commonly vary with successive uterine contractions. Late decelerations (Online Figure J) are visually apparent, usually symmetric, and have the characteristic feature of onset of the deceleration after the onset of the uterine contraction.11 The timing of the deceleration is delayed, with the nadir of the deceleration occurring after the peak of the contraction.11 The onset, nadir, and recovery of the deceleration usually occur after the beginning, peak, and ending of the contraction, respectively. Healthcare providers usually start listening for a babys heart rate at the 10- to 12-week prenatal visit using a Doppler machine.

Fetal bradycardia is a fetal heart rate of less than that 110 bpm, which is sustained for greater than or equal to 10 minutes. It is common to have a baseline heart rate of between 100-120 bpm in the following situations: Postdate gestation Occiput posterior or transverse presentations Severe prolonged bradycardia (less than 80 bpm for more than 3 minutes) indicates severe hypoxia.

Intrapartum fetal heart rate monitoring. -*associated w decreased or absent FHR variability*, 110-160 bpm These segments help establish an estimated baseline (for a duration of 10 minutes) which is expressed in beats per minute. Contractions cause an increase in uterine venous pressure and a decrease in uterine artery perfusion. The normal range for baseline FHR is defined by NICHD as 110 to 160 beats per minute (bpm; Online Figure A). A baseline of less than 110 bpm is defined as bradycardia.11 Mild bradycardia (100 to 110 bpm) is associated with post-term infants and occipitoposterior position.15 Rates of less than 100 bpm may be seen in fetuses with congenital heart disease or myocardial conduction defects.15 A baseline greater than 160 bpm is defined as tachycardia11 (Online Figure B).

Write a program that checks whether a sequence of HTML tags is properly nested. 1. 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.
