Relevant ACOG Resources. Fetal hypoxemia results in biphasic changes in the ST segment of the fetal electrocardiography (FECG) waveform and an increase in the T:QRS ratio.15 The ST-segment automated analysis (STAN) software from Noventa Medical can record the frequency of ST events and, combined with changes in continuous EFM, can be used to determine if intervention during the labor process is indicated.15 Several studies have evaluated FECG analysis, documenting its effectiveness at reducing operative vaginal deliveries, fetal scalp sampling, neonatal encephalopathy, and fetal acidosis (pH < 7.05).2528 One drawback to this technology is that it requires rupture of the membranes and internal fetal scalp monitoring. 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. If the baby is experiencing fetal bradycardia, that means it isn't getting . Whenever possible, they will implement measures to prevent an unfavorable outcome. 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.

Calculated as amplitude of peak-to-trough in bpm. These segments help establish an estimated baseline (for a duration of 10 minutes) which is expressed in beats per minute. Maxwell Spadafore is a fourth-year medical student at the University of Michigan Medical School. Weve also included information on the #OBGYNInternChallenge via @Creogsovercoffee. Moderate.
SecondLook - Fetal Heart Rate Tracing - University of Michigan This mobile app covers the following topics However, the strength of contractions cannot always be accurately assessed from an external transducer and should be determined with an IUPC, if necessary. Strongly predictive of normal acid-base status at the time of observation. When you've finished these first five, here are five more. This website provides entertainment value only, not medical advice or nursing protocols. 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. Am J Obstet Gynecol 1981; 140:435.
