The perception that structured intermittent auscultation increases medicolegal risk, the lack of hospital staff trained in structured intermittent auscultation, and the economic benefit of continuous EFM from decreased use of nursing staff may promote the use of continuous EFM.8 Online Table A lists considerations in developing an institutional strategy for fetal surveillance. The main goal is to identify fetuses who are prone to injuries stemming from hypoxia (or a lack of oxygen for fetal tissues). Tapping "Update" will cause the slide decks to be updated. Detection is most accurate with a direct fetal scalp electrode, although newer external transducers have improved the ability to detect variability.

Variability describes fluctuations in the baseline FHR, whether in terms of frequency, amplitude, or magnitude. Scroll down for another when you're done. 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. You must know how to identify early decelerations, late decelerations, and variable decelerations.

Registered Nurse, Free Care Plans, Free NCLEX Review, Nurse Salary, and much more. The workshop introduced a new classification scheme for decision making with regard to tracings. Your doctor analyzes FHR by examining a fetal heart tracing according to baseline, variability, accelerations, and decelerations. Your obstetrician reviews the fetal heart tracing at regular time intervals. Fluctuations in the baseline FHR that are irregular in amplitude and frequency.

Check out a suggested systematic approach from the AAFP below! Continuous EFM may adversely affect the labor process and maternal satisfaction by decreasing maternal mobility, physical contact with her partner, and time with the labor nurse compared with structured intermittent auscultation.7 However, continuous EFM is used routinely in North American hospitals, despite a lack of evidence of benefit.

The second half of the 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.
