Intrapartum Fetal Monitoring - Article

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. Intraobserver variability may play a major role in its interpretation. To provide a systematic approach to interpreting the electronic fetal monitor tracing, the National Institute of Child Health and Human Development convened a workshop in 2008 to revise the accepted definitions for electronic fetal monitor tracing. The key elements include assessment of baseline heart rate, presence or absence of variability, and interpretation of periodic changes. The workshop introduced a new classification scheme for decision making with regard to tracings. This system can be used in conjunction with the Advanced Life Support in Obstetrics course mnemonic, DR C BRAVADO, to assist in the systematic interpretation of fetal monitoring. 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).


Interpretation of the Electronic Fetal Heart Rate During Labor - Article

ABSTRACT: Electronic fetal heart rate monitoring is commonly used to assess fetal well-being during labor. Although detection of fetal compromise is one benefit of fetal monitoring, there are also risks, including false-positive tests that may result in unnecessary surgical intervention. Since variable and inconsistent interpretation of fetal heart rate tracings may affect management, a systematic approach to interpreting the patterns is important. The fetal heart rate undergoes constant and minute adjustments in response to the fetal environment and stimuli. Fetal heart rate patterns are classified as reassuring, nonreassuring or ominous. Nonreassuring patterns such as fetal tachycardia, bradycardia and late decelerations with good short-term variability require intervention to rule out fetal acidosis. Ominous patterns require emergency intrauterine fetal resuscitation and immediate delivery. Differentiating between a reassuring and nonreassuring fetal heart rate pattern is the essence of accurate interpretation, which is essential to guide appropriate triage decisions.
