Dr. Hammoud has dedicated her career to medical student education and serves in many educational leadership roles locally and nationally. What kind of decelerations and variability does this strip show? Avoid fetal "keepsake" images, heartbeat monitors. 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. Currently she serves as President of the Association of Professors of Gynecology and Obstetrics (APGO). The definition of a significant deceleration was [10]: Test your EFM skills using NCC's FREE tracing game! Yes.

What does it mean to have a "reactive strip"? Continuous EFM reduced neonatal seizures (NNT = 661), but not the occurrence of cerebral palsy. Corticosteroid administration may cause an increase in FHR accelerations. Marked. 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.

This may cause unnecessary worry for parents. What is the baseline of the FHT? You have to lie down or sit in a reclined position for the test, which lasts about 20 minutes. Variability describes fluctuations in the baseline FHR, whether in terms of frequency, amplitude, or magnitude. 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.

The onset, nadir, and recovery of the deceleration usually coincide with the beginning, peak, and ending of the contraction, respectively.11 Early decelerations are nearly always benign and probably indicate head compression, which is a normal part of labor.15, Variable decelerations (Online Figure I), as the name implies, vary in terms of shape, depth, and timing in relationship to uterine contractions, but they are visually apparent, abrupt decreases in FHR.11 The decrease in FHR is at least 15 bpm and has a duration of at least 15 seconds to less than two minutes.11 Characteristics of variable decelerations include rapid descent and recovery, good baseline variability, and accelerations at the onset and at the end of the contraction (i.e., shoulders).11 When they are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions.11 Overall, variable decelerations are usually benign, and their physiologic basis is usually related to cord compression, with subsequent changes in peripheral vascular resistance or oxygenation.15 They occur especially in the second stage of labor, when cord compression is most common.15 Atypical variable decelerations may indicate fetal hypoxemia, with characteristic features that include late onset (in relation to contractions), loss of shoulders, and slow recovery.15. doi:10.1136/hrt.2005.069369.
