patterns of Category II tracings increase the difficulty of interpretation of FHR tracings (2). Chiossi et al reported that interpretation of FHR nonreassuring patterns are fraught with both uncertainty and fear of missing a decompensating pregnancy (4). The quality of the FHR tracing and scaling used on the monitor also affect interpretation (8).Category II FHR tracings 1, 2 are commonly encountered during labor. 3 Problems with interpretation of the category II FHR tracing, in part, stem from the diversity of FHR patterns that are included in this group. Additionally, the association between category II FHR tracings and fetal status and neonatal outcomes is poorly defined. category 2 tracing
ThreeTiered Fetal Heart Rate Interpretation System Category I Category I FHR tracings include all of the following: Baseline rate: beats per minute Category II Category II FHR tracings includes all FHR tracings not categorized as Category I or Category III. Category II tracings may represent an appreciable fraction of those
Algorithm for Management of Category 2 EFM (not meant for use with Category 1 or 3 tracings) Based on: Clark. Category II FHRT. Am J Obstet Gynecol 2013. Observe. Moderate Variability OR. Accelerations Significant decelerations with 50 of contractions for 1 hour not resolved with conservative At some point during labor, category I patterns were observed in over 99 percent of tracings, category II patterns were observed in 84 percent of tracings, and category III patterns were observed in 0. 1 percent of tracings.category 2 tracing There are 3 categories of fetal heart rate tracing: Category 1, 2, and 3 Definition of Category 1: Baseline rate of beatsmin moderate variability no late or variable decelerations early decelerations being present or absent accelerations being present or absent. Category 1 tracings are reassuring.
A common rationalization is that a CatII tracing is caused by a fetal sleep cycle, and that (againits hoped) the tracing will improve once the fetus awakens. There is an alternative to such hopeful watching and waiting: you cando something to improve the fetal status so that the FHR tracing converts to Category I. category 2 tracing 2 Why do we care about managing category lltracings? Category lltracings are a source of discomfort about management among care providers and nursing staff. In a study by Cahill including over 500 patients, the last 30 minutes of FHR tracings: 2. 3 were Category l 97. 6 were Category ll. 09 were Category lll We present an algorithm for the management of category II FHR patterns that reflects a synthesis of available evidence and current scientific thought. Use of this algorithm represents one way for the clinician to comply with the standard of care, and may enhance our overall ability to define the benefits of intrapartum FHR monitoring. Category I: Normal. The fetal heart rate tracing shows ALL of the following: Baseline FHR BPM, moderate FHR variability, accelerations may be present or absent, no late or variable decelerations, may have early decelerations. Strongly predictive of normal acidbase status at Free Category II Management Online App. The Category II Management App, a free webbased app offered exclusively by PeriGen, is based on published research and designed for US usage to help support the management of patients with FHR tracings in category II (present in over 80 of labors). . Only 48 clicks get you the suggested outcome and the app takes seconds to use.
