B. Preterm is defined as babies born alive before 37 weeks of pregnancy are completed. As the maturity of the central nervous system occurs with advancing gestational age, this cycling of the fetal heart rate is established. Decreased blood perfusion from the fetus to the placenta these decelerations have a lower depth and duration, but can be seen frequently on intrapartum CTG tracings [4]. A. C. Umbilical cord entanglement A. Metabolic; lengthy C. Timing in relation to contractions, The underlying cause of early decelerations is decreased Overall clinical picture, including possibility of chorioamnionitis, should be considered, whilst managing these fetuses in labour. C. Metabolic alkalosis, _______ _______ occurs when the HCO3 concentration is lower than normal. Find the stress in the rod when the temperature rises to 40.0C40.0^{\circ} \mathrm{C}40.0C. Decreased FHR variability B. Biophysical profile (BPP) score A. Fetal bradycardia Patients 68 (41 males) small for gestational age (SGA) (birth weight <10th percentile) and 136 (82 males) appropriate for . Tachycardia leads to decreased time period between cardiac cycles, with a subsequent decrease in parasympathetic involvement and therefore baseline fluctuations. The aim of intrapartum continuous electronic fetal monitoring using a cardiotocograph (CTG) is to identify a fetus exposed to intrapartum hypoxic insults so that timely and appropriate action could be instituted to improve perinatal outcome. 15-30 sec A. Premature Baby Nursing Diagnosis and Nursing Care Plan Premature atrial contraction (PAC) Categorizing individual features of CTG according to NICE guidelines. Acceleration There are sub-categories of preterm birth, based on gestational age: moderate to late preterm (32 to 37 weeks). The relevance of thes B. Metabolic; short 2016 Mar 1;594(5):1247-64. doi: 10.1113/JP271091. Insufficient arterial blood flow causes decreased nutrition and oxygenation at the cellular level. The use of CTG monitoring in this group is contentious and each case should be considered individually with a plan of care agreed following discussion between the patient, obstetrician, and neonatologists. ACOG, Intrapartum fetal heart rate monitoring: nomenclature, interpretation, and general management principles, ACOG Practice Bulletin, vol. What characterizes a preterm fetal response to interruptions in oxygenation Any condition that predisposes decreased uteroplacental blood flow can cause late decelerations. B. B. Both components are then traced simultaneously on a paper strip. absent - amplitude range is undetectable. NCC EFM practice Flashcards | Quizlet C. Marked variability, Common problems seen during monitoring of postterm fetuses include all of the following except An increase in gestational age The present study provides evidence that prolonged fetal inflammation during pregnancy induces neurovascular abnormalities in the cerebral cortex and white matter of preterm fetal sheep. Several characteristics of FHR patterns are dependant on gestational age as they reflect the development and maturity of cardiac centres in the central nervous system as well as the cardiovascular system and, hence, differ greatly between a preterm and a term fetus.
