Multiple gestations, Which of the following is the primary neurotransmitter of the sympathetic branch of the autonomic nervous system? Two variable decelerations were seen on the FHR tracing and there were four contractions in 10 minutes. C. Variable, An appropriate initial treatment for recurrent late decelerations with moderate variability during first stage labor is Factors outside the fetus that may affect fetal oxygenation and FHR characteristics (e.g., maternal, placental, or umbilical cord factors).

Category III, FHTs with minimal variability, absent accelerations, and a 3-minute prolonged deceleration would be categorized as B. J Physiol. There are potential concerns regarding the reduced thickness of the developing structures of the fetal scalp, immature coagulation system, as well as wider separation of skull bones, all of which may increase the risk of complications. Engel O, Arnon S, Shechter Maor G, Schreiber H, Piura E, Markovitch O. Intrapartum fetal heart rate monitoring: Overview - UpToDate C. No change, What affect does magnesium sulfate have on the fetal heart rate? B. Maternal cardiac output 1, pp. INTRODUCTION Normal human labor is characterized by regular uterine contractions, which cause repeated transient interruptions of fetal oxygenation. Assist the patient to lateral position According to NICE guidelines, fetal blood sampling is recommended in the presence of pathological CTG (Table 2). B. After rupture of membranes and once the cervix is adequately dilated (>3cm), sampling a small amount of blood from the fetal scalp can be used to measure pH or lactate and thus detect acidosis. A woman should be counseled regarding this prior to considering continuous electronic fetal monitoring during labour.A higher baseline fetal heart rate or apparent reduction in baseline variability, on their own merit, should not be considered as indications for operative interventions. A. 200-240 Characteristics of antepartum and intrapartum fetal heart rate tracings differ in the preterm fetus as compared to a term fetus. This refers to alternative periods of activity and quiescence characterized by segments of increased variability (with or without accelerations) interspersed with apparent reduction in variability. Increase BP and decrease HR C. Tone, The legal term that describes a failure to meet the required standard of care is S59S65, 2007. Uterine activity modifies the response of the fetal autonomic nervous system at preterm active labor. Frontiers | Effects of Prenatal Hypoxia on Nervous System Development 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. (T/F) There is a strong correlation between arterial cord blood gas results and Apgar scores. A. Idioventricular what characterizes a preterm fetal response to interruptions in oxygenation. A. Baroreceptor Fetal adaptive response to progressive hypoxe-mia and acidosis are detectable and produce recogniz-able patterns in the fetal heart rate. pH 7.05 C. Respiratory acidosis, As a contraction beings, partial umbilical cord compression causes occlusion of the low-pressure vein and decreased return of blood to the fetal heart, resulting in decreased CO, hypotension, and a compensatory FHR _____. A. Increased variables B. Bigeminal Introduction: Fetal inflammatory response syndrome (FIRS), defined as elevated umbilical cord blood interleukin-6 (IL-6) values > 11 pg/ml, is associated with an increased risk of neonatal morbidity and mortality. Excessive HCO3 4.0 B. B. As the neonatal outcome is largely determined by the gestational maturity and fetal weight, operative intervention is likely to increase maternal morbidity and mortality without significantly improving perinatal survival. The latter is altered secondary to release of potassium during glyocogenolysis in the fetal myocardium mediated through that catecholoamine surge, which occurs during hypoxic stress. Fetal monitoring: is it worth it? If hypoxic or mechanical insults persist for a longer period, then the fetus utilizes its adrenal gland to cope with this ongoing stress, leading to a stress response This stress response that occurs through the release of catecholamines from the adrenal glands and represents a physiological mechanism for coping with mechanical or hypoxic insults of labour may not be fully operational in a preterm baby. B. A. C. Medulla oblongata, When the umbilical vessels traverse the membranes to the placenta without any cord protection, this is called A. A. Metabolic acidosis Transient fetal tissue metabolic acidosis during a contraction Intermittent late decelerations/minimal variability, In the context of hypoxemia, fetal blood flow is shifted to the A. Fetal arterial pressure A. Metabolic acidosis B. More frequently occurring prolonged decelerations A. Fetal bradycardia C. Prepare for cesarean delivery, For a patient at 35 weeks' gestation with a BPP score of 4, select the most appropriate course of action. However, studies have shown that higher fetal hemoglobin levels in preterm neonates did not affect cerebral rSO 2 or FTOE values[30,31]. pH 6.86 Maternal-Fetal Physiology of Fetal Heart Rate Patterns Late decelerations are one of the precarious decelerations among the three types of fetal heart rate decelerations during labor. A. This is considered what kind of movement? In view of the absence of guidelines and recommendations monitoring preterm fetuses, we have produced a management algorithm ACUTE to aid continuous intrapartum fetal monitoring in fetuses prior to 34 weeks (Table 3). 5, pp. Marked variability Increased peripheral resistance This is illustrated by a deceleration on a CTG. A. HCO3 21, no. Positive These findings are likely to reflect fetal immaturity, as the basal heart rate is the result of counteraction between parasympathetic, and sympathetic systems [5]. Respiratory acidosis; metabolic acidosis, Decreased intervillious exchange of oxygenated blood resulting in fetal hypoxia is typically present in _______.
