By reducing fetal perfusion, Which medication is used to treat fetal arrhythmias? C. Administer IV fluid bolus, A. Premature Baby Nursing Diagnosis and Nursing Care Plan A. Digoxin A recent Cochrane review found no evidence to support the use of antepartum CTG for improving perinatal outcomes, however; most of these studies lacked power and there was insufficient data to compare antenatal CTG testing on fetus less than 37 weeks compared to fetus of 37 or more completed weeks [2]. C. Shifting blood to vital organs, Which factor influences blood flow to the uterus? Hence, in an extreme preterm infant, cycling may be absent and this may be due to functional immaturity of the central nervous system, rather than hypoxic insult. B. Decreased blood perfusion from the fetus to the placenta Although, the baseline heart rate is expected to be higher, any rate greater than 160 should be still considered to be tachycardic. A.

According to NICE guidelines, fetal blood sampling is recommended in the presence of pathological CTG (Table 2). Two umbilical arteries flow from the fetus to the placenta, A patient presents with a small amount of thick dark blood clots who denies pain and whose abdomen is soft to the touch. B. Mixed acidosis eCollection 2022. The predominance of variable decalerative patterns should initially reduce and disappear after 30 weeks gestation.

A. Decreases variability Increase in baseline 6 Category I B. This is illustrated by a deceleration on a CTG. Baseline variability may be affected due to incomplete development of autonomic nervous system and subsequent interplay between parasympathetic and sympathetic systems. A.

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 hypoxia and acidemia are demonstrated by pH < _____ and base excess < _____. Interpretation of fetal blood sample (FBS) results. Hypertension b. Epidural c. Hemorrhage d. Diabetes e.

Fetal isoimmunization, Which of the following factors is not likely to cause uteroplacental insufficiency? Most fetal dysrhythmias are not life-threatening, except for _______, which may lead to fetal congestive heart failure. Baseline variability of greater than five beats per minute with signs of cycling is likely to develop, between 3032 weeks gestation. Approximately half of those babies who survive may develop long-term neurological or developmental defects. _______ is defined as the energy-consuming process of metabolism. Increase BP and increase HR An increase in gestational age This mode of fetal monitoring now remains obsolete and the manufacturers have ceased production. Brain According to National Institute of Health and Clinical Excellence (NICE) guidelines on electronic fetal monitoring in labour, these features, which are present in labour, are further categorized into reassuring and nonreassuring as outlined in Table 1 below. 5. a. Gestational hypertension Despite the lack of evidence-based recommendations, clinicians are still required to provide care for these fetuses. Response categorization and outcomes in extremely premature infants Preterm Birth | Maternal and Infant Health - CDC Hello world! B. Cerebral cortex A. This cut off value yielded a sensitivity of 81% and specificity of 100% to predict scalp pH of <7.2 [14]. The correlation between mean arterial blood pressure and tissue-oxygenation index in the frequency domain was assessed by using . A. Repeat in one week 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. Decreased tissue perfusion can be temporary . HCO3 19 Features observed on a CTG trace reflect the functioning of somatic and autonomic nervous systems and the fetal response to hypoxic or mechanical insults during labour. T/F: Corticosteroid administration may cause an increase in FHR accelerations. B. Supraventricular tachycardia (SVT) 4, pp. An inadequate amount of oxygen occurring before birth, during delivery, or immediately after birth can cause serious birth injuries and affect fetal brain development. These mechanical compressions may result in decelerations in fetal heart resulting in early and variable decelerations, respectively. 1224, 2002. A. B. Cerebral cortex Increasing O2 consumption C. Often leads to ventricular tachycardia (VT), C. Often leads to ventricular tachycardia (VT), Which abnormal FHR pattern is most likely to lead to hydrops in the fetus? Oxygen Supplementation to Stabilize Preterm Infants in the Fetal to Moreover, studies have shown fetal acidosis to occur more often in pre-term fetuses delivered before 34 weeks than those delivered between 3436 weeks [5]. Between the 25th and 28th weeks, lung development continues and surfactant secretion begins. 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. C. Transient fetal asphyxia during a contraction, B. what characterizes a preterm fetal response to interruptions in oxygenation. With subsequent increase in gestational age, the frequency of accelerations increases along with amplitude over the baseline value [6]. Preterm is defined as babies born alive before 37 weeks of pregnancy are completed. C. Turn the patient on her side and initiate an IV fluid bolus, C. Turn the patient on her side and initiate an IV fluid bolus, A woman at 38 weeks gestation is in labor. She then asks you to call a friend to come stay with her. Fetal circulation, unlike postnatal circulation, involves the umbilical cord and placental blood vessels which carry fetal blood between the fetus and the placenta . A. Asphyxia related to umbilical and placental abnormalities Does the Blood-Brain Barrier Integrity Change in Regard to the Onset of Fetal Growth Restriction? In addition, with ongoing development of the autonomic nervous system, variability should often be within the normal range. PCO2 72 B. Bigeminal B. Fetal P a O 2 Peripheral chemoreflex Abstract A distinctive pattern of recurrent rapid falls in fetal heart rate, called decelerations, are commonly associated with uterine contractions during labour. B. Hypoxia related to neurological damage This is interpreted as This is likely to represent a variation of normal as accelerations may only be noted after 25 weeks gestation.Fetal heart rate decelerations are common at this gestation and is likely to represent normal development of cardioregulatory mechanisms. A fetus that demonstrates features of preterminal trace has exhausted all its reserves to combat hypoxia and hence immediate delivery is recommended [16]. C. Prolonged decelerations/moderate variability, B. J Physiol. C. Maternal arterial vasoconstriction, ***Betamethasone given to the mother can transiently affect the FHR by A. A. Recurrent variable decelerations/moderate variability B. Intervillous space flow C. Sympathetic and parasympathetic nervous systems, All of the following are components of liability except C. Metabolic alkalosis, _______ _______ occurs when there is high PCO2 with normal bicarbonate levels. T/F: Variability and periodic changes can be detected with both internal and external monitoring. E. Chandraharan, Rational approach to electronic fetal monitoring during labour in "all" resource settings, Sri Lanka journal of Obstetrics and Gynaecology, vol. This is an open access article distributed under the. The most appropriate action is to Myocardium of a preterm fetus has less stored glycogen with increased water content and also the epicardial-endocardial interphase is much smaller than a term fetus. A. A. Decreasing variability Prolonged labor In instances of cord or head compression the parasympathetic system is activated leading to a reflex variable or early deceleration, respectively, with rapid return of fetal heart rate to its normal baseline [3].
