C. 30 min, Which of the following tachyarrhythmias can result in fetal hydrops? In cases of pre-term prelabour rupture of membranes, maternal infection and the risk of chorioamnionitis should not be overlooked. It is not recommended in fetuses with bleeding disorders and is contraindicated in pregnancies complicated with HIV, Hepatitis B or C as it may increase vertical transmission. 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. 34, no. It should be remembered that the physiological reserves to combat hypoxia are not as robust as a term fetus, especially, if the onset of preterm labour is secondary to an infective process.

Persistent tachycardia is likely to arise secondary to iatrogenic causes such as administration of tocolytics (terbutaline) [9]. 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.

Based on current scientific evidence, a CTG is not recommended in the UK as a method of routine fetal assessment of the preterm fetus (<37 weeks gestation) and currently no clinical practice guidelines on intrapartum monitoring of the preterm fetus exist in the UK The International Federation of Gynaecologists and Obstetricians (FIGO) guidelines for interpretation of intrapartum cardiotocogram distinguish 2 levels of abnormalities, suspicious and pathological, however, the gestation to which such criteria can be applied has not been specified. Decreased FHR late decelerations B. Bigeminal B. Tachycardia leads to decreased time period between cardiac cycles, with a subsequent decrease in parasympathetic involvement and therefore baseline fluctuations.

One of the important characteristics of fetal development is that, with the decrease in oxygen supply, the blood flow of other organs is rapidly redistributed to the brain and heart, increasing by 90 and 240%, respectively, a response that is similar in both preterm and near-term fetuses (Richardson et al., 1996). D. Ephedrine administration, When an IUPC has been placed, Montevideo units must be ___ or greater for adequate cervical change to occur. C. Category III, Maternal oxygen administration is appropriate in the context of Several theories have been proposed as a potential explanation for this fetal heart rate pattern, notably decreased amount of amniotic fluid, reduced the Wharton jelly component in the cord of the preterm fetus and lack of development of the fetal myocardium and, therefore, the resultant reduced force of contraction. B. B. 3, p. 606, 2006. Etiology of a baseline FHR of 165bpm occurring for the last hour can be: The most prevalent risk factor associated with fetal death before the onset of labor is: In the presence of other reassuring features of the CTG (as outlined above), these decelerations should not be considered as indicative of hypoxia, and interventions should be avoided based on this parameter alone. A.
