Flashcards in W11_06 Intrapartum care, abnormal labour, obstetrical emergencies Deck (39)
define labour in its two components
contractions and cervical change
what's an effaced cervix?
thinned out, ready for birth
what's a breech presentation?
baby is facing bottom down in the uterus;
complete breech is both legs and hips flexed
what's a Frank breech?
both hips flexed
what's the typical "lie" in intrapartum fetuses?
longitudinal, not transverse
what's the body part for reference in vertex presentations?
occiput (anterior, posterior)
what's the body part for reference in breech presentations?
what's the body part for reference in face presentations?
define "station" in ob/gyn
distance of the baby's head wrt the mother's ischial spine
what's the latent first stage?
what's the active first stage?
3-10cm dilation; dilation goes more quickly in multiparous women
define the time of second stage
time between full dilation (10cm) to complete birth;
typically within 2 hours
what are the 7 cardinal movements of labour?
internal rotation (occiput facing mom pubic symphysis)
extension then crowning
define the time of the third stage of labour
delivery of the fetus to the placenta;
within 30 mins
define the time of the fourth stage of labour
delivery of placenta to the stabilization of the patient's condition (6 hours)
what causes ferning of amniotic fluid?
what's the pH of amniotic fluid?
what does green amniotic fluid mean?
warning - fetus might be passing meconium. Check the fetal heart rate and see what's going on
changes in FHR may precede which type of injury?
what are the two types of fetal heart rate monitoring?
intermittent auscultation (e.g. with doppler);
continuous electronic fetal monitoring
what's the normal fetal heart rate?
what do we look for in electronic fetal monitoring?
uterine activity pattern;
variability and accelerations
what can cause variable deceleration?
what do late decelerations imply?
uteroplacental insufficiency and some degree of hypoxia
when do late decelerations occur wrt to contractions?
AFTER the contraction
when do early decelerations occur wrt to contractions?
during uterine contraction;
associated with head compression, benign
what to do when the OB tracing is abnormal?
reposition to left/right lateral;
improve hydration with IV fluid bolus;
perform vag exam to relieve pressure;
administer oxygen by face mask;
consider internal scalp electrode on baby;
consider fetal scalp sampling;
what does the fetal scalp sample look for?
note: there are non-pharmacologic obstetrical analgesias
