Post Dates Pregnancy Flashcards
(13 cards)
What is post term pregnancy
any pregnancy that has extended to or beyond 42 weeks of gestation(294 days after LMNP,28 day cycle),or estimated day of delivery(EDD)+ 14 DAYS
What causes postdates pregnancy?
- Miscalculation
- Irregular ovulation
- Anencephaly
How do you calculate gestation age in order to diagnose postdates pregnancy?
- Quickening
- Uterine size
- Ultrasound scan examination
- Amniocentesis
What would be the findings on ultrasound in postdate pregnancy?
a) Macrosomia
b) Oligohydramnios
c) Grade 2 and 3 placenta
Give 5 fetal complications of postdates pregnancy.
- foetal macrosomia
- Foetal Asphyxia
- dysmaturity syndrome
- higher rate of meconium aspiration
- higher rate of neonatal encephalopathy
- increased risk of placental insufficiency
- early neonatal death
Give 5 maternal complications of postdates pregnancy.
- increased risk of severe perineal injury.
- labour dystocia
- increased risk of endometritis
- chorioamnionitis
- caesarean delivery
- postpartum haemorrhage
What is included in fetal monitoring in the management of postdates pregnancy?
Non-stress test
Contraction stress test
Cardiotocography (CTG)
Biophysical profile
Define a non-stress test.
A nonstress test is a common prenatal test used to check on a baby’s health. During a nonstress test, the baby’s heart rate is monitored to see how it responds to the baby’s movements. The term “nonstress” refers to the fact that nothing is done to place stress on the baby during the test.
What is a Contraction test?
This test looks at how the baby’s heart rate reacts when the uterus contracts. During a contraction stress test, if adequate uterine activity doesn’t occur on its own the patient will be given intravenous oxytocin or be asked to rub their nipples to induce uterine activity.
What is Cardiotocography (CTG)?
measures the baby’s heart rate. At the same time it also monitors the contractions in the womb (uterus). CTG is used both before birth (antenatally) and during labour, to monitor the baby for any signs of distress. By looking at various different aspects of the baby’s heart rate, doctors and midwives can see how the baby is coping
What is a biophysical profile?
A biophysical profile combines a nonstress test with a foetal ultrasound that evaluates the baby’s breathing, body movements, muscle tone and amniotic fluid level.
Define induction of labour.
Induction of labour is the stimulation of contraction before the spontaneous onset of labour, with or without ruptured membranes.
Which drugs can e used to induce labor?
Oxytocin and prostaglandins like misoprostol and dinoprostone
