Pathologies of Pregnancy Flashcards
problem with warfarin in pregnancy
it’s teratogenic (harms baby in 1st trimester)
low BP and high heart rate is what
schock
what features of an ectopic pregnancy predisposes it to haemorrhage
lack of decidual layer and a small tube
what cells in the decidual layer are procoagulant
stromal cells
what is a chorionic villi
projection of developing placenta into the mother’s blood supply. Tends to be covered in trophoblasts
what condition sees an excess of chorionic villi on microscopy
molar pregnancy
what scan shows nuchal thickening and what does it indicate
ultrasound - down’s syndrome
what chromosome abnormality is down’s
trisomy 21 (a 3rd 21 chromosome)
what follow up test can be done to confirm diagnosis of down’s
amniocentesis
what is duodenal atresia
a loss or closure of part of the duodenum
what is IUD in obstetrics
intrauterine death
why do babies get so big when mum has diabetes
glucose crosses placenta and into baby. Baby’s insulin goes up to deal with all the glucose but can’t bring it back down because more keeps coming from mum. Baby grows lots and lots
risks of a diabetic mother on baby
big baby, still birth, malformations, neonatal hypoglycaemia
why do diabetic mum babies die intrauterine
sudden metabolic and hypoxic problems brought on by the glucose
why do neutrophils have segmented nuclei
allows them to squeeze between other cells and travel to site of injury
how might infection reach the amniotic sac
ascending through vagina from perineum or anus
what cell is abnormally present in the placenta, cord or membrane in acute inflammation
neutrophils
name for infection of placental membranes
chorioamnionitis
if baby survives chorioamnionitis how will it progress postnataly
ill in first days of life and cerebral palsy late in life
describe the damage of chorioamnionitis on the baby’s brain
neutrophils –> cytokine storm –> activate brain cells –> +normal hypoxia of labour = damage
do opiates cross the placenta
yes - because they are very small molecules
examples of opiates
heroin, methadone, morphine
result of an overtwisted cord
intrauteirne death
what score is used to assess a newborn baby
APGAR (appearance, pulse, grimace, activity, respiration)
