Q

what is placenta increta

A

severe complication where the placenta implants too deeply and its villi invade the muscular wall of the uterus (the myometrium), but don’t go all the way through it
usually no sx in pregnancy but can cause dangerous, life-threatening bleeding during childbirth and often requires a C-section, potentially followed by a hysterectomy
so only really realise it during childbirth
often suspected if pt has placental praevia or previous C section

Q

management of amniotic fluid embolism

A

ABCDE + call ITU reg

A –> maintain patency
B –> high flow O2 +/- intubation
C —> 2 large bore cannulae + fluid resus

drugs –> ionotropics eg dopamine/dopabutamine/noradrenaline
(to improve heart contractility)

if haven’t already, consider delivery +/- hysterectomy

453
what is placental abruption
placenta separates from the uterine wall during pregnancy resulting in maternal haemorrhage into intervening space
454
