Amniotic Fluid Embolism Flashcards
What are the risk factors for an amniotic fluid embolism
- Multiple pregnancy
- Increasing maternal age
- Induction of labour
- Uterine rupture
- Placenta praevia
- Placental abruption
- Cervical laceration
- Eclampsia
- Polyhydramnios
- Caesarean or instrumental delivery
What are the clinical features of an amniotic fluid embolism
Sudden onset:
- Hypoxia/respiratory arrest
- Hypotension
- Fetal distress
- Seizures
- Shock
- Confusion
- Cardiac arrest
- DIC
How should an amniotic fluid embolism be investigated?
Bloods = FBC, U+Es, Ca, Mg, clotting, ABG
ECG = ischemic changes
CXR = pulmonary oedema
Pulmonary artery wedge pressure
How should a amniotic fluid embolism be managed
A-E
Oxygen
Fluids
DIC - involve haematologist
Fetal monitoring
Perimortem section - indicted to facilitate CPR
How is an amniotic fluid embolism diagnosed?
Definitive diagnosis of amniotic fluid embolism is only definitively confirmed on post mortem and demonstrates fetal squamous cells along with debris in the pulmonary vasculature
