Obs - morbidity & mortality Flashcards
define stillbirth
Stillbirth occurs when a fetus is delivered after 24
completed weeks’ gestation showing no signs of life.
define neonatal death
Neonatal death is defined as death occurring within
28 days of delivery.
define early neonatal death
Early neonatal death occurs within 7 days of delivery.
define perinatal mortality rate
is the sum of stillbirths
and early neonatal deaths per 1000 total births.
what are the principal causes of perinatal mortality?
Unexplained antepartum stillbirth - perhaps aortocaval compression due to sleeping position of mother
Intrauterine growth restriction (IUGR) and placental
failure
Preterm delivery - MOST COMMON cause
Congenital anomalies
Intrapartum hypoxia
Antepartum haemorrhage
others:
infection, pre-eclampsiia (contributes to some of above)
define miscarriage
Miscarriage occurs when a fetus is born with no signs
of life before 24 weeks’ gestation
define maternal mortality
A maternal death is the death of a woman during pregnancy,
or within 42 days of its cessation, from any cause
related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes.
define late maternal death
A late maternal death is when a woman dies from pregnancy related
causes but more than 42 days-6weeks - 6months
after cessation of the pregnancy.
List the causes of maternal mortality ?
Direct: Thromboembolism - Most common Hypertensive disorders Ectopic pregnancy - rupture n bleed Haemorrhage Anaesthesia - eg epidural haematoma Acute fatty liver Sepsis - Group A strep
Indirect: Cardiac disease Neurological disease - eg epilepsy Respiratory - flu, asthma Psychiatric disease and suicide Others: domestic violence, drug/alcohol
What are the causes of maternal collapse?
Reversible causes ; The 4 H’s and 4T’s: o Hypoxia o Hyper/Hypokalaemia o Hypo/Hyperthermia o Hydrogen ions (acidosis) o Hypoglycaemia o Tension pneumothorax o Tamponade o Toxins o Trauma
Haemorrhage :
Placental abruption/praevia
Eclampsia - intracranial bleed
Drugs - local anaesthetic or illicit drugs
Cardiac - arrhythmias, MI
Infectious - Sepsis
How do you manage maternal collapse?
Responsive:
Call for senior help
Left lateral position, basic obs, fetal ctg
Unresponsive:
ABCDE
Oxygen, CPR (no pulse), get crash cart, call for senior help
No response -> perimortem csection
Responds -> post cardiac arrest treatment; oxygen, ecg, treat reversible causes eg hypothermia
