delivery emergencies Flashcards
what is maternal collapse ?
acute event involving the cardiorespiratory system or nervous system resulting in reduced or absent conscious levels at any stage in pregnancy and up to 6 weeks after birth
what are the causes of maternal collapse ?
4 Hs hypoxia hypovolemia hypo/hyperkalemia and hyponatraemia hypothermia
4 Ts Thromboembolism Toxicity tension pneumothorax Tamponade Eclampsia and pre-eclampsia
what is the presentation of amniotic fluid embolus ?
( amniotic fluid enters the blood stream of the mother)
presents as collapse during labour or birth in the form of:
acute hypotension
respiratory distress
acute hypoxia
seizure and cardiac arrest may occur
if the mother survives long enough after a maternal collapse what is most likely to develop ?
coagulopathy
what is the best initial management of maternal collapse ?
ABCDE approach to the patient
relieve aortocaval compression by moving the uterus to the left in women above 20 weeks of gestation
what is aortocaval compression ?
when na pregnant uterus compresses on the abdominal aorta and the IVC
what is the management in the case of maternal collapse secondary to antepartum haemorrhage
the fetus and the placenta should be delivered to allow control of the haemorrhage
along with the administration of tranexamic acid
what is the management for amniotic fluid embolus ?
supportive rather than specific :
Oxygen + ventilate
Deliver the baby as soon as
possible
what is expected to happen after amniotic fluid embolism ?
vaginal bleeding due to coagulopathy/DIC
what is the antidote for magnesium sulphate toxicity ?
10% calcium gluconate
or
10% calcium chloride
if local anesthetic toxicity is suspected what is the best step inn management ?
stop injecting
lipid rescue should be used
what is cord prolapse ?
umbilical cord drops through the cervix and out into the vagina before the baby moves into the birth canal
what is cord presentation ?
the cord lies below the presenting part with an intact membrane
what is the preferred method of delivery in cases of cord prolapse ?
CS is usually indicated inn order to prevent hypoxic acidosis
when should cord prolapse be suspected ?
when there is an abnormal fetal heart rate pattern especially if these changes start soon after rupture of membranes
