Intrauterine Fetal Death Flashcards
Stillbirth
Child delivering after 24 weeks of pregnancy that doesn’t breathe or show any other signs of life
Types of IUD
1 - antepartum fetal death
2 - intrapartum fetal death
Causes of antepartum fetal death
Maternal(DM, HTN)
Fetal (fetal immune hemolytic disease and cord accidents)
Placental (twin twin transfusion, abruption, infarction, fetal to maternal haemorrhage)
Spalding sign
Overlapping of fetal skull bones on X-ray . Diagnostic of IUD
Robert sign
Gas shadow in fetal circulatory system on x ray. Diagnostic of IUD
Ultrasound signs of IUD
Absent fetal heart activity Collapsed skull Non filled aorta Retraction of brain tissue Poorly visualised mildline falx echo Empty fetal bladder
Management of IUD baby
Either induction of labour or conservative management
Pros for induction of labour after iud diagnosis
Coagulopathy starts within 48 hours of fetal demise
Post mortem is more effective on a fresh dead baby
Psychologically daunting to carry a dead fetus
Pros for conservative management after IUD
Spontaneous labour starts in a few weeks. Induction can lead to induction failure and c section. Coagulopathy evident only after 4 weeks
What is contraindicated for induction in IUD baby
ARM as it can lead to infection if there is intrauterine death
Conservative management in IUD
Coagulation profile is checked every week. If it develops then it has to be reversed before induction of labour. Low dose heparin is used. PTT kept at 2.5 times normal. When fibrinogen is above 200 mg/dl heparin is stopped and labour induced after 6 hours.
If patient of coagulopathy goes into spontaneous labour , fresh blood, FFP and cryoprecipitate is given. Heparin is contraindicated
Indications for c section in dead fetus (absolute)
1- placenta Previa of major degree 2 - severe CPD 3 - previous classical c section 4 - 2 or more previous c sections 5 - obstructed labour 6 - uterine rupture
Relative indications for c section of dead baby
1- previous 1 c section
2 - transverse lie or shoulder presentation
3 - fetal tumor or abdominal distension
Intrapartum death
Death of baby weighing 1.5 kg or more. After onset of labour. Within 28 days. Related to intrapartum events
Causes of intrapartum death
1- long trial of labour in already compromised baby
2- Missed CPD
3- missed malpresentation
4 - mishandling of breech
