Intrauterine fetal demise: Difference between revisions

Latest revision as of 02:19, 8 August 2020

Background

Definition

Death of fetus in the uterus antepartum after 20 weeks gestation
- Also called intrauterine fetal demise (IUFD)
Compared to stillbirth, where death is ante- or peripartum after 20 weeks gestation
- Fresh: delivered within 24h of fetal death
  - Zero degree: red skin suggests less than 8h dead
- Macerated: delivered after 24h of fetal death
  - First degree: peeling skin suggests more than 8h from death
  - Second degree: 2-7 days, effusion of skin
  - Third degree: >7 days, yellow liver
Spontaneous abortion if less than 20 weeks gestation

Etiology

Idiopathic, most commonly
Maternal
- Diabetes mellitus
- Antiphospholid antibody syndrome
- TORCH syndrome
- Preeclampsia
- Quite rinse rupture (??)
- Porphyria
Fetal
Placental
- Placental abruption
- Placental insufficiency

Risk factors

African-American
Maternal infertility
Maternal age >40 years
Male fetus
Multiple gestation
Multiparty

Clinical Manifestations

Decreased fetal movement
Absent fetal heart beat

Investigations

Ultrasound for diagnosis
- Spalding sign: overlapping fetal skull bones
- Robert sign: gas in the heart and vessels
Assess for DIC
- Platelets
- Fibrinogen
- INR/PTT
To investigate etiology
- CBC
- Blood glucose or HbA1c
- Lupus anticoagulant
- VDRL and TORCH screen
- Placental culture
Examine the fetus after delivery for signs of trisomies, hydrocephalus
- X-ray
- MRI
- Autopsy

Management

Diagnose with ultrasound
Assess risk of DIC
Deliver the fetus, preferably vaginally
- Induction (preferred)
  - First-line:
    - Misoprostol 25-50 mcg q4h
    - If no progress after 24h, consider Cesarean section
  - Second-line: oxytocin
- Expectant management
  - Expected to deliver in 1-2 weeks
  - Counsel the patient
  - Follow coagulation status to monitor for DIC
Evaluate the fetus after delivery
Counsel and reassure the parents
Prevent breast milk
- First-line: cabergoline once
- Last-line: bromocriptine
