Algorithm Steps
13 total
01Start 02Action Clinical Presentation
Key features of placental abruption
- Vaginal bleeding (may be absent in concealed)
- Abdominal pain (constant, unlike labor)
- Uterine tenderness and rigidity
- High-frequency contractions
- Fetal heart rate abnormalities
- Back pain if posterior placenta
03Action Initial Management
Stabilize mother and assess fetus
- 2 large-bore IVs (16-18G)
- Aggressive fluid resuscitation
- Type and crossmatch 4+ units
- Continuous fetal monitoring
- Foley catheter - monitor output
- Labs: CBC, coagulation panel, fibrinogen, type and screen
04Decision Assess Severity
Grade of abruption determines management
- MILD (Grade 1): <100mL blood loss, no distress
- MODERATE (Grade 2): 100-500mL, some distress, tender uterus
- SEVERE (Grade 3): >500mL, fetal death or DIC, shock
05Action Mild Abruption - Expectant Management
If preterm and stable, may observe
- Continuous monitoring initially
- Serial labs q4-6h
- Steroids if <34 weeks
- Bed rest and observation
- May consider discharge if completely stable
- Delivery if worsening or term
06Outcome Postpartum Management
High risk for PPH and complications
- High risk for uterine atony
- Aggressive uterotonic use
- Monitor for ongoing DIC
- Transfuse to correct anemia/coagulopathy
- Close monitoring in recovery/ICU
07Warning Moderate/Severe Abruption - Urgent Delivery
Delivery is definitive treatment
- Prepare for cesarean if fetal distress
- Vaginal delivery acceptable if stable and progressing
- Amniotomy may accelerate labor
- Continuous monitoring essential
- Blood products ready
08Decision DIC/Coagulopathy Present?
Check fibrinogen, PT/PTT, platelets
- Fibrinogen <200 mg/dL is concerning
- Fibrinogen <100 mg/dL = DIC
- Elevated PT/INR, PTT
- Thrombocytopenia
- Elevated D-dimer (less specific)
09Action DIC Management
Aggressive blood product replacement
- Massive transfusion protocol
- FFP to correct PT/INR
- Cryoprecipitate: 10 units (target fibrinogen >150)
- Platelets if <50,000
- 1:1:1 ratio if massive hemorrhage
- Delivery is essential to stop process
10Decision Route of Delivery
Based on fetal status and labor progress
11Action Emergency Cesarean
Indications for operative delivery
- Non-reassuring fetal status
- Maternal hemodynamic instability
- Not in active labor with moderate/severe abruption
- Correct coagulopathy pre-op if possible
- Have blood products in OR
- Path rejoins step 06Shared downstream outcome
12Action Vaginal Delivery
If stable and progressing rapidly
- Amniotomy to accelerate labor
- Continuous fetal monitoring
- Prepare for PPH (uterus may not contract well)
- Operative vaginal if needed to expedite
- Active management of third stage
- Path rejoins step 06Shared downstream outcome
- Path rejoins step 10Shared downstream outcome
13Action If Fetal Demise
Focus on maternal stabilization
- Confirm fetal death by ultrasound
- DIC common with fetal demise - check labs
- Correct coagulopathy before delivery
- Vaginal delivery often possible
- Induction with oxytocin or prostaglandins
- Cesarean for maternal indications only
- Path rejoins step 06Shared downstream outcome
