Pathway Overview
13 steps
Algorithm Steps
13 total
01Start 02Decision Assess Bleeding Severity
Quantify chest tube output and clinical status
- Measure chest tube output hourly
- Trend hemoglobin/hematocrit
- Assess hemodynamic stability
- Check for signs of tamponade
03Warning ⚠️ MASSIVE BLEEDING
>400 mL/hr or hemodynamic collapse
- Activate massive transfusion protocol
- Prepare for immediate re-exploration
- Call cardiac surgery STAT
04Action Return to OR
Surgical re-exploration
- Median sternotomy re-opening
- Evacuate clot
- Identify and control surgical bleeding
- Irrigate and reclose
- Continue hemostatic resuscitation
05Outcome Bleeding Controlled
Continue routine post-op care
06Warning ⚠️ Rule Out Tamponade
Sudden drop in chest tube output + hypotension = assume tamponade until proven otherwise
07Action Significant Bleeding
>200 mL/hr for 2+ hours
- Check chest tubes for patency - milk gently
- Warm patient to 37°C
- Correct acidosis
- Obtain coagulation labs + viscoelastic test
08Action Coagulation Assessment
Use viscoelastic testing if available
- TEG or ROTEM preferred over conventional tests
- Check: PT/INR, aPTT, fibrinogen, platelets
- Consider heparin rebound (protamine re-dose)
- Assess platelet function if on antiplatelet agents
09Action Correct Coagulopathy
Guided by TEG/ROTEM or conventional labs
- Fibrinogen <1.5 g/L: Fibrinogen concentrate or cryoprecipitate
- Platelets <100 × 10⁹/L: Platelet transfusion
- INR >1.5: PCC or FFP (PCC preferred)
- Heparin rebound: Protamine 25-50 mg
- Consider desmopressin (DDAVP) 0.3 mcg/kg
- Tranexamic acid if ongoing fibrinolysis
10Decision Re-exploration Indicated?
Assess need for surgical intervention
- Indications for re-exploration:
- • >400 mL in first hour
- • >200 mL/hr for 4 hours despite correction
- • Sudden cessation of drainage (clot)
- • Hemodynamic instability
- • Signs of tamponade
- Path rejoins step 04Shared downstream outcome
11Action Continue Medical Management
If bleeding controlled with correction
- Serial hemoglobin monitoring (q2-4h)
- Continue warming
- Maintain Hb >7-8 g/dL (>8-9 if ongoing bleeding)
- Watch for delayed tamponade
- Path rejoins step 05Shared downstream outcome
12Action Transfusion Targets
Restrictive approach when stable
- Hemoglobin trigger: 7-8 g/dL (stable)
- Higher threshold if active bleeding/ischemia
- Avoid over-transfusion (increased complications)
- Use cell salvage when available
13Action Moderate Bleeding
100-200 mL/hr
- Monitor closely
- Check coagulation status
- Optimize temperature and pH
- Review anticoagulation status
- Path rejoins step 08Shared downstream outcome
