Pathway Overview
12 steps
Algorithm Steps
12 total
01Start 02Action Recognize Warning Signs
Tamponade may present atypically post-sternotomy
- ACUTE (first 24-48h):
- • Sudden hypotension
- • Elevated/equalizing filling pressures
- • Sudden decrease/cessation of chest tube output
- • Tachycardia, low cardiac output
- DELAYED (>48h):
- • Insidious hypotension
- • Unexplained fever
- • Pleural effusions
03Decision Acute or Delayed Presentation?
First 48 hours vs later
04Warning ⚠️ ACUTE TAMPONADE
Often clot-related, may not be evident on echo
- Classic signs may be ABSENT
- Right-sided (RA/RV) compression most common
- Clot may be loculated
- Echo can miss posterior clot
05Decision Hemodynamic Collapse / Arrest?
Immediate vs urgent intervention
06Action IMMEDIATE BEDSIDE RESTERNOTOMY
Cardiac arrest or peri-arrest
- Do NOT delay for OR transfer
- Emergency sternotomy kit at bedside
- 5 essential items: scalpel, wire cutter, needle holder, sternal retractor, sucker
- Performed by surgeon or trained senior ICU staff
- No need for full sterile prep - use iodine-impregnated drapes
- Internal cardiac massage once chest open
07Action Surgical Exploration
Evacuate clot, control bleeding
- Evacuate all clot and effusion
- Inspect for surgical bleeding source
- Repair if identified
- Generous irrigation
- Consider leaving chest open (delayed closure)
08Outcome Hemodynamics Restored
Continue ICU monitoring
09Action Urgent OR Resternotomy
If hemodynamically tenuous but not arresting
- Call cardiac surgery STAT
- Mobilize OR team
- Volume resuscitation en route
- Avoid excessive fluid (may worsen tamponade)
- Consider inotropes for bridge
10Action Bridge Measures While Preparing
If any delay to OR
- Fluid bolus (cautious - 250-500 mL)
- Norepinephrine/epinephrine infusion
- Avoid bradycardia (tachycardia compensatory)
- Elevate legs
- DO NOT attempt pericardiocentesis (clot, not fluid)
- Path rejoins step 07Shared downstream outcome
11Action Delayed Tamponade
May have time for imaging
- Often fluid rather than clot
- Echo more reliable
- May develop over days
- Consider anticoagulation-related
- Path rejoins step 05Shared downstream outcome
12Warning ⚠️ NO Pericardiocentesis
Post-surgical tamponade is usually CLOT, not fluid. Pericardiocentesis will fail and delay definitive treatment.

Individual patient factors may require deviation from these recommendations.
Known Limitations
- Post-cardiac surgery tamponade may present atypically
- Echo may be limited by surgical changes and drains
- Pericardiocentesis often NOT feasible - loculated clot
- Requires immediate surgical capability
