15 steps
Algorithm Steps
15 total
01Start 02Action Immediate Triage - ESI Level 2
Place in trauma/resuscitation bay. Position upright to reduce aspiration risk. Suction available. NPO. Large bore IV access.
- Deaths from AIRWAY COMPROMISE, not exsanguination
- Have difficult airway equipment ready
- Call ENT immediately
03Decision Active Bleeding Severity?
Assess: Active bleeding vs history of bleed that stopped. Signs of significant blood loss: pallor, tachycardia, hypotension, altered mental status.
04Warning ⚠️ Massive/Active Hemorrhage
Apply direct pressure with gauze soaked in 1:10,000 epinephrine or oxymetazoline. Suction clots. Activate massive transfusion protocol if hemodynamically unstable.
05Action Labs & IV Access
CBC, BMP, PT/INR, PTT, Type and Crossmatch. Large bore IV x2. Crystalloid bolus if hypotensive. Consider blood products early.
06Action Temporizing Measures
While awaiting ENT: Hydrogen peroxide gargles (3% diluted 1:3 with water) for slow bleeds. Ice water gargles. Tranexamic acid (TXA).
- TXA nebulized: 250mg if <25kg, 500mg if >25kg
- TXA IV: 10-15mg/kg (max 1g)
- H2O2 gargles can stop slow bleeds
- Keep patient calm to prevent re-bleeding
07Action ENT Bedside Assessment
ENT examines tonsillar fossa with headlight and tongue depressor. Identifies bleeding source. May attempt bedside cautery with silver nitrate if visible bleeding point.
08Decision Bleeding Controlled?
Has bleeding stopped with conservative measures and/or bedside cautery?
09Warning ⚠️ Operative Management Required
OR for suction cautery, pillar suturing, or figure-8 sutures. Consider external carotid ligation for life-threatening refractory bleeding. IR embolization if available.
10Decision Intubation Needed?
Indications: altered mental status, massive ongoing bleeding, inability to protect airway, respiratory distress. Use RSI with experienced provider. Have surgical airway ready.
11Outcome Post-Operative Care
ICU if intubated or significant blood loss. Hemoglobin monitoring. Transfuse as needed. Anticipate 24-48h observation post-op.
12Action Observation Period
All patients with PTH (even if bleeding stopped) should be admitted for 12-24 hour observation. NPO. Serial hemoglobin checks. ENT follow-up.
- Keep NPO for at least 6 hours
- IV hydration
- Clear liquid diet when stable
- Strict return precautions
13Decision Safe for Discharge?
No recurrent bleeding for 12-24 hours. Tolerating PO. Stable hemoglobin. Reliable follow-up. Caregiver understands return precautions.
14Outcome Discharge with Precautions
Soft/cool diet. Avoid strenuous activity for 2 weeks. Return IMMEDIATELY for any further bleeding. ENT follow-up in 1-2 weeks.
15Outcome Admit for Monitoring
Continue observation. Serial hemoglobin. May need repeat OR if rebleeding. Consider coagulopathy workup if recurrent.
