Post-Tonsillectomy Hemorrhage Management

Algorithm Steps

1. ▶

   Start

   Post-Tonsillectomy Hemorrhage

   Patient with bleeding from throat after tonsillectomy. Primary: <24 hours. Secondary: 2-21 days post-op (most common day 5-10).

   1. ●

      Action

      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

         Decision

         Active Bleeding Severity?

         Assess: Active bleeding vs history of bleed that stopped. Signs of significant blood loss: pallor, tachycardia, hypotension, altered mental status.

         1. ⚠

            Warning

            ⚠️ 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.

            1. ●

               Action

               Labs & IV Access

               CBC, BMP, PT/INR, PTT, Type and Crossmatch. Large bore IV x2. Crystalloid bolus if hypotensive. Consider blood products early.

               1. ●

                  Action

                  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
                  1. ●

                     Action

                     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.

                        Decision

                        Bleeding Controlled?

                        Has bleeding stopped with conservative measures and/or bedside cautery?

                        1. ⚠

                           Warning

                           ⚠️ 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.

                           1. ◆

                              Decision

                              Intubation Needed?

                              Indications: altered mental status, massive ongoing bleeding, inability to protect airway, respiratory distress. Use RSI with experienced provider. Have surgical airway ready.

                                 Outcome

                                 Post-Operative Care

                                 ICU if intubated or significant blood loss. Hemoglobin monitoring. Transfuse as needed. Anticipate 24-48h observation post-op.

                        2. ●

                           Action

                           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

                              Safe for Discharge?

                              No recurrent bleeding for 12-24 hours. Tolerating PO. Stable hemoglobin. Reliable follow-up. Caregiver understands return precautions.

                                 Continue observation. Serial hemoglobin. May need repeat OR if rebleeding. Consider coagulopathy workup if recurrent.
