Treatment of Post-Tonsillectomy Bleeding
Immediate surgical re-exploration in the operating room is the definitive treatment for significant post-tonsillectomy bleeding, with direct visualization and cauterization of bleeding vessels under general anesthesia. 1, 2
Initial Assessment and Triage
Categorize the bleeding temporally:
- Primary hemorrhage (within 24 hours): Incidence 0.1-2.2%, typically related to surgical technique and reopening of blood vessels 3, 1, 2
- Secondary hemorrhage (after 24 hours, typically days 5-10): Incidence 0.1-3%, usually caused by eschar sloughing during healing 1, 2
Assess bleeding severity immediately:
- Active bleeding requiring intervention versus minor bleeding that has stopped 4
- Hemodynamic stability (blood pressure, heart rate) 5
- Airway patency and respiratory status 1, 6
Definitive Surgical Management
Return to the operating room for surgical re-exploration is required for any significant bleeding 1, 2. This involves:
- Direct visualization of the tonsillar fossa under general anesthesia 1, 2
- Cauterization of identifiable bleeding vessels 1, 2
- Suturing of faucial pillars if diffuse oozing persists 7
Critical pitfall: Avoid using absorbable cellulose hemostatic dressings (e.g., Surgicel) incorporated into closures, as dislodgement can cause airway obstruction 7
For refractory cases with life-threatening hemorrhage: Ligature of the external carotid artery (LECA) is the method of choice when standard surgical control fails 8. This is rare but may be necessary when bleeding is excessive despite operative intervention 8.
Airway Management
If the patient has an endotracheal tube in place: Maintain intubation until complete hemostasis is confirmed, airway edema has subsided, and the patient is fully awake and able to protect their airway 1
High-risk patients for respiratory complications (5.8-26.8% incidence in OSA patients) include children under 3 years, those with severe OSA, and those with craniofacial disorders 6, 2. These patients require continuous pulse oximetry monitoring 6
Medical Management Considerations
Avoid aspirin postoperatively as it increases hemorrhage risk 6, 2
Non-aspirin NSAIDs (ibuprofen, diclofenac) are safe and do not significantly increase bleeding risk, though consider temporarily withholding them in the immediate post-bleeding period 3, 1, 6, 2
Perioperative antibiotics do not reduce hemorrhage rates and should not be used routinely for this purpose 6, 2
Tranexamic acid is FDA-approved as an antifibrinolytic for short-term use (2-8 days) to reduce or prevent hemorrhage in patients with hemophilia undergoing dental extraction 9. While not specifically studied for routine post-tonsillectomy bleeding, it may be considered in refractory cases, though this is off-label use.
Post-Intervention Monitoring
Continue monitoring for:
- Respiratory complications, which occur at higher rates in OSA patients 1, 2
- Signs of rebleeding (fresh blood, hemodynamic instability) 6, 2
- Adequate hydration and oral intake 6
Warning signs requiring immediate attention include fresh bleeding, respiratory distress, severe pain, and signs of dehydration 6, 2
Risk Factors to Document
Patient factors associated with increased bleeding risk:
- Male gender 2
- History of recurrent acute tonsillitis (3.7% bleeding rate) 6, 2
- Previous peritonsillar abscess (5.4% bleeding rate) 6, 2
- Age ≥12 years 3
- Abnormal preoperative clotting studies 5
- Elevated postoperative blood pressure 5
Surgical technique factors:
- Hot techniques (diathermy, coblation) increase secondary hemorrhage risk 3-fold compared to cold steel tonsillectomy 3, 6, 2
- Cold steel with bipolar diathermy has 1.5 times higher secondary hemorrhage risk than cold steel with ties/packs alone 6
Quality Improvement Documentation
Document thoroughly: Timing (primary vs. secondary), interventions required, blood transfusion needs, and outcomes 1, 2
Track your bleeding rates annually: Clinicians should determine their rate of primary and secondary post-tonsillectomy bleeding at least annually for quality improvement 3, 2
Critical Mortality Data
Mortality from post-tonsillectomy hemorrhage accounts for approximately one-third of tonsillectomy-related deaths, with overall mortality rates of 1 per 2,360 in inpatient settings and 1 per 18,000 in ambulatory settings 6, 2. This underscores the life-threatening nature of this complication and the need for aggressive surgical management.
