Paediatric post op tonsil bleed
Apr 13, 2026
A child presenting with bleeding after a tonsillectomy can feel deceptively stable. They may be sitting up, talking, even comfortable. But this is a clinical moment that can change quickly, and it calls for a high level of awareness and readiness.
Post-tonsillectomy haemorrhage most often occurs several days after surgery as the healing tissue separates. This can expose underlying vessels, leading to bleeding that may be intermittent or sudden. Children frequently swallow blood, so what you see is rarely the full picture. Alongside blood loss, the real risk sits in airway compromise.
- 🩸 Any bleeding, even if settled, must be treated as significant
• 🪑 Sit the child upright and leaning forward to reduce aspiration risk
• 💉 Secure IV access early and prepare for fluid resuscitation
• 👃 Have suction ready as blood can rapidly pool in the airway
• 📞 Escalate early to ENT and anaesthetic teams
Observation is critical. A child who has stopped bleeding is still at risk of rebleeding, sometimes without warning. Subtle signs like repeated swallowing, pallor, tachycardia, or restlessness may be early indicators of deterioration.
In practice, this is about staying one step ahead. Prepare your airway equipment, create a calm but ready environment, and involve senior support early. Avoid delays, even if things appear stable.
The clinical takeaway is clear. There is no such thing as a minor tonsil bleed. Every presentation deserves vigilance, preparation, and respect for how quickly things can change.
