A case of diffuse alveolar hemorrhage after tonsillectomy -A case report-

Area of Science:

• Pulmonology
• Anesthesiology
• Critical Care Medicine

Background:

• Diffuse alveolar hemorrhage (DAH) is a critical condition characterized by bleeding into the lung's air sacs.
• The thin blood-gas barrier, essential for gas exchange, is vulnerable to mechanical stress from increased capillary pressure, particularly during general anesthesia.
• Certain conditions, including mechanical stress from inhaled gases during anesthesia, can precipitate DAH.

Purpose of the Study:

• To report a case of inferred postoperative diffuse alveolar hemorrhage (DAH).
• To explore the potential link between chronic snoring, alveolar damage, and the onset of DAH following intubation.

Main Methods:

• Case report of a 25-year-old male patient experiencing acute respiratory symptoms post-tonsillectomy.
• Clinical observation of symptoms including severe cough and hemoptysis after endotracheal tube removal.
• Medical management with antihemorrhagic agents and antibiotics.

Main Results:

• The patient developed acute cough and hemoptysis after tonsillectomy under general anesthesia.
• No intraoperative complications or significant bleeding were noted during the surgery.
• The patient recovered within one week with conservative medical treatment.

Conclusions:

• Chronic snoring may have caused pre-existing alveolar damage, predisposing the patient to DAH.
• Intubation during general anesthesia is inferred as the trigger for DAH in this case.
• The patient experienced a benign clinical course with spontaneous regression of symptoms following medical intervention.
