Abstract
Silent lung is an extreme and life-threatening manifestation of severe bronchospasm, characterized by marked attenuation or complete disappearance of bilateral breath sounds and abrupt loss of the end-tidal carbon dioxide (EtCO₂) waveform. This condition may rapidly progress to severe hypoxemia and cardiac arrest. Early recognition, prompt diagnosis, and standardized intervention are critical for reversing bronchospasm and preventing catastrophic perioperative complications.
Current clinical studies mainly focus on the prevention of common perioperative airway adverse events, whereas standardized and systematic management protocols specifically for extubation-induced silent lung remain lacking. Herein, we report a case of silent lung triggered by coughing during extubation in an elderly male patient following right knee arthroplasty. Timely anesthetic intervention resulted in successful resuscitation and smooth extubation. The patient was transferred uneventfully to the general ward, without subsequent pulmonary complications or prolonged hospitalization.
This case supplements current clinical experience regarding silent lung management and provides a reference for individualized anesthetic care in high-risk elderly patients with underlying cardiovascular and airway diseases.
