Repetitive postoperative extubation failure and cardiac arrest due to laryngomalacia after general anesthesia in an elderly patient: a case report

Abstract

The authors report a case involving an elderly patient who experienced repetitive perioperative cardiac arrest caused by laryngomalacia. The patient underwent surgery under general anesthesia; however, 2h after initial extubation, he experienced cardiopulmonary arrest. Return of spontaneous circulation was achieved by immediate resuscitation. Four hours later, a second extubation was performed without any neurological complications. However, 2h later, he experienced cardiopulmonary arrest again. Immediately after the third extubation, 12h after the second cardiopulmonary arrest, fiberoptic laryngoscopy revealed laryngomalacia. His respiratory condition stabilized after emergent tracheostomy. Laryngomalacia should be considered even in adult cases when signs of upper airway obstruction manifest after extubation.
