A case of pulmonary haemorrhage following jet ventilation for vocal cord surgery
1Department of Anaesthesia, Changi General Hospital, 2 Simei Street 3, Singapore 529889.
Introduction:
This case report highlights haemoptysis occurring after post-extubation laryngospasm.
Clinical Picture:
General anaesthesia using Sanders jet ventilation with a Benjamin tube was administered for a patient undergoing vocal cord biopsy. He developed laryngospasm followed by significant pulmonary haemorrhage and widespread crepitations in the lung.
Treatment:
Laryngospasm was aborted with assisted ventilation with oxygen 100% via bag and mask.
Outcome:
Oxygenation was well maintained with nasal prongs only postoperatively and haemoptysis resolved after 2 days.
Conclusion:
It is imperative to prevent laryngospasm from occurring and swift action must be taken to avoid pulmonary haemorrhage.
