摘要：Endotracheal tube exchangers (ETTE) or airway exchange catheters (AEC) have been reported to be easy and safe to use.1,2 ETTE or AEC are thin, long, rigid, hollow tubes that can be left in place as a safety device to be used as a guide for reintubation when inserted through an endotracheal tube (ETT) before its removal. Alternatively, AEC can be used to insufflate oxygen, monitor end tidal CO2, or jet ventilation.3,4 Planned sequential extubation should be performed in a patient with difficult intubation as re-intubation becomes very difficult in such patients.1,3
A 23 yr old male patient presented with haematemesis for emergency distal splenorenal shunt. The patient had micrognathia and severely restricted mouth opening. We successfully intubated the patient with awake nasotracheal technique using Fibreoptic bronchoscope and successfully extubated sequentially using endotracheal tube exchangers (ETTE) and a nasopharyngeal airway on the next day of surgery.
