Using of the Endobronchial Double-Lumen Tube in the Thoracic Surgery Anesthesia

Abstract

Endobronchial double lumen tubes are extremely convenient in administering anesthesia in thoracic surgery. Qs/Qt, AaDO₂, PaO₂ and PACO₂ during ipsilateral lung ventilation by endobronchial double-lumen tubes were investigated in nine cases. The results revealed that for the prevention against elevation of Qs/Qt and hypoxemia, it is necessary to maintain FiO₂ at 1.0 during ventilation. The indications of the doublelumen tube in anesthesia for thoracic surgery include the following:
1) Severe emphysema
2) Wet lung cases (pyothorax, tuberculosis, lung abscess, bronchiectasis and etc)
3) Tension pneumothorax
4) Bronchoplastic surgery
