Summary

intends to evaluate the feasibility and security issues of univent bronchial blockers outside the single lumen endotracheal tube for one- lung ventilation in left thoracic surgery patients.

Detailed description

One-lung ventilation is desirable for Several clinical procedures, such as thoracic,pulmonary, and cardiac surgery to facilitate lung exposure for these surgical procedures by collapsing the lung and most commonly used device is the double-lumen tube (DLT) for this surgical procedures.Bronchial blockers (BBs), such as univent tube with an bronchial Blocker, has more advantages than the double-lumen tube: no need exchange tube when mechanical ventilation is required postoperative, easier insertion,less postoperative sore throat (ST) and hoarseness. However, BBs requires more time for placement and more difficult to position, especially patients undergoing left-side thoracic surgery. So, this study intends to evaluate the feasibility and security issues of univent bronchial blockers outside the single lumen endotracheal tube for one- lung ventilation in left thoracic surgery patients.

Interventions

Type	Name	Description
DEVICE	Extraluminal use of Univent bronchial Blocker	Patients assigned to the Extraluminal use of Univent Blocker group were first inserted Univent bronchial Blocker into the glottis via direct laryngoscopy then advanced the Blocker to the target bronchus until slight resistance was encountered.A conventional tracheal tube with appropriate size was intubated via direct laryngoscopy into the appropriate depth, inflating the tracheal tube cuff, and fixing the tube firmly at the patient's mouth with cloth tape . So the Univent Blocker Extraluminal of the endotracheal tube,then the fibreoptic bronchoscopy was inserted into the tracheal tube and guided bronchial blocker cuff to the target main bronchus under direct vision
DEVICE	Innerluminal use Univent bronchial Blocker	Patients in Innerluminal use of Univent Blocker group: When the endotracheal tube had been intubated via direct laryngoscopy, the bronchial blocker was advanced Innerluminal of the endotracheal tube and directed into the right or left mainstem bronchus, then the fibreoptic bronchoscopy was inserted into the tracheal tube. After further pushing and twisting, the bronchial blocker tube will move into the mainstem bronchus under direct vision by FOB.the tracheal tube cuff is inflated with the tube being fixed firmly at the patient's mouth with cloth tape
