Comparisons of Novel Double-lumen Endobronchial Tube for Blind Lung Isolation Technique With Conventional Double-lumen Endobronchial Tube in Patients Undergoing One-lung Ventilation
May 16, 2019 updated by: Yonsei University
The study is prospectively conducted on 190 patients aged between 20 and 85 years, American Society of Anesthesiologists (ASA) physical status I - III, undergoing one-lung ventilation for thoracic surgery.
Patients were randomly allocated into either control group (n = 95) or experimental group (n = 95) by a computerized randomization table.
The size of endobronchial tube is decided based on the diameter of left main bronchus measured on the CT finding of patients.
After induction of general anesthesia, in patients assigned to control group, endobronchial intubation is performed using conventional technique with left-sided double-lumen endobronchial tube (Shiley®, Covidien, Mansfield, MA, USA).
In experimental group, patients are intubated with novel double-lumen endobronchial tube (Ankor®,Insung Medical, Wonjou, S. Korea).
During intubation, the carina cuff of Ankor® is inflated after the tube is rotated 90º toward the left.
The tube is advanced until slight resistance is felt, then the carina cuff is deflated.
In both groups, fiberoptic bronchoscope is performed to evaluate the position of endobronchial tube after intubation.
If endobronchial tube is not in optimal position, the depth of tube is corrected to optimal position under guidance of fiberoptic bronchoscope.
Airway injury is confirmed using fiberoptic bronchoscope before extubation.
The success of endobronchial intubation, position of endobronchial tube, the corrected depth of endobronchial tube, time consumption for endobronchial intubation and complication of intubation such as airway injury, pain, and hoarseness are compared between two groups.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Optimal position of double-lumen endobronchial tube
Time Frame: 1 day (after intubation)
|
On fiberoptic bronchoscopic view after intubation, optimal position of double-lumen endobronchial tube is defined when the bronchial cuff of the tube is immediately below the tracheal carina and there is a clear view of the left subcarina with unobstructed left upper and lower bronchi.
|
1 day (after intubation)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The corrected depth of endobronchial tube
Time Frame: 1 day (after intubation)
|
The corrected depth of endobronchial tube is defined as the difference between the depth of endobronchial tube before and after the depth of tube is corrected to optimal position under guidance of fiberoptic.
