- Primary Outcome Measures
Name Time Method correlation between left-sided double lumen endobronchial tube depth and height gender tracheal length After induction of anesthesia and positioning the patients in lateral decubitus DLT depth
- Secondary Outcome Measures
Name Time Method formulate a formula to estimate the optimal insertion depth of left-sided double lumen endobronchial tube based on the patient s characteristics After induction of anesthesia and positioning the patients in lateral decubitus DLT depth,compare the new predicted left-sided double lumen endobronchial tube depth formula with the preexisting formulae After induction of anesthesia and positioning the patients in lateral decubitus DLT depth
