Age
20 Years to No maximum
Inclusion criteria
Inclusion criteria: 1 Patients who were older than 20 years 2 Underwent surgery required one-lung ventilation 3 Intubated with left-sided DLT size 35, 37 or 39 Fr. 4 The depth of DLT insertion was confirmed by fiberoptic bronchoscope - Successful lung separation during surgery without readjustment of the DLT position
Exclusion criteria
Exclusion criteria: 1 Intubated with right-sided DLT 2 Abnormal anatomy of airway, neck and chest wall 3 Anomaly that affected the patient height such as achondroplasia, gigantism, etc. 4 Previous surgery to the tracheal and the bronchus including sleeve lobectomy or pneumonectomy
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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
| Measure | Time frame |
|---|---|
| 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 | — |
