“…In adult patients of Asian descent, however, which comprises many individuals of shorter stature (<155 cm), patient height is not a good predictor of depth of insertion for a DLT [18]. An inadvertent deep insertion of a DLT can lead to serious complications, including rupture of the left mainstem bronchus [7].…”

“…Many previous studies have shown that the patient's height is correlated with the size and depth of the insertion of the DLT and that the height can be used to determine these values [5,[7][8][9]. In patients of a short stature (below 155 cm), however, the height value is not good predictor of the size and depth of the insertion of the DLT [2]. It is difficult to achieve successful OLV in these cases, and these patients are more susceptible to airway injuries [10,11].…”

“…When OLV is not properly achieved, it can affect not only the surgical outcome but also patient safety. The size and depth of the insertion of the DLT are important factors for successful OLV [2][3][4][5][6]. Many previous studies have shown that the patient's height is correlated with the size and depth of the insertion of the DLT and that the height can be used to determine these values [5,[7][8][9].…”

“…It is difficult to achieve successful OLV in these cases, and these patients are more susceptible to airway injuries [10,11]. Several studies have attempted to determine the depth of insertion and the size of the DLT in patients of a short stature [2,12]. Most studies which attempted to determine the optimal position of the DLT focused on the position of the DLT at the tracheal carina level.…”

Background:The size and depth of the double-lumen tube (DLT) are important for one-lung ventilation (OLV). In patients of a short stature, it is difficult to perform OLV successfully. We designed this study to evaluate the dimensions and margin of safety of the left main bronchi in patients of a short stature for appropriate OLV. Methods: Chest computed tomography (CT) scans of 241 patients (22 male, 219 female) of a short stature (height below 155 cm) were analyzed retrospectively. The diameters of the trachea (DT), the right and left main bronchi (DR and DL), and the lengths of the right and left main bronchi (LR and LL) were measured at the coronal section of the chest CT scans using a picture archiving communication system program. Results: There were no significant correlations between the heights and lengths of the right and left main bronchi. In addition, the ages and weights of the patients showed no significant correlations with the airway dimensions. The lengths of the bronchial lumen of the left-sided Mallinckrodt DLT show variations of 3 to 5.5 mm with tubes of identical sizes. The margin of safety is 13.8 ± 4.1 mm assuming that appropriately sized DLTs are inserted. Conclusions: For successful and safe OLV in patients of a short stature, anesthesiologists should consider the length of the main bronchus and the actual length of the bronchial lumen of the DLT.
