Additional data collected included patients\u2019 demographics and DLT size used.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n There were 123 (68.7%) males and 56 (31.3%) females with an overall mean age of 33.3 \u00b1 16.3 years. Majority of the males (48.8%) used a size 39 Fr while females (46.4%) used a 35 Fr. There were weak correlations between DLT size with height (male:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.222; female:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.193), DLT size with weight (male:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.109; female:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.211), DLT size with TD (male:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.027); female:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.016), and DLT size with LMBD (male:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.222; female:\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.193). There was a good correlation between depth of DLT inserted with patient's height for both genders.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The appropriate size of the left-sided DLT could not be predicted based on patients\u2019 height, weight, tracheal or left main bronchus diameter alone in Asians; however, the depth of insertion of the tube was dependent on the height in both genders.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/0971-9784.197824","type":"journal-article","created":{"date-parts":[[2017,1,10]],"date-time":"2017-01-10T22:47:13Z","timestamp":1484088433000},"page":"28-32","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":20,"title":["Selection of an Appropriate Left-sided Double-lumen Tube Size for One-lung Ventilation among Asians"],"prefix":"10.4103","volume":"20","author":[{"given":"Siti Salwani","family":"Ideris","sequence":"first","affiliation":[{"name":"From the Department of Anaesthesiology and Intensive Care, Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhamad Rahimi","family":"Che Hassan","sequence":"additional","affiliation":[{"name":"From the Department of Anaesthesiology and Intensive Care, Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohd.
