The first description of the use of a double-lumen endotracheal tube system for lung surgery was reported in 1962.<sup>26 Robertshaw F.L. Low-resistance double-lumen endobronchial tubes Br J Anaesth 1962 ;  34 : 576-579

This article discusses most common tubes used for lung isolation: left- and right-sided double-lumen endotracheal tubes<sup>21 Lewis J.W., Serwin J.P., Gabriel F.S. , e al.
