ABSTRACT
Objective To investigate the effects of two different methods of double-lumen endotracheal intubation in minimally invasive thoracoscopic surgery. Methods Based on different methods of endotracheal intubation,120 patients with bullae and spontaneous pneumo-thorax were randomly divided into the single left intubation group (60 cases) and the left and right intubation group (60 cases). The opera-tion time,blood loss,chest drainage volume,the time of pulmonary air leaks,white blood cell count and other indexes of the two groups were evaluated. Results The proportion of patients whose atelectasis degree was over 50% in the left and right intubation group occupied 48%, and it occupied 32% in patients whose atelectasis degree was over 70%. While the corresponding data in the single left intubation group were 5. 00% and 93% respectively. The differences were statistically significant (P<0. 01). The operative time and postoperative indicators of the single left intubation group were more significantly lower than those in the left and right intubation group. Conclusion The left double-lu-men endotracheal intubation has obvious advantages in maintenance and control of lung expansion and pulmonary ventilation during surgery, and it should be used in video assisted thoracoscopy surgery.
