During the past 20 years, video-assisted thoracoscopic surgery (VATS) has been an important minimally invasive tool. In order to further reduce its invasiveness, non-intubated spontaneous breathing general anesthesia via a laryngeal mask (LMA) was used in a variety of thoracic procedures. The objective of this study is to evaluate the safety and feasibility of this advantageous technique.
From March 2013 till now, 23 patients with lung or pleural disease were managed by VATS under spontaneous breathing general anesthesia with LMA without using muscle relaxants.

The mean operative time was 40 minutes (range, 15-90 minutes). The values of lower oxygen saturation and peak end-tidal carbon dioxide tension were 95% and 50 mmHg, respectively. No mask displacement occurred. No conversion to endotracheal anesthesia was required, whereas one patient required conversion to mini thoracotomy. The level of technical feasibility was excellent in 12 cases and good in 11 cases. Mortality as well as morbidity rates were zero. Mean postoperative stay was 2.6 days.
It seems that VATS is safe and feasible under non-intubated spontaneous breathing anesthesia with LMA. A confident manipulation of lung parenchyma is allowed preventing from cough, pain, or panic attack described for awake epidural anesthesia, as well as avoiding the risks of tracheal intubation and mechanical ventilation.
