Abstract

Background: The major limitations of widespread use of non-intubated thoracic surgery (NITS) is the fear of managing complications. Here we present our practice of converting from uniportal video-assisted thoracic surgery (VATS) NITS to open NITS in cases of surgical complications. Methods: The study period was from January 26, 2017, to November 30, 2018. Total intravenous anesthesia was provided with propofol guided by bispectral index, and the airway was maintained with a laryngeal mask with spontaneous breathing. Local anesthesia with 2% lidocaine at the skin incision, and intercostal and vagus nerve blockades were induced using 0.5% bupivacaine. For conversion with surgical indications, a thoracotomy was performed at the incision without additional local or general anesthetics. Results: In 160 complete NITS procedures, there were 145 VATS NITS and 15 open NITS (9 conversions to open NITS and 6 intended NITS thoracotomies). In the 15 open NITS cases (2 pneumonectomies, 1 bilobectomy, 1 sleeve lobectomy, 7 lobectomies, 3 sublobar resections, 1 exploration), the mean operative time was 146.7 (105-225) and 110 (75-190) minutes in the converted and intended open NITS groups, respectively. There were no significant differences between systolic blood pressure (P=0.316; 95% CI, ?10.469 to 3.742), sat O2% (P=0.27; 95% CI, ?1.902 to 0.593), or propofol concentration in the effect site (P=0.053; 95% CI, ?0.307 to 0.002) but significant differences in pulse (P=0.007; 95% CI, ?10.001 to ?2.72), diastolic blood pressure (P=0.013; 95% CI, ?9.489 to ?1.420) and in end-tidal CO2 (P=0.016; 95% CI, ?7.484 to ?0.952) before versus after thoracotomy, but there was no clinical relevance of the differences. Conclusions: For conversion with surgical indications during the VATS-NITS procedure, NITS thoracotomy can be performed safely at the site of the utility incision without the need for additional drugs, and the major lung resections can be performed through this approach.
