Brief Summary

The non-intubated video-assisted thoracic surgery (NIVATS) can avoid intubation-related complications and for a smoother postoperative recovery. Successful results are accumulating not only from anecdotal case reports of difficult and high-risk patients not suitable for an intubated general anesthesia. However, in spite of safety and feasibility, there were still three main concerns: 1. how to maintain spontaneous breathing with optimal anesthetic depth; 2. How to analyze the components of general anesthesia and regional anesthesia; 3.what's the benefits on the recovery and the risk of aspiration risk with NIVATS? The traditional monitor or methods such as BIS system, SpO2, and follow-up aspiration signs could not offer sufficient evidence to resolve the three main concerns. Recently, there have been many new methods to monitor these concerns. The density spectral array (DSA) BIS system could analyze the change of the anesthetic component. The ORI is a dimensionless index that reflects oxygenation in the moderate hyperoxic range (PaO2 100-200 mmHg).

Primary Outcomes (2)

  • The changes of Ce of propofol and remifentanil

    The changes of concentration of effective site (Ce) shown on TCI pump before and after intercostal nerve block in NIVATS and VATS groups
