AI-Summary
What this Trial Is About
This study aims to propose a strategy for controlling the depth of anesthesia based on continuous and non-invasive monitoring of exhaled breath: BIS value during intravenous-inhalation combined anesthesia is predicted according to the real-time exhaled concentrations of sevoflurane and propofol, so as to achieve the depth of anesthesia management for patients who cannot use standard BIS. Furthermore, the relationship between anesthetic concentration and depth of anesthesia was analyzed in different subgroups.
