About This Trial
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.
