Outcome Measures

Primary Outcomes (2)

  • Response Surface Models

    Pharmacodynamic response surface model is a mathematic model which provides information about when and what extent the patient will response to a specific physiological condition (pain, respiratory depression, anesthesia depth….) in a given combination drug concentration pairs. The calculated plasma or effect concentration of specific medications will be used to train iteratively by non-linear regression to find the optimal parameters to construct a new response surface model. Then the model will be validated by the observation data to see the accuracy and efficacy of the model.

    10 seconds from once the anesthetics were terminated to 10 minutes after the time of each patient's wake up

  • Evaluation of Response Surface Model Predictions

    Model predictions were evaluated at the emergence period of moderate sedation or general anesthesia. Model predictions of OAA/S ranging from 0% to 100% were made every 10 seconds from once the anesthetics were terminated to 10 minutes after the time of each patient's wake up. Model predictions were compared with observations with graphical and temporal analyses

    10 seconds from once the anesthetics were terminated to 10 minutes after the time of each patient's wake up

Study Arms (2)

Brochoscopy

20 ASA Class II-III, aged 20-80 adult patients who require moderate sedation during bronchoscopy will be enrolled into this study. The moderate sedation will be performed only after patients' inform consents and approval of the institutional ethics committee. Patients with conditions such as neurological disorders, hearing impairment, history of habitual sedative medication and alcoholism will be excluded from this study.

ERCP

20 ASA Class II-III, aged 20-80 adult patients who require moderate sedation during ERCP will be enrolled into this study. The moderate sedation will be performed only after patients' inform consents and approval of the institutional ethics committee. Patients with conditions such as neurological disorders, hearing impairment, history of habitual sedative medication and alcoholism will be excluded from this study.
