NCT03688529

Brief Summary

To record the digital data from monitoring instruments (standard patient monitor) containing cardiovascular system information, and from depth-of-anesthesia monitoring modules (Bispectral index, Entropy module, Surgical Plethysmography Index, Analgesia Nociception Index) containing neurological system information captured in the patient monitor, as well as the physiological data regarding anesthetic dosage, respiratory gas analysis and the standard monitoring requirement of anesthesia. The investigators also record the precise time points of detail surgical steps during the shoulder arthroscopic surgery. Clinical data collected from these monitoring instrument will be used to gain more understanding of the complex interaction between anesthetic effect, surgical procedure, autonomic response and drug modeling. The goal is to obtain the performance of each monitoring index in detail surgical steps.

Outcome Measures

Primary Outcomes (1)

  • Correlation of the instantaneous effects and accumulative noxious effects of surgical steps with quantitative transient bradycardia indices: high frequency power, low frequency power, and the low-to-high ratio

    Frequency power will be calculated using time-frequency analysis technique. The unit of high frequency power and low frequency power is millisecond square. There is no unit for the ratio. Both absolute change and relative change will be calculated. These indices will be compared with physiological data from patient monitoring instrument also. Range of Spearman correlation is -1 to 1 and Range of prediction probability is 0.5-1.

    For each surgical events (skin incision, dissection... ), time frame will be one minute before the event to one minute afterward

Secondary Outcomes (1)

  • Pharmacological modeling of epidemiological factors and anesthetic factors to physiological data from patient monitoring instrument

    The intra-operative period which mostly lasts less than two hours, the duration of general anesthesia
