NCT02116985

Brief Summary

Laparoscopic Cholecystectomy applied to Artificial pneumoperitoneum and the extent of Surgical stimulation cause the wave of hemodynamics increase vigorously, which make it difficult to judge the depth of anesthesia according to traditional hemodynamics index such as heart rate and blood pressure.In case of this, the investigators design this research to study the Closed-Loop Target Controlled Infusion to anaesthesia of individualization guided by a Narcotrend index monitor in Laparoscopic Cholecystectomy.

Outcome Measures

Primary Outcomes (1)

  • The total dose of propofol and remifentanil

    record the total dose of propofol and remifentanil from the beginning to the end of anesthesia.

    within two hours from the beginning to the end of the propofol and remifentanil

Study Arms (2)

Dual-Loop TCI

EXPERIMENTAL

the controller in the current study measures and calculates the error(NI error),which is the difference between the set point(NI=36)and the measured NI.If the NI error is different from 0,the controller determines a new propoflo and/or remifentanil concentration.

Device: Dual-loop TCI

manual

PLACEBO COMPARATOR

the investigator modified the effect-site target concentrations of both drugs without minimum or maximum concentration limits without using the Narcotrend monitor only depend on the experience of anesthesiologist.
