Brief Summary

Co-administration of propofol and remifentanil is considered to be an ideal total intravenous anesthesia technique, which is widely used in induction and maintenance of general anesthesia. Remifentanil and propofol can be mixed in polypropylene syringes for one hour with a remaining concentration of 91% in small concentrations of remifentanil. However, delivery of remifentanil-propofol mixture by target-controlled infusion(TCI) for general anesthesia in surgical procedure has not been described. Breast cancer surgery ( including modified radical mastectomy and breast-conserving surgery) is a less time-consuming procedure for patients with breast cancer with one-hour duration in our hospital. This pilot study was to examine the merit of remifentanil-propofol mixture as a GA regimen for breast cancer surgery.

  • Mean blood pressure

    at 5 minute intervals perioperatively throughout the procedure in an average of 60 minutes

  • Heart rate

    at 5 minute intervals perioperatively throughout the procedure in an average of 60 minutes

Study Arms (2)

Mix infusion using single TCI pump

EXPERIMENTAL

participants receive total intravenous anesthesia with remifentanil-propofol mixture by single TCI pump infusion

Combination Product: Remifentanil-propofol mixture

Separate infusion using two TCI pumps

NO INTERVENTION

participants receive total intravenous anesthesia with remifentanil and propofol separately by two TCI pumps infusion

Interventions

Participants receive total intravenous anesthesia with remifentanil-propofol mixture by single TCI pump in intervention group. All TCI target concentration adjustments or extra bolus of propofol or remifentanil during operation were based on BIS and ANI monitor.
