Brief Summary:
The investigators hypothesized that both propofol and desflurane would decrease the regional oxygen saturation (rSO2) but propofol is likely to reduce rSO2 more than sevoflurane when patients are raised to the sitting position.

Condition or disease Intervention/treatment Phase
Cerebral Ischemia Drug: propofol Drug: Desflurane Drug: alfentanil Drug: Rocuronium Not Applicable

Detailed Description:
The investigators hypothesized that both propofol and desflurane would decrease the rSO2 but propofol is likely to reduce rSO2 more than sevoflurane when patients are raised to the sitting position. Therefore, the purpose of this study was to investigate the effect of desflurane and propofol on rSO2 values during the beach chair position for shoulder arthroscopy.

Arm Intervention/treatment
Experimental: Desflurane
anaesthesia was induced with thiopental sodium 2 mg kg-1, alfentanil 10 μg kg-1 and rocuronium 0.6 mg kg-1. Anesthetic maintenance by desflurane
Drug: Desflurane
anaesthesia was maintained by desflurane 4-7vol%
Other Name: Des

Drug: alfentanil
administration of alfentanil 10 μg kg-1 for anesthetic induction
Other Name: alf

Drug: Rocuronium
administration of rocuronium 0.6 mg kg-1 for anesthetic induction
Other Name: roc

Active Comparator: propofol
anaesthesia was induced with the effect-site concentration of propofol 5.0 μg ml-1, alfentanil 10 μg kg-1, and rocuronium 0.6 mg kg-1. A commercially available target controlled infusion (TCI) pump (Orchestra®, Fresenius Vial, France) was used and the pharmacokinetic set used to calculate target effect-site concentrations for propofol was Schnider and colleagues' model
Drug: propofol
anaesthesia was induced with the effect-site concentration of propofol 5.0 μg ml-1 mainly.

Drug: alfentanil
administration of alfentanil 10 μg kg-1 for anesthetic induction
Other Name: alf

Drug: Rocuronium
administration of rocuronium 0.6 mg kg-1 for anesthetic induction
Other Name: roc




Primary Outcome Measures :
  1. Regional Cerebral Oxygen Satuation (rSO2) [ Time Frame: 1, 3, 5, 7, and 9 min after the beach chair position ]
    definitive values of regional cerebral oxygen saturation(rSO2,%) values are described as mean (SD)
