Primary Outcome Measures:
  • Recovery slope [ Time Frame: until 2 days after surgery ]
    Recovery slope is a marker of microcirculation. The tissue oxygen saturation (StO2) using InspectraTM StO2 (Hutchinson Technology Inc.,USA) will be recorded continuously. The InspectraTM StO2 probe will be placed on the skin of the thenar eminence and the blood pressure cuff will be wrapped around the arm. After performing vascular occlusion test, the recovery slope will be calculated by the software.

  • syndecan-1 [ Time Frame: until 2 days after surgery ]
    marker of glycocalyx degradation


Secondary Outcome Measures:
  • lactate [ Time Frame: until 2 days after surgery ]
  • StO2 (tissue oxygen saturation) [ Time Frame: until 2 days after surgery ]
  • Cytokine [ Time Frame: until 2 days after surgery ]
    Interleukin (IL)-1b, IL-6, IL-8, IL-10, TNF-a


Enrollment: 120
Study Start Date: March 2013
Study Completion Date: August 2014
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
