Outcome Measures

Primary Outcomes (1)

  • The efficiency of semi-closed loop infusion system

    Determine the ratio of doctor's approved and rejected computer suggestions

    Before the surgery and 12 hrs postoperatively

Secondary Outcomes (7)

  • Perioperative blood loss

    Before (baseline) the surgery,during surgery and 24hrs postoperatively

  • Coagulation activity

    Before (baseline) the surgery and 24hrs postoperatively

  • Infused fluid and red blood cell volume

    Before the surgery and 24hrs postoperatively

  • Wound healing

    Within 6 days postoperatively

  • Dosage physical exercise sample

    Within 6 days postoperatively

  • +2 more secondary outcomes

Study Arms (2)

semi-closed system group

EXPERIMENTAL

Semi-closed loop infusion system tactic. Programmed iv fluid and blood infusion system ,,Belmont Rapid Infuser" and programmable syringe pump for adrenaline infusion.

Procedure: Semi-closed loop infusion system tactic.

control group

EXPERIMENTAL

Routine infusion therapy tactic

Procedure: Routine infusion therapy tactic

Interventions

Semi -closed loop infusion system tactic.Use volume loading test twice (before surgery and 12hrs postoperatively). Computer provides advisory hypotension treatment algorithm. Computer provides advisory anemia treatment algorithm. Programmed iv fluid and blood infusions system ,,Belmont Rapid Infuser" and programmable syringe pump for adrenaline infusion.

semi-closed system group

Routine re-hydration bolus before surgery. Routine treatment of hypotension. Routine treatment of anemia.

control group
