An interventional study of Semi-closed loop infusion system tactic. and Routine infusion therapy tactic in Hip Osteoarthritis, sponsored by Vilnius University. Completed. Open to participants aged 50 Years to 85 Years. Per ClinicalTrials.gov, last updated 2017-08-28.
Sponsored by Vilnius University · Not applicable, Interventional, and Treatment
Success of the hip arthroplasty depends on the measures that optimize perioperative conditions.It is planned to evaluate semi-closed loop system in the hip arthroplasty surgery.
Success of the total hip arthroplasty depends on the measures that optimize perioperative conditions. They increase the emotional stress of the staff and error probability. It is planned to evaluate semi-closed loop infusion system, its adaption for infusion application's influence to near and far treatment outcomes done by prospective randomized clinical trial. This is done by performing total hip arthroplasty. It's expected to evaluate the semi-closed loop system's influence on the doctor's emotional tension during the decision making.
Exclusion Criteria:
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.
Routine infusion therapy tactic
Procedure: Routine infusion therapy tactic
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.
Routine re-hydration bolus before surgery. Routine treatment of hypotension. Routine treatment of anemia.
