NCT01355900

Brief Summary

Different strategies of tourniquet application during elective primary total knee arthroplasty are thought to be associated with different outcomes. In that context, the study investigates different tactics in the search of optimal application of the tourniquet and the related fluid management during 24 perioperative hours.

Outcome Measures

Primary Outcomes (1)

  • Perioperative blood loss.

    The volume loading test is deployed for the comparison of perioperative hemoglobin in the standardized plasma dilution.

    Before (baseline) the surgery and 24 hrs postoperatively

Secondary Outcomes (11)

  • Wound healing

    Within 6 days postoperatively

  • Hemodilution

    Within 6 days postoperatively

  • Cardiac stroke volume

    Within 6 days postoperatively

  • Body temperature

    Within 6 days postoperatively

  • Pain (Visual Analog Scale)

    Within 6 days postoperatively

  • +6 more secondary outcomes

Study Arms (4)

I tourniquet tactic

OTHER

Use volume loading test twice (before surgery and 24hrs postoperatively). Total knee arthroplasty performed under tourniquet. Lower limb tourniquet inflation- before incision, deflation- after bone cement set.

Procedure: Total knee arthroplasty performed under tourniquet

II tourniquet tactic

OTHER

Use volume loading test twice (before surgery and 24hrs postoperatively). Total knee arthroplasty performed under tourniquet. Lower limb tourniquet inflation- before cement application, deflation- after bone cement set.

Procedure: Total knee arthroplasty performed under tourniquet

III tourniquet tactic

OTHER

Use volume loading test twice (before surgery and 24hrs postoperatively). Total knee arthroplasty performed under tourniquet. Lower limb tourniquet inflation- before incision, deflation- after wound closure

Procedure: Total knee arthroplasty performed under tourniquet

IV control group

OTHER

Do not use volume loading test. Total knee arthroplasty performed under tourniquet. Lower limb tourniquet inflation- before cement application, deflation- after bone cement set.

Procedure: Total knee arthroplasty performed under tourniquet

Interventions

Comparison of the different tourniquet tactics.
