Primary Outcome Measures:
  • Intraoperative blood loss [ Time Frame: End of surgery (last suture) ] [ Designated as safety issue: No ]
    Intraoperative blood loss as estimated from surgical drain and sponges.


Secondary Outcome Measures:
  • Calculated blood loss [ Time Frame: 24 hours after end of surgery. ] [ Designated as safety issue: No ]
    Calculated blood loss at 24 h after end of surgery.


Other Outcome Measures:
  • Drug side effects [ Time Frame: During surgery (from start of procedure to last suture) ] [ Designated as safety issue: Yes ]
    Side effects causing discontinuation the study drug.

Arms Assigned Interventions
Experimental: Adrenaline
Intraoperative low-dose adrenaline infusion
 Drug: Adrenaline
Adrenaline infusion 0.05 microgram / kg / minute
Other Name: Ephinephrine
Placebo Comparator: Placebo
Placebo: Isotonic Saline
 Drug: Placebo
Intraoperative isotonic saline infusion as placebo for adrenaline.

Detailed Description:

Hip arthroplasty is associated with bleeding, anemia and the need for allogeneic transfusion. Administration of low-dose adrenaline activates the coagulation system and may decrease intraoperative and immediate postoperative bleeding. Thus, the aim of this study is to evaluation whether intraoperative IV-administration of low-dose adrenaline reduces bleeding in elective total hip arthroplasty.
