The Effect of Administration of Low Dose Adrenaline During Surgery on Bleeding During Hip Surgery
The purpose of this study is to evaluate the effect of intraoperative administration of low-dose adrenaline on intraoperative blood loss in patients undergoing hip surgery.

|Official Title:||The Effect of Intraoperative Low Dose Adrenaline on Bleeding in Total Hip Arthroplasty - a Randomized Placebo-controlled Trial|
- 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.
- 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.
- 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.

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