The aim is to determine if the use of infiltration with an adrenalin solution in the operative field of Total Hip Arthroplasty (THA), allays a significant reduction of the cumulated volume of bleeding (pre and post operative) without increasing the per and post operative risks. At the same time, the effect on the post operational pains is evaluated.
This prospective randomized study compares a population receiving a local anaesthetic (ropivacaine, adrenalin and physiological serum) in the operative field to a population undergoing a standard protocol. The cumulated volume of bleeding per and post operative are recorded and complete blood count (CBC).
