Utjecaj prijeoperacijske blokade perifernih živaca na poslijeoperacijsku bol i ranu mobilizaciju bolesnika nakon rekonstrukcije prednje ukrižene sveze koljenskoga zgloba

Anterior cruciate ligament (ACL) reconstruction is one of the most frequent arthroscopic procedures done in orthopaedic surgery, and also one of the most painful. Although arthroscopy is associated with less tissue trauma, pain during the first 24-postoperative hours is still a clinical concern. Standardized methods with central analgesics in continuous parenteral infusion were associated with nausea, vomiting and longer hospital stay. The aim of this study is to investigate the success rate of preoperative ultrasound-guided peripheral nerve blockade using low dose of local anesthetic. For this purpose, 150 patients scheduled for the ACL reconstruction will be included in this study. They will be uniformly anesthetized and randomized between three groups: intravenous and two models of regional analgesia. It is expected to find the difference in success rate between the three analgesia techniques and their influence on postoperative recovery and early mobilization.
