The use of regional anesthesia in orthopedics

Regional anesthesia has its place in the perioperative pain management of orthopedic patients. A reduction in postoperative mortality and morbidity with regional anesthesia is acknowledged for subsets of patient populations. Single shot and continuous applications are techniques for providing regional analgesia. Continuous infusion of local anesthetics with catheter techniques provides for uninterrupted postoperative analgesia.The combination of regional and general anesthesia reduces the consumption of systemic anesthetics.The side effects of opioid therapy are thereby reduced.The inhibition of intraoperative stress reaction, especially with epidural anesthesia, helps to prevent or lower unwanted metabolic changes. Patient contentment with analgesic quality differs with the technique with which the regional anesthesia is applied (PDA, PLEA, IVRA, peripheral block, i.a. injection), and the medication (LA,opioid) used.
