regional anesthesia(English)
- has become an integral and common component of both intraoperative anesthesia and postoperative analgesia in infants and children. Advantages of regional blockade include the reduction of general anesthetic dose requirements, effective blunting of hemodynamic and autonomic responses, and excellent postoperative analgesia with decreased requirement of systemic analgesics and their concomitant side effects. For many orthopedic operations, increasing use of peripheral nerve blockade permits the anesthesiologist to provide long durations of analgesia limited to the surgical site
