**2. Rationale for regional anesthesia use in reconstructive surgery**

Regional block offers many advantages of an ideal analgesic. Specific and unique advantages include superior analgesia, decreased postoperative delirium and psychosis, preserved sleep cycle, attenuation of stress response to injury, decreased nausea and vomiting, decreased posttraumatic chronic pain syndrome, and reduced systemic side-effects of opioids. Administration of regional anesthesia averts the risk of airway complications associated with airway instrumentation during general anesthesia and positive pressure ventilation, such as failure to secure airway, aspiration pneumonia and aggravation of cervical cord injury. Anesthesiologists encounter patients with critical trauma at various times during ongoing care, from prehospital resuscitation, stabilization in the emergency department, the management of the anesthesia and the intensive care unit, to the pain treatment service. Each stage offers the opportunity to provide regional anesthesia to trauma patients [6].
