When properly and safely administered regional anesthesia can augment your limited supply of narcotics and ketamine. It can also preserve your patient's mental status while providing targeted pain relief. This can be accomplished using a nerve stimulator and the techniques found in the Military Advanced Regional Anesthesia and Analgesia Handbook. If you have a portable ultrasound machine and a little practice you can also use the techniques found in the videos made available in by the New York School of Regional Anesthesia.
