AANA Journal Course: update for nurse anesthetists--femoral nerve block and 3-in-1 block in anesthesia.

These blocks also may provide postoperative analgesia that may be a useful alternative to epidural or parenteral analgesia. Understanding the techniques of blockade, its appropriate applications, and the relevant anatomy may provide the anesthetist with a valuable alternative.
