Summary
In practice ambulatory orthopedic surgery, one of the problems of most difficult solution is
adequate control of postoperative analgesia. Pain is a frequent cause of consultation and
unscheduled readmissions in this group of patients.
The use of continuous peripheral nerve blocks are an effective tool in postoperative
analgesia.
In this connection, most of the studies of continuous infusions of local anesthetics by
perineural catheters have been made with bupivacaine, levobupivacaine, and ropivacaine
However, it has been found that lidocaine action lasts less, has lower cost and is less toxic
than longer-acting agents.
The investigators aim is to compare the effectiveness of lidocaine versus bupivacaine
continuous popliteal sciatic blockade ambulatory elastomeric pump.
