title: Continuous peripheral nerve block in forearm for severe hand trauma.
abstract: We studied the use of a continuous peripheral nerve block (CPNB) in the distal forearm and wrist immediately after emergent surgery for severe hand trauma in 22 hands. After emergent surgery, a 2-3 cm longitudinal incision was made at the distal forearm and an 18-gauge catheter was inserted along the peripheral nerves. All patients received postoperative analgesia by continuous infusion of 0.2% ropivacaine at 2 ml/h for seven to 21 days. Pain score remained low during postoperative period and only a small number of analgesic rescues were needed. There were no major complications related to the CPNB and one patient showed mild superficial infection at the insertion site that immediately recovered after catheter removal. This method provides good postoperative analgesia without loss of motor function in extrinsic hand muscles and should be considered as a postoperative pain management for severe hand trauma.
