title: [Use of peridural catheters in the treatment of postoperative pain after spinal instrumentated fusion--an experience report].
abstract: OBJECTIVE
  In a prospective randomized clinical study we investigated in a group of 20 patients after spinal instrumentation surgery the analgesic efficacy and the safety of epidural analgesia. Intraoperatively an epidural catheter was placed by the orthopedic surgeons for postoperative pain control.
  
  
  METHODS
  For epidural catheter analgesia a mixture of the local anesthetic ropivacaine and the opioid sufentanil was used with an initial bolus, followed by a continuous infusion and the possibility of patient-controlled bolus administration (PCEA). Pain-scores (VAS) were measured pre- and postoperatively at rest, and during active mobilization maneuvers like turning around in bed and standing. The neurological status, side effects, and complications were evaluated.
  
  
  RESULTS
  Mean pain-scores (VAS) were 3.8 pre-operatively at rest, after initiation of epidural analgesia 0.3 at rest, 1.6 at turning around in bed and 0.8 at standing (6.8 pre-operatively). Transient sensible or motoric deficits, due to the local anesthetics' effect, occurred in 8 respectively in 3 of the patients. Drug-induced typical side-effects were pruritus, nausea and emesis. No cardiopulmonary complications happened.
  
  
  CONCLUSIONS
  The epidural lumbal analgesia is an effective and safe method to control postoperative pain after spinal instrumentation surgery. Precondition is the knowledge about the safe and standardized technique of intraoperative catheter placement by the orthopedic surgeon, the choice of the appropriate analgesic drugs and a good cooperation between the departments of anesthesiology and orthopedic surgery and nursing staff.
