AbstractWound infusion with local anesthetics is a nearly 100 years old proven and secure analgesic method. Recently special wound infusion catheters have become available which can be placed intraoperatively into the wound under direct supervision of the surgeon to infuse local anesthetics and optimize postoperative analgesia. For thoracotomy this method was modified to improve its efficacy and the catheters are used to establish a continuous paravertebral intercostal nerve block (PVB). Many studies have confirmed the analgesic power of PVB which results in a pain reduction comparable to thoracic epidural analgesia (TEA) but without TEA-specific side-effects, in particular hypotension. The efficacy of continuous local wound infusion (CLWI) is less obvious for laparotomy. If fundamental preconditions for this loco-regional method are considered (indications, choice of catheter, local anesthetic dose) the laparotomy wound could also be suitable for the use of CLWI. According to the literature currently available CLWI is not associated with an increased risk of wound infections.
