Continuous Local Analgesia in Postoperative Treatment of Large Incisional Hernias – Preliminary Results

Background: The incisional hernias are frequent complications after laparotomy. Extended subcutaneous tissue dissection is often necessary for the treatment of large incisional hernias, and this procedure is frequently followed by a high intensity pain in the postoperative period. The aim of this study was to assess the postoperative patient comfort without using major analgesics.

Material and method: we present the preliminary results of an ongoing study from Surgery Clinic 1 of Emergency Clinical County Hospital of Târgu Mures, University of Medicine and Pharmacy Târgu Mures. The study comprises in the intraoperative insertion of a subcutaneous catheter (Pajunk InfiltraLong) placed on lay, through which we administered continuously Ropivacaine 0,5%.

Results: Ten patients have been included in the study by now. For 5 of the patients the wound infiltration was started with 7 ml/h in the first 6 postoperative hours, after which the rate decreased to 5 ml/h until the end of the 72 hours, when the catheter was removed. For 2 patients the wound infiltration was started with 10ml/h in the first 6 postoperative hours, after which the rate decreased to 7 ml/h in the first day, followed by 5 ml/h for the next two days. Two patients needed a minor analgesic in the immediate postoperative period and one patient needed major analgesia in the first 24 hours.

Conclusions: By using this method, postoperative analgesia can be achieved without using major systemic analgesics and a superior patient comfort can be achieved simply by adjusting the infusion rate
