title: Comparative study of abdominal incision techniques.
abstract: The characteristics of surgical incisions made with an electrosurgical technique were compared with those made using conventional methods in a prospective randomized trial. In particular, the claim that the method of incision may influence postoperative pain was investigated. A total of 101 consecutive patients receiving full-length midline laparotomy incisions for gastrointestinal resection were studied. A record was kept of the time required to make the incision and blood loss as well as postoperative pain (using a linear analogue scale), ventilatory function and requirement for analgesia. There were 50 patients in group 1 (scalpel; 15 men, 35 women) and 51 in group 2 (electrocautery; 26 men, 25 women). The groups were similar in age, body-weight, diagnosis and the type of surgical procedures being performed. Incision time was similar in the two groups but median blood loss during incision was significantly less in group 2 patients than in group 1 (10 versus 25 ml, P < 0.0001). Linear analogue pain scores were not significantly different between the groups at any stage after operation. The same was true of postoperative ventilatory function and requirement for analgesia. A total value for morphine use during the entire postoperative period was derived for each group and the median was 1.55 mg/kg for group 1 compared with 1.49 mg/kg for group 2. The electrosurgical method is associated with less blood loss during incision, although this study has failed to confirm any reduction in postoperative pain or requirement for analgesia in these patients.
