Abstract:
BACKGROUND: How to determine the proximal section of electricity-injury nerve which is available for nerve grafting, is key point to the functional recovery. The method used before is to observe if there is normal axonal structure under operating microscope. But the clinical result proves unsatisfactory.OBJECTIVE: To evaluate the appliance value of somatosensory evoked potential (SEP) technique in the detection of nerve injury after electrical injury.DESIGN: Retrospective analysis based on the cases.SETTING: Department of Plastic Surgery, Ninth People's Hospital Affiliated to Shanghai Jiaotong University PARTICIPANTS: Totally 12 patients with severe electrical injury who received treatment in the Department of Plastic Surgery, Shanghai Ninth People's Hospital were included in this study. Among them, there were 9male and 3 female, aged from 6 to 54 years.METHODS: SEP of injured nerve was measured progressively and pathological section observation was given correspondingly. The function recovery of patients receiving nerve transplantation by using SEP was evaluated and compared with that before treatment through a follow-up.MAIN OUTCOME MEASURES: Amplitude, latency and corresponding pathological section of SEP of injured nerve as well as the functional recovery of the SEP plane of the cases with patients receiving nerve transplantation by using SEP to choose transplanted plane.plitude and latency of SEP was positively correlative with the quality of were repaired with SEP technique to select the anastomosis site for nerve transplantation and 8 cases were followed up after operation. The average follow-up time was 22.7 months ranging from 17 to 26 months. And 2-point resolution sense reaches grade Ⅱ or Ⅲ in 5 cases. (America hand surgery association criterion: 2-point resolution distance ＜ 6 mm was grade Ⅰ ,6-10 mm was grade Ⅱ ,11-15 mm was grade Ⅲ ,＞ 15 mm was grade Ⅳ).CONCLUSION: Electricity-injured nerve owns complicated pathology.SEP technique is a valuable method for function evaluating or selecting of the anastomsis site for nerve grafting in those cases.
