Repair of electrical burns on hands with flaps / 中华烧伤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the experiences and shortcomings of repair of wounds on hands due to electrical burns with flaps, aiming at further improvement.</p><p><b>METHODS</b>Clinical data of 425 patients with electrical burn of hands admitted to Burn Institute of Wuhan, City Hospital NO. 3 & Tongren Hospital of Wuhan University from January 2000 to December 2006 were collected and summarized. Therapeutic methods and outcomes of all patients were statistically analyzed. Flap types, complications after surgery and problems existed in patients having undergone flap transplantation were summarized. Patients were divided into surgery within 7days post burn (PBD) group (SW) and surgery after PBD 7 group (SA) according to the timing of surgery. Survival rate of flaps and incidence of complications in patients of two groups were compared.</p><p><b>RESULTS</b>Out of the 425 patients, 348 (90.2%) patients underwent surgery, among which 248 flaps of different types were transplanted in 209 patients, including 202 (81.5%) distant pedicle flaps, 19 (7.7%) local flaps, 12 (4.8%) free flaps, and 15 (6.0%) other kinds of tissue flaps. Five flaps failed because of necrosis of torn off, and the resulting wounds were treated with other methods. Eight flaps showed necrosis of distal margin, and the wound healed with dressing changing or skin grafting. All the remaining flaps survived with satisfactory cosmetic and functional results. In SW group (n = 170) and SA group (n = 78), survival rate of flaps was respectively 98.8% (168/170) and 96.2% (75/78), incidence of complications was respectively 10.6% (18/170) and 12.8% (10/78). There was no statistical difference between above two sets of data (with chi(2) value respectively 0.81 and 0.27, and P values both above 0.05).</p><p><b>CONCLUSIONS</b>There are many types of flaps that can be used to repair electric burn wounds on hands. Appropriate choice and design of flaps, skillful operation, and careful post-operation observation and treatment are key points for good therapeutic effect.</p>
