Risk factors for necrosis of skin flap-like wounds after ED debridement and suture

The American Journal of Emergency Medicine Apr 28, 2019

Qiu D, et al. - Authors retrospectively examined 600 individuals with skin flap-like wounds between January 1, 2013, and December 31, 2016, to study the causes of flap necrosis. They recorded participants’ age, sex, injury reason, flap size, wound length-width ratio, pedicle thickness, operation time, injury site, direction of blood perfusion in the flap, and operating methods. A total of 22 flaps were salvaged by subcutaneous injection of anisodamine, selective suture removal, and a pressure dressing with elastic bandages among 67 flaps with vascular crisis. In terms of sex, age, and size of flap, they did not find significant difference between 45 patients with flap necrosis and those without necrosis. Significantly different incidence of flap necrosis was reported in terms of injury reason, length-width ratio of wound, thickness of pedicle, operation time, injury site, direction of blood perfusion in the flap, and operating methods.
