Objective:To observe the clinical effect of closed negative pressure drainage on refractory wounds.
Methods:Seventy-eight patients with refractory wound were randomly divided into 2 groups; The treatment group (38 patients) was treated with closed negative pressure drainage ;the control group (40 patients) was treated by conventioal methods.The time for wound surface to enter into the red stage, the 1-week wound healing rate, and the overall healing time between the 2 groups were compared.
Results:Treatment group was significantly better than control group in the time for wound surface to enter into the red stage, the 1-week wound healing rate,and the overall healing time (all, P＜0.05).
Conclusions: The closed negative pressure drainage therapy is better than conventional treatment for refractory wound because it can promote wound healing and its use is convenient, and thus it is advocated for widespread use.
