Objective: To investigate the clinical effect of modified closed negative pressure suction technique combined with flap transplantation on the treatment of deep chronic refractory wounds. Methods: During March of 2015 to April of 2018, 52 cases of patients with deep chronic refractory wounds were selected as research objects. They were divided into the control group and the treatment group by use of the random number table method, with 26 cases in each group. Among them, the control group was given conventional debridement combined with flap reconstruction, and the treatment group was treated with modified closed negative pressure suction technique combined with flap transplantation to observe the clinical effect. Results: (1) According to the analysis on the effect of flap transplantation, the excellent and good rate of the treatment group was 92.3%, and in the control group, it was 76.9% ( p < .05). (2) According to the statistics, the incidence of complications in the treatment group was lower than that in the control group ( p < .05). Conclusions: Modified closed negative pressure suction technique combined with flap transplantation has a good effect on the treatment of deep chronic refractory wounds with fewer complications.
