Comparison between Negative Pressure Wound Treatment and Traditional Dressing Treatment for Open Fractures of Lower Limb Trauma
Objective To compare the effects of negative pressure wound therapy(NPWT)and traditional dressings on the treatment of open fractures of lower limb trauma.Methods From January 2021 to September 2023,120 patients with open fractures of lower limb trauma were selected and divided into a control group(60 cases treated with traditional dressings)and a study group(60 cases treated with NPWT)using a random number table method.The treat-ment effects,wound severity,pain,and inflammatory reactions of the two groups were com-pared.Result The rate of wound volume reduction and wound healing in the NPWT group was higher than that in the control group(P<0.05),and the rate of wound infection and wound healing time were lower than that in the control group(P<0.05).After 1 d and 7 d of treatment,the levels of pressure ulcer healing(PUSH)scores,VAS scores,hs-CRP,and WBC were low-er than those before treatment in both groups(P<0.05),and PUSH scores,VAS scores,hs-CRP,and WBC were lower than those in the control group in the study group(P<0.05).Conclu-sion Compared with traditional dressings for open fractures in lower extremity trauma,NPWT reduces the infection rate of the wound,promotes wound reduction and healing,reduces wound severity and pain,and inflammatory response.
