Modified negative-pressure wound therapy for linear blister formation prevention around foam dressings: technical note and case series
Abstract Background Linear blisters (LBs) often occur around dressings when negative-pressure wound therapy (NPWT) is used to cover open wounds. Tension blisters may increase the wound infection incidence rate, delay the start of operation, and prolong the duration of hospital stay. Currently, there...

| description | Abstract Background Linear blisters (LBs) often occur around dressings when negative-pressure wound therapy (NPWT) is used to cover open wounds. Tension blisters may increase the wound infection incidence rate, delay the start of operation, and prolong the duration of hospital stay. Currently, there are no established methods for the prevention of LB formation around dressings, which remains to be a major concern in clinical applications. Therefore, we developed a novel, simple, reproducible, and convenient method for preventing LB formation around NPWT dressings. Method Fifty-three cases of Gustilo type II and III open fractures under NPWT were considered. NPWT was used on every wound after debridement. All patients were divided into a conventional group (27 cases, 33 wounds) and a novel group (26 cases, 27 wounds) based on the difference in the NPWT dressing appearance. A healthy volunteer with intact skin was also included to perform the detailed process of NPWT. LBs occurring on intact skin around the dressings were observed and recorded when the dressing was removed 3 days after the operation. The occurrence of LB formation and wound infection was considered as categorical data and compared between the two groups using a chi-square test. The duration of hospital stay was considered as numerical data and compared between the two groups using two independent t tests. Results The percentage of occurrence of LB formation around dressings in the conventional group was 27.3%, whereas it was merely 3.7% in the novel group (P = 0.037). The infection incidence rate in the conventional group was 30.3%, whereas that in the novel group was 25.9%; however, no statistical difference was observed between the two groups (P = 0.708). The average duration of hospital stay in the conventional group was 14.39 ± 4.55 days, whereas that in the novel group was 11.04 ± 3.47 days (P = 0.003). Conclusion Thus, changing the NPWT dressing appearance can prevent LB formation around dressings, providing an effective method to improve NPWT application. Modified NPWT dressings also shorten the duration of hospital stay, but do not significantly decrease the incidence of wound infection. |
