ABSTRACT
Objective:
To investigate the effect of modified double negative-pressure wound therapy combined with debridement and tension-reduced suture in treatment of stage 4 pressure sores and infection in sacrococcygeal region and its surrounding area.Methods:
From January 2015 to June 2019, 20 patients with stage 4 pressure sores and infection in sacrococcygeal region and its surrounding area were admitted to Department of Burns and Plastic Surgery and Cosmetology of Linyi People's Hospital. Among them, there were 11 males and 9 females, aged 48 to 88 years. The wounds of 13 patients were located in the sacrococcygeal region, and 8 of them had exposed sacrococcyx. The wounds of 4 patients were located in the greater trochanter area of femur, and the wounds of 3 patients were located in the ischial tuberosity area. All the patients had fever in different degree, bacterial infection, hypoproteinemia, and electrolyte imbalance, etc. at admission. After thorough debridement and dressing change, routine negative-pressure wound therapy with negative pressure value of -16.6 kPa was performed according to the scope of lesions in period â . When granulation tissue was fresh with less exudate and without residual necrotic tissue, modified double negative-pressure wound therapy in combination with debridement and tension-reduced suture was performed immediately in period â ¡. Modified double negative-pressure wound therapy were persistently performed through negative pressure drainage tube inserted into deep part of wounds and negative pressure drainage tube on surface at the same time, with superficial negative pressure value of -19.9 kPa. Meanwhile, systemic anti-infection and nutritional supports were given. The wounds were monitored for the grade of wound healing and whether skin necrosis, split, or fluid accumulation develop at the suture site. The patients were followed up for 1 to 6 months after discharge to monitor wound healing. Length of hospital stay, infection condition before and after the debridement and tension-reduced suture, and complications during treatment were recorded.Results:
All wounds achieved first grade healing, with the skin at the suture site healed without split, fluid accumulation, or necrosis. The patients were followed up for 1 to 6 months after discharge, with good shape of surgical incision, little pigmentation on the skin, no hypertrophic scar or contracture, and no recurrence of pressure sores. Length of hospital stay of patients was 24 to 33 d, with an average of 28.5 d. Before debridement and tension-reduced suture, 2 cases were infected with Pseudomonas aeruginosa, 1 case was infected with Escherichia coli and Staphylococcus aureus, and 1 case was infected with Proteus mirabilis. The results of bacterial culture were all negative after debridement and tension-reduced suture. During the treatment, all patients were not complicated with bone or joint infection, necrotizing fasciitis, septicemia, etc.Conclusions:
Modified double negative-pressure wound therapy combined with debridement and tension-reduced suture for treatment of patients with stage 4 pressure sores and infection in sacrococcygeal region and its surrounding area is easy to operate with minimal injury, easy for patients to accept with a very high level of satisfaction, and is suitable to popularize and applicate for primary hospitals.Palabras clave
