Selection of dressing materials in chronic wound management

Chronic wounds are generally defined as non-healing wounds after four weeks of normal treatment. Individual risk factors for chronic wounds should be identified, but the delay of wound healing is often caused by the use of inappropriate dressing material. The concept of rapid wound healing with moist dressings has developed since the 1960s, and wet dressing is currently a widely popular method of wound treatment. Hundreds of dressing materials that maintain a moist environment are commercially available; however, selecting the right dressing material for a specific purpose is not easy, and unfortunately incorrect dressing procedures occur frequently. In order to promote wound healing education, we have classified dressing materials into basic categories and discuss the pros and cons and indications for each category. The purpose of this report is to reduce errors in selecting dressing materials and to enhance precise wound treatment.

Uso de espumas em áreas doadoras de enxertos / Use of polyurethane foam dressings on skin graft donor sites

Introdução: O sucesso de um enxerto de pele é avaliado não apenas pela integração do enxerto em si, mas também pela qualidade da recuperação da área doadora. A despeito de as áreas doadoras de enxertos representarem o melhor local para estudo de cicatrização de feridas, regimes de tratamento, de áreas doadoras, tem sido incompletamente estudados. Objetivo: Avaliação da eficácia de espumas de poliuretano como curativo de áreas doadoras de enxertos. Método: Estudo prospectivo no qual áreas doadoras de enxertos foram tratadas com espumas de poliuretano como alternativa a filmes de acetato de celulose. Resultados: Foram tratados 11 pacientes e catorze áreas doadoras de enxerto. Aderência prolongada (73%) e odor desagradável (45%) foram os problemas encontrados. Os resultados foram considerados insatisfatórios na grande maioria dos casos (73%). Conclusões: O uso de espumas de poliuretano mostrou-se ineficaz, nesse grupo de pacientes, devido à ocorrência de alto índice de complicações.

Introduction: The success of a skin graft is evaluated by not only the integration of the graft itself, but also the quality of the recovery of the donor site. Despite the fact that graft donor sites represent the best place to study wound healing, treatment regimens for donor sites have not been studied extensively. Method: To evaluate the efficiency of polyurethane foam as a dressing for graft donor sites. Methods: We conducted a prospective study in which graft donor sites were treated with polyurethane foam dressing, as an alternative to a cellulose acetate film. Results: We treated 11 patients and 14 donor graft sites. Problems associated with the use of polyurethane foam included prolonged adherence (73%) and an unpleasant odor (45%). The majority of patients reported that they found the dressing to be unsatisfactory (73%). Conclusions: The use of a polyurethane foam was shown to be ineffective as a graft donor site dressing, due to the high rate of associated complications.

Diabetic foot resulting in amputation: our experience.

Background: The aim of our study was to early diagnosis of diabetic foot so that the complications can be prevented, to control the systemic infection and prevent the complications, to study the effectiveness of regular dressing in diabetic foot so as to prevent the local spread of infection and the ulcer and to conclude that early diagnosis, care and proper meticulous treatment of diabetic foot can prevent amputation. Methods: The present study was prospective, observational and longitudinal. Protocol of the procedure was formed along with Performa, Patient Information Sheet, Informed Consent Form and approval from Ethical Committee. The present study was carried out in surgery department of C.U Shah medical college, Surendranagar; Gujarat state. The study was carried out from 1st August 2011 to 30th September 2013. A total of one hundred patients admitted in surgery ward with diabetes type 1 or 2 with ulcer on foot having grade 1 or 2 of Wagner’s classification without any other co morbid condition. These patients undergo daily dressing with various dressing solutions according to their ulcer characteristics. All the patients given diet/oral hypoglycaemic drug/insulin for control of diabetes. Antibiotics given according to the infective status of the patients. Patients were either completely treated, went under skin grafting or ended up with amputation were recorded. Results: Of 100 cases studied, youngest patient was 32 years and oldest was 80 years of age. Highest number of cases was found in the age group 61-70 years (30%). Of the 100 cases studied in this series 36 (36%) patient were having Wagner’s class 1 ulcer and 64 (64%) patient having class 2 ulcers. Of 100 cases, various surgical treatment given to the patients according to the ulcer. In that 65(65%) debridement, 20 (20%) Incision & drainage, 10 (10%) STG, 5 (5%) fasciotomy. Most of the patients were undergone basic surgical procedure which is debridement on the 7th day follow up, out of 100 cases 70 patients came for follow up. Out of 70, all patients having healing ulcer. Out of 70 patients, 15(21.43%) patients were underwent STG on 15th day and other 55 (71.57%) patients having healing ulcer advised daily dressing with follow up after 1 week. Out of 30 patients, 3 (10%) patients underwent amputation on 7th day of follow up. On the 15th day new 5 (16.67%) patients underwent amputations, so total number of amputation done till date was 8 (26.67%). On 21st day, new 7 (23.34%) patients were underwent amputations and total number of amputations till date were 15 (50%). On 30th day, new 15 (50%) patients underwent amputations. Conclusions: Foot ulceration in diabetic patients is a resource consuming, disabling morbidity that often is the first step towards lower extremity amputation. Prevention is the best treatment.

Comparison of Inofoam(R) and Medifoam(R) for Donor Site Dressing after Split Thickness Skin Graft in Burn Patients

PURPOSE: Inofoam(R) is a hydrocellular material developed recently for wound dressing. In the present study, the efficacy of Inofoam(R) for donor site dressing after split thickness skin graft (STSG) was evaluated and compared with that of Medifoam(R). METHODS: The study was conducted on 15 patients with third degree of burn underwent STSG from Nov. 2011 to Feb. 2012. Donor sites were divided into groups of Inofoam(R) and Medifoam(R). The duration of wound healing, pain score and exudate absorption ratio were compared between the two groups. RESULTS: The duration of wound healing time was 10.7+/-2.2 days in Inofoam(R) group, 10.5+/-2.0 days in Medifoam(R) group (P>0.05). On postoperative 1 day, the exudate absorption ratio in was 341.6+/-59.3% in Inofoam(R) group and 349.0+/-41.8% in Medifoam(R) group. There were no significant differences in wound healing duration, swelling ratio, and pain score between the two groups (P>0.05). CONCLUSION: The present study shows that the efficacy of a recently used polyurethane foam Inofoam(R) for donor site dressing is as effective as that of Medifoam(R).

Application of Modified Vacuum Assisted Closure with Silver Materials in Chronic Infected Wound

PURPOSE: Chronic infected wounds sustained over 4 weeks with exposed tendon or bone are difficult challenges to plastic surgeons. Vacuum assisted closure (VAC) device has been well used for the management of chronic wounds diminishing wound edema, reducing bacterial colonization, promoting formation of granulation tissue and local blood flow by negative pressure to wounds. But Commercial ready-made VAC device might have some difficulties to use because of its high expenses and heavy weight. So we modified traditional VAC device with silver dressing materials as topical therapeutic agents for control of superimposed bacterial wound infection such as MRSA, MRSE and peudomonas. METHODS: We designed the modified VAC device using wall suction, 400 cc Hemovac and combined slow release silver dressing materials. We compared 5 consecutive patients' data treated by commercial ready-made VAC device(Group A) with 11 consecutive patients' data treated by modified VAC device combined with silver dressing materials(group B) from September 2004 to June 2007. Granulation tissue growth, wound discharge, wound culture and wound dressing expenses were compared between the two groups. RESULTS: In comparison of results, no statistical differences were identified in reducing rate of wound size between group A and B. Wound discharge was significantly decreased in both groups. Modified VAC device with silver dressing materials showed advantages of convenience, cost effectiveness and bacterial reversion. CONCLUSION: In combination of modified VAC device and silver dressing materials, our results demonstrated the usefulness of managing chronic open wounds superimposed bacterial infection, cost effectiveness compared with traditional VAC device and improvement of patient mobility.
