Evaluation of the disinfective efficacy of povidone-iodine with the use of the transparent film dressing OpSite Wound.

To determine the duration of efficacy of disinfection with povidone-iodine (PVP-I) conducted before application of OpSite Wound (Smith and Nephew, UK), bacteriological evaluation was carried out. In 9 healthy adults, 3 sites on the forearms or other parts were chosen for application of OpSite Wound after adequate disinfection with PVP-I. As compared to the bacterial count score of 1.67-2.00 before disinfection, a significant reduction of the score was observed on removal of OpSite Wound on days 1, 2 and 3. The score of 0.5-0.67 immediately after disinfection did not change or deteriorate until removal of OpSite Wound. This finding supports the fact that unnecessary dressing changes could be avoided postoperatively for at least 3 days by disinfection with PVP-I and application of OpSite Wound particularly for operations categorized as 'clean surgery'.

A silver sulphadiazine-impregnated lipidocolloid wound dressing to treat second-degree burns.

OBJECTIVE: To evaluate the efficacy and tolerance of Urgotul SSD dressing (Laboratoires Urgo) in the treatment of second-degree burns. METHOD: This was a national multicentre phase III non-comparative open-label prospective study involving 10 burns units. The 41 subjects were non-immunosuppressed adults with second-degree thermal burn(s), which were clinically non-infected, less than 24 hours old, had a surface area less than 500 cm2 and warranted the local use of silver sulphadiazine. For four weeks, subjects were followed up weekly with a clinical assessment, bacteriological swabs and photographic recording. RESULTS: Of the 41 patients, 24 healed within a mean of 10.8 days and 13 had a skin graft on the study burn within a mean of 11.5 days. There were four premature study withdrawals. The total number of cumulative treatment days was 445, and 298 treatments were performed (including 257 dressing changes). Mean dressing wear time was 1.73 days. None of the subjects acquired a secondary infection. Researchers took 121 bacteriological samples, and wound colonisation with Staphylococcus aureus was found in only one patient. At follow-up nursing staff reported that dressing acceptability was good. CONCLUSION: Use of Urgotul SSD led to a good wound outcome--wounds healed or were grafted.

[Allergic contact dermatitis to the Comfeel hydrocolloid dressing].

INTRODUCTION: Allergic contact dermatitis is frequent in patients with chronic leg ulcers. However, it rarely occurs with modern wound dressings and is exceptional with hydrocolloids. CASE REPORT: A 66-year-old woman was treated for a leg ulcer with the Comfeel plus(R) transparent hydrocolloid dressing for two months. She developed a pruriginous, erythematous and vesiculous dermatitis under the hydrocolloid plaques. Patch tests for the Comfeel plus(R) transparent hydrocolloid, the Comfeel plus(R) hydrocolloid, balsam of Peru and epoxy resin were positive. Only the positive test for the Comfeel plus(R) transparent hydrocolloid was clinically pertinent. The histological examination of the positive test was suggestive of eczema. DISCUSSION: To our knowledge, allergic contact dermatitis to Comfeel plus(R) hydrocolloid dressings has not been reported. Most previous studies which included systematic patch-testings in patients with leg ulcers showed high sensitization rates for various allergens, but no allergy to hydrocolloids. Only isolated cases of allergic contact dermatitis to another hydrocolloid (Duoderm E(R)) have been reported. Our case report shows that allergic contact dermatitis is a possible side-effect of Comfeel plus(R) hydrocolloid dressings. However, it seems exceptional. Since the patch-tests failed to identify the constituent responsible for this allergy in our observation, comprehensive allergologic investigations should be repeated in further cases.

Superiority of water application to water sealing in burn wound healing.

BACKGROUND: Recently there have appeared on the market many external dressings for wound management. They all use water-sealing materials to maintain wounds in a moist state. However, in our daily clinical observations, a water-sealing material sometimes results in poor wound healing. Although a water-sealing material does in fact keep the wound moist, the quality of the water is far from that of the optimum extracellular fluid. METHODS: A second-degree burn wound was made in the rat by contact with a metal stick. Experiment 1 was to evaluate the influence of delayed primary wound treatment on burn-wound depth progression. We used a time lag procedure. Each group was treated with a water-sealing application (hydrocolloid sheet). Experiment 2 was to investigate the progression-preventing effect of normal saline on a burn allowed to dry for 3 hours, we compared a group that received a water sealing (non-moistening and incomplete moisture) dressing with one that received a water-supplying (moistening) dressing with using chi-square test. RESULTS: In the Experiment 1 (time lag and water sealing test), the early group showed quite normal wound healing at 7 days after onset. The slough was thin (about 10-20% of full dermal thickness). The delayed groups showed the poor healing characteristic. The slough was relatively thick (about 30-60% of full dermal thickness). Three hours' delay seemed to bring about poor healing. In the Experiment 2 (water application test), the moistening (water application) group showed relatively good healing after seven days. The slough was as thin as in the early group in the Experiment 1. The non-moistening group showed a poor healing process like the delayed group in the Experiment 1. For the moistening group, the healing percentage of 77.8% was significantly greater than the 41.3% observed in the non-moistening group (chi-square test, p < 0.05). CONCLUSIONS: All the materials in wound dressing are water-sealing. When the component water under the sheet is far from the extracellular fluid, these applications bring about poor healing. Delayed application and incomplete moisture should be corrected by external water-application.

Calcium alginate dressings promote healing of split skin graft donor sites.

A prospective controlled trial was carried out to assess the healing efficacy of calcium alginate and paraffin gauze on split skin graft donor sites. Thirty patients were randomised to the calcium alginate group and 21 to the paraffin gauze group. The donor sites were assessed at 10 days post harvesting to determine if they were completely healed (100%) or not. Twenty one of the 30 patients dressed with calcium alginate were completely healed at day 10, while only 7/21 in the paraffin gauze group were healed (p < 0.05). There were two infections in the study, both occurring in the alginate group while there was no difference in dressing slippage between the two groups. Calcium alginate dressings provide a significant improvement in healing split skin graft donor sites.

Dressings and topical agents for surgical wounds healing by secondary intention.

BACKGROUND: Many different wound dressings and topical applications are used to cover surgical wounds healing by secondary intention. It is not known whether these dressings heal wounds at different rates. OBJECTIVES: To assess the effectiveness of dressings and topical agents on surgical wounds healing by secondary intention SEARCH STRATEGY: We sought relevant trials from the Cochrane Central Register of Controlled Trials, Cochrane Wounds Group Specialised Trials Register, MEDLINE, EMBASE, and CINAHL databases in March 2002. SELECTION CRITERIA: All randomised controlled trials (RCTs) evaluating the effectiveness of dressings and topical agents for surgical wounds healing by secondary intention. DATA COLLECTION AND ANALYSIS: Eligibility for inclusion was confirmed by two reviewers who independently judged the methodological quality of the trials according to the Dutch Cochrane Centre list of factors relating to internal and external validity. Two reviewers summarised data from eligible studies using a data extraction sheet, any disagreements were referred to a third reviewer. MAIN RESULTS: Fourteen reports of 13 RCTs on dressings or topical agents for postoperative wounds healing by secondary intention were identified. WOUND HEALING: Whilst a single small trial of aloe vera supplementation vs gauze suggests delayed healing with aloe vera, the results of this trial are un interpretable since there was a large differential loss to follow up. A plaster cast applied to an amputation stump accelerated wound healing compared with elastic compression, WMD -25.60 days, 95% CI -49.08 to -2.12 days (1 trial). There were no statistically significant differences in healing for other dressing comparisons (e.g. gauze, foam, alginate; 11 trials). PAIN: Gauze was associated with significantly more pain for patients than other dressings (4 trials). PATIENT SATISFACTION: Patients treated with gauze were less satisfied compared with those receiving alternative dressings (3 trials). COSTS: Gauze is inexpensive but its use is associated with the use of significantly more nursing time than foam (2 trials). LENGTH OF HOSPITAL STAY: Four trials showed no difference in length of hospital stay. One trial found shorter hospital stay in people after amputation when plaster casts were applied compared with elastic compression (WMD -30.10 days; 95% CI -49.82 to -10.38). REVIEWERS' CONCLUSIONS: We found only small, poor quality trials; the evidence is therefore insufficient to determine whether the choice of dressing or topical agent affects the healing of surgical wounds healing by secondary intention. Foam is best studied as an alternative for gauze and appears to be preferable as to pain reduction, patient satisfaction and nursing time.

Clinical experience with a new hydrogel wound dressing.

A new dressing is described which appears to improve wound healing after partial-thickness skin loss. The period between dressing changes is increased and patient discomfort decreased. It has been particularly useful in the treatment of scalds in children. There is no evidence of an increased infection rate. Alternative methods of sterilization may reduce the small number of minor hypersensitivity reactions.

Comparison of propolis skin cream to silver sulfadiazine: a naturopathic alternative to antibiotics in treatment of minor burns.

BACKGROUND: Propolis, a naturopathic substance derived from bees wax extract, has recently been praised for its antimicrobial, anti-inflammatory, and cicatrization-enhancing properties. OBJECTIVE: In our study, we compare these properties in a high-grade Brazilian propolis skin cream directly with silver sulfadiazene (SSD) in the treatment of minor burns (superficial second degree) in the ambulatory care setting (less than 20% total body surface area burned). SETTINGS/LOCATION: The study was conducted at the burn clinic in Pronto Socorro para Queimaduras, Gioania, Brazil. SUBJECT: Patients were admitted to the study only if their initial presentation for burn care was within 48 hours postinjury and if bilateral wounds of similar depth and quality were present. INTERVENTIONS: Patients had propolis skin cream applied to one wound and SSD applied to the other selected wound on initial presentation and underwent debridement and dressings change the following morning. Patients subsequently returned to the clinic every 3 days to have the wounds checked and dressings changed. At these check-ups, wounds were cultured for microbial growth and photographed to document inflammation and cicatrization. Patients were instructed not to disturb their wounds or change their dressings at home, thus propolis skin cream and SSD were applied to the wounds only at the specified 3-day intervals. RESULTS: Our preliminary results do not show any significant difference in microbial colonization between wounds treated with SSD and propolis skin cream, however, wounds treated with propolis skin cream consistently showed less inflammation and more rapid cicatrization then those treated with SSD. CONCLUSION: Propolis skin cream appears to have a beneficial effects on the healing of partial thickness burn wounds. If dressings had been changed more frequent the antimicrobial and wound healing effects would have been enhanced.

Cost-effective faster wound healing with a sustained silver-releasing foam dressing in delayed healing leg ulcers--a health-economic analysis.

The aim of this analysis was to examine the cost-effectiveness of Contreet Foam (A) in comparison with three other commonly used venous leg ulcer treatment protocols: Aquacel Ag (B), Actisorb Silver (C) and Iodoflex (D). A health-economic analysis reflecting the UK treatment practice and cost structure was performed. The analysis was set up to assess the cost of relative wound area reduction over a 4-week treatment period. The model was validated by a UK expert panel consisting of four wound care specialists. To assure that the 4-week model had a realistic link to cost-effectiveness of complete wound healing, a Markov analysis was also performed. Sensitivity analyses were carried out to ensure validity. Protocol A and C proved to be the most effective treatments. The mean relative reduction in wound area after 4 weeks of treatment was 50.2% (protocol A), 23.9% (protocol B), 44.6% (protocol C) and 36.0% (protocol D). Cost-effectiveness ratios showed that protocol A proved to be the most cost-effective treatment, and protocol B the least. The cost per percentage reduction in wound area was 9.50 UK pounds for protocol A, compared to 16.50-17.60 UK pounds for the other treatment options. The cost-effectiveness of complete healing (Markov analysis) and sensitivity analyses confirmed these results. Using Contreet Foam instead of the other dressing alternatives may imply savings of 2.2-4.4 million UK pounds per year to the National Health Service.

The Tielle family of dressings: overview of the product range.

The Tielle family (Johnson & Johnson Medical) is a range of dressings that come in a variety of shapes and sizes, designed to fit the different types and locations of wounds that occur in practice. There are three types--Tielle, Tielle Lite and Tielle Plus--and the choice of dressing should be based on the degree of exudate that the wound is producing. This product focus aims to give an overview of the range and provides research-based evidence for application in clinical practice.

Bilaminate synthetic dressing for partial thickness burns. Lack of cost reduction for inpatient care.

Forty-nine cases of second degree burns initially treated as inpatients from April 1984 through December 1987 are reviewed. Thirty-four patients were treated with bilaminate synthetic dressing (Biobrane) application, while 15 were treated with a topical antimicrobial, usually silver sulfadiazine. The burns ranged from 1 to 25 per cent total body surface area and were comparable in both groups. The mean age in each group was 30 years. Thirty patients were successfully treated with Biobrane, and their average hospital stay was 9.1 +/- 5.4 days compared with 9.2 +/- 8.6 days for the topically treated group. The mean hospital cost for dressings and supplies for the Biobrane group was $360 +/- $90 compared with $310 +/- $190 for the topical group. Four patients (12%) required Biobrane removal during their hospitalization, one due to increasing burn depth and three due to purulent fluid collections beneath the Biobrane. These burns were subsequently treated with topical antimicrobial agents and healed primarily. The mean total hospital stay for this group was 18.0 +/- 11.9 days with the costs being much higher secondary to the initial cost of the Biobrane, the costs associated with topical antibiotic therapy, and extended hospital stay. Although there was a decrease in nursing time and a subjective decrease in patient discomfort associated with using synthetic dressing, no benefit was found in either decreasing hospital stay or total cost of hospitalization and supplies used for inpatients treated at this institution.

A newly developed hydrofibre dressing, in the treatment of partial-thickness burns.

A newly developed, carboxymethylcellulose based hydrofibre dressing, Aquacel, was tested for the treatment of partial thickness burns. In this study 84 patients with mainly partial thickness burns were included, 76 patients received 1 or 2 days pre-treatment with a topical antimicrobial agent. Clinical behaviour showed a strong resemblance with cadaver skin treatment with respect to adherence to the wound. Adverse reactions, incidence of clinical wound infection, healing time and the need for wound excision and grafting were analysed, as was the final outcome using the 'Vancouver Scar Scale'. The mean size of the wounds treated with the hydrofibre dressing was 6.0% body surface area (min: 1%, max: 18%). Two patients clinically showed signs of a wound infection during treatment, but in general wound cultures were low or negative. In 42 patients (50%) the wounds healed completely within 10 days, in six patients (7%) small defects remained that healed by further treatment with a topical antimicrobial cream. In 36 patients (43%) excision and grafting of the remaining deeper parts of the wounds was performed as this is the standard therapy in the centre for all burned areas that have not healed within 2-3 weeks post-injury. The extent of the surgical procedures was limited since 66.1% of the wound area had healed already at the end of the hydrofibre treatment. In 54 patients the outcome of the treatment after 2-3 months was analysed by means of the Vancouver Scar Scale, which showed favourable results in general, and especially for patients who did not require surgery. Compared to earlier experience with allograft skin it was concluded that hydrofibre dressing is a safe, suitable and easy to use material for treatment of partial thickness burns.

Treatment of soft tissue defects with exposed bone in the head and face region with alginates and hydrocolloid dressings.

PURPOSE: In cases of soft tissue defects with exposed bone surfaces in the head and face region, there is the option of treating the defect with free split-thickness skin grafts following appropriate wound granulation. Secondary granulation on free bone surfaces is often a lengthy process, as granulation primarily occurs from the edges of the wound. Hydrocolloid dressings are gaining increasing attention in this context. The question arises as to whether the positive properties of hydrocolloid dressings can bring about rapid and positive conditioning of the base of the wound in soft tissue defects with exposed bone in the head and face region, with a view to subsequent split-thickness skin graft transplantation. MATERIALS AND METHODS: In the period from 1997 to 2000, a total of 25 patients with soft tissue defects with exposed bone surfaces in the head and face region were treated with hydrocolloid dressings in the framework of a prospective clinical study. RESULTS: The average time taken for complete granulation of the bone surface was 39.44 days (minimum, 10 days; maximum, 72 days). As a rule, this necessitated 12.8 changes of dressing (minimum, 3; maximum, 26). The granulation tissue was of good quality, generously vascularized, and occasionally exuberant at the edges of the wound CONCLUSION: On the whole, the combination of hydrocolloid dressing and alginate compress was found to have significant advantages as regards conditioning the exposed bone surface.

[Modified gloving technique for vacuum therapy in the hand].

INTRODUCTION: During the last 10 years sub-atmospheric pressure dressings (Topical Negative Pressure Therapy = TNP) has become a well accepted standard therapeutic modality in the management of acute and chronic wounds. However, in the hand and the fingers TNP treatment is not as an established method as elsewhere in the body. This is mostly due to difficulties in the technique of sealing wounds near the interdigital folds, especially when the interdigital folds are affected themselves. MATERIALS AND METHODS: Over a period of 36 months we treated 9 extensive open wounds of the hand with the TNP dressing procedure. To optimize the effective sealing procedure several methods of closure were applied: sterile vinyl gloves, split V.A.C. gel-straps and the "Sandwich"-principle. RESULTS: In all cases we were able to achieve a tight vacuum sealing with the use of our vinyl or latex free surgical glove as an aid to cover the interdigital spaces. There was a rapid and complete remission of the symptoms in terms of edema, redness, tenderness and range of motion. The indication spectrum encompassed infection control, temporary coverage of exposed bone or tendons, intermittent irrigation with local antiseptics as well as wound preconditioning before skin grafting or flap coverage. For the definite closure or coverage a second operation was necessary in all cases. CONCLUSIONS: The TNP-dressing can be securely achieved even in wounds encompassing the interdigital folds or adjacent to the in digital spaces with a modified surgical gloving technique to aid the standard sealing foil. It is a suitable principle for the management of severe hand infections with a reduction of clinical symptoms, reduction of the frequency of dressing changes compared to open approaches and a significant amelioration in the quality of life both for patients and health care personnel.

Clinical comparative study of aquacel and paraffin gauze dressing for split-skin donor site treatment.

The management of split-thickness skin graft donor sites is targeted towards promoting the healing process, while minimizing adverse effects and complications. The aim of this study was to compare donor site treatment outcome between Aquacel, a carboxymethylcellulose-based hydrofiber dressing, and the standard mesh paraffin gauze dressing. The study included 23 adult patients. Half of the skin graft donor site in the proximal thigh was dressed with paraffin gauze and the rest with Aquacel. The results indicated that patients treated with Aquacel experienced significantly less pain and a more rapid rate of epithelialization compared with patients treated with mesh paraffin gauze dressing. Final scarring (ie, after the 1-year follow-up) was significantly better with the Aquacel dressing. We conclude that Aquacel dressing is superior to the standard mesh paraffin gauze dressing for split-thickness donor site area in pain relief, ease of treatment, promotion of epithelialization, and the quality of scarring.

Ranking of the antipsoriatic effect of various topical corticosteroids applied under a hydrocolloid dressing--skin-thickness, blood-flow and colour measurements compared to clinical assessments.

In 10 patients with chronic plaque type psoriasis one or two plaques affected equally with psoriasis were chosen for study. Five punched out rings of a hydrocolloid dressing were applied to the psoriasis plaque(s). In each circular test area 20 mg of one of the following creams was applied: base, 1% hydrocortisone (DAK), 0.1% triamcinolone acetonide (Kenalogue), 0.1% betamethasone-17-valerate cream (Betnovate), and 0.05% clobetasol proprionate cream (Dermovate). The areas were occluded with a thin film of transparent hydrocolloid dressing (Comfeel Transparent Dressing), for 1 week. Non-invasive measurements (ultrasound skin thickness, laser-Doppler flowmetry, colorimetry) were performed before and after treatment. Therapeutic response was evaluated blindly by clinical score. The measurements showed a decline in blood flow, a decrease in skin thickness, and normalization of colour approaching that of normal skin, the more potent the corticosteroid used. The clinical scores showed the same: the more potent a corticosteroid used, the closer to the score of normal skin. Data on variability and applications of the methods are presented. The study concludes that potent corticosteroids occluded with a hydrocolloid dressing can clear psoriasis in 1 week. Short-course corticosteroid therapy appears harmless and relevant for clinical dermatology.
