Secondary wound dressings: an evaluation of Alldress.

Nurses are increasingly faced with the need to balance clinical efficacy with economic advantages when selecting wound management products. Compared to 20 or 30 years ago the money spent by the NHS in the UK on wound dressings has risen dramatically. It is also true that the rise in costs has, for the most part, been matched by an improvement in product performance. It is, however, important that claimed advances in wound management products are assessed critically to ensure they provide both clinical and economic benefits. In this article the authors explore the use of a secondary wound dressing. Using a case study methodology, the authors have conducted an evaluation aimed at identifying possible economic benefits associated with the study dressing as opposed to more expensive alternatives. In the case studies observed the dressing has been found to provide the required level of clinical performance at a considerable saving when compared to other modern wound management dressings. The authors conclude that these initial findings merit further investigation as they could, if replicated on a larger scale, result in considerable cost savings for the NHS without sacrificing clinical standards.

Hydrocapillary dressing to manage exudate in venous leg ulcers.

This study evaluated the safety and clinical performance of Alione hydrocapillary adhesive dressing, Coloplast A/S, a newly developed moist wound healing dressing designed for exudate management of heavily to lightly exuding ulcers. Twelve patients with heavily to moderately exuding chronic venous leg ulcers were assessed during a 4-week observation period. Assessments included healing progress, pain, odour, peri-ulcer skin condition, ease of use, patient comfort and suitability of the dressing for managing exudate. The median ulcer area was reduced by 71% (P<0.05) and the wound bed tissue improved markedly. No leakages of exudate were reported and the overall impression of the dressing was good. The amount of exudate assessed subjectively (P<0.05). Pain and odour were reduced effectively. No dressing-related adverse events were observed. This study has demonstrated that Alione is safe and easy to use, and exhibits convincing clinical performance and exudate-handling properties in the treatment of chronic venous leg ulcers.

The analgesic effect of odour and music upon dressing change.

Vascular wounds may require frequent dressing changes over a long period of time, often involving pain, which may not be adequately controlled with conventional analgesia. Complementary analgesia may be beneficial as an adjunctive therapy. This pilot study presented eight patients with two odour therapies, lavender and lemon, two music therapies, relaxing and preferred music and a control condition, during vascular wound dressing changes. Although the therapies did not reduce the pain intensity during the dressing change there was a significant reduction in pain intensity for the lavender therapy and a reduction in pain intensity for the relaxing music therapy after the dressing change. This supports the use of these complementary therapies, which are inexpensive, easy to administer and have no known side effects, as adjunctive analgesia in this patient population. Earlier administration before dressing change may enhance these effects. Further research is required to ascertain why certain complementary therapies are more effective than others at relieving pain.

A comparison of dressings in the management of surgical abdominal wounds.

This prospective randomised trial compared the performance of three dressing protocols in the management of 36 dehisced surgical abdominal wounds: a standard alginate; a gauze moistened with sodium hypochlorite (0.05%); and a combine dressing pad. Outcomes assessed were: healing time (cm2 per day and cm3 per day), patient comfort (pain and satisfaction) and cost. There were no statistically significant differences in healing rates between the three groups but there was a trend for the combine dressing pad protocol to produce a greater reduction in wound area. The combine dressing pad protocol performed well when compared with the calcium alginate in terms of healing time, patient comfort and cost. Maximum pain was significantly greater (p = 0.011) and satisfaction significantly lower among patients who received the sodium hypochlorite protocol. Costs during the in-patient phase were also substantially higher for the sodium hypochlorite protocol. Trial results support the view that sodium hypochlorite dressing protocols for surgical wounds should be abandoned.

Comparison of two dressings in the management of partial-thickness donor sites.

This study evaluated and compared the performance of an adhesive hydro-cellular dressing with that of a paraffin gauze dressing in the treatment of partial-thickness skin-graft donor site wounds. Fifty patients were included in the study, each acting as his/her own control. Donor site area ranged from 20 cm2 to 71 cm2; half the area of each patient's donor site was treated with the trial dressing, the other half with paraffin gauze. Outcome measures assessed were: time to complete epithelialisation; ease of dressing removal; pain on removal; and appearance of the wound bed. The trial dressing demonstrated a significantly faster healing time (p < 10(-6)) and enhanced patient comfort.

An in-vitro study of the pressure-relieving properties of four wound dressings for foot ulcers.

This in-vitro study reports on a selection of mechanical tests on four wound dressings: Allevyn (Smith and Nephew), Biatain (Coloplast), Lyofoam (Seton Scholl) and Tielle (Johnson and Johnson). The aim of the study was to investigate these dressings in the laboratory by subjecting them to dry and wet compression tests, shearing tests and a cyclical test. As predicted, all dressings performed differently in the range of tests, with Lyofoam deforming the most when subjected to compression testing (5.6 mm). During wet compression, differences in the physical properties of all the materials tested were identified. During shearing testin, Allevyn and Tielle withstood the greatest shear deflection before failure, but Biatain withstood the greatest force before failing. During the cyclical testing, Lyofoam only reduced by 1% of its original thickness, while Biatain reduced by 30%. No one dressing performed better in all the tests. However, as an all-round 'pressure-relieving' dressing, Allevyn consistently outperformed the others in the study.

A comparison of the antimicrobial effects of four silver-containing dressings on three organisms.

OBJECTIVE: To compare the antimicrobial activity of four silver-containing dressings: Acticoat (Smith and Nephew), Actisorb Silver 220 (Johnson and Johnson), Avance (SSL International) and Contreet-H (Coloplast). METHOD: The dressings were tested against three micro-organisms: a Gram-positive bacterium, Staphylococcus aureus; a Gram-negative organism, Escherichia coli; and a yeast, Candida albicans, using three different techniques. Each dressing also had its silver content analysed. RESULTS: Acticoat is likely to produce the most rapid antimicrobial effect in vitro because of the rapid release of relatively large concentrations of highly active silver ions. Contreet-H has broadly similar antimicrobial activity to Acticoat, but has a slower onset of action. Actisorb Silver 220 appears to offer less prospect of killing bacteria within the wound itself, but the dressing is capable of removing micro-organisms from wound exudate and sequestering them until they are inactivated by the silver within the charcoal fibres. Little convincing evidence for any antimicrobial activity of Avance was found. CONCLUSION: Although caution must always be exercised when extrapolating the results of laboratory-based studies to the clinical situation, potentially important differences were detected in the antimicrobial activity of the four products examined. It is also possible that the silver ions released by the dressings may have effects on wound healing that are unrelated to their antimicrobial activity. Further work is needed to address this issue.

A randomised controlled trial comparing Drawtex with standard dressings for exuding wounds.

OBJECTIVE: This randomised controlled clinical trial compared a capillary dressing (Drawtex, now rebranded as Vibriant RCD [Vibriant Technology Services]) with routine practice for exuding wounds greater than 2.5 x 2.5 cm. METHOD: The target population was 300 control and 300 test subjects across three sites in the UK, but recruitment difficulties resulted in only 125 patients being evaluable. Wound progress was recorded by nurses' perception of the progress of wound healing and by objective digital imaging. In the final analysis digital images were randomised (in time order) and a panel of nurses who were not otherwise involved in the research project graded the wound's progress. RESULTS: After deconvolution of the data, the subjective (nurse perception) method of evaluation determined that the new dressing resulted in wound improvement in 12.7% more patients than did routine practice, but the blinded assessment method (based on the digital images) showed that routine practice was better by 6.6%. CONCLUSION: Evaluation of wound progress is clearly difficult. Human nature makes us favour novelty if we believe it is going to be better. Making interpretation more objective removed that bias and did not demonstrate a significant advantage for the test dressing. The findings suggest that unblinded assessment by trial nurses is unacceptable on its own. Blinded assessments may miss finer nuances of wound progression, but are likely to be more accurate. The authors suggest that the true result lies somewhere in the middle, with the trial dressing likely to be as effective as, but not more effective than, a standard dressing.

An in vitro study of antimicrobial activity and efficacy of iodine-generating hydrogel dressings.

OBJECTIVE: To determine the antimicrobial activity and efficacy of different formulations of novel bioxygenating hydrogel dressings (which deliver both iodine and oxygen into the wound) against various target organisms by means of an in vitro test system that more effectively mimics the conditions encountered when dressings are in contact with wounds. METHOD: Three bioxygenating hydrogels were tested: Oxyzyme, which releases low levels of iodine into the wound, and Iodozyme 402 and Iodozyme 401, which release higher levels of iodine, with Iodozyme 402 releasing twice the amount of 401. Cellulose filter disks (n = 32) were inoculated with indicator species and placed equidistant from each other as a matrix onto agar test beds. Cut squares of control or test dressings were placed on top of each disk. Kill curves were constructed from determinations of the numbers of survivors (log cfu per disk) over time by removing disk samples at various time points. RESULTS: Significant differences (p < 0.05) were observed between the controls and test samples. The order of sensitivity for Oxyzyme was Fusobacterium nucleatum, Bacteroides fragilis, Propionibacterium acnes, Staphylococcus epidermidis, methicillin-resistant Staphylococcus aureus (MRSA), Candida albicans and Pseudomonas aeruginosa. The order of efficacy of the three hydrogel dressings (Iodozyme 402, followed by Iodozyme 401 and then Oxyzyme) was the same regardless of the target species. CONCLUSION: The novel hydrogel skin surface wound dressings are broad-spectrum in activity, encompassing antibiotic-resistant organisms, anaerobes and yeasts; their antimicrobial function appears to be rapidly effective.

[Microbiological evaluation of 1% silver sulfadiazine dressings].

This study aimed at evaluating the microbial condition and antimicrobial activity of 1% silver sulfadiazine dressings used in burns, prepared in advance of the dressing change and stored for 12 to 60 hours before usage. The microbial condition was evaluated by means of three cultures prepared from the Letheen Broth (Difco) culture medium and incubated at 32-35 degrees C for 20 days. Antimicrobial activity was evaluated by means of the diffusion technique of one dressing culture in hospital strains, initially incubated at room temperature and then at 37 degrees C, for 18-24 hours. All three cultures of 12, 36 and 60 hours proved negative. Concerning antimicrobial activity, the zones of inhibition were: 2.25 mm for S. aureus; 2.65 mm for P. aeruginosa and 2.95 mm for E. coli. These dressings can be safely prepared by nurses and stored, reducing nurses' time spent for dressing change and, consequently, patients' exposure.

Influence of light intensities on dressing behavior in elderly people.

With civilized environments in modern society, since the people tend to depend more on artificial illumination than on natural illumination which makes less discrepancy between day and night life, clarifying the relationship between human life and illumination is necessary. In our previous studies, we found that the subjects dressed faster with thicker clothing in the morning than in the evening when the room temperature decreased from 30 degrees C to 15 degrees C over 1 hour. We considered these results in terms of load error between the actual and set-point values in the core temperature. The present study was designed to examine the effect of bright light (3,000 lx)/dim light (50 lx) exposure (09:30 h-14:30 h) on dressing behavior and thermoregulatory responses in the elderly people during the afternoon cold exposure. Five female subjects were instructed to dress to feel comfortable when the room temperature was decreased from 30 degrees C to 15 degrees C (15:00 h-17:00 h). The subjects felt cooler and dressed more quickly with thicker clothing after dim light exposure, it is conceivable that the set-point value of core temperature is reduced under the bright light condition. We discussed these results in terms of the establishment of set-point values in the core temperature at bright light condition. If the set-point of the core temperature is lower in the bright than in the dim light condition in present experiment, the dressing behavior with thinner clothing in the bright light condition is advantageous, since it enables the core temperature to reach its set-point value more easily.

Wound care: fact and fiction about hydrocolloid dressings.

1. Hydrocolloid dressings have two layers. The inner, hydrocolloid adhesive layer has particles that absorb exudate to form a hydrated gel over the wound, creating a moist environment that promotes healing and protects new tissue. The outer layer (film, foam, or both) forms a seal to protect the wound from bacterial contamination, foreign debris, urine, and feces; it also maintains a moist environment and helps prevent shearing. 2. Hydrocolloid dressings are designed to be worn for up to a week. Infrequent dressing changes are less disruptive to the wound bed, provided that healthy skin is not compromised. Many patients--and even some medical professionals--still incorrectly believe that wounds need to be exposed to the air to heal properly. 3. Hydrocolloids are not always the dressing of choice in wounds that have limited drainage or in wounds with copious amounts of drainage. The hydrocolloid dressing is designed to manage drainage; if drainage is minimal, another approach may be more economical and comfortable for the patient.

Microbiological safety of mayonnaise, salad dressings, and sauces produced in the United States: a review.

The literature on the death and survival of foodborne pathogens in commercial mayonnaise, dressing, and sauces was reviewed and statistically analyzed with emphasis on Salmonella, Escherichia coli O157:H7, and Listeria monocytogenes. The absence of reports of foodborne illness associated directly with the consumption of commercially prepared acidic dressings and sauces is evidence of their safety. Salmonella, E. coli O157:H7, E. coli, L. monocytogenes, Staphylococcus aureus, and Yersinia enterocolitica die when inoculated into mayonnaise and dressings. Historically, mayonnaise and dressings have been exempt from the acidified food regulations and have justly deserved this status due primarily to the toxic effect of acetic and to a lesser extent lactic and citric acids. These organic acids are inimical to pathogenic bacteria and are effective natural preservatives with acetic being the most effective in killing pathogenic bacteria at the pH values encountered in these products. Statistical analysis on data reported in the literature shows that the most important and significant factor in destroying pathogenic bacteria is pH as adjusted with acetic acid followed by the concentration of acetic acid in the water phase. The reported highest manufacturing target pH for dressings and sauces is 4.4, which is below the 4.75 pKa of acetic acid and below the reported inhibitory pH of 4.5 for foodborne pathogens in the presence of acetic acid. The overall conclusion is that these products are very safe. They should remain exempt from the acidified food regulations providing adequate research has been done to validate their safety, and the predominant acid is acetic and reasonable manufacturing precautions are taken.

Relationship of constructional apraxia and body scheme disorders in dressing performance in adult CVA.

The relationship between constructional apraxia and body scheme disorders and failure of post-cerebral vascular accident (CVA) patients to achieve independence in upper extremity dressing was investigatged in this study. One hundred and one subjects with right- and left-CVA were given tests that measured body scheme dysfunction and constructional apraxia on admission to an inpatient rehabilitation unit, and then rated on upper extremity dressing performance at discharge. Scores on the apraxia and body scheme tests were statistically correlated with dressing performance. The results indicated that both constructional apraxia and body scheme dysfunction contribute to failure in achieving upper exremity dressing, but that body scheme performance is a better predictor of dressing ability. In addition, the presence of visual field deficits, medical complications, and aphasia were found to exert significant influence on subject performance.

Relationship between constructional praxis and dressing in the head-injured adult.

The purpose of this study was to explore the potential relationship between dressing ability and constructional praxis performance in a head-injured population. Thirty-seven patients with severe head injuries were rated on dressing ability and constructional praxis tasks in a rehabilitation setting. Three constructional praxis measures were taken: graphic, two-dimensional, and three-dimesional abilities. A significant relationship was found between mean dressing ability scores and all three constructional praxis scores. These findigs suggest that a portion of inability to dress is perceptual not motor, in origin in individuals with severe head-injuries, and that constructional praxis re-training has functional significance for the patient. No relationship was found between presencce or absence of Computerized Axial Tomography (CAT scan) abnormality and dressing or constructional praxis disability.

Alternative wound dressings in A&E.

Paraffin tulle dressings remain in common use in almost every accident and emergency (A&E) department. Dressing a wound with paraffin tulle necessitates the use of a secondary dressing which, in common practice, is almost always an absorbent pad or gauze. Such combined dressings may represent poor practice, because alternatives are now available which better satisfy the required characteristics of the optimum dressing (1). The author looks at some of the available alternatives.

Central line exit sites: which dressing?

Recent developments in dressings for intravenous access sites include a transparent dressing which does not retain moisture. This article describes a randomised controlled trial to compare the new dressing with a standard dressing. There was no difference in sepsis rates between the two groups, and both methods had advantages and disadvantages. The authors suggest that cost may be a factor in choice of dressing.

Pain and tissue trauma during dressing change.

BACKGROUND: Preventing patient pain and tissue trauma to the wound and surrounding skin are key considerations for nurses at the time of dressing changes. Mark Collier and Helen Hollinworth present the preliminary findings from a recent survey among nurses with an interest in wound care on the selection of dressing types. CONCLUSION: Education of student and post-registration nurses about the properties of dressing products, with an understanding of the potential detrimental effects as a result of pain and trauma, is needed to help promote quality wound care. Selecting appropriate dressings was reported as the main strategy nurses adopted to help prevent pain and trauma at the time of dressing change. Appropriate product selection can improve patients' quality of life and optimise wound healing potential.
