[Transparent adhesive tape as postoperative dressing. Randomized, clinical study for comparison with a conventional dressing technic].

To evaluate the effect of a thin, transparent, adhesive and elastic polyurethane drape permeable only to gas and water vapor molecules but not to bacteria in comparison to a conventional drape for postoperative dressings, a randomized trial was conducted in 90 male and female patients. 44 patients had the transparent adhesive drape and 46 a conventional dressing. Both groups were reasonably well matched according to age, sex, height, weight and type of operation. There was no difference in healing of skin wounds. But reddening around the stitches was seen more often in patients with the conventional dressing than in those with the polyurethane drape (p less than 0.05). Surprisingly, most of the patients with the transparent drape (42 of 44) accepted it. The transparent adhesive drape was found to be much less expensive than the conventional dressing.

Design of a new hydrocolloid dressing.

Hydrocolloid dressings composed of dextran, phospholipid, glycerol and sodium lauryl sulphate have been formulated. A ventilated hygrometer system has been used to study the evaporative water loss (EWL) from the excised wound of rats with and without these dressings. A statistical experimental design has been used to locate a formulation which is flexible and semiocclusive in nature. The phospholipid component of the dressing has a significant role in controlling water vapour permeability of the dressing. The EWL from the excised wound covered with the optimized dressing has been compared with that for two commercial products.

Wound blisters post hip surgery: a prospective trial comparing dressings.

INTRODUCTION: Wound blisters are formed in the epidermis adjacent to surgical incisions and are a significant cause of morbidity following hip surgery. This study was designed to compare two commonly used primary dressings, namely a nonadherent absorbable (NAA) dressing and paraffin tulle gras (PTG). Monitoring for the subsequent development of wound blisters in the epidermis adjacent to the surgical incision was then undertaken. METHODS: The present study was performed in the setting of a prospective, randomised trial of 50 consecutive patients undergoing hip surgery. It was assumed there would be no difference in the development of blisters between the dressing groups. The alternative hypothesis was that PTG would, because of its properties, provide less friction in the epidermis and contribute to fewer wound blisters. RESULTS: A statistically significant difference (P = 0.0028) between the two dressing groups was observed with the NAA group developing blisters in 17 (64%) patients and the PTG group in only two (8%) of the patients. CONCLUSION: The present study would suggest that PTG produces fewer wound blisters following hip surgery when compared to the NAA type as a primary dressing.

Normal saline wound dressing--is it really normal?

Gauze swabs soaked in normal saline are frequently used as dressing on open wounds. Their exact mechanism of action is not known. This study was designed to assess the hypothesis that normal saline dressings act in part as an osmotic dressing. Ten patients had skin ulcers (n = 10) dressed with normal saline soaked sponges. Acting as controls (n = 10) identical sponges were placed upon intact skin. The sponge fluid osmolarity and electrolyte concentrations were serially assayed to test our hypothesis. In the control group, the osmolarity, sodium and chloride concentrations increased with time as a result of evaporation, altering it from an isotonic to a hypertonic dressing. However, in the ulcer group, the osmolarity, sodium and chloride concentrations in the sponge fluid remained relatively isotonic with time. This result is statistically significant (P< 0.05). We postulate that, as a result of evaporation, the sponge dressing increases its tonicity. This draws fluid from the wound into the dressing so that a dynamic equilibrium occurs and the sponge dressing regains isotonicity. The dressing remains functional provided that the wound fluid is absorbed freely from the wound. This process is terminated when either the dressing completely absorbs the wound fluid or the dressing dries out. The latter often occurs prematurely in a contaminated wound or in a wound where exudate forms a non-permeable barrier which prevents osmosis and allows the remaining water in the dressing to evaporate completely. This correlates with the observation in clinical practice that for maximum efficacy the dressing should be changed regularly.

Wound care products: how to choose.

Working in PPS means that agencies and clinicians must determine which wound care regimen will reach the intended patient goal in the most cost-effective way in terms of supply and visit cost. This article outlines the specific rationale clinicians can use when assessing wounds and choosing the dressing(s) that are appropriate to meet patient and agency goals. Using the performance-based model approach, clinicians learn how to choose dressings based on product price versus treatment costs.

Evaluation study of the properties of two adhesive foam dressings.

The primary objective of this study was to assess the skin stripping of wounds (defined as periwound skin blistering; Fowler, 1990) when treated with an adhesive hydrocellular foam dressing (Allevyn trade mark Adhesive, Smith and Nephew) and a self-adherent soft silicone foam dressing (Mepilex trade mark Border, MöInlycke Health Care). The secondary objectives were to assess wound healing, wound appearance and pain. Data were collected over one year from 403 wounds in 206 patients treated in nursing homes. At follow-up assessment, there was some evidence of skin stripping with both products - 5% (5/106) with the adhesive hydrocellular, and 4% (4/100 with the self-adherent dressing. The results of the study reveal that the closure rates achieved with the two dressings were similar, and that both dressings were equally safe in terms of skin stripping. Independent nurse evaluations highlighted the failure of the self-adherent soft silicone foam dressing to either initially adhere to the wound area, or to remain in contact for more than a few days, and frequently needed the application of additional tape to ensure adhesion. The failure of the self-adhesive soft silicone foam dressing to adhere to the periwound area was a significant deterrent to staff to use this type of dressing routinely.

Evaluating the effectiveness of a dressing for use in malodorous, exuding wounds.

Malodorous, exuding wounds can cause problems for patients in terms of discomfort and social isolation. A prospective, noncomparative, multicenter study was conducted to evaluate the effectiveness of an odor-controlling dressing in the management of patients with chronic and acute exuding, malodorous wounds. Forty-six patients with various malodorous wounds (mean duration prior to study entry of 231.6 weeks) participated in the study. The majority of the patients were > 65 years of age (mean 70.7 years). Wound characteristics, odor, and dressing exudate absorption were assessed at baseline and at every dressing change (total: 348 dressing changes). Overall assessment of the dressing's ability was rated as good or excellent for odor control (91% of patients), exudate management (82%), and overall comfort (86%). Patient and nurse perception of odor were similar. While appropriate treatment to address the cause of exudate and wound odor remains a priority, the results of this study suggest that discomfort and isolation may be reduced through the use of odor-control dressings.

[Collagen powder: hydrocolloidal dressings. Their effectiveness in radiodermatitis].

The authors analyze the effectiveness of a collagen cicatrizant powder for use in treating radiodermatitis compared with extra fine hydrocolloidal dressings by evaluating skin lesions according to the Radiation Therapy Oncology Group (RTOG) intensity scale. As the same time, the authors evaluate the patient's opinion regarding the treatment he/she receives. This study was carried out in the Valladolid University Clinical Hospital's Department of Radiotherapy. This study showed that the Catrix brand dressing is more effective than hydrocolloidal dressings as a treatment of lesions caused by radiodermatitis. Both the nursing personnel and patients involved in this study rated this Catrix product higher than those hydrocolloidal dressings products tested.
