Meta-analysis of randomized controlled trials on hydrocolloid occlusive dressing versus conventional gauze dressing in the healing of chronic wounds.

Chronic wound management is a difficult area in surgical practice. A wide range of dressings have been recommended for the management of chronic wounds. The present meta-analysis was undertaken to determine the effectiveness of hydrocolloid dressing (HCD) in the healing of chronic wounds compared with conventional gauze dressing. All available controlled clinical trials published before December 2001 that compared HCD to conventional gauze dressing in the healing of chronic wounds were systematically reviewed. We identified and analysed 12 randomized trials (11 published; 1 unpublished) comprising 693 patients with 819 ulcers. The overall odds ratio under the fixed effect model was 1.72, that is, 72% more ulcers healed completely with HCD than with conventional gauze dressing. This result was both clinically and statistically significant.

Semipermeable occlusive dressings. Effects on growth of pathogenic bacteria and reepithelialization of superficial wounds.

Six commercially available semiocclusive dressings were tested for their effect on the growth of resident and pathogenic bacteria and the reepithelialization of experimentally induced wounds in human volunteers. Scarification and abrasion-type wounds inoculated with Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus pyogenes, and Pseudomonas aeruginosa were quantitatively cultured at different times after being covered with the dressings. Reepithelialization was assessed by serial stereomicrographs. None of the dressings was able to prevent clinical infection. All dressings provided microenvironments that were conducive to the growth of resident and pathogenic bacteria. There was no difference in the rates of reepithelialization.

Optimal use of an occlusive dressing to enhance healing. Effect of delayed application and early removal on wound healing.

We examined the effect of delayed application and early removal of a polyurethane dressing on excisional wounds in swine. Backs of pigs were wounded with an electrokeratome, and wounds were divided into the following treatment groups: (1) air exposed; (2) dressings applied immediately after wounding and kept on until wounds were evaluated; (3) dressings applied immediately after wounding and removed at 6, 24, or 48 hours; and (4) dressings applied 2, 6, and 24 hours after wounding. Wounds were excised on days 3 through 7 and incubated in sodium bromide to allow separation of the epidermis and dermis. Specimens were considered healed if no defect was present. To promote optimal resurfacing in superficial wounds, polyurethane dressings need to be applied within two hours after wounding and should be kept in place for at least a 24-hour period.

The influence of occlusive dressing and hyperbaric oxygen on flap survival and the healing of ischaemic wounds.

The effect of dressing with Duoderm (hydrocolloid) and treatment with hyperbaric oxygen was investigated on the healing of ischaemic incisional wounds and on flap survival in rats. After 10 days, Duoderm dressing of ischaemic wounds decreased all strength parameters (load*S, stress*S) by 41%-44% and the improvement of ischaemic wound healing by hyperbaric oxygen treatment shown in our previous study was not seen. After removal of Duoderm on day 10 the biomechanical properties had improved but not returned to normal on day 20. In the dressed animals the shrinkage of ischaemic wounds and the extension of necrosis on the ischaemic flaps were reduced. Dressing may be useful clinically in preventing superficial dermal necroses. One must, however, be aware of the impairment of the wound strength of the incisional wounds.

Onset of the vasoconstrictor effect of diflucortolone valerate, betamethasone valerate, and fluocinolone acetonide ointments applied for varying periods under occlusive dressings.

Evaluation of cutaneous vasoconstriction after applications of varying duration of topical corticoids on the flexor surfaces of the forearms of 20 patients with intact skin shows a significantly faster blanching effect with diflucortolone valerate ointment than with fluocinolone acetonide and betamethasone valerate ointments. Furthermore, the test shows that even for a highly active preparation, such as the diflucortolone valerate ointment, an application time of less than 3 h only exceptionally leads to vasoconstriction in the healthy skin.

[Treatment of 3rd degree fingertip frostbite in a mountain climber with semi-occlusive dressings].

Deep frostbites of the fingertips mostly result in some form of amputation. To preserve functional length and to achieve good sensibility, we managed deep frostbites of five fingertips of a mountain climber with semiocclusive dressings. The method was described by Mennen and Wiese (1993) for the management of fingertip injuries. To our knowledge, the method has not been used so far in the treatment of frostbites. The two fingertips presenting only deep soft-tissue damage achieved a nearly normal recovery of pulp shape and sensibility. The three fingers with bone involvement required a long period of time for complete healing. In two of these fingers, additional bone shortening had to be performed.

Treatment of psoriasis and other dermatoses with a single application of a corticosteroid left under a hydrocolloid occlusive dressing for one week.

Lotions of five different corticosteroids were applied on 3 X 4 cm areas of large infiltrated chronic psoriatic plaque in eight patients, and left occluded with a hydrocolloid dressing (Actiderm) for one week. Area treated with clobetasol, betamethasone and triamcinolone were clinically healed within one week in four patients, but slight residual erythema was observed in the other four. Hydrocortisone-treated areas showed better improvement than the non-steroid-treated control area, where infiltration and erythema remained unchanged. In 44 patients with psoriasis, lichen planus, chronic lichenified eczema, discoid lupus erythematosus and necrobiosis lipoidica, treatment with betamethasone applied 1-3 times under Actiderm once a week healed the lesions. The skin-coloured Actiderm is easy to apply and wear and does not loosen when taking a shower or hot bath.

[Treatment of fingertip defect injuries with a semi-occlusive dressing].

In the treatment of substance loss of fingertips it is crucial to maintain functional length and to restore adequate sensibility. By treating those injuries with a semiocclusive dressing according to Mennen and Wiese (1993), we were able to achieve both goals with excellent results, avoiding the necessity of local or regional flaps as well as shortening of bone to achieve primary closure. 82 patients with 85 injured digits were treated either conventionally (primary closure with or without shortening of bone, vaseline gauze dressings: 31 digits) or with semiocclusive dressings (54 digits). 42 digits of the latter group with complete protocols were evaluated at the end of treatment. 26 digits with defects of skin and subcutaneous tissue of less than 1 cm2 to more than 2 cm2 necessitated an average of 18 days until complete healing (minimum 6, maximum 46 days). Eight digits with loss of skin, subcutaneous tissues and nailbed healed within 10 to 32 days (average 22 days) and eight digits in which defects included bone loss averaged 49 days for complete healing (37 to 64 days). No complications, especially no infections have been observed. All healed finger-tips were well padded, painless, many without visible scar and with static two-point discrimination between 2 and 8 mm.

A hydrocolloid occlusive dressing plus triamcinolone acetonide cream is superior to clobetasol cream in palmo-plantar pustulosis.

The purpose of this study was to compare the therapeutic efficacy of a hydrocolloid dressing (Actiderm) over a medium strength corticosteroid (triamcinolone acetonide (TAA) 0.1% cream) with that of a highly potent corticosteroid (clobetasol propionate 0.05% cream) in palmo-plantar pustulosis and localized pustular psoriasis. It was a randomized, open, prospective, right-left comparative trial in 19 patients. The Actiderm dressing and the TAA cream were applied every third day, whereas the clobetasol cream was applied twice daily for 4 weeks. Both treatments resulted in a significant improvement. On completion of treatment, complete clearance was found in 13 patients (63%) with Actiderm plus TAA, but in only 3 patients (21%) with clobetasol (p = 0.001). Four weeks after stopping therapy, the clinical parameters had returned to their pre-treatment level, except for erythema on the Actiderm plus TAA treated lesions (p less than 0.05). No clinically important adverse effects were reported or observed; in particular there was no sign of skin atrophy at the end of study. The results of this study demonstrate that Actiderm applied over a medium strength corticosteroid every third day is highly effective against palmoplantar pustulosis and localized pustular psoriasis. However, it is necessary to develop treatment regimens to maintain the improvement achieved.

Evaluation of a flexible new liquid polymer wound dressing.

Occlusive dressings are the foundation of wound care and have been shown to speed epithelialization and healing of surgical sites. Many different dressings have been introduced over the years including antibacterial ointments with gauze and adhesive, hydrocolloid bandages, and liquid adhesives. All of these have their limitations and advantages. We introduce our experience with a new organic polymer in solvent which when applied to a wound forms a flexible occlusive bandage. The material has been shown to have antimicrobial properties and be well-tolerated by patients.

[Comparative clinical and exfoliative cytological studies on the use of occlusive dressings].

Among the variety of surgical packs described in the literature, zinc oxide-based packs have proved especially useful. Two types still currently used are the zinc oxide-eugenol pack according to Büchs and Walter and the pack modified by Behlke which contains Peruvian balsam in place of eugenol. Of 27 patients who had undergone a periodontal-surgical intervention, 6 were treated with a zinc oxide-eugenol pack, and 21 with a pack modified by Behlke. Clinical and cytological examinations were performed before intervention, at each change of pack (on the 5th, 8th and 14th days after intervention) and 4 weeks after intervention. The comparison of the results obtained shows the superiority of the pack modified by Behlke over the zinc oxide-eugenol pack.
