[Occlusive dressing--s potential treatment for tympanic membrane rupture?].

In a rat study, an occlusive double-layer transparent hydrocolloid dressing, Duo-DERM, was compared with a rice paper dressing in the treatment of tympanic membrane perforation. The Duo-DERM dressing manifested better healing properties, and the healed membrane was histologically similar to spontaneously healed membrane, being generally thin with moderate connective tissue thickening. If this dressing is found to have good healing properties in clinical trials, it would mean a great saving in health care resources. The method is simple, inexpensive, and gives immediate improvement in hearing.

Evaluation of a new hydrocolloid occlusive dressing for central catheters used in total parenteral nutrition.

Catheter-related sepsis still remains one of the most frequent and serious complication of total parenteral nutrition. Strategies for preventing contamination of central venous lines have focused on decreasing the number of micro-organisms around the exit site and inhibiting their entry into the catheter wound. This prospective study compares a new occlusive hydrocolloid dressing (Visiband; Convatec Squibb) with that of a polyurethane film dressing for nutritional catheters. Dressings were changed either on day 3 or day 5 after application. Swab smears of the catheter exit site at each dressing change were stained by Gram's method before inoculation onto a blood agar plate, a chocolate agar plate and a MacConkey agar plate. Significantly less colonisation occurred under the former dressing at day 3 and day 5 dressing changes. In addition, the polyurethane film dressing was associated with a significant increase in skin colonisation (P = 0.04) and the number of positive Gram-stain microbes if left unchanged for 5 days (P = 0.0018). Staphylococcus aureus catheter-related sepsis occurred in 1 patient on day 18 in the polyurethane film dressing group. In addition, Candida albicans colonisation was confined to patients with the polyurethane film dressing. While the type of dressing applied to the catheter exit site may influence the incidence of catheter colonisation and infection, it must be emphasised that strict adherence to aseptic technique during catheter insertion and manipulation of the dressing is vital in the prevention of catheter-related sepsis during total parenteral nutrition.

[Comparison of occlusive dressing and vaseline gauze on the skin graft donor site wound healing].

OBJECTIVE: To observe the effect of occlusive environment on wound healing of the skin graft donor site. METHODS: The wound healing of the skin graft donor site in adults was studied by clinic observation, histological, histochemical and electromicroscopical examinations. RESULTS: The wound under an occlusive moisture environment healed faster and the inflammation was more serious at the early stage of wound healing while the macrophages appeared more and earlier. CONCLUSIONS: The wound of a skin graft donor site in an occlusive moist condition would heal faster than that covered with conventional Vaseline gauze. The more serious inflammation and the more macrophages may be related to the result.
