[Quantitative effect of a standardized pressure bandage on arterial and venous circulation in the lower extremities after heart catheter examination].

AIM: The aim of the study was to evaluate the effect of a conventional pressure dressing on arterial and venous blood flow of the legs after cardiac catheterization. METHODS: Duplexsonographic measurements were performed of both legs in 100 consecutive patients before catheterization and with a pressure dressing after the procedure. The pressure dressing was applied by means of a pressure pad on the punctured leg, so that the ankle-arm-index (blood pressure at the leg/blood pressure at the arm) was not influenced. Arterial and venous blood flow of the superficial femoral artery and vein were registered. We evaluated both legs by means of duplex sonography to detect arterial or venous complications after cardiac catheterization. Statistical evaluation was performed using the 1-sample Wilcoxon test. RESULTS: There was a significant reduction of venous blood flow in the punctured leg from a mean of 119 ml/min before puncture to 84 ml/min during pressure dressing (29% flow reduction, p < 0.01), and a reduction of arterial blood flow from a mean of 132 ml/min before puncture to 84 ml/min during pressure dressing (36% flow reduction, p < 0.01). In the contralateral leg, venous blood flow was reduced from about 118 ml/min to 96 ml/min during pressure dressing (19% flow reduction, p < 0.01), and arterial blood flow was reduced from about 129 ml/min to 93 ml/min during pressure dressing (28% flow reduction, p < 0.01). There were no venous complications, 5 patients suffered false aneurysm (5%), and one patient had an arteriovenous fistula (1%). CONCLUSION: A conventional pressure dressing caused a significant reduction of arterial as well as venous blood flow of both the punctured leg and the contralateral leg. This is of clinical relevance especially in patients with known peripheral arterial disease or patients at risk for deep venous thrombosis.

Simple pressure bandage technique for free skin grafts.

We applied sterile packed cellulose sponges in the dehydrated state as a pressure dressing from skin grafts by using the classic "tie-over" technique. At the end of the procedure, the sponges were hydrated, and provided flat, even pressure to a localized area. By using this simple technique, we obtained 26 of 27 successful free skin grafts with flat apposition.

Planimetric rate of healing in venous ulcers of the leg treated with pressure bandage and hydrocolloid dressing.

BACKGROUND: Venous leg ulcers are a common cause of morbidity, but few predictive parameters exist that can be used to follow their progress. OBJECTIVE: We investigated the use of healing rate as a useful parameter in the treatment of venous ulceration. METHODS: Twenty-seven venous ulcers being treated with a standard regimen were evaluated. We calculated the initial (4-week) and overall healing rates using the Gilman method (delta A/p). RESULTS: The average initial healing rate for all ulcers combined, the healed group, and the nonhealing group was 0.069, 0.087, and -0.005 cm/wk, respectively. Similarly, the average overall healing rate for all ulcers combined, the healed group, and the nonhealing group was 0.062, 0.089, and -0.043 cm/wk, respectively. CONCLUSION: The initial healing rate (delta A/p(0-4)) may be an appropriate end point for clinical investigations comparing therapies for the treatment of chronic venous leg ulcers.

A controlled, randomized, comparative study of a radiant heat bandage on the healing of stage 3-4 pressure ulcers: a pilot study.

OBJECTIVES: Pressure ulcers, like other chronic wounds, fail to proceed through an orderly and timely process to produce anatomical or functional integrity. Treatment of pressure ulcers is directed to improving host factors and providing an optimum wound environment. In addition to providing a moist wound environment, it has been theorized that preventing hypothermia in a wound and maintaining a normothermic state might improve wound healing. DESIGN/SETTING: Forty-one subjects with a stage 3 or stage 4 truncal pressure ulcer >1.0 cm(2) were recruited from outpatient clinics, long-term care nursing homes, and a rehabilitation center. The experimental group was randomized to a radiant-heat dressing device and the control group was randomized to a hydrocolloid dressing, with or without a calcium alginate filler. Subjects were followed until healed or for 12 weeks. RESULTS: Eight subjects (57%) in the experimental group had complete healing of their pressure ulcer compared with 7 subjects (44%) with complete healing in the control group (P = .46). CONCLUSION: Although a 13% difference in healing rate between the two arms of the study was found, this difference was not statistically significant. At almost all points along the healing curve, the proportion not healed was higher in the control arm.

Use of the Megasoft Bandage Lens for treatment of complications after trabeculectomy.

Shallow anterior chambers and leaking filtration blebs are possible complications after trabeculectomy that can be treated with therapeutic contact lenses. In most cases, however, treatment fails because these lenses are not large enough to cover the filtering bleb. We evaluated the use of a newly developed large diameter (20.5 mm) therapeutic soft contact lens. Five patients with shallow anterior chambers and ten patients with leaking filtering blebs after trabeculectomy were fitted with this new extended-wear contact lens. All patients with shallow anterior chambers developed deep chambers after a mean treatment period of five days. Of the ten patients with leaking filtering blebs, in eight (80%) the leak closed after a mean treatment period of 2.2 months. The contact lens used was comfortable and complications occurred in only one eye. This new therapeutic device is an improvement in the treatment of complications after trabeculectomy.
