Efficacy of a fibrin hemostatic bandage in controlling hemorrhage from experimental arterial injuries.

OBJECTIVE: To determine if a pressure dressing containing fibrinogen and thrombin could provide more effective control of arterial hemorrhage than a pressure dressing alone in an animal model of arterial injury. DESIGN: Randomized acute (nonsurvival) experiment in swine. SETTING: Federal biomedical research institute. ANIMALS: Six anesthetized Yorkshire swine. INTERVENTIONS: Uncontrolled arterial hemorrhage was induced in anesthetized swine by creating femoral artery lacerations. Hemorrhage was controlled by a gauze bandage containing fibrinogen and thrombin, applied with 1 minute of 3.5-kg pressure. The dressings were left in place for 1 hour after the pressure was removed. The contralateral limbs received identical treatment with plain gauze dressings. MAIN OUTCOME MEASURES: Total blood loss, mean arterial pressure, and mortality were measured after 1 hour. RESULTS: After 1 hour, blood loss in the fibrin bandage group was 123 +/- 48 mL, compared with 734 +/- 134 mL in the control group (P = .0022). In the group treated with the fibrin bandages, there was no significant decrease in the mean arterial pressure after arterial laceration. In contrast, there was a decrease of 30 mm Hg in the group treated with gauze dressings alone. There was no animal mortality during the study period. CONCLUSIONS: Bandages containing fibrinogen and thrombin significantly reduced the amount of blood loss and allowed mean arterial pressures to be maintained in animals with uncontrolled hemorrhage from femoral artery lacerations. A hemostatic bandage may be an important adjuvant for controlling severe extremity hemorrhage in the prehospital setting.

[Role of elastic compression in the treatment of postphlebitic leg ulcers at the University Hospital of Dakar: report of 20 cases].

Varicose disease and venous thrombosis were reputed exceptional among black africans and almost all leg ulcers were called "tropical". We have treated 20 cases of postphlebitic ulcers in the teaching hospital of Dakar between march 1989 and december 1992. There were 12 men and 8 women. Mean age was 40 years (24 to 60 years). The initial venous thrombosis dated at mean 8 +/- 3 years. It was confirmed in a hospital in 10 cases and found in the medical history of all patients. All patients presented leg ulcers with non systematised venous varicose and trophic troubles. The ulcers treated only by dressings lasted a duration of 4 months (2 weeks to 9 months) without healing. In view of this failure we have added an ambulatory elastic contention with elastic bandage putted on at hospital after that biweekly dressing until cicatrisation followed by putting elastic socking with degressive compression. We have observed a quickly cicatrisation in mean time of 4 weeks (2 to 6 weeks) with good tolerance of socking. Only 3 patients showed recurrence. Elastic contention has a great place in the treatment of postphlebitic ulcers which are not that exceptional among black Africans.

Porous removable rigid dressing for complicated below-knee amputation stumps.

For management of complicated below-knee amputation stumps, a porous removable rigid dressing has been fabricated that can be suspended with a supracondylar cuff or with a waist belt. In addition to permitting frequent observation, eliminating the need for elastic stump bandaging, and maintaining the advantage of the conventional rigid dressing of soft-tissue immobilization to reduce the pain and prevent trauma to the stump, the porous removable rigid dressing facilitates edema reduction and wound healing, prevents moisture building, permits frequent change of dressings and promotes fast stump shrinkage.

Biologic dressings and skin substitutes.

Burn wounds require coverage for healing to occur. Many techniques have been utilized to achieve such a closed wound, including biologic dressings, autologous skin, and skin substitutes. These and other methods are discussed.

The physical effects of an adhesive dressing top layer on burn wound dressings.

Three hydrogels were assessed in respect of water-vapour transmission and conformability. These materials were tested alone and as part of a bilaminate dressing which incorporates an adhesive top layer. The adhesive layer used in this study was a compliant adhesive bandage, marketed under the name Mefix. It was observed that this layer reduced the normally high water-vapour transmission rates of the hydrogels to much lower, clinically more acceptable, levels. Mechanically, the Mefix layer protects the underlying hydrogel, prevents tearing and puncturing but decreases conformability by elastic restraint.

Compression and peri-ulcer skin in outpatients' venous leg ulcers: results of a French survey.

OBJECTIVE: To evaluate concordance with compression therapy in ambulatory patients with venous leg ulcers. METHOD: This was a prospective observational survey conducted in general practice. Consecutive patients with venous leg ulcers about to receive a non-adherent primary dressing and with no contraindication to compression bandaging were selected. At the inclusion visit, size, local aspect of the ulcer and the peri-ulcer skin were scored. Patients were asked about concordance with compression and were given a questionnaire to be completed at home. If patients were seen at a three-week follow-up visit, ulcer and peri-ulcer characteristics and concordance were reassessed. RESULTS: A total of 2842 patients were included, of whom 2532 were re-evaluated at three weeks and 1397 (49%) returned their questionnaire. A compression bandage was already available for 62.9% of these patients, and 62.7% said they used it on a daily basis, 23.3% wore it one or two days per week and 13.7% wore it irregularly or never. There was a statistically significant correlation between concordance with compression and ulcer and peri-ulcer skin severity scores (p < 0.001 and p = 0.042 respectively). At the follow-up visit, concordance with compression therapy improved (80.1% were wearing it regularly). Ulcer, peri-ulcer skin severity scores and ulcer size were significantly lower (p < 0.001) when concordance with compression therapy was good. However, 65.6% of patients considered applying compression very difficult; 45% considered it very unaesthetic and 23% judge wearing it to be very painful, while 9% thought it may worsen their ulcer. CONCLUSION: On a short-term basis, concordance with compression can be substantially improved by simple measures with a clear favourable consequence on both ulcer status and peri-ulcer skin aspect when a non-adherent primary dressing is used. However, the acceptability of compression to patients is poor, and continuous effort is required to convince them of its importance.

Tolerability and efficacy of hydrocolloid dressings in the treatment of venous leg ulcers under tropical conditions: an open prospective study.

In the Western world, hydrocolloid dressings are widely used in wound treatment. However, little is known about their tolerability and efficacy under tropical conditions. The purpose of this study was to assess the tolerability and efficacy of a hydrocolloid dressing in combination with short stretch compressive bandages under tropical conditions. Seventeen patients with venous leg ulcers attending an outpatient clinic in Surinam were enrolled in the study for a period of 6 weeks. Swabs for bacterial cultures were taken at the beginning and end of the study. All ulcers showed a good healing tendency. Percentage of granulation tissue in the ulcers improved from mean 27% at start to 92% at the end. Mean circumference at start was 9.9 cm, at the end 4.9 cm. Exudation diminished from moderate in six and severe in eight ulcers, to moderate in 10 and almost none in two ulcers. In general, the dressing was very well accepted, pain was never reported. Leakage was noticed 39 times in the 164 dressing changes. This study revealed no differences in the rate of bacterial infections or colonization of wounds compared with studies performed in temperate regions. Our data indicate that hydrocolloid dressings can be used under tropical conditions.

Detection of aerosolized varicella-zoster virus DNA in patients with localized herpes zoster.

We examined the excretion of varicella zoster virus (VZV) in hospitalized patients with herpes zoster localized to the thoracic region whose skin lesions were covered with either hydrocolloid dressing agents (hydrocolloid group) or conventional gauze bandages (gauze group). The presence of VZV DNA in swab samples from lesion coverings, the throat, and filters of air purifiers was examined by use of a sensitive polymerase chain reaction assay. For the hydrocolloid group, VZV was detected in none of the samples from lesion coverings or air purifier filters; for the gauze group, VZV DNA was detected in samples from gauze coverings and air purifier filters for all 6 patients. VZV DNA was detected less frequently in throat samples from patients in the hydrocolloid group than in those from patients in the gauze group. The results of the present study suggest that hydrocolloid dressing agents prevent excretion of aerosolized VZV DNA from skin lesions of patients with localized herpes zoster.

Controlled prospective trial of wound management in elective hand surgery.

A total of 33 consecutive patients undergoing elective hand operations were randomly allocated 5 days after the operation either to have all dressings discarded or to continue with an occlusive bandage for a further 2 weeks. Assessments at 2 and 6 weeks showed that wound healing, hand function, symptoms and complications were identical in both groups. It was concluded that for selected patients early removal of hand dressings after surgery does not have any deleterious effects.
