摘要:
This study evaluated the antimicrobial activity of ACTICOAT Antimicrobial Barrier Dressing (Westaim Biomedical Corp, Fort Saskatchewan, Alberta, Canada), a silver-coated wound dressing, and compared it with silver nitrate, silver sulfadiazine, and mafenide acetate. The minimum inhibitory concentrations (MIC), minimum bactericidal concentrations (MBC), zone of inhibition, and killing curves were determined with 5 clinically relevant bacteria. The data indicate that ACTICOAT silver had the lowest MIC and MBC and generated similar zones of inhibition to silver nitrate and silver sulfadiazine. Viable bacteria were undetectable 30 minutes after inoculation with the dressing, whereas it took 2 to 4 hours for silver nitrate and silver sulfadazine to achieve the same result. Mafenide acetate generated the biggest zones of inhibition, but it had the highest MICs and MBCs, and a significant number of bacteria still survived after 6 hours of treatment. The results suggest that ACTICOAT Antimicrobial Barrier Dressing has better antimicrobial performance than either of the existing silver-based products. ACTICOAT dressing killed the bacteria that were tested much faster, which is a very important characteristic for a wound dressing acting as a barrier to invasive infection to have. The study also suggests that a single susceptibility test such as a MIC or zone of inhibition test does not provide a comprehensive profile of antimicrobial activity of a topical antimicrobial agent or dressing. A combination of tests is desirable. (J Burn Care Rehabil 1999;20:195–200)

摘要:
Since the concept of a fabricated skin replacement was first proposed, it has been recognized that a permanent skin replacement must contain a functional complex structure consisting of epidermis integrated with dermis. Although a practical solution for the replacement of missing epidermis exists through the culture expansion of the autologous epidermis, a practical solution for permanently replacing missing dermis has not been achieved. While it is generally recognized that the insoluble matrix components—largely collagen and elastin—are essential, the role of other matrix components such as glycosaminoglycans (GAGs) and proteoglycans remains undefined. This article describes both the qualitative and quantitative GAG composition of fresh and cryopreserved human dermis. Through the use of 2 different colorimetric assays and cellulose acetate electrophoresis, we found the following: 1) the principal dermal GAGs are those of the heparin family; 2) dermatan sulfate is the second most predominant GAG component; 3) chondroitin-6-sulfate is found at concentrations of 2 orders of magnitude less than the heparins; and 4) hyaluronan and keratan sulfate were both found as only minor constituents. When the GAG composition of fresh skin was compared with that of cryopreserved skin, no significant differences were observed. This study also examined the time course of GAG leaching during the preparation of deconstructed human dermis, which is human dermis reduced to the native insoluble matrix components by exhaustive saline soaking. We found that GAG leaching was readily detectable even within the first day. Sixty percent of total GAG leaching occurred by day 7. These investigations establish a benchmark for the reproduction of GAGs in synthetic dermal constructs. Further, the results of the leaching study generate important considerations for short-term skin storage and long-term skin banking. Because GAG leaching commences immediately, appropriate precautions must be taken to minimize the potential functional compromise of cryopreserved human dermis. (J Burn Care Rehabil 1999;20:201–6)

摘要:
Clinical assessment of burns is accurate for very deep and very shallow burns, but it has been suggested that there is a high degree of inaccuracy in the assessment of dermal burns. Histologic analysis has, by some, been considered too time-consuming for routine diagnosis. It also requires an expert skin histopathologist to categorize the depth. With the use of an in vitro model, we have found the use of cryosections and an immunofluorescent staining method to be quicker and more clear-cut than standard light microscopic techniques. We believe this method plays a role in helping to define burns that would benefit from early excision and grafting. However, further investigation is required to transform the method from an experimental model to standard practice in the clinical setting. (J Burn Care Rehabil 1999;20:207–11)

摘要:
An 18-year-old male was involved in a single car motor vehicle accident in which the driver's side airbag was deployed. He presented to the trauma center with complex injuries to the left hand, lacerations to the scalp, and a full-thickness burn to the ulnar aspect of the right hand that included the hypothenar area and the fifth digit. The patient was admitted to the trauma center and received immediate consultation from the burn service. He underwent débridement and split-thickness skin grafting of 50 cm2of the right hand on postburn day 3. The graft became necrotic and the patient underwent débridement of the skin and the abductor minimi muscle of the right hand on postburn day 32. Split-thickness skin grafting and release of flexion contracture were successfully completed 18 days later. The police and fire departments reported that the airbag showed signs of thermal destruction. Upon request, Honda motors submitted information from the TRW safety systems and material safety data sheet (Mesa, Ariz, issued 1989) that showed that airbag canisters contain the chemicals sodium azide and cupric oxide. Water may react with sodium azide to form highly toxic and explosive hyfrazoic acid. These chemicals are converted to sodium hydroxide, which can cause significant chemical burns. In addition, these chemicals may ignite when exposed to live electrical wires or temperatures greater than 300°F. We conclude that burns associated with damaged deployed airbags in motor vehicle accidents may be the results of both chemical and thermal injury. The extent of the burn wound may be underestimated, as our case illustrates. Full-thickness burns resulting from airbag deployment may require more aggressive initial débridement and treatment.

摘要:
For a 10-year period, the cases of 236 patients aged 60 years old or older were evaluated with regard to mortality and length of hospital stay. Multiple variables were evaluated. Total mortality for the entire group was 41.9%. Mortality was adversely affected by increased age and the development of complications after admission. Larger burn size increased mortality when it was considered in association with the presence of inhalation problems sufficiently severe to require a ventilator. Mean length of stay for survivors was 34.04 days. Length of stay (LOS) was increased in association with larger burn size, preexisting medical problems, and the development of complications after admission. The increase in the number of elderly patients as part of the in-hospital burn population mandates evaluation of this growing group. (J Burn Care Rehabil 1999;20:218–23)

摘要:
The impact of partial-thickness facial burns on the behavior of adults was investigated. Burn injuries of the face often have a deleterious effect on the psychologic well-being of the patient. Even when no skin grafting is performed, there seems to be significant deterioration of the physical and emotional function of adults after they have incurred partial-thickness burns of the face.

摘要:
Although chemical injuries account for only a small number of one burn unit's cases, the diversity, resulting complications, and sequelae of these burns pose special problems. We reviewed a 19-year period of the chemical burn experience of our burn unit. The population of patients with these types of burns consisted of young men (mean age: 29.8 years), the majority of whom were injured on the job. Unique to our series is the largest collection of injuries (30%) resulting from the common fertilizer anhydrous ammonia. Another population of concern, accounting for 14% of the injuries in our unit, is that of patients injured at home with routine household cleaners. Nearly one half of those patients injured at home incurred injuries that required grafting. The cornerstone of chemical burn prevention and treatment involves education regarding the caustic nature of chemicals, proper handling, adequate protection, and copious irrigation of the wound at the scene. From the analysis of our retrospective review, adequate education and treatment at the scene appear to be well implemented in the industrial and farming communities. The focus of our education efforts should be directed toward the public and emphasize the safe use of household chemicals. Finally our review illuminated the potential benefit of immediate excision and grafting for decreasing the length of stay, complications, and loss of productivity.

摘要:
The objective of this study was to present data that showed high frequency percussive ventilation (HFPV) was superior to traditional mechanical ventilation for the treatment of children with inhalation injuries. Inhalation injuries continue to be the number one cause of death of patients with thermal injuries in the United States. Therapy for this condition has consisted of conservative pulmonary toilet and mechanical ventilation. Despite improvements in the management of burn injury, patients with inhalation injury develop pneumonia and pneumothorax, leading to adult respiratory distress syndrome. Unfortunately, inhalation injury that is complicated by pneumonia has been shown to increase mortality by 60% in these patients. Cioffi has shown that prophylactic use of HFPV in adult patients with inhalation injury has been a successful method of reducing the incidence of pneumonia and mortality. The effects of HFPV on the incidence of pneumonia, peak inspiratory pressures, and arterial partial pressure of oxygen/fraction of inspired concentration of oxygen (P/F) ratios were retrospectively studied in 13 children with inhalation injuries and compared with historic controls treated with conventional mechanical ventilation. All patients were treated with our standard inhalation injury protocol and extubated when they met standard extubation criteria. Patients ranged in age from 6 to 9 years, and most had burns covering greater than 50% of their total body surface areas. No deaths occurred in either group, but the patients who were treated with HFPV had no cases of pneumonia (P< .05), better P/F ratios (P< .05), lower peak inspiratory pressures, and less work of breathing (P< .05) as compared with our control group. On the basis of our clinical experience and data, the use of HFPV seems to be an effective treatment for the reduction of pulmonary morbidity in pediatric patients with inhalation injuries.
