Reproducibility of transpulmonary thermodilution measurements in patients with burn shock and hypothermia.
Thermal noise, including hypothermia and short-term variations in body temperature, has been reported to influence the accuracy and reproducibility of thermodilution measurements. This variation might theoretically limit the usefulness of this technique in patients with acute burns. We therefore sought to determine the reproducibility of hemodynamic parameters derived from arterial thermal dilution in patients with acute burns and hypothermia. ⋯ A maximum of 12.9% was found at 48 hours after burn. No correlation was found between body core temperature and the reproducibility of intrathoracic blood volume index (r = 0.145), cardiac index (r = 0.217), or extravascular lung water index (r = 0.167). The parameters derived from arterial thermodilution show a clinically sufficient reproducibility in patients with acute burns associated with thermal instability.

Evaluation of cytotoxicity and antimicrobial activity of Acticoat Burn Dressing for management of microbial contamination in cultured skin substitutes grafted to athymic mice.
Cultured skin substitutes (CSS) have become a useful adjunctive treatment for closure of burn wounds, but CSS are avascular and remain susceptible to microbial destruction longer than split-thickness skin grafts. Irrigation of CSS grafted to burn wounds with a topical antimicrobial solution (TAS) has been shown to promote engraftment of CSS, but TAS usage has potential limitations. Acticoat Burn Dressing (Acticoat; Westaim Biomedical, Exeter, NH) is a silver-coated barrier dressing reported to exhibit antimicrobial activity and to reduce infection in partial-thickness and full-thickness wounds. ⋯ Contaminated wounds treated with Acticoat healed similarly to control treatments, with comparable rates of engraftment, and detection of SBI-N on the surface of only one graft. No SBI-N was detected on CSS after inoculation onto the surface of Acticoat. These results suggest that Acticoat may be suitable as a protective dressing to reduce environmental contamination of CSS, if used in conjunction with additional antimicrobials to control organisms present in the wound.

Methamphetamine laboratory explosions: a new and emerging burn injury.
The proliferation of clandestine methamphetamine laboratories (meth labs) as a result of the growing popularity of the drug has resulted in an increasing incidence of burn injuries associated with laboratory accidents. We undertook this study to characterize these injuries. Fifteen consecutive patients were identified and case-matched by age and TBSA to 45 control subjects. ⋯ Meth lab injury is unique and requires more critical care resources. It also is associated with lack of insurance coverage and poor follow-up after injury. This injury has a significant impact not only on patients but also on the healthcare system.

Natural disasters have always been a threat. human-caused disasters, especially terrorist acts, are increasing in frequency. Burn centers and providers have an important contribution to make in caring for those injured in these incidents. The most effective way to make a contribution is to act in cooperation with the Federal Disaster Response, which is organized by the Department of Homeland Security and the Federal Emergency Management Agency. It appears that this can be most effectively accomplished through participation in the Burn Specialty Team Program, which has been developed to rapidly augment emergency medical teams with burn expertise.
