Operating room fires can have devastating consequences and as such must be prevented. There exists a paucity of literature requiring further elucidation regarding manufacturer recommendations of a predefined waiting period prior to patient draping after using alcohol-based surgical antiseptics, in order to reduce the risk of operating room fires. ⋯ In conclusion, our data suggest an average dry time of less than 1-min, with ignition only observed when the antiseptic was visibly wet. Ignition did not occur on hairless skin with electrocautery on CUT mode using ChloraPrep at any time point. Additionally, ignition on hair-bearing skin was not observed past 3 min, with current manufacturer recommendations stating 1 h wait time for hair-bearing skin. Arbitrarily waiting a specific predetermined dry time until patient draping, as recommended by the manufacturers, may be unnecessary and lead to hours' worth of time wasted each year. Ongoing research will further investigate the utility of drying the antiseptic after application and its affect on not only preventing ignition but also antimicrobial efficacy.

Case Reports
Delayed Pressure Urticaria Associated With Altitude Chamber Training Responsive to Cyclosporine and Omalizumab.
Delayed pressure urticaria (DPU) is a subset of chronic inducible urticaria. It is characterized by the formation of wheals anytime between 30 minutes and 24 hours after stimulus exposure of localized pressure application. In this case report, we discuss a military flight crew member with no significant past medical history who developed DPU following rapid decompression in an altitude chamber. ⋯ Control of symptoms was achieved through combination treatment of a second-generation antihistamine, a leukotriene receptor antagonist, and an immunosuppressant (cyclosporine). His waiver to return to flight status was denied while on cyclosporine. He was transitioned to a monoclonal antibody that binds free immunoglobin E (omalizumab) with resolution of symptoms and was cleared to return to active duty.

Debridement plays a critical role in wound management. In addition to removing necrotic tissue, debridement can eliminate bacteria frequently harbored within the tissue. This study evaluated a novel debridement method that uses plasma-based radiofrequency technology to remove tissue and bacteria. Coblation is a technology that uses radiofrequency energy to excite the electrolytes in a conductive medium, such as saline, to create a precisely focused plasma. This plasma field contains highly energized particles that possess sufficient energy to break tissue molecular bonds, causing the tissue to dissolve at relatively low temperatures (typically 40 °C to 70 °C). ⋯ Reducing MRSA bacterial infection counts, especially of biofilm-associated organisms, in combination with shrapnel may have important clinical implications, especially for the military personnel. Further research into the use of this technology in wound management is warranted.
