Peripherally inserted central catheters (PICCs) are becoming common and effective in acute and critical care settings recently. Burn patients need special considerations because of restricted insertion sites, burn wounds, hyper coagulation, high infection rates and others. However, the safety of PICCs in burn patients are not well elucidated and no related protocol has been formed. This study aims to investigate the thrombosis and infections of PICCs in burn patients. ⋯ PICCs in burn patients had acceptable incidence of UEVT and CLABSI with relative long line durations. A standardized PICC guideline for burn patients is required to further improve the feasibility and safety of PICCs.

Delays in treatment of burn injuries can lead to significant morbidity, loss of function, and poor aesthetic appearance. Preventing conversion from partial- to full-thickness burns may help mitigate these sequelae. The pathophysiology of burn wound conversion remains unknown, but an overactive immune response is thought to be implicated. The purpose of this study was to determine whether downregulating the immune response via tacrolimus can decrease burn wound conversion. ⋯ Utilizing a combination treatment of tacrolimus and microcapillary hydrogel is able to rescue the negative effects of aging and prevent partial- to full-thickness burn wound conversion. Hopefully these findings will encourage deeper investigation into the possible therapeutic advantages of utilizing immunosuppressive agents to decrease morbidity after burn injuries. Future research will need to specifically investigate IL-2 as an inhibitory target in the acute inflammatory cascade of burn injury.

Burn care is a relatively small, mutidisciplinary field with variability in practices between centers. Given these factors, survey studies are frequently used to better understand practice variations, establish guidelines, and direct future research. If survey research is poorly designed or reported, it limits the ability to form meaningful conclusions. This study evaluates the quality of survey studies published in burn care and determines areas of improvement to increase generalizability. ⋯ Survey reporting in the burn care literature is generally inconsistent, limiting the ability to apply this research into practice.

Various studies have reported discordant results on the magnitude and direction of burn-induced coagulopathy (BIC), which has recently been associated with multiple organ dysfunction syndrome (MODS) and death. The increased mechanistic understanding of BIC is due, in part, to novel assays that have expanded the armamentarium beyond traditional tests like PT and aPTT. Still, BIC is a dynamic process, and the progression is difficult to define in the thermally-injured. ⋯ Taken together, novel coagulation parameters may be more sensitive than PT in characterizing coagulopathy in the setting of burns. The data presented herein makes initial strides to report the natural history of several of these variables over time in a large animal model of extensive burns, indicating early hypercoagulability followed by hypocoagulation. Future work will elucidate the effects of standard of care.
