Resuscitation from burn shock using fresh frozen plasma (FFP) has been described. Critics of FFP resuscitation cite the development of transfusion related acute lung injury (TRALI) as a deterrent to its use. This study examines the occurrence of TRALI with FFP resuscitation of critically ill burned patients. ⋯ The possible occurrence of TRALI in burn patients receiving FFP resuscitation should be weighed against the reported benefits of such a resuscitation strategy.

To evaluate the efficacy of mannitol solution as a decontamination agent on the chemical burn of the human corneas. ⋯ In eye bank human corneas, mannitol proved to be an efficient agent to decontaminate HF burn.

The prevalence of antibiotic-resistant organisms (ARO) in burn units is increasing worldwide and contributes significantly to morbidity and mortality. Study aims are to describe the burden of AROs in burn patients admitted to a tertiary burn unit, to evaluate the impact of contact precautions implemented after an outbreak of antibiotic-resistant Acinetobacter baumannii, and to identify possible predictors of ARO acquisition. ⋯ This study describes the ARO profile of burn patients admitted to a tertiary burn unit. The results suggest that implementation of unit-wide contact precautions may not significantly reduce the frequency of AROs among burn patients. Contact precautions for patients transferred from the ICU, undergoing surgery, and large burns may be of benefit.

Burns cause physiologic changes in multiple organ systems in the body. Burn mortality is usually attributable to pulmonary complications, which can occur in up to 41% of patients admitted to the hospital after burn. Patients with preexisting comorbidities such as chronic lung diseases may be more susceptible. We therefore sought to examine the impact of preexisting respiratory disease on burn outcomes. ⋯ Preexisting chronic respiratory disease significantly increases the hazard of progression to mechanical ventilation and mortality in patients following burn. Given the increasing number of Americans with chronic respiratory diseases, there will likely be a greater number of individuals at risk for worse outcomes following burn.

The NLRP3 inflammasome is a multi-protein complex that assembles in response to tissue damage or infection, triggering activation of caspase-1, an enzyme that converts interleukin (IL)-1β into its active form. A role for the NLRP3 inflammasome is emerging in inflammatory pain, but its influence in other pain types is largely unexamined. Therefore the aim of this study was to assess the role of the NLRP3 inflammasome and its downstream product caspase-1 in a model of acute burn-induced pain in male mice. ⋯ Burn-induced edema was significantly reduced in Ice-/- mice only. Burn-induced weight bearing changes were attenuated in Nlrp3-/- mice and mice administered MCC950 72h after burn only. This study suggests that NLRP3 and its downstream product caspase-1 have a limited role in the development of burn-induced pain.
