Effective resuscitation is critical in reducing mortality and morbidity rates of patients with acute burns. To this end, guidelines and formulas have been developed to define infusion rates and volume requirements during the first 48 hours postburn. Even with these standardized resuscitation guidelines, however, over- and under-resuscitation are not uncommon. ⋯ Because the system can self-adjust based on monitoring inputs, the technology can be pushed to environments such as combat zones where burn resuscitation expertise is limited. A closed-loop system can also assist in the management of mass casualties, another scenario in which medical expertise is often in short supply. This article reviews the record of fluid balance of contemporary burn resuscitation and approaches, as well as the engineering efforts, animal studies, and algorithm development of our most recent autonomous systems for burn resuscitation.

Comparative Study
Nonoperative treatment of multiple intra-abdominal solid organ injury after blunt abdominal trauma.
A number of large series' have attempted to examine the management of blunt solid organ injuries; however, only a few studies regarding multiple injuries exist. The aim of this study is to analyze whether multiple solid organ injury affects nonoperative management (NOM) and to look for predictive factors of NOM. ⋯ Lactate levels at admission, solid viscus score, necessity of transfusion, crystalloid resuscitation, and a drop in the hematocrit in the first hour after admission are useful parameters for judging the failure of NOM. Although there is a higher failure rate of NOM in multiple solid organ injury, NOM can still be considered in these cases with extra caution.

An epidemiologic profile of traumatic brain injury (TBI) in Australia and New Zealand was obtained following the publication of international evidence-based guidelines. ⋯ In Australia and New Zealand, mortality and favorable neurologic outcomes after TBI were similar to published data before the advent of evidence-based guidelines. A high incidence of prehospital secondary brain insults and an ageing population may have contributed to these outcomes. Strategies to improve outcomes from TBI should be directed at preventive public health strategies and interventions to minimize secondary brain injuries in the prehospital period.

Outcome in patients with traumatic brain injury (TBI) is often affected by secondary insults including posttraumatic cerebral infarction (PTCI). The incidence of PTCI after TBI was previously reported to be 2% with no mortality impact. We suspected that recent advances in imaging modalities and treatment might affect incidence and outcome. We sought to define the incidence and mortality impact of PTCI. We also identified risk factors associated with PTCI. ⋯ The incidence of PTCI in patients with severe TBI is higher after severe brain injury than previously thought. PTCI has a significant impact on mortality and LOS. The presence of a blunt cerebral vascular injury, the need for craniotomy, or treatment with factor VIIa are risk factors for PTCI. Recognition of this secondary brain insult and the associated risk factors may help identify the group at risk and tailor management of patients with severe TBI.
