Application of a First Impression Triage in the Japan Railway West Disaster
On April 25, 2005, a Japanese express train derailed into a building, resulting in 107 deaths and 549 injuries. We used “First Impression Triage (FIT)”, our new triage strategy based on general inspection and palpation without counting pulse/respiratory rates, and determined the feasibility of FIT in the chaotic situation of treating a large number of injured people in a brief time period. The subjects included 39 patients who required hospitalization among 113 victims transferred to our hospital. After initial assessment with FIT by an emergency physician, patients were retrospectively reassessed with the preexisting the modified Simple Triage and Rapid Treatment (START) methodology, based on Injury Severity Score, probability of survival, and ICU stay. FIT resulted in shorter waiting time for triage. FIT designations comprised 11 red (immediate), 28 yellow (delayed), while START assigned six to red and 32 to yellow. There were no statistical differences between FIT and START in the accuracy rate calculated by means of probability of survival and ICU stay. Overall validity and reliability of FIT determined by outcome assessment were similar to those of START. FIT would be a simple and accurate technique to quickly triage a large number of patients

Cerebral resuscitation from cardiac arrest: Treatment potentials
In 1961, in Pittsburgh, PA, ``cerebral'' was added to the cardiopulmonary resuscitation system (CPR right arrow CPCR).Cerebral recovery is dependent on arrest and cardiopulmonary resuscitation times, and numerous factors related to basic, advanced, and prolonged life support. Postischemic-anoxic encephalopathy (the cerebral postresuscitation disease or syndrome) is complex and multifactorial. The prevention or mitigation of this syndrome requires that there be development and trials of special, multifaceted, combination treatments. The selection of therapies to mitigate the postresuscitation syndrome should continue to be based on mechanistic rationale. Therapy based on a single mechanism, however, is unlikely to be maximally effective. For logistic reasons, the limit for neurologic recovery after 5 mins of arrest must be extended to achieve functionally and histologically normal human brains after 10 to 20 mins of circulatory arrest. This goal has been approached, but not quite reached. Treatment effects on process variables give clues, but long-term outcome evaluation is needed for documentation of efficacy and to improve clinical results. Goals have crystallized for clinically relevant cardiac arrest-intensive care outcome models in large animals. These studies are expensive, but essential, because positive treatment effects cannot always be confirmed in the rat forebrain ischemia model. Except for a still-elusive breakthrough effect, randomized clinical trials of CPCR are limited in their ability to statistically document the effectiveness of treatments found to be beneficial in controlled outcome models in large animals. Clinical studies of feasibility, side effects, and acceptability are essential. Hypertensive reperfusion overcomes multifocal no-reflow and improves outcome. Physical combination treatments, such as mild resuscitative (early postarrest) hypothermia (34 degrees C) plus cerebral blood flow promotion (e.g., with hypertension, hemodilution, and normocapnia), each having multiple beneficial effects, achieved complete functional and near-complete histologic recovery of the dog brain after 11 mins of normothermic, ventricular fibrillation cardiac arrest. Calcium entry blockers appear promising as a treatment for postischemic-anoxic encephalopathy. However, the majority of single or multiple drug treatments explored so far have failed to improve neurologic outcome. Assembling and evaluating combination treatments in further animal studies and determining clinical feasibility inside and outside hospitals are challenges for the near future. Treatments without permanent beneficial effects may at least extend the therapeutic window. All of these investigations will require coordinated efforts by multiple research groups, pursuing systematic, multilevel research--from cell cultures to rats, to large animals, and to clinical trials. There are still many gaps in our knowledge about optimizing extracerebral life support for cerebral outcome.(Crit Care Med 1996; 24(Suppl):S69-S80
