ReviewClinical algorithm for initial fluid resuscitation in disasters.
This article reviews past experience with branch-chain decision trees for fluid resuscitation of various emergency conditions and analyzes the effects of compliance with the algorithm on mortality and shock-related complications. On the basis of this analysis, the authors propose a new algorithm for fluid resuscitation of mass casualties when only palpable systolic blood pressure is available and when blood pressure, hematocrit, central venous pressure, urine output, and arterial blood gases are available.

A disaster that produces a multitude of patients may severely stress a community's health-care system, from the EMS system to the hospitals. Physicians involved in such an event must realize that they will have to change their normal mode of delivering care, having to make decisions with less than the normal amount of information, and doing the most good for the most salvageable patients. Some understanding of and appreciation for the unique problems that face emergency personnel in the field are important for physicians who do not normally interact with fire and EMS personnel, because it will allow them to realize that they are not alone in the chaos of a disaster. ⋯ Hospital physicians can do much to prepare themselves for these eventualities. Discussion and planning should be done among separate staffs (ICU, operating suite, emergency department), as well as among staff of the various disciplines so they can interact more effectively when a disaster occurs. Local disaster planners should receive input from hospital staffs so hospital capabilities are known and the field operation can mesh well with the hospital's operation.

Evaluation of a blunt and penetrating trauma algorithm for truncal injury.
The authors objective was to develop and test a single branch-chain decision tree for blunt and penetrating truncal injury. Over the 4-month study period there were 979 patients evaluated in the emergency department; 674 of these patients were admitted to the hospital. Thirty-four (5%) of the 674 admitted patients died of truncal injury. ⋯ Of the 44 patients managed with major deviations from the algorithm, 27 (61%) died. Only 14 of the 195 patients (7%) whose management complied with the algorithm died. The authors conclude that following the specific management criteria outlined by the algorithm may improve the survival of severely traumatized patients.

As previously discussed, the majority of injury cases do not necessarily involve dramatic life-saving actions, but rather very rudimentary, promptly applied precautions. For most victims of trauma, therefore, we offer reassurance and simple compassion in their time of need. One of the more important lessons to be learned here is that, beyond prehospital injury "management" or "treatment," we should always remember to provide the best possible prehospital injury care. ⋯ Successful transport of disaster victims, whether in the prehospital phase or during interhospital transfer, requires careful attention to treatment priorities, such as simple measures for airway control and ventilation, and care to prevent further injuries by appropriate immobilization techniques. The use of fully equipped teams of multidisciplinary critical care specialists in mass disaster situations is in its infancy. It is clear that with properly adapted hardware and personnel trained to function in adverse environments while effectively delivering intensive care to a large number of patients with a variety of clinical syndromes, survival can be significantly increased for the most acutely ill.
