NOTICE: The project that is the subject of this report was approved by the Governing Board of the National Research Council, whose members are drawn from the councils of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The members of the committee responsible for the report were chosen for their special competences and with regard for appropriate balance.
The Institute of Medicine was chartered in 1970 by the National Academy of Sciences to enlist distinguished members of the appropriate professions in the examination of policy matters pertaining to the health of the public. In this, the Institute acts under both the Academy's 1863 congressional charter responsibility to be an adviser to the federal government and its own initiative in identifying issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine.

While the individuals listed above have provided constructive comments and suggestions, it must be emphasized that responsibility for the final content of this report rests entirely with the authoring committee and the Institute of Medicine.
The U.S. military has a long tradition of making the safety of its troops a top priority. This goal is evident in military strategy and tactics and in the development of sophisticated technology that decreases or avoids human risk. This commitment is evident in the fostering and support of biomedical research that is applicable to the military as well. The spectrum of supported research ranges from acute through chronic care of the soldier. The U.S. Department of Veterans Affairs, for example, invests in research on long-term rehabilitation from wounds or military-related disease, whereas the armed services often focus on the acute medical needs of the injured soldier. One of the most important goals involves immediate resuscitation of the wounded soldier in the field, to support life during transport to a field facility, where definitive treatment may be instituted by highly trained medical personnel. The Office of Naval Research asked our committee to focus on this immediate resuscitation to ensure that current care is optimal and that future research is focused in the most fertile areas for advancement.
The National Academy of Sciences (NAS) has a long history of assisting the military in the evaluation of methods of resuscitation and shock. NAS volunteered its expertise to President Woodrow Wilson in 1916, and he responded by asking NAS to organize scientific agencies for national defense. At the conclusion of World War I in 1918, the president, by executive order, asked the Academy to perpetuate the National Research Council (NRC) for the government to have a consulting body available for a variety of needs. NRC played an important role in the studies of shock and resuscitation prior to and during World War II and provided advice for research policy and treatment protocols.
The challenges associated with the immediate resuscitation of the wounded soldier are daunting and are often unappreciated by civilian medical personnel. Military engagements often take place in mud, rain, snow, heat, or cold, at sea or on beaches, and often at night. The field medics, who are responsible for ini-
tial resuscitation and treatment, can carry only very limited medical gear, and they are often engaged in battle and under fire while attempting to treat the wounded. Thus, the need for simple, compact, and effective approaches for immediate resuscitation is apparent.
Research in this area is extraordinarily challenging. First, there are few, if any, ways in which all aspects of human hemorrhagic shock can be fully reproduced in the laboratory. Various animal models can mimic specific aspects of the shock process, but no single model represents the entire spectrum of human hemorrhagic shock; there remain fundamental differences that apparently cannot be narrowed. Yet the use of unproven treatments in the field is simply unacceptable.
The committee had two goals as it thought about research in this area. First, it wanted to indicate to the Office of Naval Research which technologies were best suited for use in the immediate future. Second, it wanted to give some direction for longer-term research by identifying promising areas that might lead to leaps in the knowledge about hemorrhagic shock or care for the combat casualty. As part of the committee's review of the state of the science, the committee held a 2-day conference and heard from more than 40 scientists, medical researchers, and clinicians in the field of resuscitation research. Subsequently, the committee solicited information from several additional scientists and from the scientific community at large. In the end, the committee felt comfortable with its grasp of current research and with its view of the opportunities for future investigation. These conclusions are presented in the text of this report.
Finally, the committee wanted its work to have some relevance to the civilian medical community. Although its first responsibility was to the military, the committee understood that there are both similarities and differences between civilian emergency trauma care and acute military medicine. With this in mind, the committee was explicit in describing the similarities and differences between the combat and civilian environments, and it offered suggestions for technologies or approaches that would apply to civilian care as well. The committee hopes that this report will help energize and focus research in both military and civilian emergency medical care and help to save the lives of citizens and soldiers alike.
On behalf of the committee, I wish to express our gratitude to all who contributed to the production of this report. First, we appreciate the opportunity that was presented by the Office of Naval Research, which initiated the questions and sponsored the project. Second, a review of the science would not be possible if it were not for the many scientists and experts whose findings formed the scientific basis of this report. Third, the arduous process of conducting the complex task was made easier by the talented staff of the Institute of Medicine, especially Andy Pope, Geoff French, and Glen Shapiro. Most importantly, I want to add my personal gratitude to the rest of this committee who volunteered countless hours of their time and expertise to produce this document.
If the work that we have done here serves to assist in resuscitating even one casualty that would have otherwise been lost, as we believe it will, then this will have been a successful and worthwhile endeavor.
