The oft-repeated historic development of the pneumatic lower body compression suit (MAST, PASG) for the presumed treatment of hypotension has been well-documented by McSwain(l). While the experimental and anecdotal clinical observations of Crile, Gardner, Wangenstein and Kaplan are interesting, they are not prospective, controlled, randomized clinical trials in humans(2,3,4,5). In the early 1970s, the EMS community was ripe for the bandwagon reflex to grasp at any and all gimmicks and gadgets which became available, regardless of a lack of evidence regarding their safety or danger to patients. Inventions such as the esophageal obturator airway, various darts, MAST, external cardiac bumpers, percutaneous trachea obturators, and many others simultaneously were thrust upon the unsuspecting and unprotected patient community. Some of these innovations may have been beneficial but others were dangerous. Contending that some intervention in a “life threatening, good Samaritan situation” was better than no interventional treatment or “stabilization” at all, the paramedics' blind faith in these modalities persisted. The Medical Device Amendment of 1976 (6), which requires safety and efficacy for devices, similar to that long in effect for new drugs, had not yet been enacted into law to require premarketing clearance of new medical devices. Building on blind faith and premature recommendations regarding in the unproven concept of MAST, the EMS community exercised poor judgment in recommending to state legislators that this unproven device be “required equipment” on board ambulances. Furthermore, this small cadre of “special interest groups” lobbied to have the MAST mandated as essential equipment in trauma centers(7,8). Although the minutes of the trauma planning meetings do not reflect the debate at the American College of Surgeons Committee on Trauma, numerous voices of advised constraint, said “go slow” on including the MAST as part of the ATLS course and the ACS optimal resources document.

In general, preparations for disasters which result in mass casualties do not incorporate a modern resuscitation approach. We explored the life-saving potential of, and time limits for life-supporting first aid (LSFA), advanced trauma life support (ATLS), resuscitative surgery, and prolonged life support (PLS: intensive care) following the earthquake in Armenia on 7 December 1988. We used a structured, retrospective interview method applied previously to evaluation of emergency medical services (EMS) in the United States. A total of 120 survivors of, and participants in the earthquake in Armenia were interviewed on site (49 lay eyewitnesses, 20 search-rescue personnel, 39 medical personnel and records, and 12 administrators). Answers were verified by crosschecks. Preliminary results permit the following generalizations: 1) a significant number of victims died slowly as the result of injuries such as external hemorrhage, head injury with coma, shock, or crush syndrome; 2) early search and rescue was performed primarily by uninjured covictims using hand tools; 3) many lives potentially could have been saved by the use of LSFA and ATLS started during extrication of crushed victims. 4) medical teams from neighboring EMS systems started to arrive at the site at 2-3 hours and therefore, A TLS could have been provided in time to save lives and limbs; 5) some amputations had to be performed in the field to enable extrication; 6) the usefulness of other resuscitative surgery in the field needs to be clarified; 7) evacuations were rapid; 8) air evacuation proved essential; 9) hospital intensive care was well organized; and 10) international medical aid, which arrived after 48 hours, was too late to impact on resuscitation. Definitive analysis of data in the near future will lead to recommendations for local, regional, and National Disaster Medical Systems (NDMS).

The use of the Pneumatic Anti-Shock Garment (PASG) has created much controversy in prehospital care. It is interesting that such an inexpensive device and technique has created so much controversy regarding effectiveness when expensive devices and techniques, such as coronary artery bypass, carotid endarteroectomy, and laser angioplasty have been questioned as to effectiveness, but have not created as much controversy.

Where do we stand on the PASG today? One well-done, randomized, prospective study has been reported as several different papers. In reality, these reports originate from only one study (1-5). This is compared to more than 200 other studies, many of which have been randomized, prospective studies in animals using the same quality as the randomized, prospective study done on humans. Such studies have the advantage of having better isolation of the specific condition being studied. It does not seem appropriate to base the clinical use or non-use on just one study. All studies should be reviewed and placed in context when attempting to identify the role the PASG has in patient care.

The roles of the veterinary sciences in disasters and emergencies related to exposures of the environment to harmful chemicals are reviewed. Characteristics of chemical emergencies which require the use of the veterinary sciences are discussed. Veterinary services are important in the: 1) definition of the kind and severity of the pollution through biological monitoring; 2) use of animals as monitors of the environment; 3) use of changes in the health status of animals for identification of pathophysiologic changes to man and other animals (sentinels); 4) maintenance of the hygiene of elements of the food chain; 5) evacuation and management of animal populations; 6) disposal of carcasses; and 7) treatment and follow-up of involved animal populations. Veterinary services are important components of responses to incidents marked by chemical pollution and must be included in the development of contingency plans to meet the demands created by chemical pollution.

Medical communications associated with a collision between a passenger train and three locomotives which resulted in the death of 16 and injury to at least 177 persons quickly overwhelmed the relatively sophisticated EMS communications center (SYSCOM) serving the state of Maryland, U.S.A. Other than traditional talk-by and ambulance-hospital communications, the system was saturated by: 1) communications between seven prehospital sectors; 2) persons moved into the field from their usual in-hospital environment who were not familiar or experienced with the use of radio communications; 3) traffic generated through the operations of 11 helicopters; and 4) the usual confusion that accompanies such events. The use of cellular telephones during this incident, substantially enhanced all levels of communications. Many of the participants expressed preference for this form of communications compared to the use of radios.

Problems associated with the use of cellular telephone communications included an insufficient number of channels made available by the telephonecommunications provider causing competition with non-essential personnel for use, and relatively short battery life. These problems can be solved by the provider opening more channels and by the use of larger power sources such as automobile storage batteries. It is concluded that portable and vehicle-mounted cellular telephones can serve as useful communications tools in mass casualty and disaster situations.
