Transillumination-guided intubation is a useful back-up method when laryngoscopic intubation proves to be difficult or impossible. The Trachlight™ (Laerdal, N-4001 Stavanger, Norway) is suited for both nasal and oral use. Intubation times (intubation time) and success rates (success rate) for nasal and oral intubation with the Trachlight were compared.
Twenty-four medical students, inexperienced in intubation were instructed in the use of the Trachlight. A demonstration also was performed. Subsequently, they were asked to intubate a Laerdal Airway Management Trainer™ (Laerdal, Stavanger, Norway) using the Trachlight. Each student intubated 10 times orally and 10 times nasally (five times through the right and five times through the left nostril). The succession of the students was randomized The intubation times were measured and the position of the tube noted. Nasal and oral intubation times for the tenth trial (steady state conditions) were compared using the rank-order test for paired observations. Oral and nasal success rates were compared using the sign test for paired observations.
The differences between nasal and oral intubation concerning intubation time and the success rates were not significant. Nasal intubation with the Trachlight seems to be more difficult than the oral intubation.
To study the effects of early, advanced prehospital life support on the survival rate of war casualties during the battle of Jalalabad, Afghanistan from 1989–1992.
Method:
The outcomes of simple trauma care administered from 1989–1990 were compared to the outcomes of advanced trauma care administered from 1991–1992 in the combat zone. The outcomes were measured by the number of deaths at admission to the referral surgical hospitals in Pakistan.
Results:
A total of 3,890 war casualties were treated in the combat zone by paramedics, and were evacuated through light, forward, field clinics to surgical hospitals in Pakistan. Advanced trauma care that was administered in the combat zone reduced the prehospital mortality rate from 26.1% to 13.6% (95% confidence interval for difference = 9.7–15.4%).
Conclusion:
In scenarios with protracted evacuation, early and advanced trauma care should be included in the chain of survival. Local paramedics can provide such trauma care with a minimum of resources.
The past decade has been a period of evolution for the Federal disaster response system within the United States. Two domestic hurricanes were pivotal events that influenced the methods used for organizing Federal disaster assistance. The lessons of Hurricane Hugo (1989) and Hurricane Andrew (1992) were incorporated into the successful response to Hurricane Marilyn in the U.S. Virgin Islands in 1995. Following each of these storms, the Department of Defense was a major component of the response by the health sector. Despite progress in many areas, lack of clear communication between military and civilian managers and confusion among those requesting Department of Defense health resources may remain as obstacles to rapid response.
Methods:
This discussion is based on an unpublished case report utilizing interviews with military and civilian managers involved in the Hurricane Marilyn response.
Results:
The findings suggest that out-of-channel pathways normally utilized in the warning and emergency phase of the response remained operational after more formal civilian-military communication pathways and local assessment capability had been established.
Conclusion:
It is concluded that delays may be avoided if the system in place was to make all active pathways for the request and validation of military resources visible to the designated Federal managers located within the area of operations.
Adenosine has received wide acceptance as the drug of choice for initial treatment of supraventricular tachycardias (supraventricular tachycardia), and as a diagnostic adjunct in hemodynamically stable, wide-complex tachycardias. This report describes the successful use of adenosine for the treatment of supraventricular tachycardia occurring after successful initial resuscitation from ventricular fibrillation, in which a high dose of the epinephrine protocol was used.
Fluid therapy in uncontrolled bleeding is controversial. In a previously used experimental animal model of aortic injury, the outcome often was impaired by re-bleeding that began at least 20 minutes after crystalloid fluid resuscitation was initiated. Therefore, it was hypothesized that re-bleeding might be avoided if volume loading is carried out for 20 minutes and then disconstinued.
Methods:
Ten minutes after a 5 mm laceration was produced in the infra-renal aorta on eight anesthetized pigs, they received a 20-minute intravenous infusion of Ringer's solution in the ratio of 1:1 to the expected blood loss. Hemodynamics were studied for 120 minutes using arterial and pulmonary artery catheters and blood flow probes placed proximal and distal to the aortic lesion and around the left renal artery and portal vein.
Results:
The bleeding stopped between three and four minutes after the onset of bleeding. The blood flow rate dropped to 38% (mean) of baseline in the splanchnic region, to 31% in the upper aorta, and to 13% in the kidney. The flow rates and the oxygen consumption increased transiently during fluid resuscitation, but never reached baseline levels. Re-bleeding amounted to about 15% of the initial bleeding and occurred in only three of the animals. Four of the pigs died of shock within 90 minutes (range 47–85 minutes) after the aortic injury.
Conclusion:
Short-term crystalloid fluid therapy in uncontrolled aortic hemorrhage transiently improved the hemodynamic status and the oxygen consumption following the initial bleeding. Furthermore, the infusion did not cause re-bleeding of more than 100 ml, which occurred in previously conducted experiments when the infusion was continued for more than 20 minutes.
Reports of medical care at mass gatherings reflect variability in mission and delivery models. Equipment recommendations are similarly varied. Thoughtful pre-planning and experience-based analysis are the best mechanisms for defining general and specific equipment recommendations.
Objective:
This report presents a suggested supply and equipment list developed over a six-year period of medical coverage at an air show, with an emphasis on the usage and cost of expendable supplies.
Methods:
The authors were involved in the planning for and execution of emergency medical care for a large, local, military air show on an annual basis, including provision of expendable medical supplies. A list of such supplies was developed over the initial two to three years, formalized and refined over the subsequent two years, and analyzed in the final, highest patient volume year of coverage. Detailed usage and cost was tracked over the final year for expendable supplies.
Results:
The results of this analysis indicate that comprehensive emergency medical care from first aid to mass casualty care can be offered at reasonable equipment and supply costs, if existing equipment resources can be supplemented by expendable supplies from a pre-determined list. Given the need for large quantities of supplies for a mass casualty contingency and the low likelihood of occurrence, a loan arrangement with a supplier, with return of unused supplies, is particularly convenient and economical. The approach used in this study should be appreciable in other similar settings. In concurrent scheduled events, the iterative process described can lead to greater specificity of needs for expendable supplies.
The people oFf Africa are exposed to a wide range of disasters that seriously have aggravated the Continent's economic situation. Economic losses and human sufferings from drought, desertification, locust infestation, infectious diseases, epidemics, and armed conflicts are the dominant disasters that the people in the African countries face, and they have rendered the population utterly vulnerable. Disasters have aggravated Africa's economic situation. The cumulative effect of disasters include loss of property, injury, death, mounting food import bills, health hazards, environmental degradation, backward economic development, displaced people, refugees, and nutritional deficiency.
Today, 175 million Africans out of a total population of 744 million people (23.5%) are suffering from chronic hunger; this is an increase of 50% from 25years ago. In many African countries, up to half of the population suffers from absolute poverty. It is projected that Africa will be the only Continent to continue with the current level of poverty for another decade.
Disasters always have been a part of life, whether caused by unavoidable natural events or by avoidable, man-made events. Being rendered helpless by such events has caused fear and concern in all periods of history. To some extent, a disaster is expected, but there are varying degrees of uncertainty as to how and when it will occur. The occurrence of a disaster creates varying degrees of chaos combined with a mismatch between resources and needs. Therefore, in order to restore an affected society back to its pre-event status requires extraordinary efforts.
Medical Miranda, also called Secondary Emergency Notification of Dispatch (Secondary Emergency Notification of Dispatch), is a low cost, effective, and welcome addition to emergency medical dispatching systems. The benefits are recognized by emergency medical dispatchers who receive feeder calls from associated public safety agencies that have trained both their field staff and call-takers in the Medical Miranda protocol.
Hypothesis:
The dispatchers would be more satisfied with feeder agencies that used the Secondary Emergency Notification of Dispatch protocol.
Methods:
A survey was conducted and analyzed, taking advantage of a situation in which two agencies (one used Secondary Emergency Notifi-cation of Dispatch) fed calls to the same communication center.
Results:
Dispatchers were more satisfied with the information gained from the feeder agency that used the Secondary Emergency Notification of Dispatch protocol and believed that the officers and dispatchers of that agency had afar better understanding of the emergency medical dispatcher's needs.
Conclusions:
When the emergency medical dispatcher does not talk directly with the reporting scene personnel or caller, Medical Miranda increases the usefulness of the information the dispatcher receives, helps the dispatcher better understand the reported medical emergency, and improves response appropriateness in emergency medical service (Emergency Medical Service) systems where responses routinely are prioritized.
This is a report of three patients in a surgical ward of a hospital who developed complications seemingly related to the use of full-face-fitting masks associated with the first Scud Missile attack on Israel durng the Gulf War. Patient 1 developed atrial fibrillation with an uncontrolled ventricular rate; Patient 2 redeveloped a gastrointestinal hemorrhage; and Patient 3 developed a severe anxiety attack. Each of the three was severely ill prior to the event. Special attention should be given to severely ill patients during such events.
Mr. Chairman, Ladies and Gentlemen, first let me thank you for coming to this meeting that has been organized by us in close collaboration with UYDP, OCHA, UNIGEF and IDNOR with generous support from the Canadian, UK, and USA development agencies. It always is a pleasure to recognize our partners.
We have with us here today representatives of a large number of agencies, institutions, NGOs, and private individuals. This cross section of interests is a manifestation of a growing and irreversible trend. The important issues of our time cannot be dealt with solely by nations, agencies, or individuals, even the most powerful ones. The phenomenon of globalization no longer is restricted to economic or financial matters: it is now evoking the wide participation of ranges and numbers of actors that would have been unthinkable a few decades ago. In almost all aspects of our work, we are looking to find the partners and interests that can bring value to the management of the issue or the search for solutions, if definitive solutions ever can be found to the really important human challenges.
