Published: July 2016

AbstractIntroduction:The safe and timely provision of blood is of crucial importance in the prevention and mitigation of morbidity and mortality due to trauma. The use of blood in the treatment of war casualties, soldiers as well as civilians, was analyzed retrospectively and the impact of massive blood transfusion on blood banking services and reserves of blood during the war in Sarajevo was assessed.Methods:A retrospective analysis of 3,215 war casualties (1,815 civilians plus 1,400 military) who arrived to the casualty reception center of the State Hospital of Sarajevo during the period 11 May through 31 October 1992 was performed. Blood usage was reviewed in three stages: within 24 hours (h) of admission, after seven days of hospitalization, and after 30 days of hospitalization. The types of injury, survival rate, and blood-usage rate in a sample of 37 war casualties who required massive blood transfusions (MBT) during the period 11 May through 31 December 1992 was examined.Results:The civilian casualty rate in this series of patients was 56.5%. A total of 1,217/3,215 (37.9%) casualties were hospitalized. In this study, 16% (504/3,215) of total number of persons wounded received blood transfusion. Of these patients, 504/1,217 (41.4%) were transfused. A total of 971.1 liters of blood were transfused through 31 October 1992; 68% within 24 h of admission, 91% within the first seven days, and 100% within the first 30 days. From a total of 37 MBT recipients, 36 (97%) were injured by firearms. Survival rate among MBT patients was 30%. The MBT recipients comprised 2% of total hospitalized patients and 6% of total number of patients transfused. The amount of blood needed during episodes of MBT was 15% of total blood used through 31 December 1992.Conclusions:Based on these data, prospective requirements for blood usage should take into account casualty triage, as follows: for each casualty transported to the hospital, hospitalized, or transfused, 0.302, 0.796, and 1.912 liters of blood respectively, will be needed for the first 30 days of treatment. Recipients of massive blood transfusions are a significant drain on blood reserves in war. This experience can be utilized in the development of revised guidelines for blood usage for an entire population affected by war.
Emergency Medical Services Liability Litigation in the United States: 1987 to 1992
Authors: Morgan David L. , Wainscott Michael P. , Knowles Heidi C. 
Published: July 2016

AbstractIntroduction:Although emergency medical services (EMS) liability litigation is a concern of many prehospital health care providers, there have been no studies of these legal cases nationwide and no local case studies since 1987.Methods:A retrospective case series was obtained from a computerized database of trial court cases filed against EMS agencies nation-wide. All legal cases that met the inclusion criteria were included in the study sample. These cases must have involved either ambulance collisions (AC) or patient care (PC) incidents, and they must have been closed between 1987 and 1992.Results:There were 76 cases that met the inclusion criteria. Half of these cases involved an AC, and the other cases alleged negligence of a PC encounter. Thirty (78.9%) of the plaintiffs in the AC cases were other motorists, and 35 (92.1%) of the plaintiffs in the PC cases were EMS patients. Almost half of the cases named an individual (usually an emergency medical technician or paramedic) as a codefendant. Thirty-one (40.8%) of the cases were closed without any payment to the plaintiff. There were five cases with plaintiffs' awards or settlements greater than [US] $1 million. Most (71.0%) ofthe ACs occurred in an intersection or when one vehicle rear-ended another vehicle. The most common negligence allegations in the PC cases were arrival delay, inadequate assessment, inadequate treatment, patient transport delay, and no patient transport.Conclusion:Risk management for EMS requires specific knowledge of the common sources of EMS liability litigation. This sample of recent legal cases provides the common allegations of negligence. Recommendations to decrease the legal risk of EMS agencies and prehospital providers are suggested.

AbstractIntroduction:In large disasters, such as earthquakes and hurricanes, rapid, adequate and documented medical care and distribution of patients are essential.Methods:After a major (magnitude 6.7 Richter scale) earthquake occurred in Southern California, nine disaster medical assistance teams and two Veterans Administration (VA) buses with VA personnel responded to staff four medical stations, 19 disaster-assistance centers, and two mobile vans. All were under the supervision of the medical support unit (MSU) and its supervising officer. This article describes the patient-data collection system used. All facilities used the same patient encounter forms, log sheets, and medical treatment forms. Copies of these records accompanied the patients during every transfer. Centers for Disease Control and Prevention data classifications were used routinely. The MSU collected these forms twice each day so that all facilities had access to updated patient flow information.Results:Through the use of these methods, more than 11,000 victims were treated, transferred, and their cases tracked during a 12-day period.Conclusions:Use of this system by all federal responders to a major disaster area led to organized care for a large number of victims. Factors enhancing this care were the simplicity of the forms, the use of the forms by all federal responders, a central data collection point, and accessibility of the data at a known site available to all agencies every 12 hours.

Published: July 2016

AbstractStudy objective:Blood pressure (BP) in the out-of-hospital setting is one of the most important diagnostic tools used by emergency medical services (EMS) providers. Conventional methods of palpation and auscultation can be time consuming, and the measurements often are inaccurate because of the adverse working conditions encountered. Pulse oximetry waveform systolic blood pressure (POWSBP) measurement has been used successfully in emergency departments to monitor BP. The objective of this study was to compare the accuracy of field POWSBP measurements obtained by noninvasive electronic BP measurement (NIBPM), auscultation, and palpation in the out-of-hospital environment.Design:Blood pressure measurements used for this study were obtained by POWSBP, NIBPM (PROPAQ model 102; Protocol Systems, Beaverton, Oregon USA), auscultation, and palpation on patients in moving ambulances. Measurement of POWSBP was accomplished by observing the return of the waveform on the pulse oximeter at the time of cuff deflation. The order in which the readings were obtained as well as the arm chosen for measurement were randomized.Setting and participants:Paramedics and emergency medical technicians in an urban, inner-city emergency medical services (EMS) system.Measurements and main results:Bloopressure measurements were sampled from 69 patients. Regression analysis identified significant correlation between POWSBP and the four methods utilized, with r = 0.92 for NIPBM, r = 0.95 for auscultation, and r = 0.97 for palpation, all significant at p<0.0001.Conclusions:The use of POWSBP measurement is a fast, easy, and accurate technique with which to measure systolic BP in the field. It may have special importance for noisy environments and moving vehicles in which conventional methods of auscultation or palpation may be difficult.

Published: July 2016

AbstractObjective:Oral endotracheal intubation (ETI) is the preferred method of controlling the airway in critically ill or injured patients. It was postulated that time could be saved if intubation was performed in the ambulance en route to the hospital. This study was designed to determine whether the ambulance environment adversely affected the ability of emergency medical technicians at the advanced-intermediate level (EMT-AI) to perform oral ETI.Hypothesis:The restrictive environment of a moving ambulance would affect adversely the ability of EMT-AIs to perform ETI compared with a controlled setting. This would result in a significant increase in the time necessary to perform ETI in the ambulance compared with a controlled setting not complicated by restrictive space and motion.Methods:Twenty on-duty EMT-AIs were recruited to volunteer for this prospective, nonrandomized, nonblinded trial. All participants performed three consecutive oral ETIs on an airway mannequin in two settings: 1) in the back of a moving ambulance; and 2) on a table in the rescue squad station. Of the participants, 10 performed the intubations in the ambulance first; the remainder performed the intubations at the station first. Time for intubation with the mannequin was recorded by stopwatch. The mean times for intubation in both settings were compared by Student's t-test (p<0.05).Results:All intubation attempts were successful. The mean time for intubation in the station was 13.0±3.4 seconds. The mean time in the ambulance setting was 13.2±5.3 seconds. There was no significant difference between the intubation times in the two settings (p = 0.88).Conclusion:The environment of a moving ambulance does not appear to hinder the ability of EMT-AIs to perform oral ETI in a laboratory setting with a mannequin model.
Enhancing Critical Thinking in Paramedic Continuing Education
Authors: Dalton Alice L. 
Published: July 2016

AbstractCritical thinking has become a buzzword, especially in medical education. The challenge is first to determine what skills compose critical thinking and what teaching techniques promote critical-thinking skills, and then to determine how to apply these techniques effectively and efficiently to a given population in the classroom.This article begins with a working definition of critical thinking and explores the parameters and skills implied or stated in the definition. Then a teaching environment constructed around a model of critical thinking and characteristics of the audience is described. A specific teaching method, suggested by research and designed to exercise critical-thinking skills, is then applied to a specific patient problem in a continuing education class. Preliminary outcomes are presented.The purpose of this article is to propose a productive and efficient educational method for promoting and enhancing critical-thinking skills appropriate for paramedic-level continuing education.

Published: July 2016

AbstractIntroduction:Although the efficacy of the administration of beta-adrenergic bronchodilators has been demonstrated, the best method available for the delivery of these drugs in the prehospital setting has not been defined. This paper compares the effects of administration of metaproterenol when administered by paramedics using either a metered-dose inhaler (MDI) or a hand-held nebulizer (HHN).Hypothesis:There is no difference in the effects produced in patients suffering from smooth bronchiolar muscle spasm by metaproterenol when delivered either by a standard metered-dose inhaler or with a hand-held nebulizer.Participants:Consecutive prehospital patients complaining of difficulty breathing with clinical evidence of bronchospasm and with a history of asthma, chronic obstructive pulmonary disease, or emphysema who were not in extremis.Methods:Prior to the administration of metaproterenol, a peak expiratory flow rate (PEFR) was obtained. This measurement was repeated five minutes following the conclusion of the administration of metaproterenol. Patients in Burbank, California, received the treatment using a standard metered-dose inhaler, and those in Madison, Wisconsin, received the drug using a hand-held nebulizer. Peak expiratory flow rates were compared using Student's t-tests with Bonferroni's correction. Statistical significance was set at p <0.05.Results:Data were collected from 36 consecutive patients by the paramedics of the Burbank Fire Department and from 32 consecutive patients by the paramedics of the Madison Fire Department. For the metered-dose inhaler group, the mean value for peak expiratory flow rate for the pre-treatment test was 95.4 ±88.1 1/min, and after treatment was 109.4 ±89.3 1/min (p <0.001). For the hand-held nebulizer group, the mean value for peak expiratory flow rate before the administration of the metaproterenol was 96.1 ±76.3 1/min and following the treatment was 149.1 ±92.9 1/min (p <0.001). The mean values for the differences between the control peak expiratory flow rate and the post-treatment peak expiratory flow rate for the metered-dose inhaler group was +14.0 ±27.4 1/min, and for the hand-held nebulizer group was +53.0 ±69.1 1/min (p <0.003).Conclusions:In the prehospital setting the administration of metaproterenol using a hand-held nebulizer is more effective than delivering the drug using a metered-dose inhaler. The hand-held nebulizer is easier to use and delivers a higher dose of the drug than is convenient using the metered-dose inhaler.
The Effects of Stressors on Emergency Medical Technicians (Part II): A Critical Review of the Literature, and a Call for Further Research
Authors: Boudreaux Edwin , Mandry Cris 
Published: July 2016

AbstractPart I of this series of articles about stress among emergency medical technicians (EMTs) reviewed the potential sources of EMT stress. This article investigates the other side of the stress equation and provides a critical review of the empirical literature on the effects of stressors on EMTs. It is subdivided into sections corresponding to trends in the research, including: 1) predictors of higher stress levels; 2) differences in stress responses among EMTs, other health professionals, and firefighters; and 3) various physiologic, psychologic, and job performance responses. It identifies some of the methodologic flaws found in the EMT-stress literature that are noted in Part I, and provides further direction for future research. To maintain homogeneity, this review is limited to those articles published in scholarly journals. Studies investigating constructs such as job dissatisfaction and burnout were not included unless the study also included a measure of stress or stressors.
Acceptance of an Injury-Prevention Program in Rural Communities: A Preliminary Study
Authors: Moore Edwin , McComas John 
Published: July 2016

AbstractIntroduction:Considerable attention is being addressed to injury prevention. This study addresses the acceptance of a home injury-prevention survey as an injury-prevention tool in rural communities.Purpose:The purpose of this study was to evaluate public acceptance of a home injury-prevention survey as a tool to educate and enlighten the public about home injuries.Methods:All patients with home injuries who came to Wetzel County Hospital Emergency Department were asked if they would participate in a home injury-prevention survey. The study was conducted from 01 May to 01 July 1995. Paramedics were used as interviewers because of the closeness they enjoy with the community.Results:During the study period, 2,104 patients came to the emergency department of Wetzel County Hospital. Of these, 386 sought care because of an injury sustained in their homes. From this group, 23 (5.9%) patients agreed to participate in a home injury-prevention study; 363 (94.1%) refused.Conclusion:A home injury-prevention survey alone does not seem to be an effective tool to aid in the reduction of home injuries, because it is not embraced by the general public.
Infant Feeding Practices in Complex Emergencies: A Case Study Approach
Authors: O'Connor Mary E. , Burkle Frederick M. , Olness Karen 
Published: July 2016

AbstractThe majority of deaths associated with complex emergencies are attributed to infants and children under the age of five years. Most of these deaths are related to preventable diseases such as malnutrition, diarrhea, and malaria. Infant feeding emergencies have emerged as a major factor in complex emergencies. This paper reviews the current information relative to infant feeding, and uses four case studies as educational tools for the management of infant feeding emergencies.Child mortality rates in refugee population have been linked directly to protein-energy malnutrition (PEM). Breast feeding has many advantages over all other forms of feeding for children up to the age of two years of age. These advantages are discussed in detail in this paper. In addition, the appropriate and inappropriate uses of breast-milk substitutes (BMS) are discussed. Breast feeding also may play a role in the spread of HIV infections from the mother to the infant. However, in the setting of complex emergencies in the developing world, the risk of an infant dying of malnutrition and infection when not breastfed is likely to be greater than is the risk of death due to HIV acquisition through breastfeeding.The physiology of lactation is reviewed with particular reference to the roles of prolactin, oxytocin, and the feedback inhibitor of lactation (FIL) hormone. No medications have been demonstrated to augment milk production that can be used in a practical sense in complex emergencies. Lastly, the principles promulgated by the WHO and UNHCR for the feeding of infants and children in emergencies and for milk powder distribution are summarized.
Demographic Methods to Assess Food Insecurity: A North Korean Case Study

Published: July 2016

AbstractIn complex emergencies, especially those involving famine and/or wide-spread food insecurity, assessments of malnutrition are critical to understanding the population's health status and to assessing the effectiveness of relief interventions. Although the Democratic People's Republic of Korea (DPRK) has benefited from some of the largest, most sustained appeals in the history of the World Food Program (WFP), the government in Pyongyang has placed restrictions on international efforts to gather data on the health and nutritional status of the affected population.Question: Lacking direct means to assess the nutritional status of the North Korean populace, what other methodologies could be employed to measure the public health impacts of chronic food shortage?The paper begins with a review of methods for assessing nutritional status, particularly in emergencies; a brief history of the North Korean food crisis (1995–2001), and a review of the available nutritional and health data on the DPRK. The main focus of the paper is on the results of a survey of 2,692 North Korean adult migrants in China. Recognizing certain biases and limitations, the study suggests that sample households have experienced an overall decline in food security, as evidenced by both the decline in government rations from an average of 120 grams per person per day to less than 60 grams per day, and by the increase in the percentage of households relying on foraging or bartering of assets as their principal source of food. It also is apparent that the period 1995–1998 has been marked by elevated household mortality, declining fertility, and steadily rising out-migration. Taken together, the signs point toward famine, whether that is defined as a discrete event—that is, as a regional failure in food production or distribution leading to elevated mortality from starvation and associated disease—or as a more complex social process whose sub-states include not only elevated mortality, but declining fertility, eating of alternative ‘famine foods’, transfer of assets, and the uprooting and separation of families.
Comparison of Emergency Resuscitation with Colloids and Crystalloids
Authors: Shoemaker William C. 
Published: July 2016

Clinical management is exceedingly difficult to evaluate in emergency patients because resuscitation is often chaotic, disorderly, and frantic. Resuscitation depends upon many factors: the primary illness or injury, the amount of blood and fluid losses, the patient's age, the prior state of health, the associated medical conditions, the time delay in instituting therapy, the volume and rate of fluids administered, and, finally, the choice of fluids given. Although it is difficult to control the effects of these complex interrelated factors, their influence may be evaluated by stratifying patients and then comparing the direct effects and outcome measures within each stratum.There has been persistent controversy over the relative merits of crystalloids and colloids in fluid resuscitation. We studied reviews of fluid management of all hypotensive patients seen in the adult surgical section of the Emergency Department (ED) during a 2½ year period, to compare the conventional crystalloid resuscitation which had been standard for this busy university-run county hospital with a fluid management protocol consisting of about 1/4 A colloids depending on age, cardiac history, and CVP.
Pathologic Studies: An Essential Guide
Authors: Moossy John 
Published: July 2016

To emphasize the importance of pathologic studies to physicians and biomedical scientists should be “preaching to the converted.” Unfortunately there are disturbing signs that this is not so, particularly in clinical medicine. The autopsy rate is declining globally and some authors have even unwisely implied in print that modern diagnostic techniques render the autopsy and other pathologic studies superfluous. Fortunately, pathologists continue to expose and resist such attitudes by means of analytical discussion of the problem. The role of pathologic study remains an essential one in both clinical and experimental studies of therapy of all types.The term pathologic studies includes: pathologic anatomy (the autopsy and surgical biopsy); clinical pathology (hematology, chemistry, microbiology, immunologyl and experimental pathology.
Role of Trauma Score in Triage of Mass Casualties
Authors: Champion Howard R. , Sacco William J. 
Published: July 2016

The development of emergency medical services (EMS) systems in the United States, incorporating various levels of sophistication in prehospital care and echelons of capability in hospital resource availability, has brought new connotations to the word “triage” (sorting).Heretofore, triage consisted entirely of estimating treatment needs so that prioritized transfer of patients could be made to hospitals. The decision is no longer binary, since the introduction of Trauma Centers requires the triage decision maker to not only decide which patient first, but also which patient to which hospital. Clear cut decision rules for this process applied to routine civilian emergency medical practice have yet to emerge.
