The Gulf War: The Experience of a Department of Anesthesiology in the Management of Scud Missile Casualties
Authors: Adu-Gyamfi Yaw 
Published: July 2016

AbstractBackground:The pivotal role of anesthesiologists in the implementation of disaster plans is not widely appreciated.Objective:To describe the role of anesthesiologists as managers in the operating room (OR) especially during hospital disaster management.Methods:On 25 February 1991, King Fahd Hospital of the University in Eastern Saudi Arabia, was alerted, received, triaged, and treated the victims of a Scud missile attack on a United States military barracks which killed 28 and injured more than 100 service personnel.Results:There were 47 males and 15 females admitted to the hospital. Their initial triage categories of injuries were: 1) red, 23; 2) yellow, 27; and 3) green, 7. The flow of patients through the main operating rooms occurred in two peaks: 1) treated within nine hours (60%); and 2) during the next 11 hours (40%). A total 101 units of blood and blood products were consumed.The role of the Chief of Anesthesiology was vital in the dynamics of the situation regarding appropriate deployment of staff and ensuring an orderly throughput of victims in the operating room. He also was required to keep track of resources and supply levels in the operating room, so that he could advise the hospital administration appropriately.Conclusion:The successful management of a large multi-casualty incident, which involved use of the operating rooms, depended upon the efficient coordination of clearly defined functions with the Chief of Anesthesiology Service as the team leader.

Published: July 2016

AbstractIntroduction:Rock and contemporary music concerts are popular, recurrent events requiring on-site medical staffing.Study objective:To describe a novel severity score used to stratify the level of acuity of patients presenting to first-aid stations at these events.Methods:Retrospective review of charts generated at the first-aid stations of five major rock concerts within a 60,000 spectator capacity, outdoor, professional sports stadium. Participants included all concert patrons presenting to the stadiums first-aid stations as patients. Data were collected on patient demographics, history of drug or ethanol usage while at the concert event, first-aid station time, treatment rendered, diagnosis, and disposition. All patients evaluated were retrospectively assigned a “DRUG-ROCK” Injury Severity Score (DRISS) to stratify their level of acuity. Individual concert events and patient dispositions were compared statistically using chi-square, Fisher's exact, and the ANOVA Mean tests.Results:Approximately 250,000 spectators attended the five concert events. First-aid stations evaluated 308 patients (utilization rate of 1.2 per 1,000 patrons). The most common diagnosis was minor trauma (130; 42%), followed in frequency by ethanol/illicit drug intoxication (98; 32%). The average time in the first-aid station was 23.5±22.5 minutes (± standard deviation; range: 5–150 minutes). Disposition of patients included 100 (32.5%) who were treated and released; 98 (32%) were transported by paramedics to emergency departments (EDs); and 110 (35.5%) signed-out against medical advise (AMA), refusing transport. The mean DRISS was 4.1 (±2.65). Two-thirds (67%) of the study population were ranked as mild by DRISS criteria (score = 1–4), with 27% rated as moderate (score = 5–9), and 6% severe (score >10). The average of severity scores was highest (6.5) for patients transported to hospitals, and statistically different from the scores of the average of the treated and released and AMA groups (p <0.005).Conclusion:The DRISS was useful in stratifying the acuity level of this patient population. This severity score may serve as a potential triage mechanism for future mass gatherings such as rock concerts.
Quality Management Tool for Mass Casualty Emergency Responses and Disasters
Authors: Villarreal Marcus S. 
Published: July 2016

AbstractIntroduction and background:Quality management (QM) principles generally have not been applied to multi-casualty and disaster situations. Quality management incorporates quality assurance (QA) and quality improvement (QI) supported by a management information system (MIS). Since responders to disasters and multi-casualty incidents generally operate on standing orders and/or protocols, the character of the responses lends itself to quality management methods. Standards and indicators of performance readily can be developed for these situations.Objectives:1) to format disaster medical records as data collection instruments; 2) to develop appropriate tools that are easy to use for rapid assessments; 3) to develop a mechanism for determination of causes of injuries; and 4) to develop methods to: a) track patients; b) document response and recovery; andc) document the circumstances associated with the event.Methods:Model tools using checklists and short, fill-in answers are provided. These tools are designed to be incorporated into the trauma or EMS registries. Emergency medical technicians, nurses, physicians, and medical students scored the same disaster scenario for the functional areas of calling the state of the disaster, triage, and field stabilization.Results:Testing indicated that the checklists are completed in less than one minute, and produce objective data per patient in each functional area evaluated. In one instance, data were compiled for 38 patients from one bus accident in less than 10 minutes. The same data were reproduced, without variation, in the same amount of time, by three different providers of varied professional backgrounds.
Survey of Iowa Emergency Medical Services on the Effects of the 1993 Floods
Authors: Chartoff Stanley E. , Gren Joann M. 
Published: July 2016

AbstractIntroduction:From June through August 1993, extensive flooding in the Mississippi and Missouri River basins resulted in 50 deaths and 12 billion dollars [U.S.] in damages in nine Midwestern states. In Iowa (1990 population 2,777,000), the government declared all 99 counties Federal Disaster Areas. This study examines how this event impacted local emergency medical services (EMS).Methods:All 797 registered prehospital ambulance, rescue, and first-response companies in Iowa received survey questionnaires. Two follow-up mailings were provided for non-responders.Results:A total of 468 EMS companies (59%) returned completed questionnaires. The geographic distribution ofresponders and non-responders was similar. Of the companies responding, 132 (28%) reported an impact on their operations from the flood disaster. The most frequently reported operational changes included the use of non-traditional vehicles, providing aid to regions outside usual service areas, and involvement in non-medical rescue operations.Conclusion:A major flood provides unique challenges for emergency medical services. Cross-sectional surveys can identify areas of improvement for prehospital systems located in flood-prone areas. Results from this study provide a basis for constructing a more refined instrument to study future flood disasters.
Adenosine for the Treatment of PSVT in the Prehospital Arena: Efficacy of an Initial 6 mg Dosing Regimen
Authors: Wittwer Lynn K. , Muhr Marc D. 
Published: July 2016

AbstractObjective:To confirm the efficacy of pre-hospital administration of adenosine, using a 6 milligram (mg) initial dosing regimen, for the treatment of paroxysmal supraventricular tachycardia (PSVT).Methods:Urban, suburban, rural emergency medical services (EMS) system in Clark County, Washington with advanced life support (ALS) patient transports. Concurrent, paramedic Medical Incident Report (MIR) review was conducted for 102 patients receiving prehospital adenosine during a 42-month period. Patients were administered 6 mg of adenosine using an intravenous (IV) bolus followed by 10 ml of balanced salt solution flush. If the patient's rhythm remained unchanged, the dosing regimen was increased to 12 mg followed by a 10 ml flush. This was repeated once more if the rhythm remained unchanged, to a total maximum dose of 30 mg. Medical direction for administration of adenosine was in the form of standing orders rather than direct (on-line) medical control.Results:Seventy-four of 102 patients had PSVT as determined by physician analysis of the initial six-second electrocardiographic rhythm strip (ECG) recording. Sixty-six of these patients converted their cardiac rhythm from PSVT using adenosine; 46 (70%) converted with the initial 6 mg bolus. Fifteen patients converted after receiving the second dose (12 mg); and five patients required 30 mg.Conclusion:These results show that for paramedics, adenosine is an effective treatment for PSVT. An initial bolus of 6 mg converts the majority of cases. Eighty-nine percent of cases of confirmed PSVT converted with adenosine administration.

Published: July 2016

AbstractIntroduction:The pressures facing emergency medical services (EMS) in Wisconsin and their effects on the delivery of prehospital emergency medical care were not known by the Wisconsin EMS Board. In an effort to assess these pressures and the needs of the emergency medical services in the State as perceived by the services, the Board undertook a survey of the EMS providers in Wisconsin.Methods:A survey instrument was developed and approved by the EMS Board and distributed to all of the licensed emergency medical services in Wisconsin.Results:Of the 453 survey instruments distributed, 323 (71.3%) were completed and returned. Intermediate- and paramedic-level services were more likely to respond than were the basic services, but 235 (72.8%) of the respondents identified their service levels as basic. In addition to providing information about the service characteristics, each responding service also rated the importance of their perceived needs. Lack of medical direction was perceived as the greatest need by all levels of service. However, the second greatest area of need for basic and intermediate services related to difficulty in recruiting new staff. For paramedic services, the second greastest need was associated with dispatching. When comparing services by rural versus urban, difficulty in recruiting new staff and collecting ambulance fees were seen as second and third to lack of a medical director by rural services, whereas urban services noted local training to be in the top three. In the assessment of educational needs, patient-care issues dominated. A review of written comments also demonstrated a difference between rural and urban services, but both noted Medicare and Medicaid reimbursement issues more commonly than any other problem.Conclusion:In the restructuring of health care, it will be important to consider the various needs of prehospital providers and recognize that such needs may be unique to the providers' location and level of service.
Patients Who Refuse Transportation by Ambulance: A Case Series
Authors: Hipskind John E. , Gren JM , Barr DJ 
Published: July 2016

AbstractIntroduction:Patients refusing hospital transportation occurs in 5% to 25% of out-of-hospital calls. Little is known about these calls. This study was needed to determine the demographics, inherent risks, and timing of refused calls.Methods:This was a prospective review of all run sheets of patients who refused transportation were collected for a two month period. Demographic data and medical information was collected. Each run was placed into one of three categories of need for transport and further evaluation: 1) minimal; 2) moderate; and 3) definite. The Greater Elgin Area Mobile Intensive Care Program (GEA-MICP) based at Sherman Hospital in Elgin, Illinois, was the setting. The GEA-MICP is an Emergency Medical Services (EMS) system comprised of 17 advanced life support (ALS) ambulance agencies servicing northeastern Illinois. Study subjects were all patients who refused transportation to a hospital by ALS ambulance during July 1993 and February 1994. Paramedics were required to complete a run sheet for all calls.Results:Overall, 30% (683 of2,270) of all runs resulted in refusal of transportation. Patients who most commonly refused transportation were asymptomatic, 11–40 years old and involved in a motor vehicle crash. They usually had no past medical history, normal vital signs, and a normal mental status. Patients generally signed for their own release after evaluation. The average time to arrival was 4.2 minutes and average time spent on scene by paramedics was 18.4 minutes. Of the patients, 72% were judged to have minimal need, 25% were felt to have a moderate need, and 3% were felt to definitely need transport to a hospital for further evaluation and/or treatment.Conclusion:There are many cases when EMS are activated, but transportation is refused. Most refusals occur after paramedic evaluation. Providing paramedics with primary care training and protocols would standardize care given to patients and provide a mechanism for discharge instructions and follow-up for those who chose not to be transported to a hospital. Patients judged to require further treatment had unique characteristics. These data may be useful in identifying potentially sicker patients allowing a concentrated effort to transport this subset of patients to a hospital.
Medical Anti-Shock Trousers: Pneumatic Anti-Shock Garment: Does it Work?
Authors: McSwain Norman E. 
Published: July 2016

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.

Published: July 2016

AbstractThe use of bronch odilators in the prehospital EMS setting is common. This study examined the safety of the administration of 2.5 mg albuterol using a hand-held nebulizer for the treatment of such patients.A total of 55 patients were included. Following treatment, peak expiratory flow rates (PEFR) increased a mean of 27 L/min, ventilatory rate decreased four breaths/min, heart rate decreased slightly, and systolic blood pressure increased 10 mmHg. Five of the 53 patients in whom cardiac rhythm was monitored, had premature ventricular complexes prior to treatment; only one did following therapy. Breath sounds improved in 61% and were unchanged in 39%. Breathing was reported by the patient as improved in 51 of the 53 (93%) and only one felt worse. Adverse reactions were reported in 15%, but none were severe. This study shows that albuterol (2.5 mg) administration by hand-held nebulizer is both safe and efficacious in the prehospital setting.

Published: July 2016

AbstractIntroduction:Pediatric Emergency Air Transports (PEATs) at Massachusetts General Hospital, Boston, Massachusetts, were reviewed between November 1986 and December 1987. Severity of illness, complications, and outcome of PEATs were compared with ground transports. Factors associated with PEAT survival were identified.Methods:Severity of illness was measured using a modified Denver Patient Status Category (DPSC) method and the Therapeutic Intervention Scoring System (TISS). There were 35 PEATs (30 helicopter, five fixed-wing) and 96 ground transports.Results:Mean severity of illness for patients was greater in PEAT than for the ground transport (PEAT DPSC score=4.23±1.06 versus ground DPSC=3.57±0.89 [SD], p=.0005). The PEAT mortality was associated with a greater mean severity of illness (TISS survivors=19.1±11.4 versus non-survivors=44.3±9.5, p=.0001), but not with: the presence of an in-flight physician; transport delay; transport duration; age; sex; history of chronic illness; or intra-transport medical complication.Conclusions:Compared to ground transports, PEATs were used for higher risk patients.
Gas-Powered and Portable Ventilators: An Evaluation of Six Models
Authors: Nolan Jerry P. , Baskett Peter J.F. 
Published: July 2016

AbstractIntroduction:Gas-powered resuscitators (ventilators) designed to be used primarily for resuscitation should be basic and simple to use. They offer many advantages over manual methods of ventilation during in-hospital cardiopulmonary resuscitation. Portable ventilators intended for critical care transport require additional, more sophisticated features such as: adjustable pressure limiting valves, air-mixing, airway pressure gauge, independent tidal volume and rate controls, and a Positive End-Expiratory Pressure (PEEP) valve. The performance of six gas-powered resuscitators/portable ventilators (TransPAC, Oxylog, Ambu Matic, ERA 2000, Uni-Vent, and MARS) was evaluated.Methods:The accuracy of volumes delivered to a test lung at three different compliance and resistance settings, was assessed for each ventilator prior to clinical evaluation during cardio-pulmonary resuscitation (CPR) and patient transport.Results:In each circumstance, measured tidal volumes and levels of minute ventilation decreased as resistance was increased and compliance reduced. Much of this loss of measured tidal volume occurred through inspiratory pressure relief valves that tended to start leaking at pressures below the preset level. Increasing levels of back-pressure resulted in further reductions in tidal volume when the ventilators were tested using the air-mix mode (available on three of the devices). In general, each resuscitator functioned well when used during CPR within the hospital.Conclusions:Each resuscitator tested failed to deliver the preset volumes and this must be considered during their use. Inspiratory pressure relief valves for all but one of the ventilators tested would not permit the delivery of adequate levels of ventilation in patients with low pulmonary compliance and/or high airway resistance.
Emergency Medical Services Systems Issues: A Delphi Study
Authors: Chin Jonathan , Schario Mark E. 
Published: July 2016

AbstractA Delphi survey was conducted to determine the current and future issues facing emergency medical services systems. The information provided by this study can be used by individuals involved in emergency medical services systems for strategic planning and evaluation. The issues identified are categorized and listed by priority. A tiered priority model is utilized to represent the interrelations between these issues. Economics, leadership, research, and human resources are the foremost issues identified in this study. Further detailed analysis and refinement of these issues is recommended for local application. Emergency medical services systems need information to drive the decision-making process.

Published: July 2016

AbstractIntroduction:Airway management is the most critical and potentially life-saving intervention performed by emergency medical service (EMS) providers. Invasive airway management often is required in non-cardiac-arrest patients who are combative or otherwise uncooperative. The success of prehospital invasive airway management in this patient population was evaluated.Methods:A retrospective review was undertaken of the records of all such patients requiring endotracheal intubation over a three-year period (1987–1989). The study population included 278 patients enrolled by five advanced life support (ALS) units serving a suburban population of 425,000. Field trip sheets were reviewed for diagnosis, intubation method and success, number of intubation attempts, provider experience, reasons for unsuccessful intubations, and complications.Results:A total of 394 invasive airway management attempts were performed on 278 patients. The overall successful intubation rate was 75% (41 % orotracheal, 52% nasotracheal, 7% other or unknown). The most common diagnoses were COPD and pulmonary edema (30%) and trauma (24%). Experienced providers were successful on the first attempt in 57% of cases compared to 50% by inexperienced providers (p=.24). Multiple intubation attempts were required in 33% of the patients. There was no statistically significant difference in success rates between the orotracheal and nasotracheal methods (p=.51). The most common reason for unsuccessful intubation was altered level of consciousness. Complications occurred with 7% of successful attempts and in 18% of unsuccessful attempts (p<.001). Forty-six percent of the patients who were not intubated successfully in the field and required intubation in the emergency department (ED) received a neuromuscular blocking agent prior to successful intubation.Conclusion:Prehospital providers can intubate a high but improvable proportion of non-cardiac-arrested patients by both the orotracheal and nasotracheal routes. The use of pharmacologic adjuncts to facilitate the prehospital intubation of selected, non-cardiac-arrested patients is a promising adjunct that needs further evaluation.
The Outcome of Patients Refusing Prehospital Transportation

Published: July 2016

AbstractObjective:To study the natural outcome of patients refusing prehospital transportation (PT).Methods:A total of 188 consecutive patients who refused PT in an urban, advanced life support (ALS), emergency medical services (EMS) system were studied. Of these, 77 (41 %) were male, and the average age was 51 years. Patients were entered into the study group only once.Results:Only 94 (50%) patients could be reached by telephone follow-up. Seven (7%) of these 94 patients had abnormal vital signs, 33 (35%) had cardiopulmonary complaints, 16 (17%) had an altered level of consciousness, nine (10%) were involved in accidents, and eight (8%) had abdominal pain. Six (6%) patients were admitted to the hospital, two (2 %) received ALS-level treatment by the paramedics and then refused conveyance, and 31 (33 %) either saw or contacted a physician. Consultation with an EMS physician was initiated for nine (5%) refusals. Of all the patients contacted, six (6%) needed PT for hospitalization.Conclusion:As only 50% of the patients refusing prehospital transportation could be reached using follow-up telephone calls, the 6% figure probably underestimates the true number of patients requiring PT. Telephone follow-up is an inadequate means of determining the natural outcome for this patient population. The ALS nature of many of the complaints combined with the lack of consistent physician consultation, exposes the EMS system to an undefined medico-legal liability risk.
