There has been much federal and local health planning for an influenza pandemic in the United States, but little is known about the ability of the clinical community to deal quickly and effectively with a potentially overwhelming surge of pandemic influenza patients.

The attitudes and expectations of emergency physicians, emergency nurses, hospital nursing supervisors, hospital administrators, and infection control personnel concerning clinical care in a pandemic were assessed.

Key informant structured interviews of 46 respondents from 34 randomly selected emergency receiving hospitals in Los Angeles County were conducted using an Institutional Review Board-approved protocol. The interview asked about supplies/resources, triage, quality of care, and decision-making. At the conclusion of each interview, the informant was asked to provide the contact information for at least two others within their respective professional group. Interviews were transcribed and coded for key themes using qualitative analytical software.

There was little salience that an influx of variably ill patients with influenza would force stratified healthcare decision-making. There also was a general lack of preparation to address the ethics and practices of triaging patients in the clinical setting of a pandemic.

Guidelines must be developed in concert with public health, medical society, and legislative authorities to help clinicians define, adopt, and communicate to the public those practice standards that will be followed in a mass population, infectious disease emergency.

This study examines those factors predictive of self-perceived first-aid abilities among a community-based sample after the 1994 Northridge earthquake.

A probabilities-proportionate to-size (pps) sample of residents of Los Angeles County and 11 pre-selected zip codes from southeastern Ventura County was selected using computer-generated random digit-dialing (rdd) procedures 7–11 months after the earthquake. Data were collected from 506 individuals in 45 minute interviews. A unidimensional scale of self-perceived first-aid ability was created and represents the dependent variable in a causal path model.

In a causal path model, standardized path coefficients suggested that while reports of taking first-aid courses were the most influential factors in predicting higher self-perceived first-aid abilities, other factors including being white, younger, speaking English in the home, and lower income also predicted higher self-perceived first-aid abilities that were independent from taking formal first-aid courses.

First-aid training should be directed towards target segments of the population that are not likely to have had instruction in these basic skills. Those individuals who self-report high first-aid proficiency, independent of formal first-aid training, should be evaluated to assess their abilities to perform these skills.

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).

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.

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.

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.

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).

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.

Although major sequelae of carbon-monoxide (CO) poisoning and its treatment with hyperbaric oxygen (HBO) are well-documented, a syndrome of low-level CO poisoning has received relatively little attention. Subtle symptoms of poor concentration, language difficulty, problems with calculations, and memory loss were noted after an acute exposure of 131 dormitory residents to low levels of CO. The CO Neuropsychological Screening Battery (CONSB), a series of tests reported by others as useful to identify victims of CO poisoning, was performed on a subset of 46 victims. It was hypothesized that their test scores would improve after treatment with HBO.

Testing was performed both before and after HBO on 35 CO-exposed victims. A control group of 20 students residing on the same college campus, but not involved with the CO incident, also were tested on two separate occasions to assess the ability of the test to identify selectively victims of low-level CO poisoning, as well as to evaluate its validity when administered serially.

Both CO-exposed and control subjects demonstrated significant performance improvement when completing the testing for the second time. In addition, the baseline test scores were not significantly different for either the CO-exposed or the control groups. Nonetheless, all CO-exposed victims reported immediate subjective improvement of their symptoms after HBO therapy.

These observations and a review of the literature suggest that there might exist a syndrome of subtle neurological disturbances in victims of low-level CO poisoning. Whether this is permanent or might regress spontaneously over time is unknown. As a diagnostic adjunct, the CONSB does not appear to be as useful in low-level CO poisoning.
