Alternative methods to central venous pressure for assessing volume status in critically ill patients. Journal of emergency nursing: JEN : official publication of the Emergency Department Nurses Association, 40(2), 115-23.More infoEarly goal-directed therapy increases survival in persons with sepsis but requires placement of a central line. We evaluate alternative methods to measuring central venous pressure (CVP) to assess volume status, including peripheral venous pressure (PVP) and stroke volume variation (SVV), which may facilitate nurse-driven resuscitation protocols.

Academic emergency medicine : official journal of the Society for Academic Emergency Medicine, 20(10), 997-1003.More infoHirsch's h-index (h) attempts to measure the combined academic impact and productivity of a scientist by counting the number of publications by an author, ranked in descending order by number of citations, until the paper number equals the number of citations. This approach provides a natural number or index of the number of publications and the number of citations per publication. H was first described in physics and was demonstrated to be highly predictive of continued academic activity, including recognized measures of scientific excellence such as membership in the National Academy of Sciences and being a Nobel laureate. Citation rates, research environments, and years of experience all affect h, making any comparisons appropriate only for scientists working in the same field for a similar time period. The authors are unaware of any report describing the distribution of h among academic emergency physicians (AEPs).

Analysis of automated external defibrillator device failures reported to the Food and Drug Administration. Annals of emergency medicine, 59(2), 103-11.More infoAutomated external defibrillators are essential for treatment of cardiac arrest by lay rescuers and must determine when to shock and if they are functioning correctly. We seek to characterize automated external defibrillator failures reported to the Food and Drug Administration (FDA) and whether battery failures are properly detected by automated external defibrillators.
- Cienki, J. J., Deluca, L. A., & Feaster, D. J. (2011). Course of untreated high blood pressure in the emergency department. The western journal of emergency medicine, 12(4), 421-5.More infoNo clear understanding exists about the course of a patient's blood pressure (BP) during an emergency department (ED) visit. Prior investigations have demonstrated that BP can be reduced by removing patients from treatment areas or by placing patients supine and observing them for several hours. However, modern EDs are chaotic and noisy places where patients and their families wait for long periods in an unfamiliar environment. We sought to determine the stability of repeated BP measurements in the ED environment.

Journal of biomedical optics, 16(10), 107004.More infoRetinal oximetry offers potential for noninvasive assessment of central venous oxyhemoglobin saturation (SO(2)) via the retinal vessels but requires a calibrated accuracy of ±3% saturation in order to be clinically useful. Prior oximeter designs have been hampered by poor saturation calibration accuracy. We demonstrate that the blue-green oximetry (BGO) technique can provide accuracy within ±3% in swine when multiply scattered light from blood within a retinal vessel is isolated. A noninvasive on-axis scanning retinal oximeter (ROx-3) is constructed that generates a multiwavelength image in the range required for BGO. A field stop in the detection pathway is used in conjunction with an anticonfocal bisecting wire to remove specular vessel reflections and isolate multiply backscattered light from the blood column within a retinal vessel. This design is tested on an enucleated swine eye vessel and a retinal vein in a human volunteer with retinal SO(2) measurements of ∼1 and ∼65%, respectively. These saturations, calculated using the calibration line from earlier work, are internally consistent with a standard error of the mean of ±2% SO(2). The absolute measures are well within the expected saturation range for the site (-1 and 63%). This is the first demonstration of noninvasive on-axis BGO retinal oximetry.

Journal of intensive care medicine, 26(3), 172-82.More infoRealizing the vast medical benefits of validated protocols, recommendations and practice guidelines requires acceptance and implementation by frontline care providers. Knowledge translation is the science of accelerating the transfer of knowledge to practice by understanding and creatively addressing the barriers that prevent adoption of new professional standards. In an attempt to improve patient care and reduce mortality, the Surviving Sepsis Campaign and The Institute for Healthcare Improvement created the resuscitation and management bundles for patients with severe sepsis and septic shock. These bundles have been accepted as best practice by many clinicians since multiple clinical trials have produced similar positive results when they were implemented. However, transferring these research outcomes-based guidelines to the clinical practice arena has been associated with poor compliance due to important barriers to implementation. Delays in the adoption of sepsis bundles are not surprising since the time from validation to implementation of a new clinical practice is typically 17 years. Using sepsis bundles as a model, this article explores why guidelines are important, examines physician adherence to protocols, and reviews the literature on strategies to improve clinical compliance and enhance knowledge translation.
- DeLuca, L. A., McEwen, M. M., & Keim, S. M. (2010). United States-Mexico border crossing: experiences and risk perceptions of undocumented male immigrants. Journal of immigrant and minority health / Center for Minority Public Health, 12(1), 113-23.More infoUndocumented immigrants crossing the US-Mexico border face many hazards as they attempt to enter the United States, including heat and cold injury, dehydration, and wild animal encounters. In the Tucson sector of the US-Mexico border, there are over 100 deaths a year from heat-related injuries alone. Public awareness campaigns have been undertaken to disseminate information on the dangers inherent in crossing. Little is known, however, about the ways in which undocumented immigrants actually receive information regarding the risks of crossing the border, how such information impacts their preparation for crossing or how the journey itself effects their motivation to cross again in the future. A qualitative descriptive method was used to describe and analyze information from adult males who had attempted to illegally cross the US-Mexico Border and had recently been returned to Mexico. Semi-structured interviews were conducted, and responses were classified into several broad themes. Interviews were conducted and analyzed iteratively until thematic saturation was achieved. The responses validated the established risks as being commonplace. A total of eight (8) male undocumented immigrants participated in the interviews. Individuals sought information prior to crossing from the media, their families and friends, and acquaintances in border towns. They did not appear to value any particular information source over any other. New areas of risk were identified, such as traveling with others who might have new or existing medical problems. There was also substantial concern for the family unit as both a source of inspiration and motivation. The family emerged as an additional at-risk unit due to the destabilization and financial strain of having one of its members leave to attempt to immigrate to the US for work. While many planned to cross again, the majority of the men in our sample had no intention of seeking permanent residence in the US, instead planning to work and then return to their families in Mexico. This preliminary study found that individuals crossing the US-Mexico border appear willing to put themselves and their families at substantial perceived risk in order to seek economic opportunity. Future public awareness campaigns may choose to shift focus solely from the individual risk of the crossing to the additional risks to family and community.

Journal of applied animal welfare science : JAAWS, 9(2), 129-41.More infoHuman volunteer blood donor programs are commonplace, but the concept of nonhuman animal blood banking is relatively new. Few studies exist regarding efficacy, donor screening, and safety for volunteer companion animals. This retrospective study evaluated a nonprofit, community-based canine volunteer donor program using community blood drives. Of 98 potential donors, 14 were ineligible to donate, including 4 who tested seropositive for blood-borne pathogens. Of 84 donors, 45 were Dog Erythrocyte Antigen (DEA) 1.1 positive and 39 were DEA1.1 negative. Donations totaling 143 included 29 repeat donors (35%). No serious adverse events occurred. Minor adverse events included acute donor reaction (2.8%), hematoma (4.2%), rebleeding (2.1%), and skin irritation (0.7%). Adverse event rates were comparable to data for human blood donations. A substantial fraction of donors donated multiple times, suggesting that volunteer donors and their guardians perceived the donation process to be safe and effective. This article discusses the issue of donor consent and use of the term volunteer. This study indicates that nonprofit, community-based canine volunteer donor programs for animal blood banks can be successful while maintaining high safety standards and ethical treatment of volunteers.

Academic emergency medicine : official journal of the Society for Academic Emergency Medicine, 11(3), 237-43.More infoAutomated blood pressure (ABP) devices are ubiquitous at emergency department (ED) triage. Previous studies failed to evaluate ABP devices against accepted reference standards or demonstrate triage readings as accurate reflections of blood pressure (BP). This study evaluated ED triage measurements made using an ABP device and assessed agreement between triage BP and BP taken under recommended conditions.
