Comparative Study
Multiple resuscitation regimens in a near-fatal porcine aortic injury hemorrhage model.
To compare early and delayed blood administrations in animals subjected to near-fatal hemorrhage in the presence of a vascular injury and resuscitated to different mean arterial pressures (MAPs). ⋯ In this model of near-fatal hemorrhage with a vascular injury, maintenance of the hypotensive state produced comparable improvements in one-hour survival and reductions in hemorrhage volume regardless of whether blood or saline was administered first. Although hypotensive resuscitation resulted in improved outcome, it was associated with significant acidosis. This effect was minimized with moderate rather than severe underresuscitation and early blood administration.

To determine the occurrence of weapon carriage by major trauma patients at a university/county hospital ED. ⋯ ED major trauma patients at one urban trauma center in Los Angeles frequently carry weapons, including automatic military weapons. In addition to violence prevention measures such as weapon confiscation, plans must be made and practiced for the management of violence within the "sacrosanct" hospital doors to protect both patients and ED personnel.

Randomized Controlled Trial Comparative Study Clinical Trial
Prospective evaluation of topical antibiotics for preventing infections in uncomplicated soft-tissue wounds repaired in the ED.
To determine differences in infection rates among uncomplicated, repaired wounds managed with: topical bacitracin zinc (BAC); neomycin sulfate, bacitracin zinc, and polymyxin B sulfate combination (NEO); silver sulfadiazine (SIL); and petrolatum (PTR). ⋯ The use of topical antibiotics resulted in significantly lower infection rates than did the use of a petrolatum control. BAC and NEO had the lowest wound infection rates.

To report cardiac arrest demographics and assess whether arrest rate is associated with differences in intracity regional population densities, incomes, or race distributions. ⋯ The association of lower income with cardiac arrest suggests that cardiac health promotion and EMS intervention measures, including CPR instruction, should be targeted to lower-income neighborhoods. These findings may help explain previous studies suggesting a racial or population density association with cardiac arrest rates.

To determine whether a certain distance measurement on the oral endotracheal tube (ETT) at the corner of the mouth could reasonably ensure proper depth of placement in critically ill patients, without the immediate need for a confirming chest x-ray (CXR). ⋯ Proper depth of ETT placement in the critically ill adult patient can be estimated by the technique of this study. In this adult patient population, corner-of-the-mouth placement of the ETT using the 21-cm tube mark for the women and the 23-cm mark for the men would have led to proper placement for most patients.
