Multicenter Study
A prospective multicenter evaluation of prehospital airway management performance in a large metropolitan region.
To determine 1) the success rate of prehospital endotracheal intubation; 2) the unrecognized tube malposition rate; and 3) predictors of tube malposition upon arrival to the emergency department (ED) in the setting of a large metropolitan area that includes 18 hospitals and 34 transporting emergency medical services (EMS) agencies. ⋯ Overall intubation success was low, and consistent with previously published series. The frequency of malpositioned ETT was unacceptably high, and also consistent with prior studies. Our data support the need for ongoing monitoring of EMS providers' practices of endotracheal intubation.

Comparative Study
Field torso-warming modalities: a comparative study using a human model.
To compare four field-appropriate torso-warming modalities that do not require alternating-current (AC) electrical power, using a human model of nonshivering hypothermia. ⋯ In subjects with shivering suppressed, greater sources of external heat were effective in attenuating core temperature afterdrop, whereas sustained sources of external heat effectively established core rewarming. Depending on the scenario and available resources, we recommend the use of charcoal heaters, chemical heating pads, or hot-water bags as effective means for treating cold patients in the field or during transport to definitive care.

Activated charcoal (AC) is a potentially beneficial intervention for some toxic ingestions. When administered within one hour, it can reduce absorption of toxins by up to 75%. This study evaluated whether pediatric emergency department (ED) patients arriving by ambulance receive AC more quickly than patients arriving by alternative modes of transport. ⋯ The sickest patients arriving by EMS had a faster time from triage to AC administration. However, when comparing patients of all triage categories, EMS arrival alone did not influence time to AC administration. Furthermore, the interval from triage to charcoal administration was often insufficiently long. This suboptimal timing of charcoal administration demonstrates the need for reevaluation of triage and prehospital practices.

To describe the preliminary experience of an emergency medical services (EMS)-based follow-up program providing elderly patients access to community-based social services. ⋯ EMS provides an invaluable opportunity to connect the elderly with social services at the time of contact. In this study, paramedics appeared to refer more social service-related complaints compared with other categories such as fall assistance. This highlights a difference in perception of social service needs among paramedics and represents an area for further training and education.

Little is known about mechanical ventilation practices during patient transport outside of hospital in the civilian setting, although these practices may have clinical impact. Objective. We set out to describe ventilation practice, the use of lung-protective ventilation strategies, administration of sedation and neuromuscular blockade, and related critical events during out-of-hospital transport of ventilated patients. ⋯ In-transit mechanical ventilation practices are variable, although patient exposure to potentially injurious pressures and volumes is uncommon. The application of PEEP is modest. In-transit hypotension is common and associated with sedative administration. The extent to which these practices impact patient outcome is unclear.
