Randomized Controlled Trial
Precise minute ventilation delivery using a bag-valve mask and audible feedback.
The efficacy of a modified bag-valve mask (BVM) with a ventilation rate alarm system was compared with conventional BVM to maximize adequate minute ventilation volume delivery in a manikin model. ⋯ In a manikin arrest model, the use of RVBVM results in a more constant and regular minute tidal ventilation rate than the use of VBVM and is, therefore, expected to produce more favorable outcomes in practical resuscitative situations.

Little is known about emergency department (ED) quality of care for joint dislocation. We sought to determine concordance of ED management of dislocation with guideline recommendations and to assess whether higher concordance was associated with better patient outcomes. ⋯ Concordance of ED management of joint dislocation with guideline recommendations was high. Greater concordance with guideline-recommended care may increase the likelihood of successful joint reduction.

Traumatic dissection of the aorta is a well-documented entity with poor prognosis and broad spectrum of clinical presentations. We report a rare case of an asymptomatic late presentation of aortic dissection after a high-speed vehicle accident. This case highlights the importance of high clinical suspicion for the diagnosis of aortic dissection.

Lactic acidosis is a marker of tissue hypoperfusion and impairs oxygen delivery. High lactate levels are associated with altered systemic hemodynamics, tissue hypoperfusion, and altered cellular metabolism. Increased lactate levels have also been reported as a complication of β-adrenergic agents administered during asthma therapy. ⋯ Previous studies have suggested that administration of β agonists can lead to lactic acidemia in the absence of hypoxia or shock, but it is the highest level of lactate that we found in the literature. In sepsis and shock, lactic acidosis is used as a marker of disease severity. In this case, it is not necessarily the sign of an immediate gravity.

Hospitals implement electronic medical record systems (EMRSs) that are intended to support medical and nursing staff in their daily work. Evolution toward more computerization seems inescapable. Nevertheless, this evolution introduced new problems of organization. ⋯ In the satisfaction questionnaire, clinicians reported minimal satisfaction but refused to return to handwritten records. The increase in door-to-FMC time may be explained by the improved quantity/quality of data and by the many interruptions due to the software. Medical reorganization was requested after the installation of the EMRS.
