Comparative Study Clinical Trial
Ultrasound validation of maneuvers to increase internal jugular vein cross-sectional area and decrease compressibility.
The aim of this study is to determine which maneuvers result in greatest cross-sectional area (CSA) of the internal jugular vein (IJV) and reduce collapsibility as measured by ultrasound during simulated venipuncture. ⋯ All maneuvers with the exception of hepatic pressure led to a statistically significant increase in IJV CSA as compared with baseline with and without simulated venipuncture. Valsalva was the only maneuver, when used alone or in combination, to increase the CSA by greater than 50% and prevent collapse by 50% or more under simulated venipuncture.

Comparative Study Clinical Trial
Evaluation of lung ultrasound for the diagnosis of pneumonia in the ED.
The aim of this study is to assess the ability of bedside lung ultrasound (US) to confirm clinical suspicion of pneumonia and the feasibility of its integration in common emergency department (ED) clinical practice. ⋯ Considering that lung US is a bedside, reliable, rapid, and noninvasive technique, these results suggest it could have a significant role in the diagnostic workup of pneumonia in the ED, even if no sensitivity nor specificity can be inferred from this study because the real gold standard is CT, which could not be performed in all patients.

The purpose of the study is to investigate the influence of cardiopulmonary resuscitation (CPR) time before the first defibrillation. ⋯ In patients with out-of-hospital-witnessed VF, sufficient CPR before the first defibrillation is considered to improve the neurologic outcome in comparison to the performance of immediate defibrillation.

Comparative Study
Head and neck cooling after cardiac arrest results in lower jugular bulb than esophageal temperature.
To determine whether during the initial phase of head and neck cooling, jugular bulb temperature (Tjb; which may reflect brain temperature) is lower than esophageal temperature (Tes). ⋯ During the initial phase of therapeutic hypothermia, Tjb seems to be lower than Tes.

Comparative Study
Comparison of initial antibiotic choice and treatment of cellulitis in the pre- and post-community-acquired methicillin-resistant Staphylococcus aureus eras.
Treatment success of cellulitis in the age of community-acquired methicillin-resistant Staphylococcus aureus (CAMRSA). A comparison of initial antibiotic choice and treatment success in the pre- and post-CAMRSA eras. ⋯ Our study demonstrates that prescribing practices for simple cellulitis have changed since the emergence of CAMRSA. This may not be appropriate because beta-lactam antibiotics perform as well as 'CAMRSA antibiotics' in our study.
