The impact of body mass index on the physiology of patients with polytrauma.
Obesity is a growing problem in industrial nations. The aim was to test the hypothesis that overweight patients face early physiologic impairment. ⋯ Anticipating BMI-specific critical trauma problems will become mandatory for effective polytrauma treatment in industrialized nations given their increasing prevalence of obesity.

Prediction of extubation failure in medical intensive care unit patients.
The purpose of this study was to evaluate prediction factors for extubation failure (need for reintubation within 48 hours) in medical intensive care unit patients. ⋯ Low preextubation serum anion gap values and low preextubation Pao(2)/Fio(2) ratio might help to predict extubation failure in medical intensive care unit patients.

Assessing the national productivity in subspecialty critical care medicine journals: a bibliometric analysis.
In recent years, significant growth has been seen in the subspecialty critical care medicine. However, the national productivity to the subspecialty critical care medicine remains unknown. We therefore intended to reveal the national contribution in the subspecialty critical care medicine journals. ⋯ The United States is the most productive country in the subspecialty critical care medicine. When normalized to population size, Australia and some European countries might be more productive.

Clinical TrialA new parameter for the diagnosis of hemorrhagic shock: jugular index.
The purpose of this study is to investigate whether there are any significant changes in the diameter and the area of the internal jugular vein (IJV) during the hemorrhagic shock. ⋯ We believe that measurement of the IJV and the jugular index is a reliable indicator of class 1 hemorrhagic shock. It may be used as a part of focused abdominal sonography for trauma in clinical practice.

Randomized Controlled TrialTopical nitroglycerin and lidocaine locally vasodilate the radial artery without affecting systemic blood pressure: a dose-finding phase I study.
Small radial artery diameter (RAD) and vasospasm are barriers to radial artery cannulation. We performed this study to determine if topical nitroglycerin and/or nitroglycerin plus topical lidocaine increases RAD without affecting systemic blood pressure. ⋯ Topical nitroglycerin and lidocaine significantly increase RAD within 30 to 60 minutes with no effect on contralateral radial artery or blood pressure, indicating a direct, local effect on the radial artery. (Clinicaltrials.gov number NCT00686231).
