Randomized Controlled TrialInfluence of orientations of guidewire tip on the placement of subclavian venous catheters.
The role of a J-type guidewire tip has been known to prevent vascular or cardiac wall damage. We hypothesized that the course of the guidewire may be influenced by the initial orientations of the J-type guidewire tip during the subclavian approach. The purpose of this study was to investigate the influence of the direction of the needle bevel and J-wire tip on successful placement of subclavian catheters. ⋯ These data suggest that the orientation of the J-wire tip downward can increase successful placement rates of right subclavian venous catheterization.

Improved survival after in-hospital cardiac arrest outside critical care areas.
The in-hospital Utstein Guidelines may be used to evaluate resuscitation strategies. This study utilized the Utstein template prospectively to examine changes in outcome and outcome-related factors after resuscitation outside critical care areas over a 10-year period. ⋯ Prospective Utstein style data collection proved to be a valuable tool for the evaluation of management and outcome following in-hospital cardiac arrest. Increased survival was seen over 10 years outside critical care areas. Organizational changes, including cardiopulmonary resuscitation training for ward personnel and standardized resuscitation management, may have contributed to this change.

Clinical TrialThe cuff method: a pilot study of a new method of monitoring neuromuscular function.
A new method of monitoring neuromuscular blockade based on a modified blood pressure cuff that incorporates stimulating electrodes was compared with mechanomyography (MMG) ('gold standard'). ⋯ This pilot study indicates that the cuff method could be useful to monitor neuromuscular blockade according to the bias and limits of agreement compared with MMG, particularly when the degree of blockade was evaluated by TOF ratios > 0.7. The new cuff method is easy and simple to use. However, further studies in a larger number of patients are necessary to confirm these favourable preliminary results.

Effect of pulmonary artery pressure on extravascular lung water in an experimental model of acute lung injury.
Lung edema can be influenced by hemodynamic changes in pulmonary circulation. The aim of this study was to evaluate, in an experimental model of acute lung injury, the effect on extravascular lung water (EVLW) of an increase in pulmonary artery pressure (Ppa) without changes in cardiac output and wedge pressure. ⋯ In this model, an increase in pulmonary artery pressure by alveolar hypoxia produces an increase in extravascular lung water, probably related to changes in pulmonary capillary pressures.
