Attitudes toward automated external defibrillator use in Japan in 2011.
Early use of an automated external defibrillator (AED) improves the chances of successful resuscitation and survival. We have surveyed Japanese individuals on their attitude towards using an AED if they witnessed a cardiac arrest and compared the results with those of our previous study in 2006. ⋯ The number of Japanese individuals who are familiar with the concept of AEDs and who are also willing to use these devices was considerably higher in the current study than in the 2006 study. However, more Japanese individuals should be made aware of AEDs and become familiar with their use.

Learning curve of medical students in ultrasound-guided simulated nerve block.
Good hand-eye coordination is a prerequisite for safe ultrasound-guided peripheral nerve blocks. However, new skills have to be acquired when compared to the traditional nerve stimulation technique. We tested and mathematically described the learning curve of these skills in inexperienced ultrasound users employing a simple phantom of a peripheral nerve. ⋯ Based on our mathematical analyses of the learning curve, inexperienced ultrasound users can improve their hand-eye coordination within 5 subsequent trials in a simple model of a peripheral nerve block.

Clinical TrialPerfusion index as a possible predictor for postanesthetic shivering.
Postanesthetic shivering can be triggered by surgical stress and several aspects of anesthetic management and is frequently preceded by a decrease in peripheral blood flow due to thermoregulatory vasoconstriction. As perfusion index correlates with peripheral blood flow, we examined whether perioperative perfusion index, measured using pulse oximetry, might be correlated with postanesthetic shivering. ⋯ Perfusion index was significantly lower in patients with postanesthetic shivering before emergence from anesthesia, indicating that measurement of perfusion index during and before the end of anesthesia might be a useful means of predicting postanesthetic shivering.
