Protocol-based noninvasive positive pressure ventilation for acute respiratory failure.
Noninvasive positive pressure ventilation (NPPV) has been suggested to be associated with adverse outcomes in emergency patients with acute respiratory failure (ARF), possibly because of a delay in tracheal intubation (TI). We hypothesized that protocol-based NPPV (pNPPV) might improve the outcomes, compared with individual physician-directed NPPV (iNPPV). ⋯ The present study suggests that pNPPV is effective and likely to improve the mortality rate of emergency patients with ARF.

Awareness during anesthesia: the results of a questionnaire survey in Japan.
We planned a survey to evaluate the current incidence and risk factors of intraoperative awareness. ⋯ The most surprising finding of this study is that total intravenous anesthesia (TIVA) was used in 21 of the 24 (88%) cases of definite and possible awareness. Although the incidence of intraoperative awareness was compatible with the previous studies, meticulous care should be taken when anesthesia is performed by TIVA for high-risk patients. The results of this survey should be verified, as well as further continuous survey and prospective study, because this study was performed by an anonymous questionnaire survey conducted over only 1-year period.
