Randomized Controlled TrialThe Effect of High-Flow Nasal Oxygen on Carbon Dioxide Accumulation in Apneic or Spontaneously Breathing Adults During Airway Surgery: A Randomized-Controlled Trial.
Significant CO2 accumulation occurs during apneic oxygenation with high-flow nasal oxygen, potentially limiting safety during prolonged apnea.

Competence in Decision Making: Setting Performance Standards for Critical Care.
Health care professionals must be able to make frequent and timely decisions that can alter the illness trajectory of intensive care patients. A competence standard for this ability is difficult to establish yet assuring practitioners can make appropriate judgments is an important step in advancing patient safety. We hypothesized that simulation can be used effectively to assess decision-making competence. To test our hypothesis, we used a "standard-setting" method to derive cut scores (standards) for 16 simulated ICU scenarios targeted at decision-making skills and applied them to a cohort of critical care trainees. ⋯ Minimum competence standards for high-stakes decision making can be established through standard-setting techniques. We effectively identified "front-line" providers who are, or are not, ready to make independent decisions in an ICU setting. Our approach may be used to assure stakeholders that clinicians are competent to make appropriate judgments. Further work is needed to determine whether our approach is effective in simulation-based assessments in other domains.

Association Between Preoperative Statin Use and Respiratory Complications After Noncardiac Surgery: A Retrospective Cohort Analysis.
Statins possess pleiotropic effects, which potentially benefit noncardiovascular conditions. Previous work suggests that statins reduce inflammation and prevent acute respiratory distress syndrome and infections. However, there is a paucity of data regarding potential benefits of statins on respiratory and infectious complications, particularly after noncardiac surgery. We therefore evaluated respiratory and other complications in noncardiac surgery patients taking or not taking statins preoperatively. ⋯ Preoperative statin use in noncardiac surgical patients was associated with slightly reduced odds of postoperative respiratory, infectious, and cardiovascular complications. However, the NNTs were high. Thus, despite the fact that statins appeared to be associated with lower odds of various complications, especially cardiovascular complications, our results do not support using statins specifically to reduce noncardiovascular complications after noncardiac surgery.

Hemodynamic Changes via the Lung Recruitment Maneuver Can Predict Fluid Responsiveness in Stroke Volume and Arterial Pressure During One-Lung Ventilation.
We aimed to evaluate the ability of lung recruitment maneuver-induced hemodynamic changes to predict fluid responsiveness in patients undergoing lung-protective ventilation during one-lung ventilation (OLV). ⋯ ΔSVRM and ΔMAPRM could predict hemodynamic responses after volume expansion during OLV.
