Nighttime Extubation Does Not Increase Risk of Reintubation, Length of Stay, or Mortality: Experience of a Large, Urban, Teaching Hospital.
In the intensive care unit (ICU), extubation failure has been associated with greater resource utilization and worsened clinical outcomes. Most recently, nighttime extubation (NTE) has been reported as a risk factor for increased ICU and hospital mortality. We hypothesized that, in a large, urban, university-affiliated hospital with multidisciplinary assessment for extubation, rigorously protocolized extubation algorithms, and expert airway managers available at all times of day for assessment of high-risk extubations, NTE would not confer additional risk of adverse clinical outcomes. ⋯ Patients who underwent NTE were not at increased risk of reintubation or in-hospital mortality. In addition, NTE was associated with a shortened duration of mechanical ventilation and hospital LOS. In health care systems with similar critical care delivery models, NTE may coincide with reduced resource utilization in appropriately selected patients.

Suppression of Human Natural Killer Cells by Different Classes of Opioids.
The use of regional and other opioid-sparing forms of anesthesia has been associated with a decrease in the recurrence of certain malignancies. Direct suppression of human natural killer cells by opioids has been postulated to explain this observation. However, the effect of different classes of opioids on suppression of natural killer cell cytotoxicity has not been systematically characterized. ⋯ Incubation of isolated natural killer cells with certain opioids causes a decrease in activity that is not observed after naloxone pretreatment. Suppression of natural killer cell cytotoxicity was observed with μ- and κ-receptor agonists but not δ-receptor agonists. These data suggest that the effect is mediated by μ- and κ-receptor agonism and that suppression is similar with many clinically used opioids.

Race/Ethnicity and Sex Both Affect Opioid Administration in the Emergency Room.
Although racial/ethnic and sex disparities have been examined in health care generally and pain management more specifically, the combined influence of these sociodemographic factors together has not been well documented. The aim of this study was to examine the association between administration of opioid analgesics in the emergency department (ED) and interaction of race/ethnicity and sex. ⋯ Based on National Hospital Ambulatory Medical Care Survey data from 2010 to 2014, there is no statistically significant interaction between race/ethnicity and sex for administration of opioid analgesia to people presenting to the ED with appendicitis or gallbladder disease. These results suggest that the joint effect of patient race/ethnicity and sex may not manifest in disparities in opioid management.
