The COVID-19 outbreak has led to 80,409 diagnosed cases and 3,012 deaths in mainland China based on the data released on March 4, 2020. Approximately 3.2% of patients with COVID-19 required intubation and invasive ventilation at some point in the disease course. Providing best practices regarding intubation and ventilation for an overwhelming number of patients with COVID-19 amid an enhanced risk of cross-infection is a daunting undertaking. ⋯ Timely, but not premature, intubation is crucial to counter a progressively enlarging oxygen debt despite high-flow oxygen therapy and bilevel positive airway pressure ventilation. Thorough preparation, satisfactory preoxygenation, modified rapid sequence induction, and rapid intubation using a video laryngoscope are widely used intubation strategies in Wuhan. Lung-protective ventilation, prone position ventilation, and adequate sedation and analgesia are essential components of ventilation management.

Multicenter Study
Opioid Stewardship Program and Postoperative Adverse Events: A Difference-in-differences Cohort Study.
A 6-month opioid use educational program consisting of webinars on pain assessment, postoperative and multimodal pain opioid management, safer opioid use, and preventing addiction coupled with on-site coaching and monthly assessments reports was implemented in 31 hospitals. The authors hypothesized the intervention would measurably reduce and/or prevent opioid-related harm among adult hospitalized patients compared to 33 nonintervention hospitals. ⋯ A 6-month opioid educational intervention did not reduce opioid adverse events or alter opioid use in hospitalized patients. The authors' findings suggest that despite opioid and multimodal analgesia awareness, limited-duration educational interventions do not substantially change the hospital use of opioid analgesics.

The coronavirus disease 2019, named COVID-19 officially by the World Health Organization (Geneva, Switzerland) on February 12, 2020, has spread at unprecedented speed. After the first outbreak in Wuhan, China, Chinese anesthesiologists encountered increasing numbers of infected patients since December 2019. ⋯ As the epidemic situation has lasted for months (thus far), special platforms have also been set up to provide free mental health care to all anesthesia providers participating in acute and critical caring for COVID-19 patients. The current article documents the actions taken, lesson learned, and future work needed.

As more older adults undergo surgery, it is critical to understand the long-term effects of surgery on brain health, particularly in relation to the development of Alzheimer's disease. This study examined the association of surgical hospitalization with subsequent brain β-amyloid deposition in nondemented older adults. ⋯ The results do not support an association between surgical hospitalization and elevated brain amyloid.

Comment Randomized Controlled Trial Comparative Study
Neurally Adjusted Ventilatory Assist versus Pressure Support Ventilation in Difficult Weaning: A Randomized Trial.
Difficult weaning frequently develops in ventilated patients and is associated with poor outcome. In neurally adjusted ventilatory assist, the ventilator is controlled by diaphragm electrical activity, which has been shown to improve patient-ventilator interaction. The objective of this study was to compare neurally adjusted ventilatory assist and pressure support ventilation in patients difficult to wean from mechanical ventilation. ⋯ In patients difficult to wean, neurally adjusted ventilatory assist decreased the duration of weaning and increased ventilator-free days.
