ReviewMachine Vision and Image Analysis in Anesthesia: Narrative Review and Future Prospects.
Machine vision describes the use of artificial intelligence to interpret, analyze, and derive predictions from image or video data. Machine vision-based techniques are already in clinical use in radiology, ophthalmology, and dermatology, where some applications currently equal or exceed the performance of specialty physicians in areas of image interpretation. While machine vision in anesthesia has many potential applications, its development remains in its infancy in our specialty. ⋯ The performance and potential uses of machine vision for anesthesia will only grow with the advancement of underlying machine vision algorithm technical performance developed outside of medicine, such as convolutional neural networks and transfer learning. This article summarizes recently published works of interest, provides a brief overview of techniques used to create machine vision applications, explains frequently used terms, and discusses challenges the specialty will encounter as we embrace the advantages that this technology may bring to future clinical practice and patient care. As machine vision emerges onto the clinical stage, it is critically important that anesthesiologists are prepared to confidently assess which of these devices are safe, appropriate, and bring added value to patient care.

Using Preanesthesia Clinic Visits to Improve Advance Directives Completion: An Interrupted Time Series Analysis.
Advance directives documentation can increase the likelihood that patient's wishes are respected if they become incapacitated. Unfortunately, completion rates are suboptimal overall, and disparities may exist, especially for vulnerable groups. We assessed whether implementing an initiative to standardize advance directives discussions during preanesthesia visits was associated with changes in rates of advance directives completion over time, and whether the association depends on race, insurance type, or income. ⋯ Standardizing advance directives discussions during preanesthesia visits was associated with more patients completing advance directives, particularly in vulnerable patient groups.

Clinical TrialMinimizing Lung Injury During Laparoscopy in Head-Down Tilt: A Physiological Cohort Study.
Increased intra-abdominal pressure during laparoscopy induces atelectasis. Positive end-expiratory pressure (PEEP) can alleviate atelectasis but may cause hyperinflation. Cyclic opening of collapsed alveoli and hyperinflation can lead to ventilator-induced lung injury and postoperative pulmonary complications. We aimed to study the effect of PEEP on atelectasis, lung stress, and hyperinflation during laparoscopy in the head-down (Trendelenburg) position. ⋯ Higher PEEP levels during laparoscopy in the head-down position facilitate lung-protective ventilation. Atelectasis and lung stress are reduced in the absence of global alveolar hyperinflation.

The Timing of Initiating Hydrocortisone and Long-term Mortality in Septic Shock.
Previous studies on the association between the timing of corticosteroid administration and mortality in septic shock focused only on short-term mortality and produced conflicting results. We performed a retrospective review of a large administrative database of intensive care unit (ICU) patients to evaluate the association between the timing of hydrocortisone initiation and short- and long-term mortality in septic shock. We hypothesized that a longer duration between the first vasopressor use for sepsis and steroid initiation was associated with increased mortality. ⋯ In patients with septic shock, initiating hydrocortisone >12 hours after vasopressor use was associated with an increased risk of both short-term and long-term mortality, and a prolonged length of hospital stay.

Assuring the Groundwork for Success: Mentorship, Sponsorship, and Allyship for Practicing Anesthesiologists.
The challenges facing the health care industry in the post-coronavirus disease 2019 (COVID-19) pandemic world are numerous, jeopardizing wellness, and performance. Maintaining engagement and fulfillment of anesthesiologists in their work is now a critical issue in various practice settings: academic, private practice, and corporate medicine. In this article, we offer insights on how mentorship, sponsorship, and allyship are important in the advancement of the anesthesiology workforce including women and underrepresented minorities inclusive of race, gender, and disability. ⋯ These 3 distinct yet interrelated concepts are defined with a discussion on the value of implementation. In addition, the concept of "belonging" and its importance in enhancing the culture in anesthesiology is explored. We believe that part of the solution to wellness, recruitment and retention and improved job satisfaction of clinicians is having an environment where mentorship, sponsorship, and allyship are foundational.
