ReviewAntinociceptive Agents as General Anesthetic Adjuncts: Supra-additive and Infra-additive Interactions.
The hypothesis "General anesthesia consists of producing both loss of consciousness and the inhibition of noxious stimuli reaching the brain and causing arousal" was used as a basis for the review of published data on general anesthetic interactions with antinociceptive agents: opioids, α 2 adrenergic agonists, and systemic sodium channel blockers. This review is focused on a specific type of anesthetic interaction-the transformation of antinociceptive agents into general anesthetic adjuncts. The primary aim is to answer 2 questions. ⋯ The following terms related to drug interactions were used: anesthetic interactions, synergy, antagonism, isobolographic analysis, response surface analysis, and fractional analysis. The interactions of antinociceptive agents with general anesthetics result in a decrease of general anesthetic requirements, which differ for each of the components of general anesthesia: hypnosis, immobility, and hemodynamic response to noxious stimulation. Most studies of the nature of anesthetic interactions are related to opioid-general anesthetic combinations, and their conclusions usually confirm supra-additivity.

Implementation of Nephroprotective Measures to Prevent Acute Kidney Injury in Septic Patients: A Retrospective Cohort Study.
Sepsis remains the leading cause of mortality in critically ill patients, and mortality is increased when acute kidney injury (AKI) occurs. The Kidney Disease: Improving Global Outcomes (KDIGO) guideline recommends the implementation of supportive measures in patients at high risk for AKI. However, it remains unclear to what extent these nephroprotective measures are implemented in daily clinical practice in critically ill patients, especially those with high-risk exposures such as sepsis. ⋯ Implementation of the KDIGO bundle is poor in patients with sepsis but may be associated with improved outcomes.

Observational StudyAssociation Between Intraoperative Landiolol Use and In-Hospital Mortality After Coronary Artery Bypass Grafting: A Nationwide Observational Study in Japan.
Ischemic heart disease is a leading cause of death worldwide, and coronary artery bypass grafting (CABG) is a major treatment. Landiolol is an ultra-short-acting beta-antagonist known to prevent postoperative atrial fibrillation. However, the effectiveness of intraoperative landiolol on mortality remains unknown. This study aimed to evaluate the association between intraoperative landiolol use and the in-hospital mortality in patients undergoing CABG. ⋯ Intraoperative landiolol use was associated with decreased in-hospital mortality in patients undergoing CABG. Further randomized controlled trials are required to confirm these findings.

Women Representation in Anesthesiology Society Leadership Positions.
Although the number of women in medicine has increased, women remain underrepresented in leadership positions, specifically in medical societies. Specialty societies in medicine are influential in networking, career advancement, research and education opportunities, and providing awards and recognition. The goals of this study are to examine the representation of women in leadership positions in anesthesiology societies compared to women society members and women anesthesiologists and to analyze the trend in women society presidents over time. ⋯ This study suggests that anesthesia societies may be more inclusive of women in leadership positions compared to other specialty societies. Although in anesthesiology, women remain underrepresented in academic leadership roles, there is a higher proportion of women in leadership roles in anesthesiology societies than proportion of women in the anesthesia workforce.

The Physician Anesthesia Workforce in Canada From 1996 to 2018: A Longitudinal Analysis of Health Administrative Data.
A robust anesthesia workforce is essential to the provision of safe surgical, obstetrical, and critical care but information describing the physician anesthesia workforce and volume of clinical services delivered in Canada is limited. This study examines the Canadian physician anesthesia workforce, exploring trends in physician characteristics and activity levels over time. Practice patterns of specialist anesthesiologists and family physician anesthetists (FPAs) working in urban and rural communities were of particular interest. ⋯ This study provides foundational information regarding anesthesia workforce capacity over a 22-year period, including insights into demographics, locations of practice, and clinical volumes. The results do not quantify the gap between service capacity and need; however, they support the need for a national workforce strategy to achieve equitable access to sustainable anesthesia services in Canada, particularly for rural communities.
