Echocardiographic strain analysis by speckle tracking allows assessment of myocardial deformation during the cardiac cycle. Its clinical applications have significantly expanded over the last two decades as a sensitive marker of myocardial dysfunction with important diagnostic and prognostic values. Strain analysis has the potential to become a routine part of the perioperative echocardiographic examination for most anesthesiologist-echocardiographers but its exact role in the perioperative setting is still being defined. ⋯ Echocardiographic strain analysis is a powerful tool that allows seeing what conventional 2D imaging sometimes fails to reveal. It often provides pathophysiologic insight into various cardiac diseases at an early stage. Strain analysis is readily feasible and reproducible thanks to the use of highly automated software platforms. This technique shows promising potential to become a valuable tool in the arsenal of the anesthesiologist-echocardiographer and aid in perioperative risk-stratification and clinical decision-making.

Rib fracture(s) is a common and painful injury often associated with significant morbidity (e.g., respiratory complications) and high mortality rates, especially in the elderly. Risk stratification and prompt implementation of analgesic pathways using a multimodal analgesia approach comprise a primary endpoint of care to reduce morbidity and mortality associated with rib fractures. This narrative review aims to describe the most recent evidence and care pathways currently available, including risk stratification tools and pharmacologic and regional analgesic blocks frequently used as part of the broadly recommended multimodal analgesic approach. ⋯ Rib fracture(s) continues to be a serious diagnosis, with high rates of mortality, development of chronic pain, and disability. A multidisciplinary approach to management, combined with appropriate analgesia and adherence to care bundles/protocols, has been shown to decrease morbidity and mortality. Most of the risk-stratifying care pathways identified perform poorly in predicting mortality and complications after rib fracture(s).

In March 2023, the College of Physicians and Surgeons of Ontario (CPSO) updated their policy entitled Decision-Making for End-of-Life Care. This policy will significantly change the landscape and clinical practice in Canada's most populous province with respect to decision-making for resuscitation. The update interrupts approximately eight years of CPSO policy that has mandated physicians to perform cardiopulmonary resuscitation (CPR) and other resuscitative measures unless they can explicitly obtain consent in the form of a do-not-resuscitate or no-CPR order. ⋯ Livingstone, 2019 court decision which reaffirmed that physicians must only offer treatments that they think are within the standard of care and not offer treatments that are not likely to benefit their patient. In this commentary, we review the historical aspects of the CPSO policy from 2015 to 2023 and discuss how such a policy of a "consent to withhold" paradigm was ethically problematic and likely led to significant harm. We then review the updated CPSO policy, outline some remaining areas of uncertainty and challenges, and make recommendations for how to interpret this policy in clinical practice.

Nonclinical factors affecting intraoperative red blood cell transfusion: a systematic review.
There is significant variability in intraoperative red blood cell (RBC) transfusion practice. We aimed to use the theoretical domains framework (TDF) to categorize nonclinical and behavioural factors driving intraoperative RBC transfusion practice in a systematic review of the literature. ⋯ Open Science Framework ( https://osf.io/pm8zs/?view_only=166299ed28964804b9360c429b1218c1 ; first posted, 3 August 2022).
