The application of a surgical face mask over oxygen delivery devices is now a widespread recommendation in the setting of the Coronavirus disease pandemic. This addition is designed to reduce droplet spread, but this also changes the nature of these devices, and may alter the amount of oxygen delivered to a patient. This research investigated how placing a surgical face mask over both a simple plastic mask ("Hudson mask") and nasal cannula altered the concentration of available oxygen measured at the nares. ⋯ The addition of a surgical face mask over both nasal cannula and a Hudson mask resulted in an increased available oxygen concentration. This may be valuable where more advanced oxygen devices are not available, or alternatively providing adequate supplemental oxygen at lower flow rates and thus making critical savings in oxygen usage.

Objective: To compare the characteristics, treatments and 6-month functional outcomes of patients with coronavirus disease 2019 (COVID-19) versus non-COVID-19 viral pneumonitis supported by venovenous extracorporeal membrane oxygenation (VV-ECMO). Design: Prospective, observational cohort study in seven intensive care units (ICUs) across Australia. Participants: Patients admitted to participating ICUs with laboratory-confirmed COVID-19 or viral pneumonitis requiring VV-ECMO. ⋯ Overall disability, health-related quality of life, and mortality were similar, but ICU and hospital length of stay were significantly longer in patients with COVID-19. Conclusions: Six-month functional outcomes and mortality were similar between COVID-19 and viral pneumonitis patients treated with VV-ECMO. However, length of stay was longer in COVID-19 patients, which may have resource implications.

Meta Analysis Comparative Study
A Systematic Review and Meta-analysis of Randomized Controlled Trials Comparing Intraoperative Red Blood Cell Transfusion Strategies.
The objective of this work was to carry out a meta-analysis of RCTs comparing intraoperative RBC transfusion strategies to determine their impact on postoperative morbidity, mortality, and blood product use. ⋯ Intraoperative restrictive transfusion strategies decreased perioperative transfusions without added postoperative morbidity and mortality in 12/14 trials. Two trials reported worse outcomes. Given trial design and generalizability limitations, uncertainty remains regarding the safety of broad application of restrictive transfusion triggers in the operating room. Trials specifically designed to address intraoperative transfusions are urgently needed.

ReviewAccuracy of ultrasonography predicting spread location following intraneural and subparaneural injections: a scoping review.
Ultrasonography is useful for detecting intraneural injections. However, the reliability of the sonographic findings of intraneural and subparaneural injections in terms of true spread location and their association with intrafascicular deposits has not been systematically evaluated. ⋯ Our results suggest that sonographic parameters of intraneural and subparaneural injections are reliable in terms of detecting spread location. Intrafascicular injectate deposition may occur, albeit infrequently, particularly in the proximal brachial plexus. Our findings support the judicious interrogation of sonographic parameters suggestive of incipient intraneural injection.

ReviewNarrative Medicine: Perioperative Opportunities and Applicable Health Services Research Methods.
Narrative medicine is a humanities-based discipline that posits that attention to the patient narrative and the collaborative formation of a narrative between the patient and provider is essential for the provision of health care. In this Special Article, we review the basic theoretical constructs of the narrative medicine discipline and apply them to the perioperative setting. ⋯ We then examine the importance of incorporating narrative medicine into medical education and residency training and evaluate the literature on such narrative medicine didactics. Finally, we discuss applying health services research, specifically qualitative and mixed methods, in the rigorous evaluation of the efficacy and impact of narrative medicine clinical programs and medical education curricula.
