Older critically ill patients with COVID-19 have been the most vulnerable during the ongoing pandemic, with men being more prone to hospitalization and severe disease than women. We aimed to explore sex-specific differences in treatment and outcome after intensive care unit (ICU) admission in this cohort. ⋯ gov (NCT04321265); registered 25 March 2020).

After weaning from cardiopulmonary bypass (CPB), the radial artery pressure is frequently lower than the central pressure as reflected by femoral pressure. This discrepancy may cause improper blood pressure management. In this study, we aimed to evaluate the risk factors related to developing a significant postbypass femoral-to-radial pressure gradient, including the incidence of complications related to femoral pressure monitoring. ⋯ Our study showed that old age, smaller BSA, prolonged aortic cross-clamping time, and intraoperative epinephrine use were associated with developing a significant postbypass femoral-to-radial pressure gradient in cardiovascular surgery. Considering monitoring-related complications occurred very infrequently, it might be helpful to monitor both radial and femoral pressure simultaneously in patients with these risk factors for appropriate blood pressure management. Nevertheless, further studies are needed to confirm our findings because our results are limited by a retrospective design and residual confounding factors.

Observational Study
Development of local guidelines to prevent perioperative hypothermia in children: a prospective observational cohort study.
Perioperative hypothermia (PH) is defined as core body temperature < 36°C during the perioperative period. The incidence of PH is not well established in children because of variations in perioperative temperature monitoring and control measures. We sought to 1) establish the incidence of pediatric PH, 2) assess its adverse outcomes, and 3) identify risk factors in our pediatric population to develop local guidelines for prevention of PH. ⋯ Perioperative hypothermia was a common problem in our pediatric population and was associated with significant adverse outcomes. Guidelines developed based on risk factors identified in the local context can facilitate workflow and implementation within the institution.

Wait list times for total joint arthroplasties have been growing, particularly in the aftermath of the COVID-19 pandemic. Increasing operating room (OR) efficiency by reducing OR time and associated costs while maintaining quality allows the greatest number of patients to receive care. ⋯ Spinal anesthesia in the context of a dedicated block room reduced both anesthesia-controlled time and total OR time. This did not translate into a reduction in incremental cost in the spinal anesthesia group.
