We aimed to elucidate whether postinduction hypotension (PIH), defined as hypotension between anesthesia induction and skin incision, and intraoperative hypotension (IOH) are associated with postoperative mortality. ⋯ Despite limitations, including power and residual confounding, postoperative mortality was associated with IOH but not with PIH.

In 2021, Nova Scotia, Canada, became the first jurisdiction in North America to adopt a deemed consent organ donation system under its revised Human Organ and Tissue Donation Act. This study sought to understand the early experiences of program staff and clinicians involved in implementing this legislation. ⋯ Deemed consent legislation had limited impact on clinician's day-to-day practices, because of lack of infrastructure changes and infrequent donation opportunities. Nevertheless, participants felt the introduction of deemed consent in Nova Scotia eased conversations between families of potential donors and clinicians. These findings should be used to inform ongoing implementation of deemed consent and be considered by those contemplating similar legislative changes.

Obtaining an objective, reproducible, and accurate assessment of volume status is one of the more difficult tasks in the perioperative arena. Since its advent in 2020, the Venous Excess Ultrasound (VExUS) score has gained popularity in the minimally invasive assessment of venous congestion. The VExUS exam has been well described as an additional series of images (hepatic vein, portal vein, and intrarenal vein) obtained with a phased-array probe during a transthoracic echocardiogram. Nevertheless, there are no descriptions of comprehensive VExUS exams performed using transesophageal echocardiography (TEE)-a modality that is routinely employed in patients undergoing cardiac surgery. ⋯ Given the risks of fluid overload in critically ill cardiac surgery patients, TEE-supported VExUS examination may be a way to reduce morbidity in this population.
