Randomized Controlled Trial Comparative Study
Remimazolam to prevent hemodynamic instability during catheter ablation under general anesthesia: a randomized controlled trial.
Maintaining hemodynamic stability during cardiac ablation under general anesthesia is challenging. Remimazolam, a novel ultrashort-acting benzodiazepine, is characterized by maintaining comparatively stable blood pressure and does not influence the cardiac conduction system, which renders it a reasonable choice for general anesthesia for cardiac ablation. We aimed to evaluate whether remimazolam is associated with a decreased incidence of intraoperative hypotension compared with desflurane. ⋯ ClinicalTrials.gov (NCT05486377); first submitted 1 August 2022.

The ordering of routine blood test panels in advance is common in intensive care units (ICUs), with limited consideration of the pretest probability of finding abnormalities. This practice contributes to anemia, false positive results, and health care costs. We sought to understand practices and attitudes of Canadian adult intensivists regarding ordering of blood tests in critically ill patients. ⋯ Most respondents to this survey perceived that unnecessary blood testing occurs in the ICU. The survey identified possible strategies to decrease the number of blood tests.

The COVID-19 pandemic created conditions of scarcity that led many provinces within Canada to develop triage protocols for critical care resources. In this study, we sought to undertake a narrative synthesis and ethical analysis of early provincial pandemic triage protocols. ⋯ Early provincial COVID-19 triage protocols were developed by dedicated expert committees under challenging circumstances. Nonetheless, few were publicly available, and public consultation was limited. No protocols were ever implemented, including during periods of extreme critical care surge. A national approach to pandemic triage that incorporates additional aspects of procedural justice should be considered in preparation for future pandemics.

Case Reports
Intraoperative hemodialysis with supra- and infradiaphragmatic catheters for liver transplantation.
The benefits of intraoperative dialysis during orthotopic liver transplantation remain controversial. In patients with anuric renal failure and portopulmonary hypertension, maintaining venous return during caval clamping and unclamping along with minimizing fluid overload is critical to avoiding right ventricular strain and failure. ⋯ We report on the use two hemodialysis catheters in a patient undergoing orthotopic liver transplantation as a circuit for simultaneous anuric hepatorenal syndrome and moderate pulmonary hypertension with right ventricular dilation and dysfunction. We believe this technique was instrumental in the patient's successful transplant.
