Comparative Study Clinical TrialNew Noninvasive Method for the Assessment of Central Venous Oxygen Saturations in Critically Ill Patients.
To compare noninvasive external jugular vein oxygen saturations (SjvO2) and central venous oxygen saturation (ScvO2) from a blood sample in patients admitted to the intensive care unit. ⋯ Central venous oxygen saturation can be estimated reasonably by the continuous noninvasive measurement of SjvO2 using near-infrared spectroscopy.

Meta AnalysisComparison of Volatile Anesthetics Versus Propofol on Postoperative Cognitive Function After Cardiac Surgery: A Systematic Review and Meta-analysis.
To compare the effects of volatile anesthetics and propofol on neurocognitive function after cardiac surgery. ⋯ Unlike noncardiac surgery, there are no differences between volatile anesthetics and propofol regarding postoperative neurocognitive dysfunction after cardiac surgery.

Modification of Respiratory Drive and Lung Stress by Level of Support Pressure and ECMO Sweep Gas Flow in Patients With Severe COVID-19-Associated Acute Respiratory Distress Syndrome: an Exploratory Retrospective Analysis.
Patients with severe acute respiratory distress syndrome (ARDS) often exhibit an unusually strong respiratory drive, which predisposes them to effort-induced lung injury. Careful titration of support pressure via the ventilator and carbon dioxide removal via extracorporeal membrane oxygenation (ECMO) may attenuate respiratory drive and lung stress. ⋯ In patients with CARDS on pressure support ventilation, even moderate support pressure may lead to overassistance during assisted ventilation, which is only reflected by advanced monitoring of respiratory mechanics. Modifying carbon dioxide removal via the extracorporeal system profoundly affects respiratory effort and mechanics. Spontaneously breathing patients with CARDS may benefit from consequent carbon dioxide removal.

Observational StudyPerioperative Implementation of Low-Dose Pregabalin in an Enhanced Recovery After Cardiac Surgery Protocol: A Pre-Post Observational Study.
Determine the effect of low-dose pregabalin in the perioperative enhanced recovery after cardiac surgery protocol. ⋯ In this evaluation of perioperative pregabalin administration for patients requiring cardiac surgery, pregabalin reduced postoperative opioid use, with significant reductions on postoperative day 0, and without any significant increase in adverse reactions. However, no differences in intensive care unit length of stay, time to extubation, or mortality were noted. The implementation of low-dose perioperative pregabalin within an Enhanced Recovery After Cardiac Surgery protocol may be effective at reducing postoperative opioid use in the immediate postoperative period, and may be safe with regard to adverse events. Ideal dosing strategies have not been determined; thus, further randomized control trials with an emphasis on limiting confounding factors need to be conducted.
