Meta AnalysisAmino Acid Infusion for Perioperative Functional Renal Protection: A Meta-analysis.
Acute kidney injury (AKI) is a common perioperative complication. To date, no single intervention has been proven effective for AKI prevention in this setting. However, intravenous amino acids (AA) administration may recruit renal functional reserve and, thereby, attenuate the perioperative loss of the glomerular filtration rate. ⋯ This meta-analysis suggests that AA administration likely decreased the perioperative incidence of AKI.

Outflow Graft Tamponade: An Underrecognized Cause of Obstruction.
Left ventricular assist device (LVAD) outflow graft obstruction can result in severe clinical deterioration. Underlying mechanisms may vary depending on the location. Outflow graft tamponade due to external compression can be under recognized. Management of this complication varies across institutions and a uniform approach has yet to be elucidated. ⋯ Conclusions: Outflow graft tamponade is a form outflow graft obstruction with a variable presentation that can result in significant hemodynamic compromise. It is amenable to both surgical and percutaneous interventions that restore LVAD function.

Randomized Controlled Trial Multicenter Study Comparative StudyThe Effects of Angiotensin II versus Norepinephrine on Pulmonary Vascular Resistance in Cardiac Surgery: Post Hoc Analysis of a Randomized Controlled Trial.
To assess whether angiotensin II infusion increases pulmonary vascular resistance (PVR) relative to norepinephrine. ⋯ The results of this study suggest that in cardiac surgery patients and at doses used in the prior feasibility study, angiotensin II did not have significant effects on the pulmonary vasculature compared with norepinephrine. Moreover, at doses used in this study, neither drug appeared to have a substantial effect on the pulmonary circulation relative to surgical and patient factors.
