Historically, cardiac surgery patients have often been managed with supraphysiologic intraoperative oxygen levels to protect against the risks of cellular hypoxia inherent in the un-physiologic nature of surgery and cardiopulmonary bypass. This may result in excessive reactive oxygen species generation and exacerbation of ischemia-reperfusion injury. In this review, we synthesize all available data from randomized controlled trials (RCTs) to investigate the impact that hyperoxia has on postoperative organ dysfunction, length of stay, and mortality during adult cardiac surgery. ⋯ Hyperoxia had minimal impact on organ dysfunction, length of stay, and mortality in adult cardiac surgery. The current evidence base is small, heterogeneous, and at risk of bias.

Randomized Controlled Trial Multicenter StudyThe Effect of IV Amino Acid Supplementation on Mortality in ICU Patients May Be Dependent on Kidney Function: Post Hoc Subgroup Analyses of a Multicenter Randomized Trial.
We investigated whether preexisting kidney function determines if ICU patients may benefit from increased (2.0 g/kg/d) protein intake. ⋯ In this post hoc, hypothesis-generating, subgroup analysis, we observed reduced mortality and improved estimated glomerular filtration rate in ICU patients with normal kidney function who were randomly allocated to receive increased protein intake (up to 2.0 g/kg/d). We strongly recommend confirmation of these results in trials with low risk of bias before this treatment is recommended for routine care.

Cardiac output-based fluid optimization for kidney transplant recipients: a proof-of-concept trial.
Intravenous fluid management for deceased donor kidney transplantation is an important, modifiable risk factor for delayed graft function (DGF). The primary objective of this study was to determine if goal-directed fluid therapy using esophageal Doppler monitoring (EDM) to optimize stroke volume (SV) would alter the amount of fluid given. ⋯ Goal-directed fluid therapy did not alter the volume of fluid administered or the incidence of complications. This proof-of-concept trial provides needed data for conducting a larger trial to determine the influence of fluid therapy on the incidence in DGF in deceased donor kidney transplantation.

The Impact of Postreperfusion Syndrome on Acute Kidney Injury in Living Donor Liver Transplantation: A Propensity Score Analysis.
Postreperfusion syndrome (PRS) has been shown to be related to postoperative morbidity and graft failure in orthotopic liver transplantation. To date, little is known about the impact of PRS on the prevalence of postoperative acute kidney injury (AKI) and the postoperative outcomes after living donor liver transplantation (LDLT). The purpose of our study was to determine the impact of PRS on AKI and postoperative outcomes after LDLT surgery. ⋯ We demonstrated that the magnitude and duration of hypotension caused by PRS is a factor contributing to the development of AKI and residual renal dysfunction 3 months after LDLT.
