Multicenter Study Observational Study
External validation of predictive models for acute kidney injury following cardiac surgery: A prospective multicentre cohort study.
Four predictive models for acute kidney injury associated with cardiac surgery were developed by Demirjian in the United States in 2012. However, the usefulness of these models in clinical practice needs to be established in different populations independent of that used to develop the models. ⋯ Overall, the lack of calibration of these models and the difficulty in using the models clinically because of the large number of variables limit their applicability.

Randomized Controlled Trial
Bilateral sternal infusion of ropivacaine and length of stay in ICU after cardiac surgery with increased respiratory risk: A randomised controlled trial.
The continuous bilateral infusion of a local anaesthetic solution around the sternotomy wound (bilateral sternal) is an innovative technique for reducing pain after sternotomy. ⋯ Because of a small size effect, and despite significant analgesic effects, this strategy failed to reduce the time spent in ICU.

Randomized Controlled Trial
Lung recruitment improves right ventricular performance after cardiopulmonary bypass: A randomised controlled trial.
Atelectasis after cardiopulmonary bypass (CPB) can affect right ventricular (RV) performance by increasing its outflow impedance. ⋯ Atelectasis after CPB impairs RV function but this can be resolved by lung recruitment using 10 cmH2O of PEEP.
