Observational Study
The base excess gap is not a valid tool for the quantification of unmeasured ions in cardiac surgical patients: A retrospective observational study.
The base excess gap (BE(gap)) method is commonly used for the quantification of unmeasured ions in critically ill patients. However, it has never been validated against the standard quantitative acid-base approach. ⋯ The BE gap method cannot reliably quantify the unmeasured ion excess in cardiac surgical patients. Clinicians should use the full Stewart-Figge model for quantitative acid-base assessments.

Observational Study
How can we best predict acute kidney injury following cardiac surgery?: A prospective observational study.
Several models for predicting acute kidney injury following cardiac surgery have been published, and various end-point definitions have been used. ⋯ The risk of acute kidney injury can be accurately predicted using preoperative variables. Serum creatinine concentration was more accurate than estimated glomerular filtration rate or creatinine clearance. Intraoperative variables slightly improved the model, but did not seem to outweigh the advantages of a preoperative model.
