Observational StudyReinfusate Heparin Concentrations Produced by Two Autotransfusion Systems.
Cell saver reinfusate ideally should contain low, clinically insignificant heparin concentrations. The American Association of Blood Banks has defined the clinically insignificant threshold as 0.5 IU/mL. Furthermore, there is uncertainty about the meaning of cell saver "heparin elimination rates." These concerns prompted the authors' independent investigation of reinfusate heparin concentrations of devices used in their institution. It was hypothesized that cell saver reinfusates contain clinically insignificant heparin concentrations. ⋯ Sorin (Dideco) Electa reinfusates contained heparin concentrations below the American Association of Blood Banks recommended threshold in 90.6% of cases, while Sorin Xtra reinfusate heparin concentrations exceeded this recommendation in 56% of cases. Measurement of cell saver reinfusate heparin concentrations necessitates the use of a modified chromogenic assay. Studies explicitly should confirm that such a modification was indeed used. Periodic quality control of reinfusate composition is recommended.

Observational StudyPreoperative Electrocardiogram Score for Predicting New-Onset Postoperative Atrial Fibrillation in Patients Undergoing Cardiac Surgery.
To investigate if electrocardiogram (ECG) markers from routine preoperative ECGs can be used in combination with clinical data to predict new-onset postoperative atrial fibrillation (POAF) following cardiac surgery. ⋯ ECG markers obtained from a routine preoperative ECG may be helpful in predicting new-onset POAF in patients undergoing cardiac surgery.

Use of Postoperative Peak Arterial Lactate Level to Predict Outcome After Cardiac Surgery.
In the present study, the authors investigated the predictive value of postoperative peak arterial lactate levels for early and late mortality after cardiac surgery. ⋯ Postoperative peak arterial lactate level in patients undergoing cardiac surgery is an independent predictor for both early and late mortality.

Observational StudyDoes Postoperative Cardiac Troponin-I Have Any Prognostic Value in Predicting Midterm Mortality After Congenital Cardiac Surgery?
This study evaluated the prognostic value of postoperative cardiac troponin-I (cTnI) in predicting all-cause mortality up to 3 months after normothermic congenital cardiac surgery. ⋯ This study did not find that postoperative cTnI concentration predicted midterm mortality after normothermic congenital heart surgery. (ClinicalTrials.gov identifier: NCT01616394).
