Observational StudyAre Serum Potassium and Magnesium Levels Associated with Atrial Fibrillation After Cardiac Surgery?
Potassium and magnesium are frequently administered after cardiac surgery to reduce the risk of atrial fibrillation (AF). The evidence for this practice is unclear. This study was designed to evaluate the relationship between serum potassium and magnesium levels and AF after cardiac surgery. ⋯ Maintaining a serum potassium concentration ≥4.5 mmol/L after cardiac surgery may reduce the incidence of postoperative AF. Magnesium supplementation was associated with an increased risk of postoperative AF. Prospective randomized trials are required to clarify these associations.

Observational StudyUse of Pulmonary Artery Pulsatility Index in Cardiac Surgery.
This study evaluated whether the pulmonary artery pulsatility index (PAPi) collected before and after cardiopulmonary bypass (CPB) is predictive and diagnostic of new onset right ventricular (RV) failure in the elective cardiac surgical population. ⋯ PAPi measured pre-CPB is a potential predictor and marker of post-CPB RV dysfunction and may have diagnostic utility in cardiac surgery. Additional, large-scale studies are needed to confirm this finding.
