Observational StudyPreoperative Depression Symptom Severity and Its Impact on Adherence to Preoperative Beta-Blocker Therapy.
To test the association among depression symptoms, distressed personality type, and preoperative beta-blocker nonadherence and to estimate the prevalence of untreated major depression in this population. ⋯ Patients with symptoms of depression on chronic beta-blocker therapy are susceptible to medication nonadherence on the day of surgery. Most surgical patients with symptoms of major depression lack a diagnosis of depression. Preoperative depression screening may thus (1) identify a population at increased risk of beta-blocker withdrawal, and (2) identify patients who may benefit from anesthesiologist-initiated referral for this treatable condition.

Dose-Dependent Effects of Intraoperative Low Volume Red Blood Cell Transfusions on Postoperative Outcomes in Cardiac Surgery Patients.
To determine the incremental risk associated with each intraoperative red blood cell transfusion in cardiac surgery patients. ⋯ There is a step-wise increase in length of postoperative intubation with each red blood cell transfusion in patients undergoing cardiac surgery. Each additional unit of intraoperative RBC transfusion also may increase postoperative infectious complications. Thus, even single-unit reductions in red blood cell transfusions may have significant impact on outcomes.

P-Wave Characteristics on Routine Preoperative Electrocardiogram Improve Prediction of New-Onset Postoperative Atrial Fibrillation in Cardiac Surgery.
To test the hypothesis that including preoperative electrocardiogram (ECG) characteristics with clinical variables significantly improves the new-onset postoperative atrial fibrillation prediction model. ⋯ Several p-wave characteristics are independently associated with postoperative atrial fibrillation. Addition of these parameters improves the postoperative atrial fibrillation prediction model.
