Reduction in Postoperative Right Ventricular Echocardiographic Indices Predicts Longer Duration of Vasoactive Support After Cardiac Surgery.
To assess perioperative right ventricular (RV) echocardiographic indices and their relationship to vasopressor and inotropic support in cardiac surgical patients. The authors hypothesized that a reduction in echocardiographic parameters of RV function would be associated with a longer duration of vasopressor and inotropic support in the intensive care unit (ICU). ⋯ Patients with post-CPB TAPSE <17 mmHg require a longer duration of inotropic support in the ICU. From all measured RV echocardiographic indices, post-CPB FAC is an independent predictor of vasopressor and inotropic support. A reduction of post-CPB TAPSE and FAC in patients undergoing cardiac surgery is indicative of RV dysfunction requiring a longer use of vasopressor and inotropic support and potentially longer stay in the cardiovascular ICU.

ReviewRole of Intraoperative Neuromonitoring to Predict Postoperative Delirium in Cardiovascular Surgery.
Postoperative delirium (POD) can occur in up to 50% of older patients undergoing cardiovascular surgery, resulting in hospitalization and significant morbidity and mortality. This study aimed to determine whether intraoperative neurophysiologic monitoring (IONM) modalities can be used to predict delirium in patients undergoing cardiovascular surgery. ⋯ Significant IONM changes are associated with an increased risk of POD in patients undergoing cardiovascular surgery. These findings offer a basis for future research and analysis of EEG and somatosensory evoked potential monitoring to predict, detect, and prevent POD.

Prevalence and Risk Factors for Chronic Postsurgical Pain After Thoracic Surgery: A Prospective Cohort Study.
Thoracic surgery is associated with one of the highest rates of chronic postsurgical pain (CPSP) among all surgical subtypes. Chronic postsurgical pain carries significant medical, psychological, and economic consequences, and further interventions are needed to prevent its development. This study aimed to determine the prevalence, characteristics, and risk factors associated with CPSP after thoracic surgery. ⋯ Approximately 1 in 3 patients will continue to have pain at 3 months after surgery, with a large proportion reporting neuropathic features. Risk factors for pain at 3 months may include preoperative anxiety and depression and acute postoperative pain.

Low-Volume Acute Normovolemic Hemodilution Does Not Reduce Allogeneic Red Blood Cell Transfusion in Cardiac Surgery in the Modern Era of Patient Blood Management: A Propensity Score-Matched Cohort Study.
Patients undergoing cardiac surgery often require blood transfusions, which are associated with increased morbidity and mortality. Patient blood management (PBM) strategies, including acute normovolemic hemodilution (ANH), have been implemented to minimize allogeneic transfusion requirements. Older studies suggested that ANH is associated with reduced transfusions; however, its effectiveness in the modern era of PBM remains unclear. ⋯ Low-volume ANH was not associated with a significant reduction in perioperative allogeneic RBC transfusion during cardiac surgery with CPB using low-priming-volume circuits. The benefits of low-volume ANH in reducing the requirement for RBC transfusion in the modern era of PBM may be smaller than reported previously.
