Preexisting Right Ventricular Dysfunction Is Associated With Higher Postoperative Cardiac Complications and Longer Hospital Stay in High-Risk Patients Undergoing Nonemergent Major Vascular Surgery.
To evaluate whether the presence of preexisting right ventricular (RV) dysfunction in high-risk patients undergoing nonemergent major vascular surgery is associated independently with higher incidents of postoperative cardiac complications and a longer length of hospital stay. ⋯ In this retrospective study of high-risk patients undergoing major vascular surgery, RV dysfunction was associated independently with a higher incidence of postoperative major cardiovascular events and longer length of hospital stays. Based on current findings, the prognostic value of RVD extends beyond the cardiac surgical cohort. Knowledge in management of patients with RVD in the perioperative setting should be understood by all anesthesiologists. Of note, a future study with a larger sample size is needed to validate the current findings given the small sample size of this study.

Comparative StudyMyocardial Protection in Minimally Invasive Mitral Valve Surgery: Retrograde Cardioplegia Alone Using Endovascular Coronary Sinus Catheter Compared With Combined Antegrade and Retrograde Cardioplegia.
To compare myocardial protection with retrograde cardioplegia alone with antegrade and retrograde cardioplegia in minimally invasive mitral valve surgery (MIMS). ⋯ Retrograde cardioplegia administration alone provided comparable myocardial protection to antegrade and retrograde cardioplegia during MIMS, but was not sufficient to achieve asystole in one-fifth of patients.

Observational StudyMethylene Blue Monotherapy Compared With Combination Therapy With Hydroxocobalamin for the Treatment of Refractory Vasoplegic Syndrome: A Retrospective Cohort Study.
To compare the efficacy of methylene blue with combination therapy with hydroxocobalamin in patients experiencing vasoplegic syndrome after cardiac surgery. ⋯ This is the first study to compare methylene blue monotherapy with combination therapy, which suggests there may be an advantage to combination therapy. Further characterization of ideal dosing, timing, and agent selection should be investigated on a larger scale format.

Fragility of Red Blood Cells Collected Under Different Conditions With a Cell Saver Device.
To quantify the degree of lethal and sublethal damage to red blood cells (RBCs) by cell saver (CS) processing among different conditions of shed blood in cardiac surgery. ⋯ This study reports the increase in sublethal and lethal injuries to RBCs from heparinized and non-heparinized blood after CS processing. CS-processed heparinized blood contained more sublethally injured RBCs compared to CS-processed non-heparinized blood. RBCs collected by squeezing blood-saturated gauze did not exhibit additional trauma. Further investigation is required to determine the clinical implications of transfusing rescued but injured RBCs using a CS.
