Observational StudyComparison of Changes in Thoracic Fluid Content Between On-Pump and Off-Pump CABG by Use of Electrical Cardiometry.
To compare the changes in thoracic fluid content, PaO2/FIO2 ratio, plateau pressure, compliance, and postoperative ventilation duration in off-pump coronary artery bypass grafting (OPCAB) and on-pump coronary artery bypass grafting (ONCAB). ⋯ The change in TFC was greater in the ONCAB group, despite the fact that the fluid balance was higher in the OPCAB group. A higher TFC in ONCAB led to lower PaO2/FIO2 ratio, lower compliance, higher plateau pressures, and longer postoperative ventilation.

ReviewThe Intraoperative Assessment of Right Ventricular Function During Cardiac Surgery.
The importance of right ventricular (RV) dysfunction in patients undergoing cardiac surgery is well recognized. There is extensive literature regarding the accurate assessment of RV dysfunction with both echocardiography and hemodynamic data, but the majority of these studies are with transthoracic echocardiography (TTE) and in awake patients. Many of the tools used to assess the RV with TTE are angle-dependent and, therefore, may be inaccurate with transesophageal echocardiography (TEE). ⋯ The purpose of this review is to discuss the intraoperative tools available to the cardiac anesthesiologist for the assessment of RV function. The authors review the available literature surrounding intraoperative RV assessment, from subjective assessment to traditional objective tools that were developed for TTE and newer technology that can be adapted to both TTE and TEE. Future work should focus on whether or not these intraoperative RV assessment tools predict outcome after cardiac surgery.

ReviewEuglycemic Diabetic Ketoacidosis Associated With Sodium-Glucose Cotransporter-2 Inhibitors After Cardiac Surgery: A Review of Current Literature.
There is growing evidence to support the use of sodium-glucose cotransporter-2 (SGLT2) inhibitors for type 2 diabetes mellitus (T2DM) and the management of heart failure. As such, more patients undergoing cardiac surgery are on SGLT2-inhibitor therapy. Despite the numerous benefits of SGLT2 inhibitors on cardiac health, they can be associated with an increased risk of diabetic ketoacidosis, often with normal glucose levels (euglycemic diabetic ketoacidosis or EDKA), which potentially can be detrimental in this vulnerable patient population. ⋯ SGLT2 inhibitor-induced EDKA is a medical emergency that can be difficult to identify in the postcardiac surgical patient due to the overlap of signs and symptoms with other frequent scenarios in these patients. A reduction in SGLT2 inhibitor-associated EDKA can be mitigated by the appropriate perioperative discontinuation of the medication, clinical awareness, and early investigation to diagnose the condition, with emphasis on serum β-hydroxybutyrate. Future quality improvement initiatives are needed to assist in reducing EDKA in patients taking SGLT2 inhibitors in the perioperative surgical setting.

Randomized Controlled TrialEffect of Volatile Anesthesia Versus Total Intravenous Anesthesia on Postoperative Pulmonary Complications in Patients Undergoing Cardiac Surgery: A Randomized Clinical Trial.
The purpose of this study was to evaluate the effect of volatile anesthesia and propofol-based total intravenous anesthesia (TIVA) on postoperative pulmonary complications (PPCs) among patients undergoing cardiac surgery. ⋯ In adult patients undergoing cardiac surgery with cardiopulmonary bypass, general anesthesia with a volatile anesthetic compared with propofol-based TIVA had not reduced pulmonary complications within the first 7 days after surgery.

ReviewSepsis-induced cardiomyopathy reviewed: The case for early consideration of mechanical support.
Sepsis-induced cardiomyopathy (SCM) is an increasingly recognized problem encountered in critical care medicine. It generally is characterized as a decrease in left, right, or biventricular ejection fraction followed by a recovery of function over a period of days to weeks. Venoarterial extracorporeal membrane oxygenation (ECMO) has been used for the treatment of adults with various etiologies of shock, including cardiogenic and septic shock. This review summarizes current pathophysiologic mechanisms leading to SCM and provides a detection and treatment algorithm for SCM, as well as a discussion about the rationale and recent clinical data surrounding the use of ECMO and other forms of mechanical circulatory support for SCM.
