Observational StudyThe Validation of Cardiac Index and Stroke-Volume Variation Measured by the Pulse-Wave Transit Time-Analysis Versus Conventional Pulse-Contour Analysis After Off-Pump Coronary Artery Bypass Grafting: Observational Study.
To compare the reliability of cardiac index (CI) and stroke-volume variation (SVV) measured by the pulse-wave transit-time (PWTT) method using estimated continuous cardiac output (esCCO) technique with conventional pulse-contour analysis after off-pump coronary artery bypass grafting (OPCAB). ⋯ The overall performance of CIesCCO and esSVV versus CIPCA and SVVPCA is not clinically acceptable. A further improvement of the PWTT algorithm may be required for an accurate and precise assessment of CI and SVV.

Interaction Between Platelet and Fibrinogen on Clot Strength in Healthy Patients.
The purpose of this study was to explore the relationship between platelet concentration (PLT) (× 109/L) and clot strength measured by thromboelastography maximum amplitude (TEG-MA) in healthy volunteers without a history of coagulation abnormalities. Secondarily, the relationship between fibrinogen (mg/dL) and TEG-MA was analyzed. ⋯ In healthy patients, a PLT of 60 × 109/L was associated with normal clot strength (TEG-MA ≥53 mm), and there was little change in clot strength with PLT >90 × 109/L. Although prior analyses described the contributions of platelets and fibrinogen toward clot strength, they are presented and discussed independently. The data above described clot strength as an interaction among them. Future analyses and clinical care should evaluate and recognize the interplay.

Postcardiac Surgery Euglycemic Diabetic Ketoacidosis in Patients on Sodium-Glucose Cotransporter 2 Inhibitors.
To evaluate sodium-glucose cotransporter 2 inhibitors (SGLT2i) use and complications (euglycemic diabetic ketoacidosis [eDKA] rate, mortality, infection, hospital, and cardiovascular intensive care unit [CVICU] length of stay [LOS]) in patients undergoing cardiac surgery. ⋯ Postoperative eDKA occurred in 15% of patients on an SGLT2i prior to cardiac surgery, and was associated with longer CVICU LOS. Future studies into SGLT2i management perioperatively are important.
