Clinical evaluation of reflectance spectrophotometry for the measurement of gastric microvascular oxygen saturation in patients undergoing cardiopulmonary bypass.
To evaluate the impact of cardiopulmonary bypass (CPB) on gastric mucosal oxygen saturation assessed by reflectance spectrophotometry in patients undergoing coronary artery bypass graft surgery. ⋯ Reflectance spectrophotometry allowed the authors to assess gastric mucosal oxygen saturation with a high repetition rate, regardless of spontaneous circulation with pulsatile flow or nonpulsatile flow during CPB. This technique provided the means to monitor on-line the course of tissue oxygen saturation throughout the operative procedure. Reflectance spectrophotometry is an appropriate and sensitive assessment tool to monitor gastric mucosal oxygen saturation in patients undergoing CPB.

Transesophageal echocardiography for cardiac surgery in children.
To evaluate the usefulness of transesophageal echocardiography (TEE) for cardiac surgery in children. ⋯ TEE is a valuable diagnostic tool for monitoring during cardiac surgery in children. The person who performs the TEE should use it carefully after obtaining thorough knowledge of the pathophysiology of pediatric cardiac diseases, their surgical indications, and how specific surgical procedures are done.

Current practice of internal jugular venous cannulation in a university anesthesia department: influence of operator experience on success of cannulation and arterial injury.
To describe current cannulation of the internal jugular vein (CIJV) practice in a university anesthesia department. ⋯ U-CIJV offers incomplete protection against arterial injury in this practice compared with the literature. A possible solution is the ultrasound needle guide, which may minimize arterial injury, especially with junior operators.

Mechanisms behind operating room blood transfusions in coronary artery bypass graft surgery patients with insignificant bleeding.
To investigate situations in cardiac surgery when transfusions are sometimes used for indications other than to compensate for surgical bleeding. ⋯ Some patients are transfused because of institutional bias of an anticipated need rather than for true surgical bleeding. A concern of hemodilution from standard CPB circuits suggests a possible advantage with low-priming volume for smaller adult female patients.

Prediction of excessive bleeding after coronary artery bypass graft surgery: the influence of timing and heparinase on thromboelastography.
To compare the ability of thromboelastography, when done at either 10 or 60 minutes after protamine reversal of heparin, to predict excessive bleeding after coronary artery bypass graft (CABG) surgery and to investigate, with the use of heparinase, whether heparin contamination was responsible for the difference, if any. ⋯ This study suggests that timing and the use of heparinase influence the predictive ability of thromboelastography, but its usefulness as a sole predictor of post-CABG surgery bleeding is limited.
