Association of intraoperative hypotension and pulmonary hypertension with adverse outcomes after orthotopic liver transplantation.
Various preoperative, surgical, and postoperative markers of impaired outcome after orthotopic liver transplantation have been reported, but the influence of intraoperative hemodynamic aberrations has not been thoroughly investigated. ⋯ Hemodynamic events are independently associated with adverse outcomes after orthotopic liver transplantation.

Randomized Controlled Trial Comparative Study Clinical TrialWhich anesthetic agent alters the hemodynamic status during pediatric catheterization? Comparison of propofol versus ketamine.
To compare the effects of propofol and ketamine on systemic and pulmonary circulations in pediatric patients scheduled for elective cardiac catheterization. ⋯ In children with cardiac shunting, the principal hemodynamic effect of propofol is a decrease in systemic vascular resistance. In children with intracardiac shunting, this results in an increase in right-to-left shunting and a decrease in the ratio of pulmonary to systemic blood flow, which may lead to arterial desaturation. Ketamine did not produce these changes. The authors suggested that during cardiac catheterization in children, both the anesthesiologists and cardiologists need to know that anesthetic agents can significantly alter the hemodynamic status in children with complex congenital heart defects and affect the results of hemodynamic calculations that are important for decision-making and treatment of these patients.

Clinical TrialPropofol-ketamine mixture for anesthesia in pediatric patients undergoing cardiac catheterization.
To evaluate the safety of a propofol-ketamine mixture to induce and maintain anesthesia in spontaneously breathing pediatric patents during cardiac catheterization. ⋯ The propofol-ketamine mixture is a safe, practical alternative for general anesthesia in pediatric patients undergoing cardiac catheterization.

Quantitative analysis of left ventricular regional wall motion with color kinesis during abdominal aortic cross-clamping.
The authors aimed to establish a technique for quantitative analysis of regional wall motion abnormality (RWMA) using color kinesis (CK) of transesophageal echocardiography (TEE) in surgical patients. This technique was used to determine whether RWMAs develop de novo after infrarenal aortic cross-clamping in patients undergoing vascular surgery with a preoperative dipyridamole thallium stress test (DTST). ⋯ A new method is available for clinical use, which is capable of visualizing RWMAs. These results suggest that new RWMAs introduced by aortic cross-clamping occur irrespective of the risk as assessed by preoperative DTST. CK with the new analysis method might be a useful tool to quantitatively evaluate RWMAs during surgery.
