Observational StudyDynamic Tests to Predict Fluid Responsiveness After Off-Pump Coronary Artery Bypass Grafting.
To test the hypothesis that a positive end-expiratory pressure test and the mini-fluid challenge predict fluid responsiveness in patients after off-pump coronary artery bypass grafting. ⋯ Both the positive end-expiratory pressure test and the mini-fluid challenge test are feasible after off-pump coronary artery bypass grafting and can be used to predict fluid responsiveness in these patients.

Observational StudyUse of Transesophageal Echocardiogram and Interdisciplinary Approach to Intraoperative Management of Renal Cell Carcinoma With Inferior Vena Cava Invasion.
Report experience of patients undergoing surgery for resection of renal cell carcinoma with inferior vena cava invasion and use of transesophageal echocardiogram (TEE). ⋯ The surgical management of renal cell carcinoma with inferior vena cava tumor extension is complex. High-grade tumors require individualized treatment. Successful outcomes require collaboration between surgeons and anesthesiologists. Patients with level IIIb to IV tumor invasion benefit from TEE assessment and monitoring, which may be life-saving, and cardiac anesthesia should be involved in those types of cases.

Fifty Percent Effective Dose of Intranasal Dexmedetomidine Sedation for Transthoracic Echocardiography in Children With Cyanotic and Acyanotic Congenital Heart Disease.
To determine the 50% and 95% effective dose of intranasal dexmedetomidine sedation for transthoracic echocardiography in children with cyanotic and acyanotic congenital heart disease. ⋯ The 50% (95% confidence intervals) effective doses of intranasal dexmedetomidine sedation for transthoracic echocardiography were 3.2 (2.78-3.55) μg/kg and 1.9 (1.69-2.06) μg/kg in children with cyanotic and acyanotic congenital heart disease, respectively.

Microvascular Alterations During Cardiac Surgery Using a Heparin or Phosphorylcholine-Coated Circuit.
Heparin biocompatible coating frequently is used to reduce inflammation and blood coagulation during cardiopulmonary bypass (CPB) in cardiac surgery. Whether heparin coating is protective or damaging to the vascular endothelium is unclear. The authors investigated whether heparin-coated (HC) circuits are associated with better preservation of microcirculatory perfusion and glycocalyx dimensions compared with nonheparin phosphorylcholine-coated (PC) circuits. ⋯ The use of an HC circuit is associated with better preservation of the endothelial glycocalyx compared with PC circuits, whereas microcirculatory perfusion was disturbed equally in both groups. Hence, CPB-induced microcirculatory perfusion disturbances seem to be coating independent.
