Observational StudyCorrelation of Carotid Doppler Blood Flow With Invasive Cardiac Output Measurements in Cardiac Surgery Patients.
Carotid Doppler ultrasound has been a topic of recent interest, as it may be a promising noninvasive hemodynamic monitoring tool. In this study, the relation between carotid artery blood flow and invasive cardiac output (CO) was evaluated. ⋯ In cardiac surgery patients, carotid artery blood flow correlated moderately with invasive CO measurements. However, the trending ability of carotid artery blood flow was poor, and carotid artery-derived CO tended not to be interchangeable with invasive CO.

Dopamine Reverses Lung Function Deterioration After Cardiopulmonary Bypass Without Affecting Gas Exchange.
To investigate the effects of dopamine on the adverse pulmonary changes after cardiopulmonary bypass. ⋯ Dopamine reversed the complex detrimental lung mechanical changes induced by cardiopulmonary bypass and alleviated ventilation heterogeneities without affecting the physiologic deadspace or intrapulmonary shunt. Therefore, dopamine has a potential benefit on the gas exchange abnormalities after weaning from cardiopulmonary bypass.

Blood Products, Crystalloids, and Rapid Infusion: An Experimental Study With Magnesium.
Calcium and magnesium are concentration-dependent pro- and anticoagulant cofactors, and magnesium behaves similarly to calcium in the presence of citrate. The authors hypothesized that magnesium can cause clot formation (primary objective) when mixed with coagulation factor-containing blood products diluted with different crystalloids in a rapid- infuser reservoir. A secondary objective was the observation of any infuser alarms and stops in the event of clotting. ⋯ The addition of magnesium to a combination of LR with coagulation factor- containing blood products consistently resulted in a visible blood clot in the rapid-infuser reservoir in the authors' experimental setup. In addition to MgSO4 1 g in the control, NS, and PL experiments, CaCl2 is needed before a clot can be observed.

Right Ventricular Function After Minimally Invasive Mitral Valve Surgery.
Right ventricular (RV) dysfunction is a significant cause of morbidity and mortality after cardiac surgery. Minimally invasive mitral valve surgery (MIMVS) increasingly is being performed. The authors aim was to evaluate postoperative RV function in patients who underwent MIMVS versus traditional mitral valve surgery. ⋯ The authors study showed that the surgical strategy had no significant impact on postoperative RV function after mitral valve surgery.
