Thoracic epidurals in heart valve surgery: neurologic risk evaluation.
To evaluate the risk of neurologic complications resulting from epidural hematoma in a series of patients who had surgery for repair or replacement of heart valves under combined general and thoracic epidural anesthesia (TEA). ⋯ TEA can provide effective postoperative analgesia and assist in early tracheal extubation in cardiac valve surgery. In this series, there were no neurologic deficits detected. When certain safety measures are taken, routine TEA is feasible and helpful in cardiac valve surgery.

Time course of neuromuscular blockade with rocuronium in children with intracardiac shunts.
To evaluate the time course of neuromuscular blockade after rocuronium in children with intracardiac shunts. ⋯ This study shows a more rapid onset of rocuronium in children with cyanotic congenital heart disease. In these patients, rocuronium is indicated, particularly for rapid airway control.

Validation of continuous thermodilution cardiac output in patients implanted with a left ventricular assist device.
To assess the accuracy of a continuous cardiac output (CCO) monitor against an independent, intravascular measurement of flow as can be performed in patients fitted with a left ventricular assist device (LVAD). ⋯ The data indicate that the CCO system tends to overestimate cardiac output by approximately 500 mL/min when compared with LVAD flow. Nevertheless, this bias is within the range found by other less-invasive studies done to assess the accuracy of this system and further serves to confirm its relative accuracy.

Randomized Controlled Trial Clinical TrialCentrifugal versus roller head pumps for cardiopulmonary bypass: effect on early neuropsychologic outcomes after coronary artery surgery.
To test the hypothesis that routine use of a centrifugal pump in the cardiopulmonary bypass circuit would result in a lower incidence of early neuropsychologic deficit when compared with conventional roller pumps. ⋯ There was no significant difference in the incidence of neuropsychologic deficit postoperatively with routine use of centrifugal pumps. The larger number of individual test deficits in the roller pump group suggest that further studies to assess the potential neuropsychologic benefits of the use of centrifugal pumps are warranted.
