Time course of desflurane-induced preconditioning in rabbits.
The authors tested the hypothesis that volatile anesthetic-induced preconditioning (APC) follows a similar time pattern as that described for ischemic preconditioning and that delayed APC is mediated by nitric oxide. ⋯ Desflurane induces a first (0.5-2 hours) and second window of preconditioning (24-72 hours) in the rabbit model of acute myocardial infarction. The second window of APC is mediated by nitric oxide.

Effects of fenoldopam mesylate on central hemodynamics and renal flow in patients undergoing cardiac surgery: color Doppler echocardiographic evaluation.
The purpose of this study was to evaluate the effect of 0.1 microg/kg/min of fenoldopam mesylate on renal flow and central hemodynamics measured by echocardiography in hemodynamically stable patients with preserved renal function undergoing cardiac surgery. ⋯ In hemodynamically stable cardiac surgery patients with preserved renal function, an infusion of 0.1 microg/kg/min of fenoldopam mesylate has no influence on systemic hemodynamics while increasing renal blood flow.

Outcome after implantation of cardiac resynchronization/defibrillation systems in patients with congestive heart failure and left bundle-branch block.
The implantation of cardiac resynchronization/defibrillation devices (CRT-Ds) increasingly is used in patients with congestive heart failure and left bundle-branch block. There are no data on the effects of anesthesia and surgery on outcome after implantation. ⋯ In patients with severely impaired cardiac function, general anesthesia for the implantation of a biventricular pacing device can be used with justifiable risk. The method of anesthesia did not influence outcome.

The year in cardiothoracic and vascular anesthesia: selected highlights from 2009.
The hybrid operating room is the venue for transcatheter therapy with the convergence of 3 specialties: cardiac surgery, cardiovascular anesthesiology, and interventional cardiology. Transcatheter aortic valve replacement is proof that cardiac specialists have embraced the endovascular revolution. Because pharmacologic conditioning and ischemic myocardial conditioning are safe and effective, they are currently the focus of multiple trials. ⋯ Intensive insulin therapy offers no further outcome advantage and significantly increases hypoglycemic risk. The past year has witnessed the advent of a new clinical venue, new devices, and new drugs. The coming year will most likely advance these achievements.

Cardioprotection afforded by St Thomas solution is enhanced by emulsified isoflurane in an isolated heart ischemia reperfusion injury model in rats.
The purpose of this study was to investigate whether adding emulsified isoflurane to St Thomas cardioplegia solution could enhance the cardiac protection after cardioplegic arrest in rats. ⋯ St Thomas cardioplegia solution supplemented with emulsified isoflurane enhanced its cardioprotection in an isolated heart ischemia reperfusion injury model in rats.
