Left ventricular diastolic dysfunction plays an important role in congestive heart failure. Although once thought to be lower, the mortality of diastolic heart failure may be as high as that of systolic heart failure. Diastolic heart failure is a clinical syndrome characterized by signs and symptoms of heart failure with preserved ejection fraction (0.50)(More)
General anesthesia requires managing a complex array of anesthetic agents that act on an intricate web of neural connections or neural nexus. Both inhaled and intravenous anesthetics must intervene at some level of the neural nexus that provides for amnesia, immobility, hypnosis, and suppression of noxious reflexes. These interactions occur at the spinal(More)
Like the windbag of a bagpipe, the functional residual capacity (FRC) is the lung volume that acts as a reservoir of air for physiologic use. This reserve volume is particularly important during the period of apnea that occurs during induction of general anesthesia. The balance of the inward elastic recoil of the lung and the outward chest wall forces(More)
Left ventricular diastolic function plays an important role in cardiac physiology. Lusitropy, the ability of the cardiac myocytes to relax, is affected by both biochemical events within the myocyte and biomechanical events in the left ventricle. Beta-adrenergic stimulation alters diastole by enhancing the phosphorylation of phospholamban, a substrate within(More)
Seizures are common neurologic complications of cancer and can occur at any point in the disease trajectory. Despite this, the exact pathophysiologic basis of seizures related to cancer is not known. The etiology of seizures is thought to be multifactorial, including the presence of tumors within the cranial cavity, metabolic derangements, and the direct(More)
