patients and methods this retrospective study used a database of a cr ward of a hospital in iran. the demographic and clinical information of 574 patients participating in the cr program from april 2005 through april 2010 were analyzed. in order to determine the predictors of anxiety, binary logistic regression was performed. results after adjustment for gender, age and education, the results s...

Using a novel noninvasive, visible-light optical diffusion oximeter (T-Stat VLS Tissue Oximeter; Spectros Corporation, Portola Valley, CA) to measure the tissue oxygen saturation (StO2) of the buccal mucosa, the correlation between StOz and central venous oxygen saturation (ScvO2) was examined in children with congenital cyanotic heart disease undergoing a cardiac surgical procedure. Paired StO...

This study included U.S. Medicare patients who underwent major cardiac, vascular, gastro-intestinal and orthopedic surgical procedures in 2011. Using the CMS Inpatient Standard Analytical Files with 100% of claims for Medicare fee-forservice beneficiaries, patients were identified based on principal ICD-9-CM procedure code on the claim. Overall, 63 procedures codes in four categories (cardiac, ...

The recent widespread popularity of spinal anesthesia can be traced to two events. One is the appreciation that, when used for operations below the level of the umbilicus, anesthetically induced physiologic trespass is less with spinal than with general anesthesia. The other is the recognition that modest hypotension with peripheral vasodilation, that may be seen with spinal anesthesia or intra...

Hemodynamic instability is the major concern in surgical patients with pericardial diseases, since general anesthesia and positive pressure ventilation may precipitate cardiac tamponade. In advanced constriction diastolic impairment and myocardial fibrosis/atrophy may cause low cardiac output during and after surgery. Elective surgery should be postponed in unstable patients with pericardial co...

Our cardiac surgical program performs 1,200 cardiopulmonary bypass (CPB) procedures annually with approximately 100120 [50% of patients who present with atrial fibrillation (AF)] of these patients undergoing an AF surgical ablation (SA) procedure concomitant to their cardiac surgical operation. Furthermore, we also perform stand-alone surgical ablation for AF as an isolated procedure for patien...

of time the influence of matter on life and mind will gradually become obliterated and replaced by the influence of mind and its transcendent successors in the great steps of creative evolution." Therefore, "the remote successors of man may be free and independent of matter with infinite possibilities of future progress notwithstanding the complete dissolution of the universe." Pure thought, th...

BACKGROUND Dental extraction of abscessed or infected teeth before cardiac operation is often performed to decrease perioperative infection and late endocarditis. Literature to support dental extraction before cardiac operation is limited. The goal of this study was to evaluate the risk of major adverse outcomes in patients undergoing dental extraction before cardiovascular surgical procedures....

Background Frailty assessment may inform surgical risk and prognosis not captured by conventional surgical risk scores. Purpose To evaluate the evidence for various frailty instruments used to predict mortality, functional status, or major adverse cardiovascular and cerebrovascular events (MACCEs) in older adults undergoing cardiac surgical procedures. Data Sources MEDLINE and EMBASE (witho...

The goal of hyptensive anesthesia is the safe reduction of intraoperative blood loss, thus reducing transfusion risks.  Previous hypotensive technics had a narrow margin of safety in that cardiac output was usually reduced in proportion to the degree of induced hypotension. This is in contrast to the results of our study, in which Sodium Nitroprusside was used as the sole hypotensive agent. Ni...
