BACKGROUND Contrast-induced nephropathy (CIN) remains a common complication of radiographic procedures. Radiocontrast agents can cause a reduction in renal function that may be due to reactive oxygen species. Conflicting evidence suggests that administration of antioxidants prevents CIN. METHODS We assessed the efficacy of allopurinol in preventing CIN.(More)
Although uric acid (UA) is considered as an antioxidant, the relationship between serum UA levels and cardiovascular diseases is not clear yet. Higher brachial artery resting diameter (BD), impaired brachial artery flow-mediated dilatation (FMD), increased carotid intima-media thickness (IMT), decreased aortic distensibility (AoD), and increased aortic(More)
BACKGROUND We investigated whether isovolumic acceleration (IVA) under inotropic stimulation as a means of right ventricular (RV) contractile reserve, is a surrogate for hemodynamic burden and has prognostic value in patients with mitral stenosis (MS). METHODS Thirty-one pure MS patients and 20 controls underwent cardiac catheterization, exercise test,(More)
OBJECTIVES When added to local anaesthetics, dexamethasone can prolong the duration of peripheral blocks. Dexamethasone has a long and efficient glucocorticoid structure and presents anti-inflammatory properties. The aim of this study was to determine the effect of dexamethasone on the block duration added to levobupivacaine used for transversus abdominis(More)
BACKGROUND The gynecological laparoscopic surgery requires pneumoperitoneum (PP) with CO2 gas insufflation. CO2 PP may influence cardiac automic function (CAF). This study was conducted to assess its significance and the prolonged effects of CO2 PP on the activity of the cardiac autonomic function 24 hours after the operation by heart rate turbulence (HRT)(More)
Elevated serum bilirubin concentrations protect from atherosclerotic diseases; however,it is not clear whether higher serum bilirubin concentrations in physiological ranges do the same. To investigate the association of high and low serum bilirubin concentrations with left ventricular diastolic function and aortic elastic properties.We evaluated left(More)
BACKGROUND The aim of this study was to investigate the effect of spinal anesthesia (SA) on olfactory memory using Brief-Smell Identification TestTM (B-SIT). PATIENTS AND METHODS This, prospective, clinical study was performed on 40 ASA physical status I-III patients, between 18-65 years of age undergoing a planned elective minor surgery under SA. All(More)
Low levels of magnesium (Mg) are associated with chronic inflammatory stress. Some animal studies have reported that a moderate deficiency of Mg, similar to that which occurs in humans, may increase inflammatory or oxidative stress stimulated by other factors, such as disrupted sleep or sleep deficiency. This cross-sectional study evaluated the relationship(More)
BACKGROUND The aim of this study was to investigate the effect of magnesium administered before induction on the hemodynamic response and QT dispersion (QTd) related with intubation in hypertensive patients and to compare it with lidocaine. METHODS Patients with essential hypertension who were under ≤ 65 years old, scheduled for elective surgery with a(More)
