background: liver ischemic insults are important sources of liver injuries leading to production of reactive oxygen species (ros) and mediating liver cell injury. glutathione mediated mechanisms are among the most important defense mechanisms of the liver; n-acetylcysteine (nac) provides cysteine for glutathione defense mechanisms. patients undergoing cardiac surgery are at increased risk of li...

RATIONALE High take-off of the coronary arteries is a rare cardiac anatomic anomaly, which may occur independently or with other congenital heart defects. In the clinical setting, it is noteworthy as a cause of sudden cardiac death. Further, it is vital to identify such anomalies to avoid intraoperative catastrophes in surgeries for congenital heart defects. PATIENT CONCERNS A II/6 systolic h...

Surgical revascularization of the heart (CABG - coronary artery bypass grafting) is one way of treating coronary heart disease. Bleeding is one of the serious and frequent complications of heart surgery and can result in increased mortality and morbidity. Hemostasis disorder may be secondary consequences of surgical bleeding, preoperative anticoagulant therapy, and the use of cardiopulmonary by...

OBJECTIVE To study the prevalence and severity of hyperglycemia in nondiabetic patients undergoing cardiac operation. METHODS In an observational prospective study, 282 non-diabetic patients underwent elective off-pump (n=101) or on-pump (n=181) coronary artery bypass grafting (CABG) surgery from March 2006 to July 2007 in Madani Heart Hospital, Tabriz, Iran. Blood glucose (BG) levels were me...

Although preoperative autologous blood donation is employed in elective surgery, this is declining because of the increasingly safe allogeneic blood supply. However, it continues to be used because of the public's perception of allogeneic blood risks and increasing blood shortages. Patients may donate a unit of blood (450 +/- 45 ml) as often as twice weekly, up to 72 hours before surgery. Preop...

BACKGROUND The aim of this investigation was to assess the incidence of elevated N-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP) and its relation to outcome defined as perioperative adverse cardiac events and all-cause mortality in high-risk patients undergoing non-elective surgery for hip fracture. METHODS A cohort of patients with hip fractures were extracted from a prospe...

introduction: elective upper and lower gi endoscopy is usually performed in children on an outpatient basis with the child under sedation or general anesthesia (ga). the objective of this study was to describe anesthesia related complications in   children undergoing elective gi endoscopy.   materials and methods: the study design was descriptive on 1388 patients undergoing elective gi endoscop...
