global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...

background: shigella spp. are gram negative bacteria, which are of global public health importance. the growing of multidrug-resistant shigella isolates are a major problemaround the world. methods: overall, 50 isolates of shigella spp. from children diarrheic stools were studied. the isolates were identified and confirmed using biochemical, serological and molecular methods (ipah, wbgz and rfc...

acute respiratory distress syndrome (ards) is a potential complication of cardiac surgery, given that patients undergoing cabg frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. thus, ards criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. we aimed to investigate frequency of rapid ons...

the most common type of arrhythmia following coronary artery bypass graft (cabg) is atrial fibrillation (af) with an incidence rate of 20-30%. pericardial effusion is one of the etiologic factors of atrial fibrillation occurring after cabg. posterior pericardiotomy (pp) causes the drainage of blood and fluids from the pericardial space into the pleural space leading to a decreased pericardial e...

the duration of icu (intensive care unit) stay in cardiac surgery patients has an important role in the rate of complications and costs. the aim of this study was to determine the role of perioperative risk factors in clinical outcome based on the time of icu discharge. in this descriptive study, 219 patients undergoing off-pump coronary artery bypass (opcab) surgery in afshar hospital in yazd,...

conclusion these data show that the identified gene encoded tet resistance gene as mfs–type multi-substrate efflux transporter, which contributes to intrinsic resistance on range of structurally unrelated compounds in salmonella species. background tetracyclines (tcs) are a type of broad-spectrum bacteriostatic antibiotics used for treatment of a wide variety of infections. these antibiotics ev...

gastro-esophageal reflux disease (gerd) regularly occurs when stomach acid moves up from the stomach into the esophagus. gerd might be associated with chronic asthma symptoms such as coughing and breathlessness. according to several studies on children and adults, gerd is proven to have a close relationship with asthma.  medication treatment via proton-pump inhibitors (ppis), such as omeprazole,...

introduction: insome cases, assist devices are required to ensure an adequate cardiac output after cardiac surgery. intra-aortic balloon pump (iabp) is the most commonly used cardiac assist device, which provides first-line support for patients with heart failure. the aim of this study was to determine factors affecting the mortality rate of patients receiving iabp. materials & methods:  in thi...

OBJECTIVES To evaluate the cerebral and myocardial protective effects of hyperbaric oxygen preconditioning in both on-pump and off-pump coronary artery bypass graft surgery. DESIGN A prospective, randomized, single-blinded study including patients scheduled for elective on-pump or off-pump surgery between December 2007 and February 2009. SETTING A tertiary care university teaching hospital....
