Percutaneous dilatational tracheostomy and surgically created thracheostomy in ICU patients.
Following advances of Intensive Care medicine and widespread administration of mechanical ventilation, tracheostomy has become one of the indispensable surgical procedures. During this research we tried to assess and compare two main strategies for doing tracheostomy: Surgically Created Tracheostomy (SCT) and Percutaneous Dilatational Tracheostomy (PDT). ⋯ According to the results of our study and similar researches, it can be concluded that PDT can be considered as the preferred procedure in cautiously selected patients during their ICU stay.

Arterial lactate level changes in first day after cardiac operation.
Lactate level is an important index for predicting cardiac events. There are some debates about time and type of sampling for defining of its prognostic values. ⋯ Persistent high level (>4 mmol/L) will occur unusually at 24(th) hour but can be associated with poor prognosis. Serial measurement of serum lactate level can be helpful for our management quality and very highly persistent arterial lactate level (>4 mmol/lit) up to 24 hours after operation will increase mortality rate in operated patients for congenital heart disease.

Evaluation of the prevalence and risk factors of delirium in cardiac surgery ICU.
Delirium is defined as an acute cognitive disorder presenting with fluctuation in cognition, apathy and non-organized thinking. It may increase morbidity, mortality, ICU stay and cost. In patients who underwent heart surgery delirium may increase post-operative complications such as respiratory insufficiency, sternum instability and need to re-operation of the sternum. The aim of this study was to evaluate the prevalence and risk factors of delirium in patients admitted to cardiac surgery. ⋯ Older Age, CPB, history of CVA, Atrial Fibrillation, and prolonged mechanical ventilation are considered as the risk factors of delirium in cardiac surgery patients.

Postoperative Atrial Fibrillation following Open Cardiac Surgery: Predisposing Factors and Complications.
New-onset postoperative atrial fibrillation (POAF) is a common complication of cardiac surgery that has substantial effects on outcomes. The aim of this study is to analyze the risk factors in the pre, intra, and postoperative periods, and evaluate its impact on patients' outcome. ⋯ POAF is the most common arrhythmia after cardiac surgery and not only concerted effort should be performed to identify and to reduce the risk factors, but also effective treatment is necessary to prevent mortality and morbidity.

Alterations in Circulating Adhesion Molecules in Acute Myocardial Infarction before and after Thrombolysis with Streptokinase.
The role of adhesion molecules in the development and progression of coronary atherosclerosis is inevitable. It is not clear yet whether these molecules increase or decrease in level after thrombolytic therapy. This study was designed to compare concentrations of soluble forms of adhesion molecules in patients with acute myocardial infarction before and after reperfusion by thrombolysis with streptokinase (SK). ⋯ Adhesion molecules which mediate the interactions in leukocyte endothelium vary in levels after reperfusion with SK. It was shown that 4 out of 6 adhesion molecules significantly reduced after thrombolysis with SK.
