The aim of this study was to investigate the effect of various patients' positions on endotracheal tube cuff pressure after adult cardiac s...

Background Cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. The aim of this study was to compare the effects of modified ultrafiltration (MUF) versus conventional ultrafiltration (CUF) on duration of mechanical ventilation and hemodynamic status in chi...

Background: One of the adverse effects following cardiac surgery is cognitive dysfunction. The prevalence of cognitive dysfunction after heart surgery is reportedly 30% - 80%. Objective: The purpose of this study was to evaluate the prevalence and risk factors of cognitive dysfunction in the ICU after heart surgery. Methods: In this observational s...

Background: Detecting pain is crucial in sedated and mechanically ventilated patients, as they are unable to communicate verbally. Objectives: This study aimed to compare Bispectral index (BIS) monitoring with the Critical-care pain observation tool (CPOT) and vital signs for pain assessment during painful procedures in intubated adult patients...

Background: Invasive and continuous blood pressure (BP) monitoring is crucial after cardiac surgery. Accuracy of BP measurement mostly depends on patency of arterial catheter and acceptable waveform. Heparinized saline flush usually used for this purpose may be accompanied by potential heparin adverse effects. Objectives: The aim of this study w...

Background: After major surgeries, such as abdominal or thoracic surgery, the majority of patients experience moderate to severe pain that may not be optimally controlled. Inadequate pain relief may lead to complications that can hinder rehabilitation and slow recovery.

Background: Heparinized saline solution is used to prevent occlusion in the arterial catheters and central venous pressure monitoring catheters. Even at low dose, heparin administration can be associated with serious complications. Normal saline solution can maintain patency of arterial catheters and central venous pressure monitoring catheters....
