The effect of endotracheal suctioning with and without normal saline on hemodynamic and respiratory parameters in patients with mechanical ventilation in intensive care unit , rasht,guilan

Endotracheal suctioning is common nursing care in intubated patients . nurses commonly instillation normal saline before suctioning procedure . the purpose of instillation N/S is diluting and loosening thick secretions and facilating moblisation and remove secretions.however , its efficacy is unsupported by research based evidence .this study is a randomized , , cross-over , clinical trial , done on 74 intubated patients that recive mechanical ventilation,and their hemodynamic ststus is stable.we lay aside patients had chronic disease and those using cardiac and respiratory medications; using muscle relaxtion medications or change setting ventilator within our study and patients that do not require suctioning after 2 hrs. the purpose of this research is to be determin to be affected with each of the method on patients. in the first cycle of study , patients randomly assigned two group. group A ( suctioning without N/S) group B (suctioning with instilation 5 cc N/S ) , then respiratory and hemodynamic parameters meassure once befoer suctioning and another after suctioning .the next cycle ., rested for 2 hrs, and using cross-over design. two group of patients is interchange.again the whole procedure repeat .
