Abstract
Cuff pressure is essential in endotracheal tube management. Guidelines recommend a cuff pressure of 20 to 30 cm H2O. Subinflation of the cuff puts patients at risk for micro-aspiration of subglottic secretions. This micro-aspiration is considered the major pathogenic mechanism for ventilator-associated pneumonia, complication with marked morbidity and mortality. Aim: This study was carried out to determine the correlation of endotracheal tube cuff pressure and the incidence of ventilator-associated pneumonia. Design: Descriptive research design. Setting: In two critical care units at Assiut Main University Hospital: Trauma ICU and general ICU. Subjects: A convenience sample of 60 critically ill patients. Tools: Three tools were utilized to collect data of study, Tool I: Patient assessment sheet. Tool II: Endotracheal tube cuff pressure measurements. Tool III: Ventilator- associated pneumonia assessment sheet. Method: The researcher used preparatory, implementation and evaluation phases to implement this study. Results: Finding of the present study revealed that there was significant statistical relationship between endotracheal tube cuff pressure and incidence of ventilator associated pneumonia (P value < 0.05). Conclusion: There is a significant statistical relationship between endotracheal tube cuff pressure and incidence of ventilator associated pneumoniaed as a basic part of care provided to all critically ill patients in intensive care units.
