Sažetak
Background: During mechanical ventilation the endotracheal tube (ETT) cuff pressure should be maintained in the range of 20-30 cmH₂O to prevent ETT - related complications. ETT - cuff underinflation increases the risk of aspiration of oropharyngeal secretions and air leakage, while overinflation increases the risk of tracheal wall damage.Aims: To assess the impact of changes in body position and routine intensive care unit (ICU) procedures (endotracheal suctioning and bronchoscopy) on ETT - cuff pressure.Methods: Twelve critically ill adult patients were included in the study. All patients were orally intubated and mechanicaly ventilated by pressure controle mode. Cuff pressure was set to 25 cmH₂O in each patient while in neutral position (supine, head of the bed elevated to 40o). Cuff pressures were measured after right and left lateral patient positioning, closed endotracheal suctioning and bronchoscopy.Results: The cuff pressure, on average, decreased after right and left lateral patient positioning by 7.83 (p<0.001) and 6.92 cmH₂0 (p<0.001), respectively. The avarage cuff pressure decreased by 5.75 cmH₂O (p<0.001) after closed endotracheal suctioning, and by 7.42 cmH₂O (p<0.001) after bronchoscopy. 41.7 % of measurement were below 20 cmH₂O.Conclusions: Routine ICU procedures and changes of body positions significantly impact the ETT cuff pressure in patients receiving mechanical ventilation. To reduce ETT – related complications, cuff pressure measurement should be performed after every procedure. To maintain cuff pressure in the optimal range, the continuous endotracheal cuff pressure control system could be used.
