  • Beschreibung: BACKGROUNDEndotracheal tube suctioning is necessary for patients receiving mechanical ventilation. Studies examining saline instillation before suctioning have demonstrated mixed results.METHODSA prospective study to evaluate whether saline instillation is associated with an increased risk of suctioning-related adverse events in patients 18 years old or younger requiring mechanical ventilation through an endotracheal tube for at least 48 hours when suctioned per protocol using a bedside decision tree.RESULTSA total of 1986 suctioning episodes (1003 with saline) were recorded in 69 patients. The most common indication for use of saline was thick secretions (87% of episodes). In 586 suctioning episodes, at least 1 adverse event occurred with increased frequency in the saline group (P < .001). Normal saline was more likely to be associated with hemodynamic instability (P = .04), bronchospasm (P < .001), and oxygen desaturation (P < .001). Patient factors associated with adverse events include younger age (P < .001), a cuffed endotracheal tube (P = .001), endotracheal tube diameter of 4.0 mm or less (P < .001), respiratory or hemodynamic indication for intubation (P < .001), underlying respiratory disease (P < .001), and longer duration of mechanical ventilation (P < .001). Saline instillation (P < .001), endotracheal tube size of 4.0 mm or less (P = .03), and comorbid respiratory diseases (P = .03) were associated with an increased risk of adverse events.CONCLUSIONSSaline instillation before endotracheal tube suctioning is associated with hemodynamic instability, bronchospasm, and transient hypoxemia. Saline should be used cautiously, especially in children with a small endotracheal tube and comorbid respiratory disease.
