N/A Aspiration is a well recognized source of pulmonary infection. In most clinical situations, however, the actual incidence of aspiration has not been well documented, We investigated the incidence of pulmonary aspiration and the factors affecting aspiration in patients with intubation and tracheostomy. Aspiration was evaluated by applying Evans blue dye to the posterior tongue just after each formula tube feeding for 24 hours. Bluish discoloration and elevated glucose concentration of the material suctioned from the artificial airway were regarded as evidence of aspiration. The results obtained were as follows: 1) The incidence of pulmonary aspiration in patients with intubation or tracheostomy was high (69%), 2) Unconscious patients tended to aspirate frequently, but the presence or absence of ventilatory support, tracheostomy or intubation did not play a significant role in the development of aspiration. 3) There was only a weak correlation between the Evans blue dye test and the glucose oxidase reagent strip method in detecting pulnonary aspiration. In conclusion, the incidence of pulmonary aspiration in patients with intubation and tracheostomy is very high. These findings suggest that even in the case of intubation and tracheostomy, careful observation of pulmonary aspiration is necessary
