[Incidence of pulmonary aspiration with different kinds of artificial airways].
A patient with an artificial airway in place, pulmonary aspiration is a serious complication. A prospective study was conducted to investigate the incidence of pulmonary aspiration in patients with all kinds of modern artificial airways with high-volume low-pressure cuffs. In ICU and NSCU (neurosurgery care unit), 40 patients with a tracheostomy or endotracheal tube were included. ⋯ With tracheostomy tubes, 5 of 20 episodes showed positive result (5/20). The difference of incidence between these 2 groups was statistically significant (p less than 0.01). Some possible contributing factors were evaluated between positive and negative episodes, including age, sex, respiration rate, different brands of tracheostomy tubes, modes of ventilation, PEEP level, cuff pressure, nasogastric tubes, coma scale, posture, and ratio of tube and tracheal diameters in tracheostomy group.(ABSTRACT TRUNCATED AT 250 WORDS)
