The relationship between a person's height and appropriate endotracheal tube length.
The relationship between a person's height and the dimensions of that person's upper airways has been studied in adult subjects. Using this relationship, formulae have been derived which predict appropriate lengths for endotracheal tubes. The formulae are as follows: 1. ⋯ Orotracheal tube (teeth to mid-point of trachea + 3 cm) = Subject height (cm)/10 + 5 3. Nasotracheal tube (external naris to mid-point of trachea) = Subject height (cm)/10 + 8 These formulae are not foolproof but provide a useful working guide. All usual comfirmatory tests of correct placement should be employed.

An investigation was conducted to determine the overall incidence and reasons for extubation and reintubation in a NICU population in order to establish a baseline for ongoing quality assessment and evaluation monitoring. The investigators sought to identify factors associated with accidental extubation for which action plans to improve care could be developed.

[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)
