Table 1 The relationship between the presence or absence of post-operative airway stenosis symptoms and cuff pressure
The number of times the cuff pressure became 30 cmH2O or higher (times) | The ratio to operation time the cuff pressure became 30 cmH2O or higher (%) | |
|---|---|---|
With airway stenosis symptoms (n = 5) | 55 (32–92) | 40 (16–80) |
Without airway stenosis symptoms (n = 56) | 48 (29–68) | 40 (28–66) |
P value | 0.7523 | 0.9057 |
