and infection rates did not differ significantly between
the unplanned extubation group and the control group
if the subjects were not physically restrained (Table 3).
These results indicate that physically restrained patients
with nosocomial infection and patients with better
neurological status who are not physically restrained
are most at risk for unplanned extubation. In other
words, the risk of unplanned extubation can be due
to the use of physical restraints and the presence of
nosocomial infection.
