Among the 109 subjects who were never physically restrained during their ICU stay, 18 had an unplanned extubation. Background information was
compared between patients in the unplanned extubation group and patients in the control group in an effort to identify factors contributing to unplanned extubation if the subjects were not physically restrained (Table 3, lower section).
Although the unplanned extubation group and the control group had no significant differences in age, APACHE II scores, route of intubation, rates of nosocomial infection, or sedative status, the unplanned extubation group had higher GCS scores on ICU admission
