Risk Factors for Unplanned Extubation
Among the 191 patients who were physically restrained, 82 had an unplanned extubation. Background information was compared between patients in the unplanned extubation group and patients in the control group to identify the factors contributing to unplanned extubation (Table 3, upper section). Age, APACHE II scores, GCS score, restraint method, route of intubation, and sedative status did not differ significantly between the unplanned extubation
and control groups. However, the unplanned extubation group had a higher rate of nosocomial
infection than did the control group (29.3% vs 15.6%, P = .02).
