At acute hospitals, self-removal and/or accidental removal of tubes are among major adverse events. In addition to causing preventable pain or prolonging hospital stay, self-extubation of tracheal tubes might cause hypoxic encephalopathy and endanger the patient's life. The development of a self-removal risk assessment tool is needed to prevent self-removable of tubes. We conducted a literature survey to identify risk factors for extubation of tracheal tubes.
We identified and reviewed 61 studies regarding extubations of tracheal tubes using PubMed and Ichushi. These included 18 observational studies with controls, 8 cohort studies and 10 case control studies, which were used in this study for their high reliability. Elevated blood urea nitrogen, restless or agitation, weaning and nosocomial infection were identified as risk factors of extubation. No risk assessment tool was verified and approved widely.Risk factor identification using reliable research design and development of risk assessment tool seem necessary to prevent extubation effectively.
