Abstract
Purpose: The purpose of this study was to investigate the sleep patterns and the factors related to sleep disturbance in mechanically ventilated patients in intensive care units (ICUs). Sleep patterns in this study included both quality and quantity of sleep. Methods: Forty-four subjects were recruited in ICUs at a tertiary university hospital in D city. Data were collected using questionnaires, observation, and medical record from June, 2008 to May, 2009. Results: The total mean of sleep quality was $1.99{\pm}1.68$. The mean of total sleep time per 24-hour period was $3.75{\pm}1.94$hour (range 1-7.25) in mechanically ventilated ICU patients. The main sleep disturbance factors were listed as frequent nursing activities, attachment of medical appliances, and noise. All these factors were also significantly related to the sleep quality. Conclusion: These results indicated that mechanically ventilated patients were both qualitatively and quantitatively deprived of sleep far more than other ICU patients. In summary, a deeper understanding of sleep characteristics in mechanically ventilated ICU patients could help nurses to improve sleep derangements and patient outcome.
