The Correlation between Psychophysiological Factors and Ventilator Weaning in Mechanical Ventilated Patients in Taiwan
摘要
Contemporary studies related to mechanical ventilation weaning are typically more focused on exploring physiological weaning predictors than psychological weaning predictors. The purpose of this study was to explore correlations among psychophysiological factors of fear, state anxiety, dyspnea, and rapid shallow breathing index (RSBI) and the weaning outcome in mechanical ventilated patients. This was a prospective study. There were104 subjects recruited from intensive care units (ICUs) of a medical center in Taipei, June 2007 to June 2008. These subjects were asked how they were feeling of fear, state anxiety, and dyspnea at the time of ventilator weaning by responding to state anxiety inventory and numerical rating scales. The data of rapid shallow breathing index, minute ventilation, and the length of mechanical ventilation were measured by ventilation monitor (ventcheck) and follow-up recorded, respectively. 103 out of 104 subjects completed the participation in this study. Subjects' emotional fear (4.6±3.5) and cognitive fear (3.0±2.9) significantly correlated with their anxiety (4.5±3.3) and dyspnea (3.7±2.8) (p＜0.05). A positive correlation was found between subjects’ anxiety and dyspnea (r = 0.329, p＜0.05), but there was insignificant correlation between their anxiety and RSBI (p＞0.05), or their anxiety and LOMV (p＞0.05). The level of subjects’ dyspnea significantly correlated with their RSBI (r = 0.198, p＜0.05). RSBI was the only one index to predict the LOMV (r = 0.275, p ＜0.05). Subjects’ psychological factors of fear and anxiety did not have significant correlations with their length of mechanical ventilation, but did have significantly positive correlation with dyspnea. However, dyspnea did have a significant correlation with RSBI, which was the most powerful predictor of the length of mechanical ventilation. Results from this study provide a direction for health care providers to consider when managing the care of mechanical ventilated patients.
