[Research Presentation] Purpose: The main purpose of this study is to find out the critical successful factors of weaning from long-term mechanical ventilation support in Taiwan. Method: A prospective study design was conducted from June 2003 to February 2004, in which we collected the patients with mechanical ventilation in the respiratory care center of a medical center in Taipei city. A total of 90 cases that met the selection criteria (had been ventilator dependent for over 7 days) were recruited in the study. Those who were able to wean from mechanical ventilation (disconnected > 48hours) were coined "success group", and those could not were in "failure group". Data were collected by a standard structured questionnaire, and measured respiratory physiology parameters. Data were analyzed using percentage, mean, standard deviation, frequency, t-test, Chi-Square, and ROC curve evaluation. Results: Fifty-four patients (60%) were liberated from ventilator successfully. The minute ventilation (VE), peak expiratory flow (PEF), tidal volume (VT), Hemoglobin were significantly higher in patients who successfully weaned (p<.05), and spontaneous respiratory rate, blood urea nitrogen (BUN), AST and rapid shallow of breath index (RSBI) were lower (p<.05). According to ROC curve evaluation, PEF, Hemoglobin and VE had more efficacy to predicted the prognosis. Conclusions: This study revealed that PEF, Hemoglobin and VE were the most important factors related to successful weaning from ventilator for patients with long-term mechanical ventilation support in Taiwan.
