Comparison of Success Rate of Weaning from Mechanical Ventilation Using Burn’s Wean Assessment Program and Routine Method

Abstract

Background and Objectives: Weaning decision for the patients undergoing mechanical ventilation (MV) is often made based on personal judgments and experiences, which results in longer MV length of stay and higher costs. Therefore, the present study aimed to evaluate the effect of Burn’s wean assessment program on the success rate of weaning from ventilator in patients admitted to the Intensive care unit (ICU). Methods: The present experimental study was carried out on 100 patients undergoing MV for more than 72 hours. The patients were selected by convenience sampling and randomly divided into two groups of 50 subjects. Burn’s wean assessment program was applied to the intervention group, while weaning was assessed by a physician in the control group. Results: 35 patients in the intervention group were male and 15 were female. In the control group, 36 were male and 14 were female. Chi-square test showed no statistically significant difference between the two groups (P < 0.826). In the intervention group, 46 patients had successful weaning (92%) and 4 patients had unsuccessful weaning (8%). In the control group, 35 patients had successful weaning (70%) and 15 patients had unsuccessful weaning (30%). Chi-square test showed a statistically significant difference between the two groups (P < 0.005). Conclusions: Using Burn’s scale for assessing patient readiness for weaning from mechanical ventilation is more useful.
