Background & aim: weaning of ventilator-dependent patients has always been associated with serious and risky challenges. Some measurable categories exist that predict the consequences of weaning. Due to the multiplicity of these categories, the researchers of this study decided to conduct a study to identify the most important categories in the patient's readiness for weaning from the ventilator and its consequences.
Methods: In this cross-sectional study, 96 ventilator-dependent patients were included randomly. Patient`s respiratory criteria and physiological parameters were measured in three time intervals. Patients were divided in two, successful and unsuccessful of weaning groups. By following each of the respiratory and physiological criteria and using regression test statistics and plotting the rock curve, the power of each of the above criteria in predicting the weaning consequences were plotted.
Results: The Odds Ratio (OR) for failure in weaning increases with increasing Rapid Shallow Breathing Index (RSBI) at all three time intervalss. Also, the results showed that the criteria of RSBI before taking out the endotracheal tube with a sensitivity of 73% and a specificity of 88% and a surface below the curve of 0.82 in comparison with other criterions had the greatest effect in predicting failure in weaning.
Conclusion: Among the clinical criteria available to assess the probability of failure in the weaning, compared to other criteria, RSBI has a better sensitivity and specificity. |
