Abstract
Aim: The aim of this study is to compare between the efficacy of some predictors in different weaning modes
comparison between different indices as regard weaning success and failure
Method: The study was carried out on 100 (70 males,30 females) patients receiving mechanical ventilation ,due to respiratory and non respiratory causes. Patients were divided into 4 groups according to the method of weaning: group (1) CPAP (n = 25), group (2) PSV (n = 25), group (3) SIMV (n = 25) and group (4) NPPV (n = 25). We used a 3 steps protocol for weaning according to Cleveland Clinical Journal of Medicine.
Results: the highest successes rate is in the NPPV group (92%) while the highest failure rate is in the SIMV group (36%). After starting weaning the highest value of PaO2, PaCO2, and PH was in the NIPPV group and the lowest value was in the SIMV group. There is highly significant difference (P value < 0.001) between patient who succeeded and who failed weaning as regard CORE index and only significant difference regarding RSBI , while there is non significant difference as regard other indices(CROP,IWI).
Conclusion: ABG and RSBI can be used as good weaning predictors and the CORE index is better in predicting the weaning outcome than the CROP index, the IWI and the RSBI.
Comparison between the studied groups as regards traditional parameters measured during weaning.
