Predictive value of diaphragm rapid shallow breathing index combined with maximum inspiratory pressure in withdrawl of me-chanical ventilation
Objective To investigate the predictive value of diaphragmatic shallow fast breathing index(D-RSBI)combined with maximum inspiratory pressure inspiratory pressure(MIP)for withdrawal of mechanical ventilation.Methods Sixty-eight patients admitted in ICU of Pinghu First People's Hospital from September 2022 to September 2023 who underwent spontaneous breathing trial(SBT)for withdrawl of mechanical ventilation were included in the study.Diaphragmatic displacement and MIP were measured after 30 minutes of SBT,and the respiratory rate was recorded for calculating D-RSBI.Patients were divided into extubation success group and extubation failure group based on extubation outcome.The predictive efficacy of D-RSBI,MIP,and their combination for extubation outcome was evaluated using ROC curves.Results Among the 68 patients,18 cases(26.47％)failed extubation,while 50 cases(72.53％)succeeded.The extubation failure group had higher respiratory rate,D-RSBI,and lower diaphragmatic displacement and MIP than those in the extubation success group(all P＜0.05).ROC curve analysis showed that the combination of D-RSBI with MIP had a higher predictive value for successful outcomes of extubation(AUC=0.933)than D-RSBI(0.759)or MIP(0.899)alone,and the specificity of the combined prediction was higher than that of single index.Conclusion Both D-RSBI and MIP have good predictive value for withdrawl of mechanical ventilation in ICU patients,while their combination has a even better prediction efficacy.
