| Objective: To explore the value of diaphragmatic ultrasound in predicting the outcome of the tracheostomy tube capping trials in patients with severe neuropathy in rehabilitation department. Methods: A total of 48 patients with severe neuropathy who were scheduled to undergo the tracheostomy tube capping trials were selected. Before the trials, the diaphragm excursion (DE), diaphragm thickness at end inspiratory (DTei), diaphragm thickness at end expiratory (DTee), inspiratory time and other diaphragm indicators were measured, and excursion-time (E-T) index was calculated. Based on the results of the trials, the patients were divided into two groups: 31 patients in the successful group and 17 patients in the failure group. A comparison of the diaphragm indexes between the two groups was conducted, and the receiver operating characteristic (ROC) curve was established to analyze the predictive value of potential diaphragm ultrasound indexes for the successful outcome of the tracheostomy tube capping trials. Results: The DTF and E-T indexes in the successful group were higher than those in the failure group (P<0.05). The AUC of DTF and E-T index for predicting the successful outcome of the tracheostomy tube capping trials was 0.769 and 0.738, respectively. The combined predictive value of the two indexes was higher, with an AUC of 0.793, a sensitivity of 80.6%, and a specificity of 70.6%. Conclusion: DTF and E-T index can be used to predict the successful outcome of the tracheostomy tube capping trials, and the combined prediction value of the two is superior to a single parameter. |
