Diaphragmatic Rapid Shallow Breathing Index for Predicting Weaning Outcome From Mechanical Ventilation: Comparison With Traditional Rapid Shallow Breathing Index
In Brief
A clinical study evaluating Diaphragm ultrasound for Weaning Failure. Completed, enrolled 106 participants across 1 site.
Detailed Summary
Predicting successful discontinuation from mechanical ventilation has been a focus of interest to all critical care physicians . Various weaning indices have been investigated to optimize the weaning process. Among them, the rapid shallow breathing index (RSBI) has gained wide use but it have different sensitivities and specificities. By substituting tidal volume (VT) with diaphragmatic displacement (DD) in the calculation of RSBI a new index (the diaphragmatic rapid shallow breathing index DRSBI) was proposed and it was independently associated with weaning failure and its accuracy for predicting weaning outcome is expected to be superior to the traditional RSBI.

Interventions
In the semi-sitting position ultrasonography for diaphragmatic displacement was performed by the same intensivist. Diaphragmatic movement was evaluated by using 2 to 5 MHz US probe (Sonosite M-Turbo machine). The right hemidiaphragm was examined by two-dimensional (2D) and M-mode to record diaphragm displacement.in M-mode, the diaphragmatic displacement (cm) was measured and then DRSBI was calculated by respiratory rate (RR)/ diaphragmatic displacement (DD) (in mm)
