114 P. : charts , facsimiles ; 25cm Background: Ventilator induced diaphragmatic dysfunction (VIDD), as a loss of diaphragmatic force generating capacity due to the use of mechanical ventilation. Difficulties in discontinuing ventilatory support are encountered in 20{u2013}25% of mechanically ventilated patients, with a staggering 40% of time spent in the intensive care unit being devoted to weaning. M-mode ultrasonography is now an accepted qualitative method of assessing diaphragmatic motion in normal and pathological conditions. In this study, we evaluated whether diaphragmatic excursion (DE) as measured by M-mode Sonography can be a predictor of weaning and diagnosis of VIDD. Methods: Fifty consecutive patients who required mechanical ventilation {u2265}72hrs. who fulfilled the spontaneous breath trial (SBT) criteria, at the start of a 1-hr SBT, each hemidiaphragm was evaluated M-mode Sonography with the patient in the supine position. Rapid shallow Breathing index (RSBI) was simultaneously calculated at the bedside. Ultrasonographic Diaphragmatic Dysfunction (DD) was diagnosed if an Diaphragmatic Excursion (DE) was <10 mm or negative, the latter indicating paradoxical diaphragmatic movement specialized Mahmoud Ahmed Hassan Khalil ; Supervised Yasser Sadek Nassar , Ashraf Hussein Abdelmohsen , Moamen Yahiya Mohamed Thesis (M.Sc.) - Cairo University - Faculty of Medicine - Department of Critical Care Medicine Issued also as CD Diaphragm Ultrasonography Weaning http://172.23.153.220/th.pdf http://172.23.153.220/th.pdf EG-GiCUC 160320 20250223031444.0 eng
