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 Issued also as CD Diaphragm Ultrasonography Weaning Ashraf Hussein Abdelmohsen , Supervisor Moamen Yahiya Mohamed , Supervisor Yasser Sadek Nassar , Supervisor http://172.23.153.220/th.pdf Aml Cataloger Nazla Revisor ddc TH 55652 55652 ddc 0 CUCL cl210 2024-02-11 Cai01.11.09.M.Sc.2015.Ma.V 01010110068143000 2023-09-22 00:00:00 TH ddc 0 CUCL cl2u8 2024-02-11 Cai01.11.09.M.Sc.2015.Ma.V 01020110068143000 2023-09-22 00:00:00 68143.CD CD
