Abstract
This research included 178 patients, 92 of whom were weaned off NIV, 56 of whom were weaned from IMV, and 30 of whom (control group) received standard oxygen treatment through nasal cannula, simple, or Venturi mask.
The research was conducted in the Respiratory Intensive Care Unit (RICU), Cardiothoracic Minya University Hospital, from November 2021 to November 2022.
The following procedures were performed on all patients:
Full medical history (age, gender, smoking status, other particular habits, and chest signs).
The General Exam.
Local Chest Examine.
Routine laboratory investigations (CBC, RFTs, s-electrolytes) are examples of studies.
Radiological examinations include a simple chest x-ray and a high-resolution computed Tomography (HRCT) of the chest.
Diaphragmatic function, excursion, and thickness are all assessed using bedside chest ultrasonography.
Once the patient met the requirements for weaning from IMV or NIV, we performed bedside chest ultrasonography.
Our findings show that diaphragmatic thickness and diaphragmatic thickening fraction are strong predictors of weaning outcome, along with the standard markers of weaning from mechanical breathing.
We advocate equipping hospitals with ultrasound equipment and training doctors on how to utilize them so that they may give better treatment to their patients.
In addition, in intensive care units, we advocate giving printed copies of weaning from mechanical ventilation.
