It is a prospective double blind study done on total 200 patients. Who were weaned from ventilator after being ventilated for > one week due to respiratory failure. This respiratory failure was selected in our study to be from severe lung contusion and post-traumatic acute respiratory distress syndrome. Patients were randomly allocated in one of two groups each group contain 100 patients. Group A considered control group. Those patients weaned from the ventilator by the conventional criteria of weaning. While group B weaned from the ventilator by the ultrasound criteria of weaning. All patients weaned from both groups followed for six days for signs of failure of weaning ,signs of post-extubation respiratory failure. And number of patients who were re-ventilated and who discharged from ICU in both groups recorded and compared.
compare and evaluate the effect of use of ultrasonic criteria of weaning versus the conventional ways of weaning in post-traumatic acute respiratory distress syndrome (ARDS) patients who were ventilated for a long time. And compare their effect on the duration of ICU stay.
