Background: Diaphragm dysfunction (DD) is frequently seen in
critically ill patients, and ultrasound could be a useful tool to detect it
and to predict extubation success or failure in mechanically ventilated
patients. Besides, it would also be useful in differential diagnosis of
dyspnea and respiratory failure. Aim of work :The aim of work is to
evaluate usefulness and accuracy of ultrasound in assessment of DD
in intensive care unit (ICU) patients in comparison with clinical
outcome of patients.. In this prospective study, we compared the
performance of ultrasound in visualization of diaphragm, detection of
paradoxical movement, measurement of tidal and maximal thickness,
and excursion, and calculation of thickening fraction (TF) of the
diaphragm in quiet breathing. Patients and Method: The present
study was performed on50 patients (26 males and 24 females)
admitted in RICU in Benha university hospital The field study was
conducted from March 2019 to September 2019. Ultrasound of the
Rt, hemidiaphragm was done on the day of admission or soon after
admission (1-2) days. Results: there was no statistical significant
difference between the studied groups regarding ultrasound
measurement (DTF, DE and DT) and patient outcome with p value
(0.273,0.245 and 0.497)respectively .Conclusion: ultrasound of
diaphragm in ICU patients may be a reliable, noninvasive and
convenient way to assess the DD in ICU patients to predict their
outcome.
