Abstract
Diaphragmatic dysfunction has become a subject of major
concern in critical ill patients, because it is associated with a higher rate
of weaning failure, increased duration of mechanical ventilation and
consequently increased the length of stay in ICU (Kim WY et al, 2011).
Ultrasound evaluation of the diaphragm is simple, non-invasive,
and readily available at the bedside and increasingly used both in the
clinical and research settings (Zambon M et al., 2017). It can assess the
diaphragm dysfunction and its influence on weaning outcome in
mechanically ventilated patients (Ali ER and Mohamed AM et al,
2016).
Aim of the Work:
Sonographic assessment of diaphragmatic function as a predictor
for weaning from mechanical ventilation.
Patients and methods:
This study included 30 patients admitted in ICU units of Fayoum
university hospital who are invasively mechanically ventilated during
the period from July 2018 to July 2019. All patients were subjected to
full medical history taking, detailed general and local clinical
examination ,chest X ray, laboratory assessment, using ultrasound
machine to measure diaphragmatic excursion (DE), diaphragmatic
thickening fraction (DTF), contraction velocity, and relaxation rate
during first 24 hours of intubation, first 24 hours of weaning process
and among successful weaning group the same measures are assessed
after extubation (within first 48h) and before discharge or referral to
ward.
