Lung Ultrasound Score and Weaning Outcome

Lung Ultrasound Score for Prediction of Weaning Outcome

Objectives: Failure of extubation of patients on mechanical ventilation is one of the common problems in the ICU.

Aim of work: To evaluate the validity of lung ultrasound score in prediction of weaning outcomes and post-extubation distress.

Methods: A prospective observational study of 50 patients planned for extubation who passed a spontaneous breathing trial, lung ultrasound score and serum level of NT-PRO BNP were done to all patients at end of spontaneous breathing trial, and all patients were followed after extubation and monitored for oxygenation, re-intubation rate, ICU stay, and ICU mortality.

Inclusion Criteria:

- 1. Patients age > 18 years

2. Patients intubated and mechanically ventilated for more than 48 hours in the intensive care unit and planned for extubation.

Exclusion Criteria:

• 1. Patients < or =18 years 2. Patients with left ventricular failure

  3. Right ventricular failure

  4. Pulmonary hypertension

  5. Aortic valve disease

  6. Hyperthyroidism

  7. Tracheostomy
