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.
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.
