Utility of Lung Ultrasonography As a Predictor of Fast Track Extubation

background: Fast-tracking in cardiac surgery refers to early extubation to reduce costs and perioperative morbidity. The use of lung ultrasound is recently accepted as a tool in the assessment of several lung conditions. The aim of this study was to assess the use of lung ultrasound score as a quantitative method to assist in the decision of early extubation.

Methedology: in this prospective, observational study, 45 pediatric patients who will go elective repair of congenital acyanotic heart diseases were included and were examined with Lung ultrasound together with arterial blood gases preoperative and postoperative and given a score range from 0-3 according to number of B lines in each region and sensitivity of post-operative lung ultrasound score to extubation within 6 hours was examined Demographic data: Patients' name, age, sex, diagnosis, relevant medical and surgical history. And Assessment data: Baseline arterial blood gases and lung ultrasound score assessment after induction of anesthesia and at the end of surgery.

Primary outcome will be the sensitivity of lung ultrasound scores immediately at the end of pediatric cardiac operation in prediction of extubation. and Secondary outcome will be correlation between lung ultrasound score and Po2/Fio2 ratio at the end of operation
