Brief summary: Pulmonary complications are frequent in cardiac surgery, representing an important cause of morbidity, prolongation of hospital stay and need for repeated examinations.Chest X-rays are done routinely and even multiple times to detect such complications.Lung ultrasonography is an alternative test to detect pulmonary complications that can be done easily on bedside. Regularly done Chest X-ray exposes patient to ionizing radiation which can be reduced with ultrasonography. Lung ultrasound is gaining popularity in recent years as a non-invasive,radiation-free tool for the diagnosis of various acute and chronic pulmonary diseases due to its bedside convenience, accuracy, and free of radiation.There is increasing evidence to support the use of Lung ultrasound in acute care setting and post-cardiac surgical patients are also considered critically ill. The purpose of this study is to compare diagnostic performance of lung ultrasound in comparison to chest X-ray to detect pulmonary complication after cardiac surgery in children.

Detailed description: Study type: Comparative Study design: Non-randomized,all patients will undergo both ultrasound and chest Xray.

Model:cohort time perspective: prospective Sampling method: non-probability sample Study population: Children less than 14 years Sample size: 54 Place of Study-Shahid Gangalal national Heart Center, Surgical intensive care unit Duration of study: six months Hypothesis: Chest X-ray and Lung ultrasound are equally effective in detecting postoperative pulmonary complications

Inclusion criteria:

Patients after undergoing cardiac surgery who are age below 14 years on post-operative Day 1.

Exclusion criteria Patient's /Guardians' refusal IMAGING PROTOCOL AND TECHNIQUE Following institutional review board approval, a written informed consent will be obtained from all the patients meeting the inclusion criteria before undergoing surgery on pre-operative visit before enrollment in the study.

Lung Ultrasound will be done on the first post-operative day of cardiac surgery and will be compared to Chest X-ray done on the same day for any pulmonary complications . Lung ultrasound examination will be performed by radiologist to detect pleural effusion, consolidation, pulmonary atelectasis, pneumothorax and pulmonary congestion, using Siemens AUCUSON Freestyle Diagnostic Ultrasound System L13-5 linear probe. The transthoracic Lung ultrasound approach will be done in supine and both lateral decubitus positions of the anterior lung area (between the sternum and the anterior axillary line), lateral lung area (between the anterior and posterior axillary lines), and posterior lung area (between the posterior axillary line and the spine) in caudo-cranial direction. Longitudinal, transverse and oblique scans will be included. A routine plain chest radiograph will be obtained in each patient on the same day before performing ultrasound which will be evaluated by an intensivist to detect pleural effusion, consolidation, pulmonary atelectasis, pneumothorax. Both the radiologist and intensivist will be blinded to each other's findings. Comparison of the findings will be done at the end of study.
