Overview of Lung Ultrasound in Pediatric Cardiology

Area of Science:

• Pediatric Cardiology
• Critical Care Medicine
• Diagnostic Imaging

Background:

• Lung ultrasound (LUS) is gaining traction for diagnosing pulmonary complications in acute pediatric care.
• Its application in pediatric cardiovascular and congenital heart disease patients, especially post-cardiac surgery, remains limited.
• Pulmonary complications are common in these vulnerable children.

Purpose of the Study:

• To provide a comprehensive review of current and potential LUS applications in children with congenital heart disease post-surgery.
• To outline LUS protocols, diagnostic criteria, and methods for common pulmonary diseases.
• To explore LUS utility in evaluating the retrosternal area and guiding interventional procedures.

Main Methods:

• Review of existing literature and established protocols for LUS in pediatric cardiac surgery patients.
• Description of diagnostic criteria for pleural effusion, atelectasis, interstitial edema, pneumothorax, and pneumonia.
• Illustration of techniques for retrosternal area evaluation and interventional guidance.

Main Results:

• LUS protocols and diagnostic criteria for common pulmonary conditions are detailed.
• Applications for evaluating retrosternal clots and guiding procedures like lung recruitment and drainage insertion are presented.
• Current knowledge gaps, such as quantifying pleural effusion/atelectasis and differentiating B-line etiologies, are identified.

Conclusions:

• Lung ultrasound is an accessible, accurate, rapid, cost-effective, and radiation-free tool for diagnosing and managing pulmonary complications in pediatric cardiac surgery.
• Routine adoption of LUS in pediatric cardiac surgery care is strongly recommended.
• Future research directions include advanced LUS techniques like strain analysis and diaphragmatic mechanics.
