The Importance of Dynamic Monitoring of Cardiopulmonary Ultrasound in Evaluating Severe Pneumonia in Pediatric Patients

Severe pneumonia poses a significant health threat to children, contributing to high morbidity rates and substantial economic burden.This study investigates the clinical value of combined cardiac and pulmonary ultrasound in assessing cardiopulmonary function in children with severe pneumonia at different treatment stages. Severe pneumonia remains a critical health issue among young children, with timely and accurate assessment of cardiopulmonary function being essential for effective management.A prospective observational design was employed, involving 60 children aged 3 to 5 years diagnosed with severe pneumonia, who underwent both combined cardiac and pulmonary ultrasound and conventional chest X-ray examinations. The results demonstrated significant dynamic changes in cardiopulmonary function throughout the treatment phases, with key indicators such as left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), and tricuspid annular plane systolic excursion (TAPSE) showing marked improvement post-treatment (P<0.05), while the E/e′ ratio significantly decreased. Additionally, a negative correlation was found between lung ultrasound scores and chest X-ray grading (r=-0.736; r=-0.573; r=-0.609, P<0.001), highlighting the potential of ultrasound in prognostic evaluation. The study underscores the advantages of using combined cardiac and pulmonary ultrasound for dynamic monitoring of cardiopulmonary function in severe pneumonia cases. However, limitations such as a small sample size and absence of long-term follow-up warrant consideration. In conclusion, this research supports the incorporation of combined ultrasound techniques in clinical practice for better assessment and management of severe pneumonia in pediatric patients, suggesting further exploration of its applicability in other respiratory diseases.
