Lung Function Evaluated By Structured Light Plethysmography in Children After Lung Surgery: A Preliminary Analysis.

Area of Science:

• Pediatric Surgery
• Pulmonology
• Medical Imaging

Background:

• Children undergoing lung surgery often have complex clinical histories.
• Assessing lung function in young children post-surgery presents challenges due to age and cooperation limitations.

Purpose of the Study:

• To evaluate the utility of structured light plethysmography (SLP) in assessing lung function in children after lung resection surgery.
• To compare SLP findings with spirometry in this pediatric population.

Main Methods:

• Thirty-two children who underwent lung surgery were enrolled.
• Clinical history, spirometry, and structured light plethysmography (SLP) were performed.
• SLP captured chest wall movements to evaluate tidal breathing patterns.

Main Results:

• Spirometry was normal in 9/22 patients, with 9 showing a restrictive pattern and 4 mild bronco-reactivity.
• Structured light plethysmography (SLP) identified an obstructive pattern in 10% of patients.
• SLP revealed significant differences between hemithoraxes in 29% of patients, indicating potential asymmetry.

Conclusions:

• Structured light plethysmography (SLP) shows promise as a non-collaborative, radiation-free method for evaluating lung function in children post-lung resection.
• SLP may be particularly valuable for assessing preschool-aged children who cannot perform spirometry.
