ROLE OF LUNG ULTRASOUND IN DETECTION OF RESPIRATORY DISEASES IN PAEDIATRIC INTENSIVE CARE UNIT OF A TERTIARY CARE HOSPITAL OF SINDH, PAKISTAN
Abstract
Objectives
To determine the diagnostic accuracy of lung ultrasonography in detection of respiratory diseases in PICU keeping Chest X ray as gold standard.
Study design
Descriptive cross-sectional study.
Place & duration of study
Study was conducted in the Department of Paediatric Intensive care unit, The Indus Hospital, Karachi from 1st June 2022 to 31th December 2022.
Material and Methods
160 children of either gender between the ages from 1 month to 12 years, fulfilling the inclusion and exclusion criteria, were included in the study after seeking written informed consent. Detailed history and physical examination were carried out that was followed by point-of-care (POC) lung ultrasound (LUS) for the presence or absence of sonographic findings related to different lung diseases. Chest X ray using mobile radiography system in PICU was subsequently done of all the patients. Tabulated data collection form was designed and kept in the PICU and all relevant data was recorded. SPSS version 23 was used for data analysis. Frequency and percentages were calculated for all the categorical variables while mean and standard deviation were calculated for the quantitative variables like age. Sensitivity (ST), specificity (SP), positive predictive value (PPV) and negative predictive value ( NPV) were calculated.
Results
Lung ultrasonography showed a diagnostic accuracy of 93.51% for pneumonia, 63.63 % for pneumothorax, 91.93% for pleural effusions and 80% for interstitial lung diseases.
Conclusion
Our results indicated that POC LUS is an extremely useful radiation-free imaging modality in detection of common respiratory diseases in a PICU setting that is reliable, safe and cost effective in management of critically ill pediatric patients.
