Diagnosis of pneumonia in paediatric age group by comparing two modalities chest x-ray versus ultrasonography at tertiary care hospital

: Up to 20 million cases of pneumonia in children ages 0 to 5 years require hospitalization each year, from total 150 million cases of pneumonia. The most common cause of death in children worldwide is pneumonia. Due to the general non-specificity of the signs and symptoms, clinical history and physical examination cannot reliably distinguish between the causes of respiratory cases. As a result, accurate diagnosis frequently requires medical imaging, but two-thirds of the world's population lack access to diagnostic imaging, which lead to increasing the consequences of respiratory illnesses. : To know the characteristic of pneumonia in x-ray and ultrasonography. To compare X-ray chest and USG for early diagnosis. : A Prospective observational study was conducted among 100 paediatric patients diagnosed with pneumonia and admitted in paediatric ward, at New Civil Hospital, Surat. : Out of total, 52.7% and 47.3% patients were Males and Females, respectively. 87.2% cases were fully immunized, while remaining were partially immunized. Sensitivity and specificity of chest X-ray is 83.4 % and 86.8 % respectively. Sensitivity and specificity of USG thorax is 96.8 % and 90.5 % respectively. Young children are at least four times more susceptible to radiation damage than adults.: In comparison to chest radiography, lung ultrasound has the potential advantages of being more sensitive and specific, radiation-free, subject to less regulatory constraints, relatively less expensive so it can be used in diagnosis in patients with pneumonia.
