Abstract
BACKGROUND: To evaluate the diagnostic value of pulmonary ultrasound combined with plasma procalcitonin (PCT) and serum amyloid A protein (SAA) in children with Mycoplasma pneumoniae pneumonia (MPP). METHODS: Clinical data of 80 children with community-acquired pneumonia who underwent lung ultrasound examinations and were admitted to our hospital from January 2023 to December 2023 were collected. Children with MPP were divided into an MPP group and a non-MPP group on the grounds of whether they were MPP patients. Meanwhile, PCT and SAA levels were checked, and lung ultrasound and PCT and SAA examination results were collected and compared. The ROC curve was used to evaluate the value difference of the three alone and in combination in diagnosing mycoplasma pneumonia.
