Abstract: Objective  To explore the clinical characteristics and prognostic factors of extrapulmonary complications in children with mycoplasma pneumonia (MPP). Methods  The clinical data of 276 cases of MPP complicated with extrapulmonary complications were retrospectively analyzed. The patients were divided into good prognosis group (169 cases) and poor prognosis group (107 cases). The clinical manifestations of extrapulmonary complications were recorded to  analyze different system damage. The singlefactor and multiplefactor analysis were conducted to analyze the risk factors that may affect the prognosis of MPP children with extrapulmonary complications. Results  Extrapulmonary complications in children occurred in digestive system and other systems,  and digestive complications accounted for the highest proportion. The singlefactor and multiplefactor analysis showed that the independent risk factors which affected the prognosis of children with MPP complicated with extrapulmonary complications were the course before admission,  CRP,  ESR,  anemia,  albumin <30 g/L,  initial usage time of azithromycin,  pulmonary consolidation,  complications involving multiple systems. Conclusion  MPP may cause multiple system complications,  and digestive system complications were the most common. The independent risk factors that affected the prognosis of MPP children with extrapulmonary complications included preadmission course,  CRP,  ESR,  anemia,  albumin < 30 g/L,  initial usage time of azithromycin,   pulmonary consolidation and complications involving multiple systems.
