Abstract: There have been great progress in the diagnosis，treatment and management of patients with primary immune thrombocytopenia（ITP） in the recent 10 years. Based on the new data，the new ITP International Working Group had updated the old International Consensus Report（ICR，Version 2010） in 2019. The 2019 consensus provides recommendations on the diagnosis and differential diagnosis，first-line treatment，emergency treatment for critically ill patients and second-line treatment for ITP in adults，during pregnancy，and in children，as well as life quality management and sporting activities. The article will focus on interpretation of recommendations on ITP for children in the consensus，in order to provide useful information for standardized clinical diagnosis and treatment.
