目的观察病毒性下呼吸道感染患儿血小板的变化。方法回顾性研究2005年6月至2007年6月温州医学院育英儿童医院收治的420例下呼吸道合胞病毒(RSV)、流感病毒、副流感病毒及腺病毒感染患儿的血小板变化。血小板增多以>400×109/L为标准。结果RSV感染患儿血小板计数明显高于其他病毒感染,在91例血小板增多患儿中,RSV感染占67例(73.6%),227例RSV感染患儿血小板增多发生率为29.5%(67/227)。与其他病毒感染比较,RSV下呼吸道感染患儿的年龄小、血红蛋白低及呼吸窘迫发生率高。结论下呼吸道病毒感染时,血小板增多易发生于RSV感染者,血小板增多可作为下呼吸道RSV感染早期实验室指标。
Objective To observe the changes of platelet in children with viral lower respiratory tract infection. Methods A retrospective study of 420 children with lower respiratory syncytial virus (RSV), influenza, parainfluenza virus and adenovirus infection in Wenzhou Children’s Hospital of Medicine from June 2005 to June 2007 was performed. Thrombocytopenia> 400 × 109 / L as the standard. Results The platelet count of children with RSV infection was significantly higher than that of other virus infection. Among the 91 cases of thrombocytosis, RSV infection accounted for 67 cases (73.6%). The incidence of thrombocytopenia in 227 children with RSV infection was 29.5% (67/227 ). Compared with other virus infections, children with RSV lower respiratory tract infection have younger age, lower hemoglobin and higher respiratory distress rates. Conclusions In the case of lower respiratory tract virus infection, thrombocytosis easily occurs in RSV infected patients. Thrombocytosis may be used as an early laboratory index of RSV infection in lower respiratory tract.
