摘要
目的探讨唾液吸入显像对儿童肺吸入的诊断价值。方法回顾性分析2006年1月至2011年12月间于北京友谊医院行99Tc^m-硫胶体唾液吸人显像的469例患儿[年龄6周-16岁，平均年龄（4．5±3．1）岁；男229例，女240例1资料。患儿家属均签署知情同意书。将含有11．1MBq的1滴（100μL）99Tc^m-硫胶体滴于患儿舌根部，即刻行后位动态采集，共60min，结束后采集前位和后位2张胸部静态图像5min。若主支气管或双肺野显影或出现放射性，则诊断为肺吸入。所有患儿检查结束后随访3～6个月，随访比较唾液吸入显像的诊断结果。结果唾液吸入显像示20．7％（97／469）的患儿肺吸入唾液。假阴性3例，无假阳性发生。结论唾液吸入显像诊断儿童肺吸入的价值较大。
Objective To investigate the value of salivagram in the diagnosis of pediatric pulmona- ry aspiration. Methods A total of 469 pediatric patients （age： 6 weeks-16 years, average age （4.5_＋3.1） years; 229 males, 240 females） underwent salivagram. Signed informed consents were obtained. 99Tcm-SC （ 11.1 MBq, 100 ~1） was dropped into the root of tongue. After the dropping, the posterior dynamic acquisi- tion was started for 60 min, and then the anterior and posterior static images were acquired for 5 min. All patients were followed up for 3-6 months after the salivagram, and the salivagram results were analyzed. If radioactivity was shown in the main bronchus or bilateral lung fields, the pulmonary aspiration was diag- nosed. Results Salivagram demonstrated positive results in 20.7% （97/469） of the patients. However, 3 patients with pulmonary aspiration showed negative results. There was no false positive result on salivagram. Conclusion Salivagram shows good results in the diagnosis of pediatric pulmonary aspiration.
