针道粘堵技术预防 TNAB 后气胸的动物实验研究

EXPERIMENTAL STUDY ON THE EFFECT OF SEALING-NEEDLE-TRACK IN PREVENTING PNEUMOTHORAX AFTER TNAB

将家兔分为实验Ａ组（２１只）、Ｂ组（２０只）、Ｃ组（１８只），对照Ｄ组（２４只），进行经胸针吸活检（ＴＮＡＢ）后实验组分别以ＺＴ胶、显影ＺＴ胶、自体血凝块粘堵针道，于不同时间记录气胸出现时间、出现率及严重程度。１６５次穿刺中，出现气胸２６例，多在１小时后出现（９６．１５％）；实验组气胸率（７．６２％）及严重程度（１．６９％），低于对照组（３６．１７％，８．５１％）（Ｐ＜０．０１）。ＺＴ胶类组又低于自体血凝块组；９６．１５％的气胸出现于术后１小时内。结果表明，针道粘堵技术能有效预防ＴＮＡＢ后气胸地发生，ＺＴ胶类效果优于自体血凝块；术后１小时内透视／摄片能检测到绝大多数活检后气胸。

Eighty three rabbits were randomly divided into control group (n=24)and treated groups(n=59,groups A,B,C).After the TMAB was performed,“ZT glue”,“Developing ZT glue”and “autogenous blood clot”were used to seal needle track in group A,B and C,respectively.The pneumothorax rate was 36.17% in control group and 7.62% in treated group(group A was 4.76%,B 2.5%,C 16.17%)。The 96.15% of pneumothorax appeared during the lst hour after TNAB.
