医学动画文字记录:医生可能会对你进行经胸穿刺活检(TNB),以诊断肺部或肺部附近的疾病。肺位于胸腔。在肺表面和胸壁之间有两层叫做胸膜的组织。一层是脏层胸膜,与肺本身相连,而另一层是壁层胸膜,与胸壁相连。胸腔是两层胸膜之间的空隙,胸腔里有少量液体,可以让肺部在每次呼吸时顺畅地扩张和收缩。经胸穿刺活检可用于诊断哮喘、肺癌、肺炎和胸部损伤等疾病。在检查之前,你可能会被给予抑制咳嗽的药物。医生可能会使用各种成像技术,如CT扫描或超声波,以帮助精确定位活检的部位,并指导入针。要清洁肋骨上方的皮肤。为了帮助你放松,会使用温和的镇静剂,并使用局部麻醉来麻痹该部位。一个典型的操作需要不到30分钟。首先,医生会在皮肤上做一个小切口,将针插入。然后,你需要屏住呼吸,尽可能保持不动,医生会把针穿过你的皮肤和胸壁。你可能会感到压力,然后当针头到达肺表面时,还会感到迅速而尖锐的疼痛。医生会迅速获取液体或组织样本,然后取出针头。通过胸部x线或其他成像技术的检查来确保肺没有萎陷。恢复时间通常很短。如果没有并发症,你可以在手术当天回家。
