长时间血液透析的益处课件

1、长时间血液透析的益处卢方平2009-4-30长时间血液透析的益处卢方平病例报告姓名 庞洁 性别 女 年龄25岁 民族 汉族因维持性血液透析5年半，大量腹水1年3个月于2008年9月转入我院继续治疗。病例报告姓名 庞洁 性别 女 年龄25岁 患者于2002年底因“肺结核”在外地抗结核治疗（免费药）中出现肾损害，肾功能减退，伴肾性贫血与高血压，用中药治疗无效后于2003年4月在北京某医院接受血液透析治疗（5次/2周3次/周，每次4小时）。血管通路为中心静脉半永久导管。透析半年后残余肾功能丧失（尿量为）2007年6月发现腹水。2007年8月中心静脉半永久导管感染，而后改为左前臂动静脉内瘘。虽经抗感染

2、治疗与多次放腹水（最多放4000ml），此后腹水进行性加重，于2008年9月转入我院。 患者于2002年底因“肺结核”在外地抗结核治疗（免费药）中出既往史：9岁时曾患甲亢，已治愈。年前患乙型肝炎。对他巴唑过敏。无食物过敏史。有输血史。既往史：9岁时曾患甲亢，已治愈。年前患乙型肝炎。对他巴唑过体 格 检 查：慢性病容，贫血貌。营养状态差。未见肝掌、蜘蛛痣。全身浅表淋巴结未及。睑结膜苍白，巩膜无黄染。无颈静脉怒张。胸廓未见异常，双侧呼吸运动对称，语颤双侧对称，双肺呼吸音粗，未闻及干湿罗音。心前区无隆起，心尖搏动位于第五肋间左侧锁骨中线外侧0.5cm处,搏动范围无弥散, 心率108次/分，律齐，未闻

3、及病理性杂音。腹部平坦腹膨隆,无压痛，肝脾触诊不满意，全腹叩诊呈浊音，移动性浊音（+），腹水征（+），肠鸣音听诊不理想。双下肢水肿（-）。体 格 检 查：慢性病容，贫血貌。营养状态差。未见肝掌腹部B超：双肾萎缩，双肾弥漫性病变，腹盆腔多量积液。盆腔深20cm。腹部CT：肝脏外形规整，各叶比例正常范围内，肝实质内未见异常密度。肝内外胆管未见扩张及结石。腹部B超：双肾萎缩，双肾弥漫性病变，腹盆腔多量积液。盆腔深22008-4-7北京xx医院1.肝大:剑下5.4cm,肋下1.0cm,右肝斜径16.7cm2.肝静脉增宽:左1.6cm,中1.2cm,右1.6cm3.脾大:厚4.7cm,长14.2cm,肋
