肺铸型标本对于理解肺内管道系统的解剖、指导纤大镜检查以及制定手术计划具有重要参考价值,文献对其制作方法均有介绍,其中以新鲜离体肺铸型较易成功.然肺离体后失去了胸腔负压和滑液的吸附、易致肺萎陷和位置变动.铸型行失正确与美观,迄今尚未有行之有效的解决办法.作者探讨在体肺经外周插管铸型.取得较满意效果,总结于下.1 材料和方法11 取材 新鲜尸体分别于环状软骨和脐平面离断颈、腰部;自肩关节处去掉上肢,经气管和颈部血管断端插管稍加冲洗.如果死亡时间较长(超过24小时),则须于温生理盐水内加适量枸橼酸钠、重铬酸钾和醋酸,反复灌洗血管.然后经气管插管灌注膨胀固定液,其成分为聚乙二醇400、95%乙醇、40%甲醛和常水,比例为3:2:5:10,灌注量视胸壁隆起约
Pulmonary cast specimens for the understanding of the lungs of the anatomy of the duct system, guiding the detection of fibrillation and the preparation of surgical planning has important reference value, the literature on its production methods are introduced, of which the new isolated lung model easier to succeed. Lost in vitro after the suction and the suction of the thoracic cavity, easy to cause lung collapse and location changes. Casting line is correct and beautiful, so far there is no effective solution. The authors explore in the lung by peripheral intubation Mold. To obtain more satisfactory results, summarized in the next .1 Materials and methods 11 fresh corpses were taken from the annular cartilage and umbilical plane off the neck, waist; remove the upper extremities from the shoulder joints, tracheal and neck vascular end cannulation slightly Plus flushing.If the death for a long time (more than 24 hours), you should be in warm saline, add appropriate amount of sodium citrate, potassium dichromate and acetic acid, repeatedly lavage blood vessels and intubation intubation expansion fluid, Its composition is polyethylene glycol 400, 95% ethanol, 40% formaldehyde and normal water, the ratio is 3: 2: 5: 10,
