利用绵羊(或山羊)慢性肺淋巴瘘模型,可较为客观地研究肺微血管内外液体及蛋白质交换规律。但目前国外采用的Staub、Winn和Stothert等人的方法,制作一只模型须经2～3次开胸手术(包括肺淋巴造瘘和左心房插管),历时2～3周。手术创伤大,而且耗时、耗力、耗资。减少手术次数,缩短模型制作所需时间是有待解决的问题。 The use of sheep (or goat) chronic lung lymphatic fistula model can be more objective study of pulmonary microvascular intravascular and protein exchange rules. However, currently abroad, Staub, Winn and Stothert et al.’s method of making a model required 2 to 3 thoracotomy (including pulmonary lymphangostomy and left atrial cannulation) lasted 2 to 3 weeks. Surgical trauma, but also time-consuming, labor-intensive, costly. Reduce the number of operations, shorten the time required for model making is a problem to be solved.
