摘要
负压吸引吸痰法是一项侵入性操作,为了减少其对气管粘膜的损伤,探索适宜的负压值,我们对不同负压值吸痰所致气管粘膜损伤的程度,进行了动物实验。作者将实验组36只犬随机分为1～6组,吸痰负压值分别定于5、10、15、20、25、30Kpa,按常规吸痰法吸痰10次后分别处死。切取损伤的全层气管组织两块,做普通光学及电子显微镜检查。结果表明:负压吸引吸痰的负压值与气管粘膜损伤程度成正比,其负压值应控制在5～20Kpa之间,吸痰器计量表应采用低负压Kpa负压表。以便于控制、调节负压值,减少由于吸痰所致气管粘膜损伤。
Objective: To explore optimal negative pressure of the aspiratory sputum. Methods: We have done animal experiments with 36 dogs divided into 6 groups 10 times aspirating sputum by Ⅰ(5), Ⅱ(10), Ⅲ(15), Ⅳ(20), Ⅴ(25), Ⅵ (30 )Kpa respectively. Then we have taken full-thickness bronchial tissue for examination by light microscope and electronic microscope. Conclution: Negative pressure of aspiratory sputum was in proportion to injury. 10 -20Kpa negative pressure was optimal pressure.
