据多篇文献报导,避免局部组织缺氧可降低腹腔内粘连的发生率。前此,作者等曾通过实验证实,粘连形成的过程中,腹腔内氧张力有所降低,而二氧化碳张力及氧消耗率却见增高。本文进一步研究大鼠在正常情况下及造成腹腔粘连后腹内氧利用和转送的动态变化。方法:大鼠54,只用0.5％胶状二氧化硅1ml/40gm体重作腹腔内注射以造成肠粘连。1天、1周及3周后分别经可透气的
It has been reported in many articles that avoiding local tissue hypoxia reduces the incidence of intra-abdominal adhesions. Before this, the author has confirmed through experiments that in the process of adhesion formation, the intra-abdominal oxygen tension is reduced, while the carbon dioxide tension and oxygen consumption rate is increased. This article further studies the dynamic changes of intra-abdominal oxygen utilization and delivery in rats under normal conditions and after intraperitoneal adhesions. METHODS: Rats 54 were injected intraperitoneally with 0.5% colloidal silica 1 ml / 40 gm body weight to cause intestinal adhesion. 1 day, 1 week and 3 weeks after were breathable
