摘　　要：目的研究静脉留置针在不同留置时间与静脉血管的炎症反应相关性。方法将种系相同，体重相近的大耳新西兰健康白兔随机分成两组。取其双耳内外倜的耳缘静脉作为实验血管，进行静脉留置针输液，以相同的速度分别输入等量的0．9％氯化钠注射液，每日1次。输毕后用肝素盐水封管，分别保留至72—96h和120-168h后，以一穿刺点为中心取长2cm，宽1cm的活体标本做病理南片，观察静脉血管的病理变化。结果血管周围组织大部均有不同程度的炎症反应。静脉留置针保留72—96h后，血管内中重度炎症发生率24％；静脉留置针保留120-168h后，血管内中重度炎症发生率60％，明显高于保留72—96h的血管。结论建议静脉留置针保留时间应在96h以内。Objective To study the relationship between the retaining time of I.V. catheter system and inflammation of vein. Methods Healthy New zealand rabbits with the same breed an weight were divided into two groups. The veins at the outside and inside edges of the two ears were taken as tested blood tubes for the infusion with I.V. catheter system. The same amount of 0.9% sodium chloride injection solution was infused daily once at the same speed, blocked with heparin salt water after the infusion and retained for 72-96 hours an 120-168 hours respectively. 2cm-long and 1cm-wide llve sample from the puncture piont was taken to make pathological section and the pathological change of vein was observed. Results There was inflammation in most part around vein. When I.V. catheter system was retained for 72-96 hours, the rate of heavy inflammation was 24%, when retained for 120-168 hours, the rate of heavy inflammation was 60%, obviously higher than the former. Conclution It is suggested .that the retaining time of I.V.catheter system be within 96 hours.
