摘要
为进一步了解静脉输液进针长度对血管壁的影响,我们对8只家兔和62例住院病人再次进行自身血管损伤程度的对照观察,进针长度分别为0.6cm和1.2cm。结果显示,进针1.2cm组,无论是动物还是病人,其疼痛反应、血管壁损伤、管周组织瘀血、血管阻塞程度等均明显大于进针0.6cm组(P〈0.01)。且进针1.2cm组每条静脉平均使用寿命也明显短于进针0.6cm组。提示临床护理人员行静脉输液时,在确保针头进入血管、达到牢固固定的前提下,应尽量减少针头进入血管的长度。
To know the affect on vascular wall of different intravenous infusion needling length, of 8 rabbits and 62 inpatients were comparatively observed. The lengths of needling were 0. 6 em and 1.2 em respectively. And the degree of vascular injury was the main observation index. Results showed that in either rabbits or patients, their vascular injury degree was more severe in needling length of 1.2 em group than that in needling length of 0. 6 em group ( P 〈 0. 01 ). Vascular injury included pain reaction to the infusion, vascular wall injury, circumvaseular tissue with stasis of blood, and vascular occlusion. And results also showed that of 1.2 em length needling group, the mean service life of each vein was significantly shorter than that of 0. 6 em needling length group. Suggested that when nurses give venous transfusion to patient, one should reduce the length of needling within the vascular.
