大角度静脉穿刺术的临床与实验研究

目的 验证大角度静脉穿刺术的临床应用价值。方法 将大角度一胸脉穿刺术与常规静脉穿刺术各行８１５例次临床应用，观察静脉穿刺的速度与质量，以及两种静脉穿刺术对兔耳静脉穿刺后局部病理组织改变的影响。结果 临床对比应用表明，大角度静脉穿刺组回血时间缩短１．２４ｓ，一针成功率提高４．１１％，皮下瘀血率减少０．７１％，各项指标皆有显著性差异，Ｐ值均〈０．０１动物实验提示，大角度静脉穿刺组静脉管壁周围组织损伤程

The clinical and experimental research of large angle vein puncture

Objective To verify clinical application value of vein puncture by large angle.Method We performed vein puncture by large angle and normal vein puncture on 815 cases respectively and observed the speed and qualified effects of vein puncture and influence on pathological tissue changes of rabbit's vein puncture part.Result Clinical application showed that the time of backward blood in vein puncture group by large angle shorten 1.24second, the successful rate by one injection increased 4.11%, the rate of subcutaneous stasis blood reduced 0.71%. All indexes were of signicient difference ,p<0.01; Animal experiment indicated that the damage of subcutaneous tissue and blood tube wall were less in vein puncture group by large angle.Conclusion Vein puncture by large angle has many advantages. That is ,the time of backward blood is fast after puncture, the successful rate by one injection is high, the degree of damage is less and the patient's pain is slight. Therefore, It is of spreading application value.
