摘　　要：目的:研究影响脐静脉穿刺的相关因素, 如何安全、有效、简便的获取胎儿脐静脉血, 减少患病儿的出生, 提高人口素质。方法: 孕妇取仰卧位或侧卧位, 腹壁常规消毒、铺巾。用无菌穿刺探头选好穿刺的脐静脉, 并测量目标距体表的距离, 用22G穿刺针插入穿刺槽内, 快速有力一次进针达穿刺脐静脉, 抽取脐血2ml。结果: 154例中穿刺成功率95 .45%, 一次成功率82. 46%。结论: 影响穿刺成功的因素主要有孕龄、穿刺深度、胎盘位置、操作技术、一次穿刺法、耦合剂等。Objective:By exploring the influential factors related to umbilical vein puncture to safely effectively and easily obtain fetal umbilical vein blood sampling and reduce the birth of fetus with diseases and improve population quality.Methods:The pregnant women with dorsal position or lateral position were sterilized on their abdominal skin.The umbilical vein selected was punctured with sterile probe and the depth from the punctured point to abdominal surface was measured.2 ml cord blood was sampled with 22G needle quickly punctured in umbilical vein.Results:Of 154 cases of punctures,the successive rate was 95.45%,the primary successive rate was 82.46%.Conclusion:The main factors concerning success of puncture included gestational age, the depth from umbilical vein to abdominal surface, site of placenta, operative skill, and coupling agents etc.
