目的：寻求小儿经皮颈内静脉穿刺置管的捷径。方法：选１０岁以下患儿１００例，平均年龄（６．２±２．１）岁，随机分为两组（ｎ＝５０），Ⅰ组（实验组）用１８号短套针直接低位右颈内静脉穿刺置管，Ⅱ组（对照组）用传统高位穿插导引置管。结果：首次穿刺置管成功Ⅰ组４９例（占９８％）、Ⅱ组４０例（占８０％），两组比较有极显著性差异（Ｐ＜０．０１）；误穿动脉Ⅰ组１例（占２％），Ⅱ组６例（占１２％），两组比较也有显著性差异（Ｐ＜０．０５）；Ⅱ组４例首次穿刺未见回血。结论：低位右颈内静脉直接套针穿刺成功率高于传统的高位穿刺导引置管法，且并发症少，更适用于１０岁以下小儿经皮静脉穿刺中心静脉置管
Objective: To seek pediatric percutaneous jugular vein catheterization shortcut. Methods: A total of 100 children aged less than 10 years (mean age, 6.2 ± 2.1 years) were randomly divided into two groups (n = 50). Group Ⅰ (experimental group) The internal jugular vein catheterization, Ⅱ group (control group) with traditional high insertion catheter. Results: The first successful puncture catheterization group Ⅰ 49 cases (98%), Ⅱ group 40 cases (80%), the two groups were significantly different (P <0.01); (2%), and group Ⅱ (6%) (12%). There was also a significant difference between the two groups (P <0.05). Conclusion: The success rate of direct trocar penetration in the lower right internal jugular vein is higher than that of the traditional high-level puncture guided catheterization method with less complications and is more suitable for the central venous catheterization in children under 10 years old
