Additionally, in some patients, the median cephalic or basilic ein was relocated subcutaneously to increase the accessibility of eins for puncture.

另外，在一些患者中，头静脉或者贵要静脉中央部分被重新放置于皮下以提高静脉穿刺的可及性。

Action c22 "a phlebotomist performs a venipuncture with a syringe" as shown in Figure 4 can be represented with the DIPs, an agent "phlebotomist", an act "performing", an object "venipuncture", and a tool "syringe" as follows

动作c22"一个医师用一个注射器进行静脉穿刺的操作"，在图4里用DIPs描述成，一个活动者"医师"，一个活动"操作"，一个对象"静脉穿刺"，和一个工具"注射器"，如下

Objective:to reduce the suffering of patients with venous puncture.

目的：减少患者静脉穿刺的痛苦。

Objective:To provide anatomical bases for percutaneous puncture of subclavian vein for approaching the heart.

目的 ：为锁骨下静脉穿刺的心脏介入通路提供解剖学依据。

The failure to reduce or avoid the venipuncture is the key to improve the psychological quality of nursing their own, and only nurses have a very good psychological quality, in order to improve the success rate of vein puncture.

减少或避免静脉穿刺失败的关键在于提高护士自身的心理素质，只有护士具备了很好的心理素质，才能提高静脉穿刺的成功率。

To analyze the accuracy and complications of amniocentesis and cordocentesis and look for the best method that collect specimen used for prenatal diagnosis.

To systematicallyinvestigate this landmark, we conducted a study in four phases:1 Two blindfolded examiners determined the distance betweenthe tuberosity's medial border and the clavicle's lateral endin 100 dried clavicles and then 2 performed subclavian veincannulation in 20 fresh human cadavers using the tuberosityand the suprasternal notch as landmarks. 3 Three-dimensionalreconstructions of the subclavian artery and vein and surroundingstructures were derived from computed tomography datasets of10 patients. The length of the path of a virtual subclavianvein cannulation with the deltoid tuberosity landmark was measuredbilaterally. 4 In a prospective, randomized trial, subclavianvein cannulation was performed in 60 patients with a standardapproach or with the deltoid tuberosity as landmark.

为系统地研究这个解剖标志，作者将本研究分为四个阶段：1 双盲检查100个干燥的锁骨测量其三角肌粗隆内侧缘至锁骨侧面末端的距离；2 在20具新鲜的尸体上以三角肌粗隆和胸骨上切迹为标志进行锁骨下静脉穿刺；3 利用 CT 所获取的数据资料对10个病人的锁骨下动脉和静脉以及周围结构进行三维重建，测量两侧以三角肌粗隆为标志的虚拟锁骨下静脉置管路径的长度；4 选择60例病人以标准路径或三角肌粗隆为标志进行锁骨下静脉穿刺的前瞻性随机试验研究。
