颈静脉

It＇ s best to choose basilic vein at first, especially the right side, with the puncture point going over the elbow joint; and the next best choice is the jugular external vein on the right side as well.

在非高速度滴注的情况下，尽量选用小管径的导管；对血管的选择应当首选贵要静脉，优选右侧，穿刺点最好过肘关节，其次选择颈外静脉优选右侧；选择PICC置管操作应慎重，操作之前做好详细的评估。

It is better to choose small diameter catheter as far as possible if it does not request super-speed drop. It's best to choose basilic vein at first, especially the right side, with the puncture point going over the elbow joint; and the next best choice is the jugular external vein on the right side as well. Thereby, it is better to choose cautiously the PICC tube operation and make detailed valuation before operation.

Results: There were no complications detected in external jugular vein group, but the operation failed in 5 cases.

结果：经颈外静脉组未发现并发症，但有5例导管不能插入上腔静脉。

Using internal jugular vein: injury to the carotid artery, resulting in stroke.

经颈内静脉中心静脉置管：可能会误伤颈动脉，导致脑卒中。

Objective: To explore the rescue effect of external jugular vein catheter and the subclavian vein catheterization infusion in patients with upper gastrointestinal bleeding,and to provide a theoretical basis for clinical care.

目的：探讨颈外静脉留置针置管和锁骨下静脉穿刺置管输液在上消化道大出血患者抢救中的应用效果，为临床护理工作提供理论依据。

It is interesting that cervical root avulsion is a relatively frequent cause of superficial siderosis of the CNS. It is possible that trauma to the nerve root damages the fine venous plexus within the root, or the medullary and radicular veins that run along the nerve root, resulting in a fragile vascular scar.

很有意思的是颈神经根撕脱也是相对比较常见的病因之一，可能因为神经根的创伤可损伤神经根处的静脉丛及沿着神经根走行的根静脉，导致脆性血管损伤形成疤痕，当屈伸颈部时因牵引而破裂出血。

In an attempt to determine non-invasively the sino-atrial conduction time, we recorded the sinus node electric activity by placing bipolar electrodes at the level of the right atrium anteroposteriorly across the chest of the dog.

本实验采用成年狗，以6极心导管电极从颈外静脉插至上腔静脉与右心房交界处，能记录到一个在心电图P波以前19—26毫秒的&P前波&。通过夹除窦房结和高血钾等实验证明，&P前波&可与P波分离而存在，并随窦房结夹除而消失。

objectiveto investigate the effect of myricetin dispersible tablets on experimental cerebral ischemia-reperfusion injury in rats and thrombosis formation.methodsexperimental cerebral ischemia-reperfusion injury model was induced by ligation bilateral common carotid arteries. the protective effect of myricetin dispersible tablets was observed by detecting the content of cerebral water, sod and mao activities,mda and la contents.

方法采用双侧颈总动脉结扎法制备大鼠实验性全脑缺血再灌注损伤模型，通过测定大鼠脑含水量，超氧化物歧化酶、单胺氧化酶的活性和丙二醛、乳酸的含量，观察杨梅素分散片对大鼠实验性脑缺血的影响；采用体内静脉血栓形成法，观察杨梅素分散片对体内静脉血栓形成的影响；并研究其对血小板聚集的影响。

Outside the neck the vein leaving alone needle inputs Austria Sha Libo, had phlebitis's influence to the patient to be light, has avoided the nerve ending damage, caused the patient easy to accept, this method was suitable for the tumor patient who carried on the chemotherapy.

颈外静脉留置针输入奥沙利铂，对患者造成静脉炎的影响较轻，避免了末梢神经损伤，使患者易于接受，该方法适用于进行化疗的肿瘤患者。
