颈内静脉穿刺术广泛用于临床的治疗、监测、抢救等,由于在解剖学上存在的差异,传统的穿刺以右侧应用较多,而应用左侧颈内静脉穿刺较少,在某些情况,如局部疤痕、肿瘤化疗已有过数次穿刺置管用药史等,能否避开右侧,有意识的选择左侧进行穿刺,似更为合理。但与右侧相比,左颈内静脉穿刺的主要顾虑是担心误伤胸膜或胸导管引起的气胸、乳糜胸等并发症,一旦发生均需认真处理。传统颈内静脉穿刺多依靠体表解剖标志及动脉搏动点定位,
Because of the differences in anatomy, traditional puncture to the right side of the application more, while the application of the left jugular vein puncture less, in some Circumstances, such as local scarring, cancer chemotherapy have several times the history of puncture catheterization, etc., can avoid the right side, the left side of the conscious choice for puncture, seems more reasonable. However, compared with the right side, the main concern of left jugular venipuncture is the complication of complications such as pneumothorax and chylothorax caused by accidental injury to the pleura or thoracic duct. Traditional internal jugular vein puncture rely on surface anatomy signs and arterial pulse point positioning,
