由于颈内静脉在颈部的解剖位置恒定。多数以胸锁乳突肌作为标志,颈动脉和颈内静脉本身也可触及。但在麻醉后及肥胖病人,尤其是在心跳骤停患者,上述标志很难确定,为此作者提出了根据骨性标记施行颈内静脉穿刺的一种新方法,并对134例患者应用该法进行前瞻性研究。 134例需置肺动脉导管的腹部手术患者,男性96例,女性38例,年龄21～84岁。麻醉诱导后行机 Due to the constant internal anatomy of the internal jugular vein in the neck. Most of the sternocleidomastoid as a sign, carotid and internal jugular vein itself can be reached. However, these signs are difficult to determine after anesthesia and in obese patients, especially in patients with cardiac arrest. To this end, the authors propose a new method of performing jugular vein puncture with a bony marker, and apply the method to 134 patients Prospective study. In the 134 patients undergoing abdominal surgery requiring pulmonary catheterization, there were 96 males and 38 females, aged 21-84 years. Anesthesia after induction machine
