The present study is aimed at establishing the values of internal jugular vein (IJV) anterior-posterior and medial-lateral sizes in patients with hypovolemia. A total of 25 adult Intensive Care Unit patients with hypovolemia were studied. It was found that the anterior-posterior vein size in patients with hypovolemia was significantly less than medial-lateral size during inhalation and during exhalation as well ( < 0.05). Besides, the value of the anterior-posterior size (D) <7 mm was recorded in 20 from 25 patients (80%). At the same time, the medial-lateral size (D) <7 mm was recorded only in six patients (24%). In patients with hypovolemia, the medial-lateral diameter of IJV is more than its anterior-posterior diameter. These data might be useful for justifying the benefits of using lateral access for IJV catheterization under ultrasound imaging in patients with hypovolemia.
本研究旨在确定低血容量患者颈内静脉（IJV）前后径及内外径的数值。共对25例成年低血容量重症监护病房患者进行了研究。结果发现，低血容量患者在吸气及呼气时的静脉前后径均显著小于内外径（<0.05）。此外，25例患者中有20例（80%）记录到前后径（D）<7mm。同时，仅6例患者（24%）记录到内外径（D）<7mm。在低血容量患者中，颈内静脉的内外径大于前后径。这些数据可能有助于证明在超声成像引导下对低血容量患者采用颈内静脉外侧入路进行置管的益处。
