Cannulation of internal jugular vein in neutral head position

An approach to cannulate right internal jugular vein in neutral head position is described for situations where head rotation and extension are contraindicated. Venous puncture was made immediately lateral to the carotid artery at the level of cricoid cartilage and directed caudad. In 40 patients studied, the right internal jugular vein of 97.5% of the patients were successfully located by the finder needle. The mean (SE) number of puncture attempts to locate the vein was 1.3 (0.1) per patient. In 72.5% (29 patients), the veins were located exactly at the predicted point after the first attempt. However the overall success rate for cannulation by the angiocath cannula was 87.5% and short term complication rate was 5.0%. We conclude this technique is a reliable, safe alternative for central venous access, especially in patients where cervical spine movement is contraindicated or restricted.
