Abstract

IJV is most commonly used for central venous access as it is superficially located and fewer incidences of serious complications like pneumothorax and haemothorax compared with subclavian approach. The most common complication during IJV cannulation is accidental rupture of CCA. A cross-sectional study was performed on 100 patients coming to hospitals attached to Bangalore Medical College and Research Institute, Bengaluru. USG neck was performed to obtain the images of IJV and CCA on both sides with respect to different head rotations angles (0°, 15°, 30°, 45°, 60°, 75° and 90°) and results were calculated. Most common position of IJV is anterolateral with respect to CCA at any given head rotation angle. On turning head to contralateral position, IJV is noted displaced to anterior position. Percentage overlap of IJV to CCA significantly increases when head rotated >45° at 2 cm above the clavicle and > 30° at 4 cm above the clavicle.
