After intubation, ultrasound\u2010guided supraclavicular approach to the SCV catheterization was performed. Actual insertion depth was determined by real\u2010time transesophageal echocardiography. Insertion depth was calculated by subtracting 1\u00a0cm from the sum of the distance from the insertion point to the sternal head of the right clavicle and that from the latter point to the midpoint of a perpendicular line drawn from the sternal head of the right clavicle to the line connecting the nipples.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Insertion depth calculated with the modified formula and actual insertion depth of the SCV catheter correlated strongly (<jats:italic>r<\/jats:italic>\u00a0=\u00a0.806, 95% confidence interval [CI]: 0.658\u20120.908; <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001).
