ABSTRACT
BACKGROUND:
Methods to determine the optimal insertion depth of ultrasound-guided supraclavicular approach to the subclavian vein (SCV) catheterization, alternatively used for central venous access, are debatable in children.AIM:
We investigated the applicability and reliability of the modified formula for determining the depth of SCV catheterization using an ultrasound-guided supraclavicular approach in children.METHODS:
This prospective observational study included 36 children (age <6 years; weight ≥5 kg) scheduled to undergo congenital heart disease surgery. After intubation, ultrasound-guided supraclavicular approach to the SCV catheterization was performed. Actual insertion depth was determined by real-time transesophageal echocardiography. Insertion depth was calculated by subtracting 1 cm 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.RESULTS:
Insertion depth calculated with the modified formula and actual insertion depth of the SCV catheter correlated strongly (r = .806, 95% confidence interval [CI] 0.658-0.908; p < .001). Bland-Altman analysis showed a mean bias and precision of 0.36 and 0.65 cm, respectively (95% CI 0.14-0.58, 95% limits of agreement -0.92, 1.64). All plots were above the -1.0 line, indicating no catheter tip insertion into the right atrium.CONCLUSIONS:
Optimal insertion depth for an ultrasound-guided supraclavicular approach to the SCV catheterization can be calculated using modification of a surface landmark formula in children younger than 6 years and weight heavier than 5 kg.Palabras clave
