Various methods have been recommended to decide a proper insertion depth of central venous catheter (CVC). The carina is recommended as a useful target level for the CVC tip position. We evaluated the sternal head of a right clavicle and the nipples as anatomic landmarks for determining the optimal depth of CVC in paediatric patients. ⋯ The CVC tip could be placed near the carina by using the external landmarks without any formulae, images, and devices in children in our study.
