  Description
Landmark Guided In the landmark technique, the subclavian vein or the internal jugular vein on either side was chosen for access depending on surgeon’s preference. An infraclavicular approach was used for the subclavian vein, and an anterior approach was used for the internal jugular vein. If venous flash could not be achieved after three attempts on the initial chosen site using the landmark technique, the study was terminated and the surgeon was free to use either ultrasound or landmark at any other site. A single pass of the needle was defined as a single episode of needle advancement and withdrawal. A second pass occurred if the needle was re-advanced or removed and reinserted. A failed attempt was recorded if aspiration resulted in no venous flash, arterial puncture (bright red blood, pulsatile flow), or air.
Ultrasound Guided In the ultrasound-guided group, the internal jugular vein on either side was accessed depending on surgeon’s preference. An ultrasound console with a linear 11 Hz probe was used. The patient was then put into Trendelenburg position. The head was positioned away from the insertion side. The ultrasound probe was placed at the apex of the triangle formed between the two heads of the sternocleidomastoid muscle and the clavicle. The internal jugular vein and common carotid artery were visualized, with the vein identified by its larger size, relative anatomic position, and compressibility. After a flashback of dark venous blood was noted in the syringe, the standard Seldinger technique was followed for the catheter insertion. After 3 failed attempts using the ultrasound at the specified site, the surgeon was free to further attempts using landmark or ultrasound approaches at any other site.

Reporting Groups
  Description
Landmark Guided All patients between the ages of 0 and 18 years undergoing tunneled central venous line placement under general anesthesia were approached for inclusion in the study. Children known preoperatively to have non-patency of central veins or coagulopathy were excluded from the study. Patients with previous multiple line placements were screened for deep venous thrombosis using Doppler ultrasound. Patients were enrolled by a member of the study team, and informed consent for the study was obtained from the patient’s legal guardian.
