Simplified CVC Confirmation

Central lines are often needed in the sickest patient, and after we place them, we usually need to use them quickly. Traditionally, this means tapping your foot anxiously while waiting for a chest xray to confirm that the catheter is in the appropriate place. Well guess what - it turns out that ultrasound is pretty good at determining correct placement, at the bedside, right away. This study attempts to use a simplified flush protocol to see how accurately and how quickly ultrasound can confirm catheters placed in the internal jugular or subclavian veins.
