EMRAPTV Episode 56: Central Lines A summary of the types of central lines and how not to screw up from USC Grand Rounds.

But the method you've talked about for securing CVCs is a real safety issue with central lines in ICU or the wards. You should never use the white/blue clip on device to secure the CVCs as you can easily pull a central line out (under the weight of infusion lines or patient movement,etc) with that clip on. Better to secure the line to the skin with silk sutures both at the point where the line goes into the skin and again at the fixed hub at the distal part of the line. There's a number of techniques to do that. Ditto if you only secure the distal hub and have left a length of the line outside the skin, it's easy to pull the line out whilst your sutures stay attached.
Lines secured using the clips come out quite frequently and result in complications for the patient (eg large volumes of infusions into the subcut tissue of the neck causing airway compromise or tissue necrosis due to the drug infused).
When patients come into our ICU with those clips we make it a priority to secure the line properly to save on mortality and morbidity for our patients.
