Slow injection rate of 2ml s -1 only minimally compromise the image quality. Localizing the the position of CVC before and after the injection Safety protocols when using CVC as intravenous contrast injection site are 5:Īspirating blood before the injection of contrast media Automatic power injection or hand injection of contrast media poses the same risk of catheter rupture 4. Among the complications are 4:Ĭatheter rupture leading to contrast extravasationĬatheters more than 3 months old have increased risk of rupture. Guidewire shearing and fragment embolizationĬontrast injection through a central venous catheter is safe with complication rate of 1% if a strict protocol is followed. In the setting of triple lumen catheter placement there are 3 potential insertion sites the internal jugular, subclavian, or femoral vein. Ultrasound-guided CVL insertion is proposed to reduce the number of complications and to increase the safety and quality of central venous catheter (CVC) placement. There is a limited differential of left paramediastinal catheter positions. Policy varies by institution but tip placement for neck/thoracic/upper limb CVCs in the superior vena cava or at the cavoatrial junction is generally acceptable. ![]()
