[HD Cath Review](HD%20Caths.pdf) ### Short-Term (Untunneled) Catheters 300-400 ml/minute without pressure ### Tunneled Catheters A tunneled HD-CVC is different in several aspects compared with a nontunneled HD-CVC. First, a tunneled HD-CVC has a Dacron cuff that wraps around the tubing, allowing tissue integration to anchor the catheter inside the tunnel in 4 to 6 weeks and protect against pericatheter bacterial entry into the bloodstream. (Sohail et al.) Softer so potentially less vessel perf Higher flows, b/c they are larger ### Length nontunneled internal jugular HD-CVCs is considered to be the caudal superior vena cava or pericavoatrial junction,1 and catheters approximately 15 cm in length are deemed appropriate for right-sided catheters LIJ is probably best suited to at least a 20 cm line The longer the better for femoral placements ### Site R IJ is preferred site Subclavian is associated with higher risk of thrombosis [10.1093/ndt/6.10.722] Femoral works better if actually in the IVC ### Can you place 2 caths in the same Vein? vein in the intensive care setting: is it safe?
