can midline have double lumen?
Dual lumens may be necessary in some patients but that depends upon the fluids and meds prescribed. The blood flow at the catheter tip of a midline is not the same as the blood flow in the SVC.So there could be some concern for drug contact at the catheter tip. Midlines should not be used for routine blood sampling because the tip is in the peripheral veins that have a smaller diameter.ual lumens may be necessary in some patients but that depends upon the fluids and meds prescribed.
