designate a port for blood draws from a multilumen CVAD?

I'm updating policies.

If the patient has a multi lumen catheter, should a port be designated for blood draws when the MD has ordered that blood specimens can be obtained from the CVAD?

Yes. If using a catheter

Yes. If using a catheter with staggered lumen exit port, use the one that is proximal to the hub. That way you will be drawing from above the lumens used for infusion. If non-staggered, there is probably one lumen that is larger than the others for blood drawing. Follow the catheter manufacturer's instructions for use as this is included. This book can be found inside the package of a catheter or obtained directly from the manufacturer.
