    Karen on our less than 10 to 15 KG kids with such as you describe, we have found we can use their double lumen Broviac to collect their stem cells. We put Cathflo/alteplase in the lumens before we start and because the volume is so low and the flow rates are slower we are able to complete the procedure. We also will use a heparin bolus 50u times their kg wt then divide the dose in half and give in each lumen prior to starting. This just helps to keep the line from clotting off since we have such low flow rates. We use the Spectra Optia machine for our Apheresis collections. If you have any other questions please feel free to reach out.

    Good evening, 
    Can you please share information re: apheresis catheter insertion/placement in infants or children less than roughly 10kg?
    1- In these small patients, do you insert apheresis catheters upfront in HR patients like Stg4 NBL or CNS tumors when you know that peripheral stem cell collection is indicated?
            If yes, do you know what brand/type/size are used?
    2-Do you insert standard catheters upfront than insert temporary pheresis catheters closer to time of collection and if so, preferred location and brand /type /size?
    Thank you in advance for your input!
