ABSTRACT
BACKGROUND:
Leukapheresis procedures require adequate flow rates, which in children may frequently involve invasive vascular access placement. STUDY DESIGN ANDMETHODS:
A minimally invasive peripheral radial artery catheter was used for drawing blood in 85 leukapheresis procedures performed in 33 pediatric patients. Blood return to the patients was provided by either a central Broviac-type catheter or a peripheral venous access. The patients' age range was 1 to 18 years (median, 9.5) and the weight range was 9 to 73 kg (median, 29 kg). Vasocan Braunüle Luer Lock IV cannulas (22 gauge in 78 and 20 gauge in 7) were placed percutaneously under local anesthesia, and in 8 patients, catheter placement was carried out during general anesthesia for other procedures. A continuous flow cell separator was used in all cases (Fresenius AS104 in 23 and AS204 in 62).RESULTS:
Flow rates ranged from 18 to 45 mL per minute, the mean number of total blood volumes processed was 2.07 (range, 0.51-2.51), and the mean duration of the procedures was 150 minutes (range, 90-260). The 22-gauge cannulas provided adequate flow rates independently of patient age and weight. No significant thrombotic, embolic, hemorrhagic, ischemic, or infectious complications were observed.CONCLUSION:
Peripheral radial artery catheters are safe, are minimally invasive, and provide steady, high-flow rates, and they should be considered for patients requiring leukapheresis and lacking a suitable vascular access for drawing blood.
