Abstract
To explore whether dual-lumen power injectable peripherally inserted central catheters (PICCs) could be effectively and safely applied in allogeneic hematopoietic stem cell transplantation (allo-HSCT) and for serum cyclosporine level monitoring. Compared to conventional central venous access devices, PICC provides a feasible route not only for fluid infusion, but also for blood sample collection in patients undergoing oncological treatments. A prospective observational study was conducted according to the STROBE guidelines. We prospectively evaluated the applications and complications of power injectable PICCs in 52 consecutive allo-HSCT recipients. We also compared the cyclosporine levels in 188 paired blood samples, simultaneously obtained via power injectable PICCs and percutaneous venous puncture, to investigate whether power injectable PICC is a feasible route for cyclosporine concentration monitoring in allo-HSCT. The median PICC placement duration was 29days. The insertion-site blood oozing and central line-associated bloodstream infection rates were 36.5% (19/52) and 26.9% (14/52), respectively, indicating the feasibility of these PICCs for various applications in allo-HSCT. No power injectable PICC-related thrombotic adverse events were identified; 90.4% (47/52) of cases with power injectable PICC removal occurred because of lack of medical utility, suggesting that power injectable PICC-related complications were manageable. However, cyclosporine levels in samples obtained via these PICCs were significantly higher than those in samples obtained via percutaneous venous puncture (261.5±139.2 vs. 232.4±253.6ng/ml; p=0.019 [set 1]; 254.8±89.3 vs. 225.1±233.3ng/ml; p<0.001 [set 2]; 283.6±103.9 vs. 238.0±254.7ng/ml; p=0.006 [set 3]; 291.0±94.9 vs. 266.0±274.7ng/ml; p=0.016 [set 4]). The power injectable PICC is a feasible venous access device for allo-HSCT. The dual-lumen power injectable PICCs provided a reliable access for blood sample collection, decreasing the number of blind percutaneous venous punctures in allo-HSCT. However, its application in cyclosporine level monitoring needs further investigation.
