RESUMO
Objective To observed the clinical efficacy and safety of high pressure-resistant double-lumen peripherally inserted central catheter (Power PICC) and central venous catheter (CVC) in patients with stem cell transplantation.Methods This was a matched cross-sectional study with 60 patients with leukemia who were treated with catheterization of central venous (30 cases receiving Power PICC vs.30 cases receiving CVC) during stem cell transplantation in the First Affiliated Hospital of Chinese PLA General Hospital.Indwelling time,success rate of catheterization,complications,velocity and stem cell engraftment time were recorded and compared between the Power PICC group and CVC group.Results There were significant differences between the two groups on indwelling time [(18.47±4.44) min vs.(14.43± 1.72) min,t =3.719,P＜0.001],complications [6.67％ (2/30) vs.30％ (9/30),x2 =48.445,P=0.002] and velocity.However,no significant difference was found in success rate of catheterization and stem cell engraftment time (P＞0.05).Conclusion Power PICC performed better than CVC with well tolerability and satisfactory efficacy,which is worthy of promotion and application in the future.
