The application of PICC catheterization with modified Seldinger technique under the guidance of ultrasound in cancer patients

Objective To compare the effect of modified Seldinger technique under the guidance of ultrasound for peripherally inserted central venous catheter(PICC) catheterization with the traditional method of PICC catheterization.Methods Sixty patients with late stage malignant tumor performed regular PICC catheterization were randomly divided into control group and observation group,30 cases in each group.Patients in control group were applied with conventional catheter puncture method under naked eyes,and patients in observation group were applied with modified Seldinger technique for PICC catheterization under the guidance of ultrasound.The successful rate of puncture and incidence rates of catheter escape,hemorrhage,subcutaneous ecchymosis,phlebitis and thrombosis were compared between these 2 groups.Results The successful rate in observation group was significantly higher than that of control group.The incidence rates of catheter escape,hemorrhage,subcutaneous ecchymosis,phlebitis and thrombosis were significantly lower than those of control group(P0.05).Conclusion The PICC catheterization with modified Seldinger technique under the guidance of ultrasound has higher successful rate with less complications and high safety and reliablity.
