Objective  To observe the clinical effect of peripherally inserted central catheter(PICC) by tunneling through the internal jugular vein with No.9 scalp needle.

  Methods  Sixty patients who received PICC to establish venous access were selected as research objects, and were divided into control group and experimental group by random number table method, with 30 cases in each group. In the control group, central venous catheter (CVC) was inserted through the subclavian vein, while in the experimental group, tunnel PICC was inserted through the internal jugular vein with No.9 scalp needle under ultrasonic guidance. The success rate of one-time puncture and operation pain, catheter indwelling time, incidence rate of the unplanned extubation and related complications were compared.

  Results  The success rate of one-time puncture of the experimental group was higher, operation pain score and unplanned extubation rate of the experimental group were significantly lower than those of the control group, catheter indwelling time was longer than that of the control group(P < 0.05). There was no significant difference in the degree of bleeding between the two groups (P>0.05). The incidence rates of catheter-related infection, catheter displacement and catheter blockage in the experimental group were lower than those in the control group (P < 0.05).

  Conclusion  No.9 scalp needle can reduce catheter-related infection, prolong catheter indwelling time, and provide a safe, economic and effective venous access for patients with PICC by tunneling through the internal jugular vein.
