Effects comparison between ultrasound-guided peripherally inserted central catheter under modified Seldinger technique and traditional PICC

Objective To compare the effect of ultrasound-guided peripherally inserted central catheter(PICC) under modified Seldinger technique and traditional PICC. Methods 280 cases of outpatients and inpatients required PICC in Central Hospital Affiliated to Shenyang Medical College from June 2010 to December 2013 were randomly divided into two groups, each of 140 cases. Patients of study group were given ultrasound-guided PICC on upper arm under modified Seldinger technique, and patients in control group were given traditional PICC. One time puncture success rate,one time catheter success rate, total catheter success rate, the usage condition of basilic vein, tip position of catheter,and related complications of two groups were observed and compared. Results The one time puncture success rate, one time catheter success rate, total catheter success rate of study group were significantly higher than those of control group(99.3%, 97.8%, 99.3% vs 80.0%, 77.8%, 88.6%), the differences between the two groups were statistically significant(χ2=6.395, 6.843,4.283, P 0.05). The usage condition of puncture veins and tip position of catheter were compared between the two groups, the differences were statistically significant(χ2=7.209, 4.375, P 0.05). Catheter indwelling time of study group was longer than the control group [(162±20) d vs(124±17) d](t=5.794, P 0.05). The occurrence rates of phlebitis, venous thrombosis, peripheral tissue damage of study group were significantly lower than those of the control group(P 0.05), occurrence rates of puncture point bleeding, catheter-related infection between the two groups had no significantly different(P 0.05). Conclusion Ultrasound-guided PICC under modified Seldinger technique can effectively improve the success rate of puncture and catheterization, reduce the incidence of catheter-related complications and ectopic catheter, had high security, which should be widely applied.
