Study on the application value of B ultrasound-guided seldinger technique for PICC in patients with difficult indwelling catheter

Objective To study the application value of B ultrasound-guided seldinger technique for PICC in patients with difficult indwelling catheter.Methods Forty-three patients with difficult indwelling catheter who did not undergo B ultrasound-guided seldinger technique for PICC in our hospital from March 2012 to September 2012 were selected as the control group,and 43 patients who received B ultrasound-guided seldinger technique for PICC at the same time were selected as the observation group.Then the one-time success rate,two-time success rate,total success rate,blood loss,position of the end of PICC,retention time,incidence of complications during and after the indwelling were compared between the two groups.Results The one-time success rate,two-time success rate,total success rate in the observation group were all significantly higher than those in the control group,The observation group also had significantly higher optimal rate of the position of the end of PICC,less blood loss,longer retention time,and lower incidence of complications,P0.05.Conclusion B ultrasound-guided seldinger technique has high application value of for PICC in patients with difficult indwelling catheter.
