Abstract
Objective To discuss the influence of different puncture methods of Seldinger technique under B-scan on PICC success rate. Methods Review the clinical data of 90 patients who were treated by Seldinger technique in our hosipital from September 2012 to September 2013,90 patients were randomly divided into two groups by hidden-digital classification,45 cases of the control group used conventional puncture method of Seldinger technique,45 cases of the observation group used improved puncture method of Seldinger technique, trocar was slowly thrusted to the target vascular in a 45 ° angle with skin, released the puncture needle when B-scan showed the vascular had been oppressed,after the vascular was reconstruction, then adjusted position of needle and reelingly thrusted to the target vascular,wihdrawed the core needle and inserted a guide pin.Compare the success rate of puncture,bleeding of puncture point,incidence of Phlebitis. Results The success rate of observation group was 86.67%,the control group was 68.89%,the difference was Statistically significant(P<0.05). Conclusion Improved puncture method is benefit to improve the success rate of PICC tube.关键词
