Effect comparation of PICC insertion guided by vascular ultrasound combined with modified seldinger technique with the traditional method in elderly patients with Alzheimer′s disease

Objective To compare the effect of modified seldinger technique under the guidance of ultrasound for PICC inserttion with the traditional method of PICC catheterization(14 G needle insertion of PICC)in elderly patients with Alzheimer’s disease.Methods 60 patients with AD were divided into observation group applying PICC insertion with US and MST and con-trol group with traditional method of PICC catheterization with 30 patients in each group.The suc-cess rates of the only one puncture,catheter indwelling time and the incidence of complications dur-ing catheter indwelling were compared between the two groups.Results There were 22 patients with 7 to 12 months catheter indwelling time and 8 patients with more than 12 months in observa-tion group.There was 1 patient for 1 to 3 months catheter indwelling time,11 patients for 4 to 6 months,7 patients for 7 to 12 months and 1 patient for more than 12 months in control group.Ac-cording to the results,the difference was statistically significant(P <0.05).The successful rate of the only one puncture in observation group was 96.7% while only 53.3% in control group.So the difference was statistically significant(P <0.05).The incidence of complications during catheter indwelling was 6.7% in observation group and 50% in control group.Thus,the difference was statistically significant(P <0.05).Conclusion The PICC catheterization with modified seldinger technique under the guidance of vascular ultrasound has higher successful rate and less incidence of complications.So it is worthy of widely application.
