Application of central venous indwelling catheter guided by ultrasound in temporary hemodialysis patients / 中国医学装备

ABSTRACT

Objective:To explore the application value of central venous indwelling catheter guided by ultrasound in temporary hemodialysis patients.Methods:Seven hundred and eight cases of hemodialysis patients were choosed as the respondents who were divided into control group(n=386) and ultrasound group(n=322), sex ratio, average age, disease distribution, platelet count(Plt), prothrombin time(PT), systolic blood pressure (SBP), neck circumference was no statistical difference in two groups. In control group, indwelling catheter of the right internal jugular vein were implemented in the triangle area formed by sternocleidomastoid clavicular head, sternum, clavicle by using surface anatomic mapping. In ultrasound group, position, the diameter and blood flow filling situation of the right internal jugular vein by using ultrasound scan, the veins were punctured and indwelled catheter under the guided by ultrasound. The success rates and times of indwelling catheter, as well as complications were compared between two groups.Results: One-time success rate of indwelling catheter guided by ultrasound group was obviously higher than that of control group, the rates were statistically significant difference (x2=118.82,P<0.01), and the indwelling time was significantly shorter than that of control group, The difference was statistically significant (t=7.03,P<0.01). The puncture comfort score of ultrasound group was significantly higher than that of control group, The difference was statistically significant (t=6.29,P<0.01). The complication rate of ultrasound group was lower than that of control group, the difference was statistically significant (x2=28.24,P<0.01).Conclusion: Ultrasound help to understand the position, diameter and blood flow filling situation of the right internal jugular vein, improve the success rate of indwelling catheter and reduce the occurrence of complications.
