Clinical significance of the cross-sectional area of internal jugular vein and peripherally inserted central catheter by real-time ultrasound-guiding in infants with congenital heart disease

Objective: To evaluate the clinical value of real-time ultrasound-guiding right internal jugular vein catheter in infants with congenital heart disease. Methods: Seventy-six infants with congenital heart disease scheduled by right internal jugular vein catheter were randomly divided into the anatomic mark localization group( group A) and real-time ultrasound-guiding localization group( group B)( 38 cases each group). The one-time puncture success rate,total puncture success rate,average number of puncture,puncture failure rate and complications in two groups were recorded. Results: The one-time puncture success rate in group B was significantly higher than that in group A( P 0. 01). The difference of the total puncture success rate between group A and B was not statistically significant( P 0. 05). The number of puncture and incidence of mistaken puncturing into carotid artery in group A were significantly higher than those in group A( P 0. 01). The difference of the incidence of local hematoma between group A and B was not statistically significant( P 0. 05). Conclusions: The real-time ultrasound-guiding right internal jugular vein catheter in infants with congenital heart disease can significantly improve the one-time puncture success rate,decrease the number of puncture and incidence of mistaken puncturing into carotid artery,which has the high practical value in clinic.
