Application of ultrasound-guided central venous catheterization at various sites in infants with shock / 中国当代儿科杂志

ABSTRACT

OBJECTIVES@#To study the clinical characteristics of ultrasound-guided central venous catheterization at various sites in infants with shock, and to explore how to quickly select the site for central venous puncture in infants with shock.@*METHODS@#The medical data of 112 infants who were diagnosed with shock and underwent central venous catheterization in the Pediatric Intensive Care Unit, Dongguan Children's Hospital Affiliated to Guangdong Medical University, from January 2016 to December 2020 were reviewed retrospectively. The patients were divided into an ultrasound group (n=70) and a body surface location group (n=42) according to whether the catheterization was carried out under ultrasound guidance. The application of ultrasound-guided catheterization at various sites in infants was summarized and analyzed, and the success rate of one-time puncture, overall success rate, catheterization time, and complications were compared between these sites.@*RESULTS@#Compared with the body surface location group, the ultrasound group had a significantly higher success rate of one-time puncture, a significantly shorter catheterization time, and a significantly reduced incidence rate of complications in internal jugular vein and femoral vein catheterizations (P<0.05). In the ultrasound group, the proportion of internal jugular vein catheterization was the highest (51%, 36/70), followed by femoral vein catheterization (33%, 23/70), and subclavian vein catheterization (16%, 11/70). For the comparison between different puncture sites under ultrasound guidance, internal jugular vein catheterization showed the shortest time of a successful catheterization [5.5 (5.0, 6.5) minutes] (P<0.05). There was no significant difference in the incidence rate of complications among the different puncture sites groups (P>0.05).@*CONCLUSIONS@#In infants with shock, ultrasound-guided internal jugular vein catheterization can be used as the preferred catheterization method for clinicians.
