Complications associated with arterial catheterization in children

Area of Science:

• Pediatric critical care medicine
• Vascular access management
• Patient safety in healthcare

Background:

• Arterial catheters are crucial for hemodynamic monitoring in critically ill children.
• Complications associated with arterial catheterization can lead to significant morbidity.
• Understanding the prevalence and risk factors for these complications is essential for improving patient outcomes.

Purpose of the Study:

• To determine the incidence of arterial catheterization complications in a large pediatric cohort.
• To identify independent risk factors associated with these complications.
• To generate hypotheses for future prospective research on arterial catheter placement.

Main Methods:

• Retrospective cohort study of 10,394 pediatric patients from 33 children's hospitals.
• Inclusion criteria: age 1 month to 18 years, pediatric intensive care unit admission, arterial catheter use, and hospitalization >or=1 day post-placement.
• Complications identified via ICD-9 codes, including thrombosis, embolism, and infection.

Main Results:

• Overall complication rate was 10.3%, with infection/inflammation being the most frequent (61.8%).
• Independent predictors of complications included younger age (5-11 months, 1-2 years), later catheter insertion, cardiac surgery, bone marrow transplant, and dialysis.
• No association found with gender, Medicaid status, coagulopathy, or shock.

Conclusions:

• Arterial catheterization complications are prevalent in critically ill children.
• Limitations in ICD-9 coding prevented accounting for central venous catheterization effects.
• Further prospective studies are needed to validate findings and guide best practices for arterial catheter use.
