Complications of vascular catheterization in critically ill children
Insights
Vascular catheterizations in critically ill children can cause complications like bleeding and sepsis, especially in those under 5. However, the study suggests the benefits outweigh the risks for these vulnerable patients.
Area of Science:
- Pediatric Critical Care Medicine
- Vascular Access Procedures
Background:
- Invasive hemodynamic monitoring is crucial for critically ill children.
- Vascular catheterizations are common but carry potential risks.
Purpose of the Study:
- To prospectively evaluate the incidence and types of complications associated with vascular catheterizations in critically ill children.
- To assess the risk-benefit ratio of these procedures in pediatric intensive care.
Main Methods:
- Prospective study of 467 children undergoing arterial, central venous, and pulmonary artery catheterizations.
- Detailed recording of catheter types, numbers, and associated complications.
- Analysis of complication rates stratified by age and procedure type.
Main Results:
- 19 complications (bleeding, arterial obstruction, sepsis) occurred in 4.1% of children.
- Complications were more frequent in children under 5 years old (71% of noted complications).
- Overall mortality in the study group was 16%.
Conclusions:
- Vascular catheterizations are associated with a low but significant risk of morbidity in critically ill children.
- The risk of complications appears justified by the clinical benefits in this high-risk population.
- Younger children (<5 years) represent a higher-risk group for catheter-related complications.
Abstract:
Invasive hemodynamic monitoring is widely used in the care of critically ill children. In a prospective study, a total of 330 arterial catheters, 397 central venous catheters, and 47 pulmonary artery catheters were placed in 467 children, between February 1981 and September 1982. Complications observed included: bleeding in seven of 774 vascular catheterizations, arterial obstruction in three of 377 arterial catheterizations, and sepsis in 11 of 774 vascular catheterizations. Of the 21 complications noted, 71% occurred in children less than 5 yr of age. A total of 19 (4.1%) children suffered complications of bleeding, arterial obstruction, and/or sepsis. In contrast, the overall mortality in this group of patients was 16%. The risk of morbidity from vascular catheterization appeared justified in this group of critically ill children.
