Cardiothoracic & vascular anesthesia
A Study of the Differences in Central Venous Pressure Between the Distal Lumen and Proximal Lumen of Central Venous Catheters in Pediatric Patients
Authors' conclusion
Our findings revealed no significant difference in the CVP values between the proximal and distal lumens of the CVC in small pediatric patients; moreover, the proximal lumen provided reliable CVP values, even during CPB.
Study context
- Population
- Pediatric patients with congenital heart disease, aged 1 to 31 months, undergoing cardiac surgery (Nov 2022–Nov 2023); Central venous catheter (CVC) via right internal jugular vein or right supraclavicular approach
- Participants
- 17 patients
- Exposure
- Central venous pressure (CVP) measured via distal vs proximal lumen of the CVC
- Outcome
- Difference in CVP values (A-wave pressure, X-descent pressure, mean CVP) between proximal and distal lumens
- Follow-up
- After GA induction, after CPB initiation, after weaning from CPB
Methodological detailswithin-patient comparison, simultaneous measurement
- Within-patient comparison
- Simultaneous measurement
Main finding
As reported in the abstract
A-wave pressure, X-descent pressure, mean CVP
- No statistically significant differences between distal and proximal lumens after GA induction or after weaning from cardiopulmonary bypass (CPB)
- Distal lumen significantly lower pressure than proximal lumen after CPB initiation
Observational data: associations, not effects.
