Evaluation of the effectiveness of solutions for clearing neonatal central venous catheters: randomized study.
Carolina Mathiolli, Juliane Pagliari Araujo, Keli Regiane Tomeleri da Fonseca Pinto and 4 others
PMID 41313321WHAT IT FOUND
Saline, vitamin C and heparin cleared clot-blocked neonatal central venous catheters equally well in lab tests.
No difference was found in attempts or time, and all devices cleared.
Key findings
01Saline, vitamin C and heparin showed no statistically significant difference for clearing attempts or clearing time.
02All 30 catheters in each solution group were cleared, and the longest clearing time was 120 minutes.
03The study tested 90 removed neonatal PICC catheters in vitro, not newborns receiving care.

What it does not show
The study did not test newborns, so it cannot show safety or effectiveness in patients. Patency was checked by visible flow and saline infusion, not microscopic inspection. Catheters were stored for long periods and blocked with adult donor blood, which may not match neonatal clot occlusion. The study tested only the negative pressure technique and clot occlusion, not other occlusion types or clinical care.
The easy way to misread this
Do not use these results to choose a solution for an occluded neonatal catheter in clinical care. The study tested removed catheters in a laboratory, not newborns, so it does not show safety or effectiveness in patients.
