Pediatric anesthesia & critical care
Immediate complications and risk factors following radial arterial catheterisation in paediatric patients at a tertiary centre
Authors' conclusion
Most immediate complications following radial arterial catheterisation in paediatric patients resolved spontaneously by postoperative day 5. The Medicut-to-artery diameter ratio and prolonged anaesthesia were significant risk factors for complications.
Study context
- Population
- Children aged 5 years or younger scheduled for elective surgery with ultrasound-guided radial artery cannulation, tertiary children's hospital
- Outcome
- Incidence of complications associated with arterial catheterisation after decannulation, assessed by ultrasonography
- Follow-up
- Immediately after catheter removal
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Immediate complications after decannulation (thrombus formation, significant arterial stenosis), by ultrasound
Incidence of immediate complications
41.5%
Observational data: associations, not effects.

Perfusion index and immediate complications
- Perfusion index values not associated with immediate complications
Arterial size reduction · 24 h postdecannulation
- Greater arterial size reduction persisted in patients with immediate complications
Arterial diameter · POD 5
- Arterial diameters spontaneously improved significantly
Safety
Clinical complications · POD 5
- No clinical complications observed
