Retrospective evaluation of anaesthesia management in children with CHD undergoing procedures in the paediatric cardiology catheterization laboratory.

In this cohort, general anaesthesia was associated with higher recorded complication rates than sedation, and this association persisted after adjustment within diagnostic catheterizations.

Comparisons within interventional procedures were limited by sparse sedation data. These findings support procedure-specific, risk-adjusted evaluation when selecting anaesthesia strategy in the paediatric catheterization laboratory.
