The impact of anaesthesia on lung function during paediatric surgery remains an area of active investigation. Understanding respiratory mechanics under different anaesthetic approaches is crucial for optimising pulmonary management in this vulnerable population. To assess ventilation distribution changes during different phases of anaesthesia in paediatric patients, using electrical impedance tomography (EIT). This observational study included 76 paediatric surgical patients-57 under controlled mechanical ventilation (CMV) and 19 breathing spontaneously. EIT assessed lung ventilation at multiple timepoints (T1-T6), analyzing regional distribution (ROIs) and center of ventilation (CoV). In the CMV group, ventilation progressively shifted toward ventral lung regions (p
