Values are expressed as median [IQR] and analysed using Mann-Whitney U test. *Intragroup comparison (3rd h LA, P=0.016, LAD, P=0.035 and 4th h LA, P=0.001, LAD, P=0.006). T0: on arrival to PACU, T0.5: at 30 min, T1: at 1 h, T1.5: at 1.5 h, T2: at 2 h, T2.5: at 2.5 h, T3: at 3 h, T4: at 4 h, T8: at 8 h, T12: at 12 h, T18: at 18 h, T24: at 24 h. Group LA: Total 0.5 ml/kg of 0.2% ropivacaine, Group LAD: Total 0.5 ml/kg of 0.2% ropivacaine with 1 μg/kg dexmedetomidine. CHEOPS: Children’s Hospital of Eastern Ontario Pain Scale
