We recommend a selective approach to NMB in paediatric abdominal surgery, avoiding deep NMB (posttetanic count: 1 to 2 responses) for minor procedures (e. g. inguinal hernia repair), and establishing deep NMB for major procedures (e.g. hepatobiliary surgery) when necessary. Deep NMB should be considered for enhancement of surgical conditions and ventilation when indicated. （Conditional recommendation based on moderate level of evidence）

We suggest that NMB can improve surgical and ventilation conditions when a second-generation SGA is used for abdominal surgery. (Conditional recommendation based on low level of evidence)

We recommend quantitative neuromuscular monitoring whenever an NMBA is used to modulate the level of neuromuscular block and to rule out residual NMB before extubation. （Strong recommendation based on moderate level of evidence）

We recommend quantitative neuromuscular monitoring whenever an NMBA is used to modulate the level of neuromuscular block and to rule out residual NMB before extubation. （Strong recommendation based on moderate level of evidence）

We suggest neuromuscular monitoring at the adductor pollicis site as the first choice and the flexor hallucis brevis as an alternative if the adductor pollicis site is not accessible. ( Conditional recommendation based on very low level of evidence)

We suggest quantitative electromyography-based rather than acceleromyography-based neuromuscular monitoring and calibrating the device before administering an NMBA. （Conditional recommendation with very low level of evidence）

We recommend sugammadex over neostigmine for the reversal of aminosteroid NMB in children due to its faster recovery time, shorter time to extubation and more effective reversal of moderate and deep block. （Strong recommendation with moderate level of evidence）

In children under the age of 2 years, sugammadex can be safely used for reversal of aminosteroid NMBAs at the same dose per kg bodyweight as in older children and adults. （ Strong recommendation with moderate level of evidence）

To prevent residual NMB or recurarisation, we suggest avoiding excessive doses of rocuronium and using systematic quantitative neuromuscular monitoring to ensure adequate recovery before extubation. （Conditional recommendation based on very low level of evidence）

In children aged less than 2 years or when a large total dose of rocuronium or vecuronium has been used, we suggest an extended observation period in PACU if sugammadex was used for reversal. （Conditional recommendation based on very low level of evidence）
