Upper Abdominal Surgeries

This study evaluates respiratory recovery as a multidimensional construct using clinically relevant and measurable parameters, including LUS, diaphragmatic excursion, oxygen requirement, and PPCs. The investigators hypothesize that bilateral ESP block improves postoperative respiratory function compared with EOIP block following open hepatic surgery. The investigators further hypothesize that this improvement is mediated, in part, by superior analgesia.

This study aims to compare between ultrasound guided external oblique intercostal plane block and ultrasound guided erector spinae plane block in paediatric upper abdominal surgeries.
