Study Arms (3)

Control Group

ACTIVE COMPARATOR

Patients will receive no block intervention and standard intravenous analgesia will be given.

Other: Standard intravenous analgesia

STIL block

EXPERIMENTAL

Patients will receive ipsilateral ultrasound-guided subtransverse process interligamentary (STIL) plane block with bupivacaine 0.25% (0.5 mL/kg) after induction of general anesthesia.

Other: Subtransverse process interligamentary plane block

RISS block group

EXPERIMENTAL

Patients will receive ipsilateral ultrasound-guided rhomboid intercostal block (RIB) combined with sub-serratus plan block group with bupivacaine 0.25% (0.5mL/kg) after induction of general anesthesia.

Other: Rhomboid intercostal block (RIB) combined with sub-serratus plan block group

Interventions
