Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1: subcostal transversus abdominis plane block

This group will receive 30 ml 0.25% of bupivacaine for the subcostal transversus abdominis plane block prior to surgery.

Group Type ACTIVE_COMPARATOR

subcostal transversus abdominis plane block

Intervention Type PROCEDURE

Under ultrasound guidance, 30 ml of bupivacaine is injected along the fascia of transversus abdominis muscle.

Group 2: external oblique intercostal plane block

This group will receive 30 ml 0.25% of bupivacaine for the external oblique intercostal plane block prior to surgery.

Group Type ACTIVE_COMPARATOR

External Oblique Intercostal Plane Block

Intervention Type PROCEDURE

Under ultrasound guidance, 30 ml of bupivacaine is injected between the fascias of external oblique and intercostal muscles.

Group 3: subcostal transversus abdominis and external oblique intercostal plane block combination

This group will receive 15 ml 0.25% of bupivacaine for the external oblique intercostal plane block, in combination with 15 ml 0.25% of bupivacaine for the subcostal transversus abdominis plane block prior to surgery.

Group Type ACTIVE_COMPARATOR
