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.
subcostal transversus abdominis plane block
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.
External Oblique Intercostal Plane Block
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.
external oblique intercostal plane block and subcostal transversus abdominis plane block combination
The combination of the two blocks will be applied in 15 ml of volume for each.
