A Feasibility Pilot Study Assessing the Effects of External Oblique Intercostal Fascial Plane Block Versus Subcostal TAP Block for Upper Abdominal Surgery: A Randomized, Controlled Trial
The Cleveland Clinic
Summary
The investigators propose a single-center, assessor blinded, randomized control trial to compare the efficacy of external oblique fascial plane (EOIFP) block versus Oblique Subcostal Transversus Abdominis Plane (OSTAP) block for patients undergoing open upper abdominal surgery at Cleveland Clinic Main Campus.

The investigators propose a single-center, assessor blinded, randomized control trial to compare the efficacy of external oblique fascial plane (EOIFP) block versus Oblique Subcostal Transversus Abdominis Plane (OSTAP) block for patients undergoing open upper abdominal surgery at Cleveland Clinic Main Campus.. Participating patients and outcome assessors will be blinded to group assignment. The anesthesiologists who perform the blocks will not be blinded to group assignment.

Interventions
- ProcedureOblique Subcostal Transversus Abdominis Plane Block
With the OSTAP block, local anesthetic is injected into the fascial plane between the posterior rectus sheath and the transversus abdominis muscle beneath the subcostal margin.
- ProcedureExternal Oblique Intercostal Fascial Plane block
With the EOIF block, local anesthetic targets the terminal part of the thoracoabdominal nerves pass behind the costal cartilage and continue anteriorly in the plane between the internal oblique and transversus abdominis muscle, before piercing the rectus abdominis sheath as anterior cutaneous branches supplying the skin of the midabdomen.
