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.

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.
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.
