A comparative Study Between Ultrasound Guided Oblique Subcostal Block Versus Posterior TransversusAbdominis Plane Block For Pain Relief in Children Undergoing Abdominal Explorations

Abstract

The use of ultrasound for the placement of peripheral nerve blocks has received a great deal of attention lately in the anesthesiology literature and is beginning to solidify a place in clinical practice. Claimed benefits of ultrasound-guided regional anesthesia include that it is easier to learn and quicker to perform, has a faster onset, results in higher success rates, results in more complete blocks, requires lower volumes of local anesthetic and increases safety. Asubstantial component of the pain experienced by patients after abdominal surgery is derived from the abdominal wall incision. The abdominal wall is innervated by nerve afferents that course through the transversusabdominisneuro-fascial plane.
