Evaluating The Quality of Recovery After Elective Cesarean Section

"The curvilinear probe (2 5 MHz, SonoSite Turbo M) is placed in the transverse axial plane just cranial to the iliac crest. The shamrock sign was visualised (viz., the transverse process (TP) of vertebra L4 is the stem, whereas the erector spinae muscle (ESM) posteriorly, quadratus lumborum (QL) muscle laterally and the psoas major (PM) muscle anteriorly represent the three leaves). The needle is introduced using an in plane technique from the posterior end of the transducer through the QL muscle. The target for injection is the fascial plane between the QL and PM muscles.."
