Summary

Patients who have abdominal surgery will experience pain from the incision. The lumbar TAP block is a procedure used to reach the nerve endings in the abdominal wall so that there is a reduction in pain after surgery. Using ultrasound guidance, a solution of ropivacaine will be injected after surgery. The aim of this study is to determine the effect of changes in the volume of the injection.
