Summary

Lumbar Quadrant Blockade is a recent analgesic technique consisting of the injection of local anesthetic around the lumbar square muscle. It was initially described as a technique for abdominal wall analgesia, but later studies have increased the range of indications for laparoscopic and lower limb surgeries. There are several techniques described but with differences in the literature at the point of injection and volume of anesthetic. The exact mechanism of visceral analgesia has not yet been determined. The objective of this study is to determine the dispersion of local anesthetic as a variable dependent on the volume of local anesthetic and injection site and elucidate the mechanisms of analgesia.
