Ultrasound-guided Transverses Abdominis Plane Block in Inguinal Herniorrhaphy: Randomized Controlled Clinical Trial

Acute postoperative pain is one of the most important centers of therapeutic attention in postoperative phase of any procedure. It is a complex entity that requires a multiple intervention to be treated and, depending on the intervened surgical site, it has different approaches. Despite attempts to reduce postoperative pain by implementing management protocols, rates of pain prevalence from moderate acute to severe pain are still reported as high as 50% in the first 24 postoperative hours. Among the surgeries that report greater intensity of postoperative pain is open inguinal Herniorrhaphy. That is why several techniques have been described for the management of acute pain in this surgery postoperative, among which PAT blocking has shown to be beneficial in some studies. However, some reports question its usefulness but with the emergence of ultrasound-guided techniques for its realization, interest in this blockage has grown back. This study aims to demonstrate the utility of the PAT blocking in the management of acute pain of pre-peritoneal inguinal herniorrhaphy with mesh.
