E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We have recently described the Transversus Abdominis Plane (TAP) Block, a reliable approach to the blockade of the neural afferents to the anterior abdominal wall.The lumbar triangle of Petit is a potential access point to this neurofascial plane. Therefore, by introducing local anesthetic agents into this space via the triangle of Petit it is possible to block the sensory nerves of the anterior abdominal wall before they pierce the musculature to innervate the abdomen. We aim to determine the analgesic efficacy of TAP blockade in the first 24 postoperative hours, in children undergoing abdominal surgery via an abdominal wall incision, in a randomized controlled double blind clinical trial. Primary Measures: Severity of Postoperative Pain [VAS and Categorical pain Scales] Total opiate usage in the first 24 hours after surgery

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
We have recently demonstrated the analgesic efficacy of the TAP block in adults undergoing abdominal surgery. Based on this study, in order to demonstrate a difference of 25% in post-operative total analgesia consumption following abdominal surgery, at the 0.05 level of significance with a power of 0.8, we will require a minimum of 25 patients in each group. It is therefore planned to recruit 60 patients in total. |
