Summary
The transversus abdominis plane (TAP) block provide a local anesthesia drug diffusion between
the transverse abdominis muscle and the internal oblique muscle. TAP block reaches the
anterior rami of spinal nerves from T7 to L1 involved in the innervation of homolateral
abdominal wall. The transversus abdominis plane block has shown promise for perioperative
analgesia, but data on the optimal dose regimen are limited.Following previous research of
optimal dose of local anesthesic solution, the investigators aim to evaluate if a "volume
effect" would lead to a better diffusion of the local anesthesic solution to the overall
nervous roots. The local anesthesia drug choosen is levobupivacaine with a unique posology of
0,4 mg/kg (either 0,2 ml/kg of 0,2% levobupivacaine for "small volume" group or 0,4 ml/kg of
0,1% levobupivacaine for "high volume" group).With the same dose of levobupivacaine, this
study aims to assess the impact of volume effect on analgesia efficiency as well as the
security as after ultrasound TAP block on one to five years' old children who undergo a
peritoneal-vaginal duct surgery.
