Objective: To evaluate the ultrasound dampening effect of the different types of meshes abdominal surgery after implantation in Wistar rats.

Method: We used two Wistar rats, assessed positions and different types of meshes. The animals were anesthetized prior to surgery to open the abdominal cavity for placement of the prosthesis. Divided into three stages, 1) analysis of the abdominal cavity with ultrasound and no mesh 2) onlay position (mesh placed anterior the abdominal muscles) 3) underlay (intraperitoneal) for the posterior muscular. The meshes were used polypropylene (PP), polyester (PE), polypropylene/poliglecaprone (PU), polytetrafluoroethylene condensate (MO), polyester/ collagen (PC) and polypropylene/polydioxanone/oxidized regenerated cellulose (PRO). The animals were euthanized after the procedure.

Results: There was no need to exclude the animals. The initial assessment showed no areas of difficulty or ease that would harm the exam. In all analyzes there was no problem identifying the the skin and subcutaneous tissue. There was a statistically significant difference in the attenuation of the meshes in both the onlay position p<0.001. Underlay position there was a small improvement in the graduation, with PE median (min-max) of 3 (2-5), PP, PU with 2 (1-5) and PC 2 (2-5) followed by PRO mesh with 1 (2-5) and MO with 0 (0-5) with statistical significance at p=0.001. However there was no comparison to the same mesh in two positions on the all meshes.

Conclusion: All types of meshes used in this study was independent of the position of the sound degree attenuation in ultrasound examination. The polyester mesh got to take a lower degree of attenuation compared with other meshes of the study. Is needed a new test to check the attenuation in the long term.
