SUMMARY:

Techniques that promote the sterilization of female dogs are frequently used in clinical-surgical routine, with ovariohysterectomy (OVH) and ovariectomy (OVE) via celiotomy or laparoscopy being the most commonly performed. With the development of veterinary medicine, new options for less invasive and more refined techniques have emerged, contributing to the improvement of the specialty, in order to provide greater postoperative comfort, shorter surgical time, benefits to the quality of life of animals and reduction of trans- and post-surgical complications. In general, ligatures made with suture threads are used, which promote hemostasis of the vessels with various types of materials, such as absorbable or non-absorbable threads, monofilament and multifilament. Despite the good ability of sutures to promote hemostasis of vessels during OVH, the search for alternatives that present better efficiency while promoting a reduction in surgical time is growing. The objective of this study is to evaluate the effectiveness of a new device made of biomimetic polymers, capable of causing efficient hemostasis of the vessels of the ovarian arteriovenous complex and the body of the uterus, and rapid use during surgery, collaborating with a shorter surgical time and rapid postoperative recovery of the animals. To this end, OVH surgeries will be performed on female dogs, divided into two groups, where one group will receive ligatures made with polyglactin 910 suture thread (control group) and the other group will receive the biomimetic polymer device made on a 3D printer. The animals will be evaluated regarding surgical time (in minutes), marker of systemic inflammation through C-reactive protein and local tissue reaction through qualitative ultrasound evaluation in the postoperative period. Thus, it is expected that the surgical time with the use of the device will be shorter when compared to the use of suture thread, the hemostasis resulting from the use of the device will be efficient, and there will be no significant difference between the implants in the occurrence of postoperative complications.
