Development and Validation of the Locorregional Block of the Ovarian Bursa in Bitches Undergoing Ovariectomies.

Surgical contraception in bitches is a known action towards public health and commonly performed as campaigns and collective efforts. In these events, many procedures are done so that the largest number possible of females are sterilized in a low-cost manner. The surgical contraception of female dogs is a major challenge because it is necessary access to the abdominal cavity, which means high invasiveness and painful stimuli both during and post-op, with the need of greater attention to patient and careful execution. Knowing how important it is for these campaigns to be efficient, safe and low-cost, always considering the animals welfare, this project intends to develop a new locorregional anesthesia technique of the ovarian bursa. For this project, it will be necessary three separate phases. The first one consists of determining the window of visibility of the ovaries and the sonographic anatomical characteristics of the structures in different sized bitches. The second phase will determine the volume of administration, dispersion pattern and detailed description of the needling technique for this transcutaneous block guided by ultrasound. The third and last phases will determine the efficiency of the block in live bitches undergoing ovariectomies. At the end of this research, we hope to have successfully described and validated a new local
anesthesia technique as an alternative of easy maneuver, lower cost and safer for use in these birth control campaigns.
