Cesariana em éguas – Estudo descritivo de 6 casos

Abstract

The objective of this study was to make a descriptive analysis of 6 cases of caesarean sections in mares. The six reported cases were treated at the Veterinary Hospital of the State University of Maringa, campus Umuarama (HVGA-UEM), from 2019 to 2021. Five Quarter Horse mares and one Crioula, complaining of prolonged delivery and dystocia due to different reasons. Of these, three cases were discharged 50% (3/6), while the other three 50% (3/6), due to postoperative complications and the severity of the clinical condition, progressed to death. Dystocia births are rare in mares, when compared to other species, this particularity, can be justified by the anatomical conformation of the reproductive system and the placental classification of mares, which provide rapid and effective contractions, which facilitate the progression of normal or eutocia birth. Thus, in cases of dystocia in mares, those in which obstetric maneuvers are unable to correct fetal malposition, cesarean section becomes the emergency procedure of choice. As a complementary measure, guided by the principles of animal welfare, owners were suggested not to place these animals in the next reproductive season, restricting their use only as embryo donors. Thus, it was possible to conclude that the survival of mares undergoing cesarean is 50% under the conditions of this study, and 100% of the fetuses had no vital signs at the time of the procedure and/or evolved to death during the post-surgical period immediate.
