The concentrations of acute phase proteins are correlated with the severity of the surgical trauma, being elevated when severe tissue injury is produced. The aim of this study was to evaluate the leukogram and the acute phase proteins concentrations in healthy female dogs submitted to minimally invasive ovariohysterectomy, with the use of nylon cable ties (G1), and conventional (laparotomy) ovariohysterectomy, with the use of nylon suture (G2), as methods to ligate the ovarian pedicles and uterine body, respectively. Blood samples from 30 adult healthy female dogs (15 for each group) were obtained before surgery, and at 24 and 48 h and 7 days after surgery. Serum protein fractions were determined by means of sodium dodecyl sulfate polyacrylamide gel electrophoresis. Neutrophilia was observed 24 h after both surgical procedures but did not differ (P ≥ 0.05) between the groups. In G1, the estimated concentration of ceruloplasmin increased (P ≤ 0.05) 48 h after the surgical procedure. The estimated ceruloplasmin concentration was significantly higher in G1 (P ≤ 0.05) when compared to G2 48 h postoperatively, and the estimated haptoglobin concentration was also significantly greater in G1 (P ≤ 0.05) than in G2 from 24 h to 7 days after surgery. Through the ceruloplasmin and haptoglobin estimated concentrations, we conclude that the minimally invasive ovariohysterectomy caused a more intense inflammatory response, which was not reflected in the white blood cell count.
