Tratamento profilático com autohemoterapia em gatas submetidas à ovariohisterectomia eletiva.

Abstract

In order to evaluate the effectiveness of autohemotherapy administered prophylactically in cats undergoing ovariohysterectomy, 12 mongrel cats were used, clinically healthy, aged 14.5 ± 6.1 months and weight of 2.4 ± 0.3 kg. Compounds were two experimental groups: Group autohemotherapy where there were two administrations of autologous blood intramuscularly, a three day before surgery and another 60 minutes before surgery; and a control group where enrofloxacin was administered 60 minutes before surgery. In the anesthetic protocol xylazine was used as premedication and ketamine for induction of anesthesia, associated with epidural anesthesia with 2% lidocaine and morphine. Heart rate, respiratory rate and body temperature were evaluated once a day, starting three days before surgery until the 10th postoperative day, as well as general data such as body weight and duration of surgery. Haematological evaluation was performed three days before and the day of surgery, and 1, 2, 3 and 7 days postoperatively. Surgical wounds were evaluated every other day until the 10th postoperative day. The surgical procedure lasted on average 50.7 ± 4.0 minutes in autohemotherapy group and 49.8 ± 6.2 minutes in the control group. The results of body weight and physiological parameters (heart rate, respiratory rate and body temperature) did not vary statistically. Blood biochemistry did not vary significantly, however, the blood count, red blood cells values, hemoglobin, hematocrit and total leukocytes significantly increased in the control group compared to autohemotherapy group. In both groups mild inflammatory processes was induced early, with no clinical infection, and good healing outcome. It was concluded that the autohemotherapy administered prophylactically was as effective as the antibiotic prophylaxis in preventing cats post-operative infection ovariohysterectomy undergoing elective surgery.
