The purpose of the study reported here, to investigate the effect of atropine on cardio-respiratory parameters and body temperature in cats undergoing ovariohysterectomy with the combination of medetomidine-ketamine anesthesia. Twenty-six adult female intact domestic cats were admitted to Ankara University Faculty of Veterinary Medicine, Department of Obstetrics and Gynecology for routine elective ovariohysterectomy. The animals were divided into two groups by the randomized grouping method before the operation. Trial animals (n=14) received atropine together with medetomidine and ketamine anesthesia. In control animals (n=12) received the same anesthesia without atropine injection. At the end of the operation, animals were moved to the critical care unit and the measurements of vital parameters were performed. Heart, respiration rates, deep rectal temperature and status of anesthesia recovery were recorded after the operation every 10 minutes for 1 hour.There was a group, time, and group x time interaction noted for heart rate. Treatment cats showed greater heart rate during measurement. The mean respiratory rate and deep rectal temperature were in reference ranges for cats and similar for both groups. In both groups significant sedation induced, however, the scores were not statistically significant among groups.In conclusion, atropine is an effective drug preventing decrease of heart rate and patients have shown less undesirable side effects when it is used before the administration of medetomidine in cats that operated for ovariohysterectomy.

The case was a 2.5-year-old calico cat with an abdominal mass, which was brought from a private clinic to Ankara University, Veterinary Faculty, Animal Hospital, Internal Diseases Clinic. It was reported that the cat was operated 20 days ago, a mass of 8 cm in diameter near the jejunum was removed, but a second mass in the region was noticed in the investigation. The mass removed with operation was found to be Lymphoblastic lymphocarcinoma. In the ultrasonography, a two lobed mass of 3x4.5 cm in size was detected in the mesenterium near the liver. An alternative treatment was considered to be performed instead of reoperation on determining that the mass recurred in a very short time and was malignant as a result of the pathology. Considering that the cat was young and with good general condition, it was decided to administer chemotherapy. Modified Wisconsin Maddison method was selected for the chemotherapy. Shortly after the initiation of the chemotherapy protocol, chemotherapy had to be discontinued due to dense acid accumulation in the abdomen and deterioration of the general condition. Feline Corona Virus was detected positive in the cat scanned for subclinical diseases.
