The present study aims to verify whether dogs and cats submitted to dissociative anesthesia for elective orchiectomy may present alterations in the tear production and consequent lesions on the ocular surface. For this purpose, 40 animals, 22 cats and 18 dogs, underwent an ophthalmic semiotechnique composed of the evaluation of anterior and posterior chambers, fundscopy, Schirmer's tear test (TLS) and fluorescein test. Subsequently, they underwent dissociative anesthesia, associating ketamine with diazepam or midazolam. Immediately at the end of the procedure, the fluorescein and TLS test was repeated. After 24 hours, a new ophthalmic evaluation was performed to compare the results obtained. There were no ophthalmic changes. With the use of diazepam, TLS remained within the normal range with a median of 19 mm / min, with a mean and standard deviation of 19.27 ± 3.01 mm / min for dogs and a median of 18 mm / min, with a mean and standard deviation of 19.05 ± 2.81 mm / min for cats. When using midazolam, the TLS of the dogs had a median of 19 mm / min, with a mean and standard deviation of 18.84 ± 2.69 mm / min and of the cats, they had a median of 18 mm / min with a mean and standard deviation of 18.37 ± 2.32 mm / min. The results found suggest that the use of dissociative anesthesia for short procedures does not significantly alter the tear production, nor does it cause eye injuries.

The occurrence of incisional hernias in pigs is poorly described, so the objective of the study is to report a case of incisional hernia in pig treated with polypropylene mesh. A 1 year old male, mixed breed pig weighing 22 kg was treated at the HVU-UFOB. During the anamnesis, the owner reported that the animal had swelling in the abdominal region, having a suggestive diagnosis of umbilical hernia, confirmed by ultrasound. In view of the findings, it was decided to perform herniorrhaphy with direct suture. Ten days after surgery, adequate healing of the surgical wound was verified with the absence of a hernial ring. Fifty-one after surgery, the animal returned with an increase in abdominal volume at the surgery site. On physical examination, the presence of a 12 cm ring and reducible intestinal loops in the hernial sac were identified. After a new ultrasound examination, the diagnosis of incisional hernia was defined. A new herniorrhaphy with polypropylene mesh was chosen. After 10 days, the wound healing was verified. Incisional hernias in pigs are generally related to the animal's age, sex, breed and species, as well as flaws in the surgical technique. Biological or synthetic materials are used for the correction, in order to reinforce safety in the incision line. One year after herniorrhaphy, there was no recurrence, which shows a satisfactory result with the use of the polypropylene mesh.
