Abstract

Objective—To evaluate the prevalence of and risk factors for development of corneal ulcers after nonocular surgery performed with general anesthesia in dogs.

Design—Retrospective case-control study.

Animals—14 dogs with development of corneal ulcers after nonocular surgery and 718 control dogs.

Procedures—Medical records of dogs evaluated at the Veterinary Medical Teaching Hospital of Seoul National University from January 2009 to June 2011 were reviewed for assessment of risk factors for development of corneal ulcers.

Results—Among the 732 reviewed cases, 14 (1.9%) dogs of 6 breeds developed a corneal ulcer after nonocular surgery. Duration of anesthesia was significantly longer in dogs with ulcers than dogs without ulcers. The number of medications received and procedures performed were also significantly higher in dogs with ulcers than dogs without ulcers. Dogs with a small skull (OR, 8.59; 95% confidence interval [CI], 1.04 to 70.90) and dogs that received neurosurgery (OR, 21.12; 95% CI, 5.77 to 77.25) were more susceptible to development of corneal ulcers. Also, postoperative application of a fentanyl patch was a risk factor for development of corneal ulcers (OR, 4.53; 95% CI, 1.05 to 19.60).

Conclusions and Clinical Relevance—Several risk factors were identified for development of corneal ulcers after nonocular surgery was performed with general anesthesia in dogs. Perioperative eye protection strategies and postoperative ophthalmic examination are needed to reduce the occurrence of corneal ulcers and their progression, especially for high-risk dogs and procedures.

Abstract

Objective—To compare the feasibility of training veterinary medicine students to perform laparoscopic versus conventional open ovariectomy in live dogs.

Design—Randomized prospective parallel-group experiment.

Population—25 students completing the second year of their veterinary curriculum.

Procedures—Students were randomly assigned to 2 groups to receive 14 hours of specific training in either open ovariectomy (n = 13) or laparoscopic ovariectomy (12). Confidence, basic surgical skills, and basic laparoscopic skills were evaluated before and after training, prior to live surgical procedures.

Results—Scores related to basic surgical skills were high in both groups and did not improve with either training program. Before live animal surgeries, student confidence and basic laparoscopic skills improved after training in laparoscopic ovariectomy and were higher than after training in open ovariectomy. Surgery time was higher for the students who received training in laparoscopic ovariectomy (129 minutes; range, 84 to 143 minutes), compared with students who received training in open ovariectomy (80 minutes; range, 62 to 117 minutes). On a 55-point scoring system, ovariectomy scores were similar between students who received training in open ovariectomy (34.5; range, 16.5 to 45) and students who received training in laparoscopic ovariectomy (34.5; range, 25 to 44.5).

Conclusions and Clinical Relevance—The training programs were effective in improving student confidence and skills in laparoscopic ovariectomy. Results of this study suggested that veterinary medical students, with assistance from an instructor, may be taught to perform laparoscopic ovariectomies with performance equivalent to that for students performing open ovariectomies.
