A 9-year-old 2.9-kg (6.4-lb) sexually intact female Maltese was referred to the Veterinary Medical Teaching Hospital of Seoul National University for evaluation and treatment of mammary gland neoplasia. Masses were initially observed approximately 3 years previously and had slowly increased in size. The owner had also noticed an intermittent cough that began 1 year ago. On physical examination, the dog was bright, alert, and responsive, with pink mucous membranes and capillary refill time < 1 second. The dog's body condition score was 5 on a scale from 1 to 9. Rectal temperature was 39.3°C (102.7°F), heart rate was 120
A 7-month-old 1.3-kg (2.87-lb) sexually intact male Poodle was referred to the Veterinary Medical Teaching Hospital of Seoul National University for evaluation and treatment of microhepatica. The patient had a history of anorexia, weakness, and growth retardation and exhibited signs of hypoglycemic shock and blindness during examination by the referring veterinarian. Considering the patient's history and clinical signs, a portosystemic shunt was suspected, and CT was planned to confirm this diagnosis. On referral, results of a complete physical examination and thoracic radiography were unremarkable. A CBC and serum biochemical analysis indicated leukocytosis (20,310 cells/μL; reference range, 5,200 to 17,000
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.
5 dogs with a history of ventriculocordectomy were anesthetized with isoflurane for ovariohysterectomy, dental prophylaxis, or intracapsular lens extraction.
No remarkable, abnormal clinical signs such as exercise intolerance, respiratory distress, or stridor were found in 4 dogs. However, 1 dog had cough after drinking, which had started after the ventriculocordectomy. During intubation, laryngeal web, suspected to be a complication of ventriculocordectomy, was accidentally discovered.
TREATMENT AND OUTCOME
Laryngeal web was observed during intubation, necessitating the use of a smaller-diameter endotracheal tube (ETT) for intubation. However, the smaller cuff volume of the smaller ETT did not prevent the air leak. Therefore, the ETT with the inflated cuff was pulled cranially until the narrowed laryngeal lumen was plugged with the cuff behind the vocal cords. The ETT was secured to prevent slippage. No air leakage around the ETT cuff or complications related to the ETT placement were observed in the peri-anesthetic period in any dog.
Laryngeal web can be found in patients with a history of larynx-related surgeries and may allow only a small-diameter ETT to pass through. The sealing technique used for peri-cuff air leak using a small ETT described here that can pass through a laryngeal web could be useful to seal an air leak around the cuff without complications.
A 12-year-old 13.8-kg (30.4-lb) castrated male Beagle was examined at the Veterinary Medical Teaching Hospital of Seoul National University for a cervical mass and hoarseness. The owner had observed the mass 1 year previously, and there had been no notable change in size; however, barking sounds were slightly harsh recently. Cytologic examination of a fine-needle aspirate of the mass performed by the referring veterinarian suggested a diagnosis of thyroid carcinoma. On physical examination at our hospital, an approximately 3-cmdiameter, round, firm, immobile, apparently nonpainful mass was palpated subcutaneously in the region of the right thyroid gland. No other abnormalities
Objective—To evaluate the intraoperative and postoperative analgesic effects of intracameral lidocaine hydrochloride injection in dogs undergoing phacoemulsification.
Animals—12 healthy Beagles with healthy eyes.
Procedures—Dogs were randomly assigned to receive 1 of 2 intracameral injections: 2% lidocaine hydrochloride solution (0.3 mL) or an equivalent amount of balanced salt solution (BSS). All dogs were treated with acepromazine (0.05 mg/kg, IV) and cefazolin (30 mg/kg, IV), and tropicamide drops were topically applied to the eyes. Anesthesia was induced with propofol and maintained with isoflurane. The initial end-tidal isoflurane concentration was maintained at 1.2%. Heart rate, respiratory rate, arterial blood pressure, esophageal temperature, inspired and end-tidal isoflurane concentrations, and oxygen saturation were recorded every 5 minutes. The allocated agent was injected intracamerally after aspiration of the same volume of aqueous humor. Ten minutes after injection, phacoemulsification was performed. After surgery began, the isoflurane concentration was adjusted according to heart rate and mean arterial blood pressure. Pain scores were recorded before surgery and at 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 8, 16, and 24 hours after extubation.
Results—Isoflurane requirements were significantly higher in the BSS group than in the lidocaine group. Mean ± SD time to administration of supplementary analgesia was significantly shorter in the BSS group (1.4 ± 1.2 hours) than in the lidocaine group (4.9 ± 1.2 hours).
Conclusions and Clinical Relevance—Intracameral lidocaine injection had significant analgesic effects in dogs undergoing cataract surgery. Results of this study suggest the value of intracameral lidocaine injection as an analgesic for intraocular surgery in dogs.
