A 6-year-old castrated male Llewelyn Setter that weighed 32.4 kg (71.3 lb) was examined at the Veterinary Teaching Hospital at Colorado State University because of an acute onset of signs of pain with a nonspecific origin and respiratory distress

Introduction Tracheal collapse (TC) is a common cause of respiratory difficulty and cough in older small and toy-breed dogs. 1 , 2 Endoscopy is considered the gold standard for diagnosis of TC, detecting concurrent diseases, and identifying

Objective

To characterize respiratory function and treatment in dogs with findings compatible with those of human adult respiratory distress syndrome (ARDS) and to evaluate the application in dogs of clinical criteria for diagnosis of ARDS.

Design

Retrospective review of medical records.

Animals

19 dogs with acute respiratory distress syndrome.

Results

Arterial blood pH was 7.30 ± 0.059 (mean ± SD). Nine dogs had metabolic acidosis. In nonmechanically ventilated dogs, Paco2 was 15.0 to 54.9 mm of Hg. Respiratory acidosis developed in 2 mechanically ventilated dogs. Hypoxemia was observed in 4 of 5 dogs breathing room air. In 4 mechanically ventilated dogs, oxygenation was inadequate, despite use of > 60% inspired O2 and positive end-expiratory pressure in 3 dogs. Alveolar-to-arterial oxygen tension gradients were widened in 4 dogs breathing room air and in 6 dogs ventilated with 100% O2.

Ten dogs were mechanically ventilated; ventilatory rate was 18 to 60 breaths/min. Tidal volume was 12 ± 3.8 ml/kg of body weight in 4 dogs, minute ventilation > 400 ml/kg/min in 2 dogs, and peak airway pressures > 25 cm of H2O in 6 dogs. Positive end-expiratory pressure was used in 8 dogs. Pneumothorax was detected in 5 ventilated dogs.

Human clinical criteria for diagnosis of ARDS were fulfilled in 7 dogs. Fluid treatment consisted of IV crystalloids and synthetic colloids. Drugs most often administered were antibiotics and loop diuretics.

Clinical Implications

Human clinical criteria for identification of ARDS may be helpful in diagnosis of acute respiratory distress syndrome in dogs. (J Am Vet Med Assoc 1996;208:1428-1433)
