title: Complications of nasogastric intubation in horses: nine cases (1987-1989).
abstract: Pharyngeal or esophageal trauma was diagnosed in 9 horses after nasogastric intubation. Evidence of trauma (edema or ulceration) was detected in the pharynx of 3 horses and in the esophagus of 6 horses. Complications associated with nasogastric intubation were first observed in 5 horses while they were intubated and in 4 horses after extubation. Clinical signs of pharyngeal or esophageal trauma were similar, and included salivation, bruxism, coughing, and nasal discharge. Treatment, including extubation, enteral feeding through a small nasogastric tube, or esophagostomy distal to the affected site, was attempted in 6 horses. Three of 6 treated horses survived, but 4 of 5 horses with perforated esophagus were euthanatized.
