Which of the following statements regarding equine nasogastric intubation and medication is FALSE?
A. The nasogastric tube should be guided into the dorsal meatus of the horse’s nasal passages. B. When placed properly, the tube can be seen on the left side of the horse’s neck as it passes through the esophagus and into the stomach. C. Force should NEVER be used at any time during nasogastric intubation. D. A horse could potentially die from gastric rupture when its stomach is overfilled with large volumes of medication or fluid delivered through a nasogastric tube
The nasogastric tube should be guided into the dorsal meatus of the horse’s nasal passages.-a: a nasogastric tube placed properly into the ventral meatus will feed easily into the esophagus and meet little resistance along the way, providing there are no obstructions such as tumors or foreign objects.
excessive force during nasogastric intubation can damage the ethmoturbinates of the equine nasal passages, which will result in an exorbitant amount of bleeding. force can also rupture the esophagus if there is a foreign body present.
an equine stomach should always be checked for gastric reflux before introducing any water or medication. if an abnormally large amount of ingesta is present in the stomach (this is usually indicated when ingesta flows freely out of the nasogastric tube), then the delivery of medication or water should be postponed until the stomach empties. this will reduce the risk of gastric overfilling and potential rupture.
