 Bleeding upon removal of a nasotracheal or nasogastric tube can be quite alarming.

 The author's preference is to remove nasogastric tubes approximately 30 minutes before the end of anesthesia, as this will allow time for bleeding to stop prior to the horse being placed in recovery.

 If bleeding is anticipated, or happening while the horse is still tracheally intubated in recovery, the ET tube should be left in place until the bleeding has ceased or perhaps until the horse is standing.

 If the horse has been extubated, it may be necessary to pass a nasotracheal tube down the unaffected nostril to establish an airway.This can be difficult unless the horse is in a relatively deep plane of anesthesia.

 Some cases necessitate deepening anesthesia to facilitate re‐intubation of the trachea and to prevent the horse awakening until the hemorrhage has ceased.

 If the horse is laterally recumbent, the head must be tilted downward to prevent aspiration of blood.
