 The importance of preventing airway obstruction cannot be over emphasized.

 Obstruction in the recovery phase will lead to extreme anxiety in the awakening horse such that it may be impossible to control the horse to establish an airway.

 In extreme cases, airway obstruction may result in negative pressure pulmonary edema (NPPE) which can be fatal (see Chapter 38).

 Thus, it is important to have a plan to protect the airway, and to check for airway patency following ET tube removal.

 Because airway obstruction is most likely to result from nasal edema, administration of phenylephrine intranasally or placement of a nasal tube will greatly reduce the incidence of airway obstruction (see Figure 4.10).Airway obstruction, due to nasal edema is more likely to occur when the horse has been in dorsal recumbency for long periods.
