In a few isolated cases of pure opioid toxicity, patients may fail to respond to aggressive airway control and high-dose naloxone. In the absence of other etiology, prolonged hypoxia may cause a terminal state unresponsive to naloxone. Buprenorphine (Buprenex) toxicity has been reported to respond only partially to naloxone.

Cardiac arrest in the setting of pure opioid toxicity is almost certainly an indication of severe hypoxia and poor neurologic outcome.
