Reversal agents are rescue drugs, not discharge drugs

Two scenarios recur in sedation adverse events, and neither is exotic. One is a reversal agent used to get a patient out the door. The other is the wrong reversal agent altogether. Both are pharmacology problems that were decided before the patient arrived, and both are avoidable with a half-life table and a drill.

In short

A reversal agent is a rescue drug, never a discharge drug. Flumazenil's duration is far shorter than a long-acting benzodiazepine's, especially in older patients, so reversal restarts the observation window rather than ending it. Flumazenil does nothing for an opioid; naloxone does, and it too is short-acting. Opioids depress respiratory drive; benzodiazepines relax airway muscle. They are different emergencies with different first moves, and the combination stacks both.
