Follow-up

Further Inpatient Care

  • Assess for suicide risk.
  • With barbiturate toxicity, patients may be discharged after 6 hours of observation, provided that they are asymptomatic or minimally symptomatic.
  • Observe patients with benzodiazepine toxicity for at least 2 hours after recovery from flumazenil for late respiratory depression or resedation.
  • Patients with glutethimide (Doriden) toxicity require 24 hours of observation in the hospital.

Complications

  • Some sedative-hypnotics may have teratogenic or mutagenic effects.

Patient Education

Miscellaneous

Medicolegal Pitfalls

  • The use of flumazenil can be dangerous because of the potential to elicit withdrawal agitation or seizure. Its role in acute overdose is marginal because benzodiazepine overdose resulting in airway compromise can be adequately treated in an emergency setting without the dangers of flumazenil use. Recall that flumazenil's effect is likely to be shorter than that of many of the benzodiazepines.
  • Identification of the sedative or sedatives involved is important because some drug-specific treatments are available. Do not assume that addressing the ABCs is sufficient in a sedative overdose.
  • However, managing the ABCs is paramount. In particular, the airway should be protected if giving activated charcoal to a patient with declining mental status or obtundation. 
  • Be sure to consider co-ingestions. Sedatives are often abused in order to offset the effects of other drugs of abuse.
