Document Summary
Why do we use these drugs? (therapeutic uses: alcohol withdrawal, anxiety/insomnia, seizure management, reduce muscle spasm, ppl with agitation, sedation (general anesthesia)/hypnosis. *still active even after metabolized=drug effects apparent long after drug has been metabolized (=long half-life); also means increased liver toxicity. When administering them, what would you want to monitor: monitor: rr, shouldn"t be below 12 breaths per min; bp, loc and alertness (monitor heart rhythms if given to cardiac pt) Beware of administering iv, don"t give with other cns depressants, avoid in cardiac pts and those with breathing probs or pt"s already on htn meds. Flumazenil (romazicon)-short half-life (1hr)=repeated dosing, antagonist, reverses sedative effects *may not reduce sedative effect; *drug should be tapered off, withdrawal will look like anxiety attack (delirium, htn, muscle spasm, paranoia, convulsions) Therapeutic uses: seizure management-at non-sedative doses, (general) anesthesia induction-sedation, treatment of insomnia-not so much anymore, replaced by benzos, head injury-reduction of the brains need for oxygen and glucose.
