Q

When giving Benzos and Barbituates to pts with intoxication problems what are some considerations?

A

The more lipophillic and short duration of action –> the more ADDICTING the drug

Can also cause withdrawal from the drugs

(BENZOS also can cause Alzhemiers and Dementia with long term use)

22
Q

If needing to do a rapid taper for Intoxication disorders what are some better options than Benzos and Barbiturates?

A

Carbamezapine/Valproic Acid –> good for rapid taper

Gabapentin and Tizanidine (highly effective)

23
Q

What are some Opiate use disorder treatment options?

A

CD treatment –> support, education, etc

Meds –> Methadone, Naltrexone, Buprenorphine

24
Q

Methadone (an Opioid substitute) cannot be use with what?

A

Benzos and other CYP3A4 substrates

25
Q

Cocaine abuse can lead to what from a hypermetabolic state?

A

Rhabdomyolysis with Compartment Syndrome

26
Q

What are your treatment options for Stimulant Use Disorder?

A

No Medications

Narcotics Anonymous

27
Q

What are some treatment options for Tobacco Use Disorder?

A

CBT

Agonist Substitution therapy (Nicotine Gum/Transdermal Patch)

Buproprion or Varenicline

40
Q

A
  • Clinical Institute Withdrawal Assessment for Alcohol
  • Assigns numerical values to orientation, N/V, tremor, sweating, anxiety, agitation, tactile/auditory/visual disturbances and HA

  • Dangers ↑ when used with another 3A4 substrate!***
44
Q

If a methadone maintenance patient is encountered in the ED and needs pain management what is the proper protocol?

A
  • Provider calls on-call service at methadone clinic and verifies dosage
  • The correct methadone dosage is continued while patient is hospitalized
