- Medication Assisted Treatment (MAT) is the treatment of addiction with medications, commonly used for opioid use disorders
- A long held belief is MAT simply replaces one addiction for another, which is patently false
- MAT is one of the most affective methods to treat a patient with opioid addiction
- Unfortunately, outdated requirements for prescribers along further prevent its widespread use

- Use the mnemonic NOT RECLUSE to rule out a brown recluse spider bite:
- Numerous bites (recluse spiders will bite once)
- Occurence (recluse bites between April- October)
- Timing (recluse spiders are… get this… reclusive)
- Red (recluse bites are white/pale)
- Elevated (recluse bites are flat)
- Chronic (recluse bites are acute)
- Large (recluse wounds are small)
- Ulceration, early (recluse bites ulcerate between 7-14 days)
- Swollen (recluse bites are flat)
- Exudative (recluse bites are dry)

- Blood concentrations over 0.4 mg/dL is associated with respiratory depression and possible death in alcohol naive patients
- Alcohol overdose accounts to 2,200 deaths per year
- Don’t forget about checking for hypoglycemia in severe alcohol intoxication
- Consider ketamine for agitation to prevent further respiratory depression
Editor’s note: check out our podcast on ketamine for alcohol withdrawal here

Here is a list of some very toxic natural substances:
#5: Tetrodotoxin: Found in pufferfish and other aquatic species
#4: Ricin: made from castor beans
#3: Mercury: natural element absorbable through skin and gloves
#2: Batrachotoxin: found on poison dart frogs
#1: Botulinum toxin: produced by Clostridium botulinum and causes a descending paralysis
Editor’s note: batrachotoxin is thought to be accumulated by the beatles and other insects dart frogs eat – those in captivity therefore are not poisonous
- Recent study has shown adjunctive ketamine can be useful in setting of alcohol withdrawal.
- Ketamine was associated with a decrease in the amount of benzodiazepines needed, likelihood of intubation, and a decrease in ICU length of stay by 3 days.
- For patients with benzodiazepine resistance, ketamine was shown to have symptom relief in an hour and decreased rate of benzodiazepine infusion.

- Tall flowering plant with phototoxic sap
- Direct skin contact with the sap can cause the skin to become photosensitive
- Severe blisters and even burns can result

- Snake bites commonly occur between April and October.
- Rattlesnake bites are the most common.
- Venom contains proteins/enzymes that cause local inflammation, coagulopathy, and systemic effects (hypotension, angioedema, renal failure, etc.) along with neurotoxins may cause fasciculations, ptosis, drooling, or hyporeflexia.
- Elevate and immobilize injured limb and treat pain.
- Check basic labs including coagulation studies, and update tetanus.
- Antidote is CroFab and use if patient has systemic symptoms. Anaphylaxis is a known complication of CroFab
- Avoid: ice, tourniquets, and incision and drainage.

- 1% of patients presenting to ED with alcohol intoxication end up going to the ICU.
- Most common critical illnesses were acute hypoxic respiratory failure, sepsis, and intracranial hemorrhage.
- Predictive markers: Vital abnormalities (hypoxia, tachycardic, tachypneic, hypothermic, hyperthermia, hypoglycemia) and patients receiving parenteral sedatives had higher incidence of ICU admission.

- A NEJM study report in July 2016 discussed a situation in New York during which 30 people became “zombie-like” after ingesting synthetic cannabinoids (aka “Spice).
- The ER managed to coordinate with the CDC to evaluate blood samples from 18 patients who were transported to the hospital.
- Of those who went to the ER, the mean age was 36.8, many of them were homeless, all of them were male. Mass spectrometry was used to confirm the presence of synthetic cannabinoid in their blood.
- Compared to normal THC, synthetic cannabinoids have a much lower EC50 and LD50.
- Spice intoxication presents in a variety of ways -patients may be hyperthermic, combative, delirious and/or seizing.
- Treatment is supportive, including fluids, cooling, electrolyte management, and sedatives.

- Cannabinoid Hyperemesis syndrome is a relatively new diagnosis that presents with vomiting and abdominal pain without a clear etiology in the setting of daily marijuana use.
- The pathophysiology is not well-understood well, but may involve cannabinoid receptors in the gut.
- Treatment is abstinence from marijuana, fluids, dextrose, and antiemetics (haldol, ondansetron, etc). Opioids should be avoided.
- Capsaicin cream on the abdomen may be helpful, as it can distract from the pain and vomiting. Milk can be used to reverse its effects.
