Some brief guidelines on the proper use of lipid therapy:
1.5 ml/kg of 20% lipid emulsion IV over 2-3 min ( a litte bit slower than previous recs)
can repeat bolus in asystole and in those who initially improve but deteriorate later after being placed on infusion
0.25mg/kg/min infusion, can incraese if pt starts getting worse
should terminate after 1 hour unless pt still unstable
max dose not see in these guidelines but have seen it before: 8 mg/kg

We have started seeing these- patients with neutropenia, also patients with ulcerated lesions, especially to the face. Ask about cocaine use!
This is the cocaine tainted with levamisole, a veterinary dewormer. Up to 70% of the cocaine seized by the DEA contains levamisole.
NEJM has cool and impressive case of vasculitis on its images in Medicine section.
Call the PCC!!!

The best article showing the prognostic significance of hyperkalemia.
My nuggets from it:
1. hyperkalemia >5.5 meant certain death unless you treat with antidote
2. treatment of hyperkalemia with methods that alkalinize the serum, force K movement into the cell, or force the elimination of K don't make sense in these cases. Hyperkalemia here is just a measure of Na/K ATPase poisoning by digitalis glycosides.
3. Hyperkalemia was better prognostic marker for mortality than either ECG and digoxin level.
