Do the following things, in this order of priority.
A simple acronym solves everything. The point is not to let the patient DIE.
Lipase is more specific for pancreatic disorders than amylase.
Lipase has a p in it. So does pancreas.
Amylase has nothing.
It’s magic!
There are three major ones, plus more!
The way to remember this is that, in line with the subpar nature of hypokalaemia, everything is weak and low!
ST depression is a depression, so it is low.
The T waves have low amplitude, so they too are low.
The dip of the letter U, as in U waves, looks like the minimum point of a parabola, so it’s also low.
Conveniently, it all follows an alphabetical pattern: ST, T, U.
“Cushing response?!” you cry. “Why is Cushing’s name everywhere and why should I care?! BAH!”
How astute! In fact, that disgruntled sound you make is quite appropriate.
If hyperkalaemia is indeed real and not caused by haemolysis or a bad sample, treatment can be appropriate. It’s urgent if there are ECG changes.
Of course, the underlying cause should be treated; if it’s hypoaldosteronism, such as from adrenal insufficiency, corticosteroids should be given. If it’s volume depletion, that should be corrected. If the hyperkalaemia is caused by a medication, that medication should be ceased.
A lumbar puncture is a procedure that involving drawing out cerebrospinal fluid, fondly known as CSF. For example, it can be used to check CSF for immune cells and glucose levels in suspected meningitis.
Lumbar puncture is considered an invasive procedure. But even with that aside, it’s not appropriate for everyone. That is, it does not suit all patients.
Contraindications to lumbar puncture are:
Colles and Smith fractures are both fractures of the distal radius.
And that’s how an American CD is made.
