When tapping a pleural effusion
Proceed with due care (in profusion)
Trephining the heart is not very smart
And may compromise general perfusion

Aspiring to Plastics SR?
Then carefully think where you are
A hasty decision on site of incision
Can leave a much uglier scar

If faced with a ruptured aorta
Don't wait for a hospital porter
Get in there with speed, don't let the man bleed
Or his life will be quite a lot shorter

When seeing a patient in shock
Don't loiter or look at the clock
But get the chap luered and filled up with fluid
Or you could end up in the dock
