Danish to English Medical Medical (general)

I have a cardiac catheterisation report with a section containing the following details:
dato, kontr. CPR, læge, kont.spl., ass.spl., betj.
I am assuming that, apart from the date, these are referring to the people involved in the catheterisation (spl being nurse, I think) as each is followed by a set of initials. I might be wrong.
But I don't know some of them.
This query is for 'ass.spl'
(I am also posting queries for some of the others)
Any help with this query much appreciated. TIA
