præ G

Danish to English Medical Medical (general)

The following appears in the A/E notes of an elderly patient with exacerbation of COPD who's being admitted:
Skal indlægges præ G.

This is the last line under plan.
There's
Drugs
Fluids
Catheter
Bloods and finally
Skal indlægges præ G.


Does anyone know what the "G" here might be referring to please?
