Do you need to soak calcium alginate rope for packing

No - one of the main purposes of calcium alginate is to help absorb drainage so that the wound can heal You are right to not soak it If you go to changethe dressing and the calcium alginate is still dry at that time you should do one of two things Leave it in longer- change the frequency to every other day or every 3 days Or get the wound care changed to something else If it is a dry
