These injuries can be catastrophic. She sounds like she should be on IV antibiotics and monitored 24/7 by a vet. Don't you have an Emergency CLinic there? I am shocked that she had to sit all night like that.
Infections from these attacks are very, very common and difficult to treat. Not something that can be done at home normally.
We had one in our group that was kept at home and by the time we got her she ended up in intensive care for weeks...
I hope your vet can help her.
