[Star Wars] Are you in danger of infection/death if you lose a limb to a lightsaber?

Like, say, for example if Luke was rescued at the end of Empire Strikes Back but wasn't able to immediately go to a clinic, would he still be alright? And if he wouldn't, what would need to be done so that he was?

Asking for a fanfiction idea of mine.

Yes, you are in serious danger of infection without any medical attention.

Burns are notorious for being major gateways for infections, as there are no defenses left to stop something from directly entering your body through the wound. The single biggest threat to someone that has experienced serious burns is infection, and many people die as a result of it. 

To ensure that an infection has the lowest chance of being contracted the wound would have to be thoroughly cleaned and properly dressed. The dressing would have to be regularly changed, and dead flesh would have to be removed. It is entirely possible that there are other, more advanced medical procedures to deal with severe burns, though.
