My kittens has feline Panlekopenia?

I had 4 cats one mother and 3 kittens. mother and one kitten died with this diseases within one day of showing symptoms. we couldn't find it out as blood tests aren't available in my city. Now i only have 2 kittens left their treatment is going on. On daily basis they are having 100 ml saline IV. . The injections that are used are (risek 40mg, oxidil 250 mg, onset 4mg, neurobion) . Its been two days of the treatment doctor says it will be a 3 days treatment. I have put them in blanket in warm room. Can anyone please tell me some tips or medicine they think can work like miracle. I already lost 2 i can't afford losing them too. I m devastated.
Information: they weren't vaccinated. I was going to get them vaccinated but they got thia disease and are expiring real fast.
