Does anyone know anything that will help my kitten ?

She is just 4 months old and was recently deed and had her final vacinations. She was off colour and vomiting for a week after the operation and i was in constant contact with the vet over her condition, towards the end of the week she only ate very little amounts. on Saturday she was operated on and it was discovered she had not one but two telescopic bowel obstructions. She has spent just over 48 hours on IV and been cared for by the vet, the only time she ate after the op was when given drugs to stimulate the appetite and threw up after. the vet is leaning towards euthanasia for her as her wound is still weeping and she will not eat and therefore not able to p. We cannot say for sure that she has a blockage and may just take a few days and encouragement to get better, the vet advised that she is not in pain but soon enough a desicion needs to be made. Does anyone have any idea about a condition like this or knowledge of what we can do or try ?
