"appalling treatment"

I took my father to be admitted to ward 112 yesterday for knee surgery he is in his seventys and a diabetic with high blood pressure which is being controlled with medication .he was told pre admission not to take any medication or food prior to his operation .upon booking in he was ushered to a waiting room and told relatives were to go home I ignored the request for me to go home and waited with him . After three hours of him sitting in a chair I noticed him becoming unwell I went to the reception desk to inform them he was diabetic they said oh is he after forty five minutes someone eventually came to him .after another hour they took him to the ward this is now four hours since admission. On arrival on the ward they prepared him for surgery it was at this point five hours after admission they informed him his blood pressure was high and gave him his blood pressure medication and told us he would have to wait another hour for his pressure to come down .they then retested his blood pressure and it had significantly improved after another half hour a sister came in to inform him his surgery had been cancelled due to the fact theatre didn't want to take the risk of giving him epidural with high blood pressure and they had already changed there list and couldn't wait around forever for it to comedown .this is disgraceful and I wonder what would have happened if I had gone home .my dad was extremely upset and will refuse to have the surgery he so desperately needs to keep patients especially orthopaedic patients sitting in chairs five six hours is disgraceful.I myself had taken four days off work to be there for him he had gone twenty hours without food or medication had gone through extreme anxiety and was told upon leaving to take his tablets next time if I had not been there he would have been stuck at the hospital feeling unwell with no way of getting home
