Can MRSA Lead To Other Complications Which Are Fatal?

Hello, my name is Mary, Four years ago my fiance had a hernia repair, in and out the same day. The following day he was taken by ambulance back to hospital with MRSA He was put on antibiotic drip, with a compress on the wound, and putb on the ear nose and throat ward.On about the fourth day of visiting he was dilerious etc. I checked his infection, someone had put a marker round it , the infection was now round his back. I alerted a nurse Richard was not well to get someone to check him. Within 5mins 4 people appeared, they operated on the bed and repacked the wound. He lost over a stone in weight, and had stomach problems for the rest of his life. He felt ill went to see his doctor in Shirley on the 30th May, he was given paracetamol and a throat spray and told he had a kidney virus, he was found dead on his own on the 10th of June this year.Is it possible the MRSA contributed to his death. The inquest result was unaccertainable natural causes, enlarged speen was mentioned but not on the outcome????????thanks. YYYY@YYYY
