Hospitals/Doctors and Mistakes (Long)

Regarding previous post on Doctors and Guns. I personnally went through this on 6/1/01 when I had a Heart Caterazation performed on me. Not having the procedure done before I really only knew what to expect from the pamplets given and a video shown at the Hospital. Needless to say I expierenced more pain then I was suppose to, as the Doctor was completing the procedure he encountered a spot that he could not determine what it was. One of the nurses finall came up with the idea to check the Hypos used during the procedure. They found that instaed of Lidocaine used to deaden the area I was injected with something else. I was awake during the procedure and asked the Doctor what had happened and would get back to me. I talked to him the fo;;owing Monday and he said that the setup team had placed the wrong materials on the table and that a check with the radiologist and others said that the material was harmless. Today I called the hospital and talked to the person responsible for the Heart Cath section what had been done to correct problem. He stated an incident report had been made and a new verification procedure established. However I told him that while this may good now what would have happened to me if something potential dangerous had been used and I really did not appreciate going through a procedure without the pain relief that I was suppose to have he said someone would get back with me next week. THINK I SHOULD ASK FOR A KRIEGOFF?
