If you had a 74 year old woman come into your ER who has a history of heart disease, who a week earlier had a cardiac catherization performed, and was now complaining of pain at the site of the cathater entry, and had a fever of 101.1 dg F. Would it be S.O.P. to have a blood culture performed? Im asking because this is the situation of my Mother. Last weds. she went into the ER as stated above, they performed no blood work, than on friday (less than 48 hours later), she went to the ER again very ill...She was diagnosed with bacteremia, sepsis, a UTI, and a possible vegetative spot on her heart, and she has lost all mental faculties.
