Lecture 36 - febrile neutropenia Flashcards
Acute myeloid leukaemia symptoms/signs
- tiredness
- sever brusing
- unusual bleeding from gums
- low haemoblobin
- lowplatelets
- low nuetrophils
What do we do next
- Take a bone marrow examination and look at cells
- can see that there is not normal bone marrow
-had chemotherapy to kill the unusual white blood cells, however also damages lots of other rapidly dividing cells
Febrile neutropenia
- Started shivering again, and had a high fever
- WBC was very low
- platelet count wa svery low
-nothing in history suggests site of infection
- however after chemotherpay, this destorys neutrophils and these are needed to fight infection
- can get infection easily when low neutrophols
- dont often show sign where infection is as nuetrophils usualy reuslt in inflamation of an area
- this person had high rate of bacteraemia
- these infections tend to come from endogenous gut and skin flora
- very high mortality in patient with gram negative bacteraemia
-can give antibiotic treatment
What is most common cause of death of AML?
what is the most common cause of infection?
infection
=pseudomonas aeruginosa
Relationship between amount of white blood cells, and risk of infection
If neutrophils are below 0.1 then very veyr high risk of infection, if tehy are around 5 then not too bad infections
-and if this lasts for a long time, then will get far worse
Most common infections-
- lung infections
- mouth infections
- central catheter line infections
- blood infections
What antibiotics are usually used?
tazocin - piperacillin adn tazobactam
-both affect almost all aerboic bacteria nad also
gentamicin
-this is for the gram negative bacteria
