Hi all! Student nurse and total novice here. Need to know more about microbiology as I am very confused. If a patient has repeatedly been admitted and discharged with the same infection four times between now and beginning of January for Chest infection and they have responded to Meropen each time during admission but had readmission each discharge within 48 hours of being off Meropen what further testing could a lab do to get a more definitive idea of what bacteria is causing the issue? Pt is allergic to penicillin and has had 12 admissions for chest infections over the last 12 months. Hx of bilateral pneumonia, Ca tongue and throat, COPD, radiotherapy induced baroreflex. disorder.
Just need some more information on what microbiology tests could be helpful to narrow down what is causing this infection other than just telling us to treat with broad spectrum. Also if a patient has a lot of sputum and chest secretions which are difficult to clear due to restricted access (wired jaw) how do IV abx work to clear the bacteria in the sputum which is sitting in the chest and throat? I know jsystemically the bacteria will be eliminated. Y the immune response and abx but surely if there is bacteria in sputum sitting in the throat and lungs this is not treated systemically. Is there any kind of inhalable prophylactic treatment which could help to reduce the risk that any bacteria in the sputum is killed and this is not the cause of the reoccurring infection once off meropen.
