The most crucial part of protective isolation is hand hygiene. Our nurses and doctors always wash their hands with antibacterial soap (in the dispensers that are usually outside the rooms) or with an alcoholic rub before they enter your room. Your visitors will be advised to do the same. When your white blood count is low, you may need to take antibiotics to protect you from infections caused by bacteria that occur naturally in your body. This is called prophylactic antibiotic therapy.
In a healthy person, these bacteria are harmless, but with a weakened immune system, they can cause infections. You will also need antiviral treatment to help prevent viral infections. These antibiotics and antivirals are a vital part of your treatment. Despite prophylactic or preventative medication, it is likely that at some point during your transplant, you will develop an infection. Infections are a common side effect of stem cell transplants. Your low white cell count and poorly functioning immune system mean you have a high risk of infection.
Fever is the most common sign of infection. Your temperature is checked regularly, along with your pulse and blood pressure, particularly while your white cell count remains low. Some people can feel cold and shiver (a rigor) before the fever appears. If you experience this, you should let your nurse know straight away. Sometimes, an infection can cause your blood pressure to drop. If this happens, you will be given extra fluid; on occasion, you may even need medication to help bring your blood pressure back up.
The medicines that are used to treat infections include antibiotics, antifungals and antivirals. Some of these drugs can cause issues with your liver or kidneys. For this reason, these organs will be monitored very closely, and your treatment can be adjusted if necessary. When you have a fever, the doctor will examine you and will usually give intravenous antibiotics. These are antibiotics that are given to you through your central venous catheter. The doctor may also order a chest X-ray and take a blood sample.
You may also be given a dose of paracetamol, which brings your temperature down and helps you to feel a little better while waiting for the antibiotics to work. Some other samples may also be taken to find out the cause of your infection, such as urine, stool or swabs. It is not unusual for the laboratory to receive a negative result from the cultures, despite you looking and feeling as though you have an infection. Therefore, a broad range of antibiotics is used to treat you for an infection.
These antibiotics can work against many types of organisms and bacteria. You will receive antibiotics until the cause of your infection is identified, or your temperature returns to normal. If you still have a temperature after 24 to 48 hours, the tests may be repeated, and the antibiotics may be changed. Once your fever and symptoms of infection have settled, the antibiotic treatment will be stopped. It is common for people to have several fevers and cycles of antibiotics during their transplant.
