Final answer:
Long-term catheters should generally be removed when a catheter-related bloodstream infection (CRBSI) occurs. However, in some cases where the infection is successfully treated, the catheter may be left in place with close monitoring.
Step-by-step explanation:
Long-term catheters are commonly used in medical settings for the delivery of medication or fluids. However, they can also be a source of bloodstream infections. The decision to remove a long-term catheter depends on various factors, including the presence of infection, the effectiveness of treatment, and the patient's overall condition.
If a patient develops a catheter-related bloodstream infection (CRBSI), it is generally recommended to remove the catheter as soon as possible. This is because the catheter itself can serve as a source of ongoing infection, and removing it can help prevent the spread of infection and facilitate the healing process.
In some cases, if the infection is successfully treated with antibiotics and the patient's condition improves, the catheter may be left in place. However, close monitoring is necessary to ensure that the infection does not recur or worsen.
