What should be done when interrupting a hemodialysis treatment for a patient's bathroom break?

When a patient needs to take a bathroom break during hemodialysis, it is crucial to manage the patient's blood safely and maintain the integrity of the dialysis process. Therefore, returning the patient's blood and recirculating the extracorporeal circuit with normal saline is the appropriate action. This process helps ensure that the blood remains within a safe environment and minimizes the risk of clotting or other complications that could arise from leaving the blood static in the circuit.

By returning the patient’s blood, you are effectively maintaining the flow of blood and ensuring that it does not coagulate while the patient is away from the machine. Recirculating with normal saline is also essential as it helps to keep the circuit patency, thus facilitating a smooth resumption of dialysis once the patient returns.

This approach not only prioritizes the patient’s needs but also aligns with best practices in hemodialysis management. It ensures that treatment can be seamlessly continued after a short interruption without causing harm or delays in therapy.
