What is the first step in treating an anaphylactic reaction during dialysis?

The first step in treating an anaphylactic reaction during dialysis is to stop the medication causing the reaction. This is crucial because the immediate cessation of the offending agent prevents further exacerbation of the reaction. Anaphylaxis can lead to severe symptoms such as difficulty breathing, swelling, and even cardiovascular collapse, so quickly stopping the trigger helps stabilize the patient.

While administering oxygen, notifying the medical doctor, and starting an IV may be critical later in the treatment process, they are secondary steps that follow the initial action of stopping the medication. The priority is to halt exposure to whatever substance is causing the severe allergic response, as continuing to administer it can worsen the patient's condition significantly. This is a standard protocol in managing anaphylactic reactions to ensure the patient's safety and initiate appropriate interventions without delay.
