What are your orders or facility policy on Cisplatin Pre & Post Hydration, including Potassium and Magnesium? Do some do just Potassium, or are they always Potassium and Magnesium?
For low doses, some order sets say 250-500 mL pre, 250-500 mL with Cisplatin added, and 250-500 mL. Most do 500 mL pre, 500 mL with Cisplatin, and 500mL post for a total of 1500 mL which seems pretty reasonable. Example Cisplatin dose: 23mg Q1W
For higher doses, order sets say 1000 mL pre, 500 with Cisplatin added, and 1000 mL post. Total volume 2500 mL. Example Cisplatin dose: 93mg Q3W
The 2500 mL just seems like a lot of fluid to me in one sitting. The patient is also there ALL DAY. We typically also hydrate these patients at least one other time a week with a liter bag. I've seen some nurses run pos hydration concurrently with Cisplatin and am curious if others do the same? I'm not a new nurse, not even new to Oncology, but new to infusion/chemo/immuno. I've discussed with co-workers and we're pretty much divided, most newer/inexperienced nurses think it's too high while the more experienced nurses think it is fine. I trust my nurse managers and fellow co-workers, but maybe someone can give me an explanation in different terms where it will "click" for me?
Thank you for input.
