Re: le sigh. up 160 to 600 in an hour after tiny dose increa
Please contact DCIN for help with costs. Ketones above trace levels are not easily managed at home nor would I recommend it. Venita had posted elsewhere that she may not be available today. This
link to the DCIN Facebook page gives e-mail addresses for others who are involved with DCIN (Diabetic Cats in Need) who can assist.
I'm going to preface this by saying I've not used R myself. I have watched it being used. I'll try to get some experienced R uses to chime in.
First and foremost, R is powerful. Let me restate this -- it's VERY powerful. It acts fast and is strong. You need to test often and you will need to do a curve with R. If you don't, you risk hypoglycemia in a way where it can be hard to intervene at home. If I'm scaring you, it's only to make sure you understand you are using an insulin that is very different that PZI (a basal insulin) and R needs to be used with the utmost respect. R is a bolus insulin -- it's meant to be used in conjunction with your basal insulin (PZI). A cat is typically started on a very small dose -- 0.1u, and then a curve is done with the R before making a dose change. It's action lasts about 4 hours. The dose is then systematically worked up.
I'm nervous that your vet started you at 0.5u of R. I'm even more nervous that you increased the R to 1.0u. Please test every hour (or more frequently) when using R.
Is Snowflake eating? Infection + not eating + not enough insulin is a recipe for ketones. You may need to be raising your PZI dose. From all of the high numbers earlier in the month, it looks like you are not giving enough PZI. Please discuss this with the folks on the PZI forum since I can't help you with your insulin dose. (I'm a Lantus user.) From your SS, you note there was blood in Snowflake's urine. Is there a UTI and is it being treated? Is the blood in your cat's urine from something other than an infection? There's nothing on your SS regarding an antibiotic.
If Snowflake isn't eating, please ask for help with assist feeding. Food is absolutely essential if you are trying to manage the ketones. You may even need to feed higher carb food if that's all that Snowflake will eat. You can manage the higher carbs with more insulin. Food is a priority or you will have even more problems to deal with.
Please contact DCIN. IMHO, you really can't manage this at home. The vets do more than just give R when treating ketones. You need to have blood levels for electrolytes run to make sure they are titrated properly. Potassium and phosphorus levels that are out of whack can kill your cat. Please get Snowflake checked out both for electrolyte levels and for an infection.
