Creatine levels and minor surgery to remove lipoma
Question:
(thanks for the info) I understand that they gave the cat a seditive in order to take the blood for the test. When we brought him home (after he had been at the vet’s for most of the day) he was really spaced-out, and his eyes were wide open (dilated). He got better (less spaced-out) but even this morning his eyes are still not normal (not contracting even in the light) but they’re a little bit better then yesterday. He’s also very quiet, even timid, or introverted. What woul they give him that would cause such a long lasting effect? Is there a risk of permenent dammage?
Response:
My cats have never been sedated when they had blood drawn. I really can’t answer this as it seems odd to me. Also, our vet uses Isoflurane anesthetic which is much safer than the older anesthetics which took days to flush out of the system. Our cats are awake and active within a few hours after the anethesia. Have you considered maybe getting a second opinion with another vet? > (thanks for the info) > I understand that they gave the cat a seditive in order to take the blood for > the test.

Tally, the most commonly used general anesthetic agent is Ketamine. This drug is metabolized in the *liver*, not the kidneys, principally by demethylation and hydroxylation and these metabolites along with unchanged ketamine are eliminated in the urine.

Joe, Are you referring to "creatine" or "creatinine". They’re not the same and often confused. The reference range you’ve stated approximates creatinine ranges. Creatine is synthesized from arginine, glycine and methionine (amino acids) and readily combines with phosphate. Creatinine is a nitrogenous compound formed as the end product of creatine metabolism – its formed largely in muscle and its production is not significantly affected by dietary protein or blood in the gastrointestinal tract. Its a more accurate indicator of renal function than BUN.. If your concerned about possible anesthetic risks, due to possible renal or hepatic disorders, I highly recommend Isoflurane (inhalant) as the anesthetic agent of choice. Some of Iso’s distinct advantages over other anesthetic agents are lessened myocardial depressant and catecholamine sensitizing effects – cardiodepression generally is minimal at doses causing surgical planes of anesthesia, the ability to be used *safely* in cats with either hepatic or renal disease, and most importantly, its effects can be instantly reversed by just "turning it off"! The vast majority of the drug is eliminated via the lungs – not the kidneys. Only about 0.17% (not 17%) is matabolized in the liver. I can say, with reasonable certainty, Isoflurane is the *safest* anesthetic agent there is! Iso is the *only* anesthetic agent I allow to be used on my cats. I highly recommend it. btw, its more expensive – but well, well worth it. Best of luck. Phil.

Response:
Our 7 year old male cat (weighs 18 to 20 pounds) had dental surgery 5 or 6 months ago to remove some mid and back teeth because of gum problems (we were told this is a genetic problem that affects some cats). At the time the vet (now retired) did not do a blood test, which I am told is a common thing to do before you perform a procedure that involves anesthesia. So we don’t know his creatine level at that time. Today we took the cat in to have a lipoma removed from his back leg. It was previously established that it was not detrimental to the cat’s health, but we wanted it removed because it feels really icky and it might be getting larger. Anyways, they do a blood test and tell us that his creatine level is 280, and that the normal range is 70 to 220, and that we should come in again in 6 to 8 weeks and have it checked again. The cat did not eat anything during the 14 (or more) hours before the test. As a result of this high creatine level, the vet did not perform the lipoma removal. In talking to another vet, I am told the normal creatine range is 50 to 177. So now I ask - what is an acceptible creatine value for a 7 year old male cat that weighs 18 to 20 pounds and is active and not showing any signs of poor health? Is a high creatine level grounds to postpone minor surgery? What can happen in 6 to 8 weeks that would result in a change in creatine levels? Is there something we should do NOW to reduce this creatine level?
Response:
Normal ranges vary depending on the labs that perform the testing, so the norms should be compared on the results obtained from the lab. You have a legal right to the lab results if you ask your vet. Creatinin is one indicator of kidney function, and it would be appropriate for you vet to re-test before surgery. Anesthesia is metabolized through the kidneys, so it’s important for him to understand what’s going on before he administers any during surgery. I don’t think there is anything you should do to attempt to lower the levels without specific instruction from your vet. I’m sure he wants to re-test and see if the results are repeatable or if they spiked slightly from the stress of the vet visit. The Feline CRF website can give you more specific information about kidney values, testing and other indicators that you might find helpful in understanding the potential issues, but I urge you not to jump to any conclusions until your vet repeats the test. In any case, if there is a problem it appears to have been caught very early. You will find the CRF Information Center website linked under Kidney Disease on the page linked below.

Some of Iso’s distinct advantages over other anesthetic agents are lessened myocardial depressant and catecholamine sensitizing effects – cardiodepression generally is minimal at doses causing surgical planes of anesthesia, the ability to be used *safely* in cats with either hepatic or renal disease, and most importantly, its effects can be instantly reversed by just "turning it off"! The vast majority of the drug is eliminated via the lungs – not the kidneys. Only about 0.17% (not 17%) is matabolized in the liver. I can say, with reasonable certainty, Isoflurane is the *safest* anesthetic agent there is! Iso is the *only* anesthetic agent I allow to be used on my cats. I highly recommend it. btw, its more expensive – but well, well worth it. Best of luck. Phil.

Our 7 year old male cat (weighs 18 to 20 pounds) had dental surgery 5 or 6 months ago to remove some mid and back teeth because of gum problems (we were told this is a genetic problem that affects some cats). At the time the vet (now retired) did not do a blood test, which I am told is a common thing to do before you perform a procedure that involves anesthesia. So we don’t know his creatine level at that time. Today we took the cat in to have a lipoma removed from his back leg. It was previously established that it was not detrimental to the cat’s health, but we wanted it removed because it feels really icky and it might be getting larger. Anyways, they do a blood test and tell us that his creatine level is 280, and that the normal range is 70 to 220, and that we should come in again in 6 to 8 weeks and have it checked again. The cat did not eat anything during the 14 (or more) hours before the test. As a result of this high creatine level, the vet did not perform the lipoma removal. In talking to another vet, I am told the normal creatine range is 50 to 177. So now I ask - what is an acceptible creatine value for a 7 year old male cat that weighs 18 to 20 pounds and is active and not showing any signs of poor health? Is a high creatine level grounds to postpone minor surgery? What can happen in 6 to 8 weeks that would result in a change in creatine levels? Is there something we should do NOW to reduce this creatine level?
Response:
Normal ranges vary depending on the labs that perform the testing, so the norms should be compared on the results obtained from the lab. You have a legal right to the lab results if you ask your vet. Creatinin is one indicator of kidney function, and it would be appropriate for you vet to re-test before surgery. Anesthesia is metabolized through the kidneys, so it’s important for him to understand what’s going on before he administers any during surgery. I don’t think there is anything you should do to attempt to lower the levels without specific instruction from your vet. I’m sure he wants to re-test and see if the results are repeatable or if they spiked slightly from the stress of the vet visit. The Feline CRF website can give you more specific information about kidney values, testing and other indicators that you might find helpful in understanding the potential issues, but I urge you not to jump to any conclusions until your vet repeats the test. In any case, if there is a problem it appears to have been caught very early. You will find the CRF Information Center website linked under Kidney Disease on the page linked below. I hope it helps, and I wish you and your kitty the best of luck and http://www.geocities.com/Heartland/Pointe/9352/alphalinks.html – Hide quoted text — Show quoted text – > Our 7 year old male cat (weighs 18 to 20 pounds) had dental surgery 5 or > 6 months ago to remove some mid and back teeth because of gum problems > (we were told this is a genetic problem that affects some cats).
