Lasix for Edema

Zoo Nanny · 08-13-13, 04:08 PM

Has anyone had their snake or lizard treated with Lasix for edema. If so was it given by injection or orally?

Do you know the underlying cause of the edema? Renal? Cardiac? Liver?

Not 100% sure but the general concensus is cardiac

IDK about reptiles, however, in human medicine, lasix can be given both routes. The oral route though can be a little "iffy" when bowel wall edema is also going on, this messes up absorption through the bowel and the effect will be lessened. If it's a cardiac origin, i would suppose either way would work. Can you give more info on animal? I would guess your reptile vet would be following renal function and electrolytes (K+, Na+) as lasix can cause a potassium depletion and bring on a whole new set of bad stuff.

Potassium depletion doesn't happen in reptiles as a rule from the use of lasix. Renal function would still need to be followed for fear of dehydration. Blue Tongue Skink at least 17 years old. Symptoms of breathing heavy with small amount of mucus on lip seen last Monday evening, Tuesday am appeared to be fine no mucus noticed eating well. Tuesday pm mucus back breathing appeared labored. Vet on wednesday symptoms increased quickly during the day. Blood panels and full body xrays all were inconlusive or within normal "lizard range" Very little research and treatment has been done on BTS once seniors. Currently 2 exotic vets have looked at him with consultation with 2 zoo vets one a specialist in cardiology the other reptiles. Additional consultations done with 4 other local exotic vets and two EKG specialist. All come to the conclusion that it is most likely heart failure due to advanced age. Treated with IM baytril for 5 days. At this point I just would like to make him more comfortable and the one reptile zoo vet has used lasix with positive results to decrease edema.

That's interesting about the excretion of potassium in reptiles with a diuretic. Sounds like you have your bases covered. Keeping comfortable for now sounds appropriate.

Sadly that's about all we can do for him. I was really praying that we would find some underlying infection that could be treated. He's a very sweet animal with a really good disposition. The vet and vet tech were intimidated by him initially because of his size and the reputation of skinks being bitey. That I had never heard before. It took some reassuring to them that he was not going to turn and remove any digits! I think they were amazed at how passive he was. He is just over 24 inches and ways 1 kg. There has been a good deal of interest in his case with a number of vets due to the limited numbers of seniors around. I was surprised when the vets were telling me that most BTS die here by age 10. None of the vets here in MA that are involved have even seen an adult let alone a senior.

This as got to be the most educational thing i read on here in a while. Thanks you both.

Nanny keep us updated and i love to see some pictures of him.

I would LOVE to see an ECG on a Blue Tongue Skink....
Having said that, I am sorry you are having to go through this.

Zoo Nanny · 08-13-13, 08:52 PM

Oops ECG, it would be interesting. Their heart rates are so soft/quiet(?) that they can not be heard with a regular stethoscope. I wonder if they could be heard with a fetal monitor. In the past week I've learned an incredible amount of information on skinks while still learning very little. I've also learned that there are some awesome vets out there that are willing to help even without compensation. To date with all of the vets involved I've only paid one. If anyone in the Northeast is looking for a good exotic vet I can give the names of a few now that are awesome!
This is a picture taken this morning. You can see the edema on his throat.

ECG/EKG all the same

(Latin or Greek)
It's all good. Sounds as if you're doing the best for him that you can. I hope things go well.

I've got to agree with marvel;

these posts are the real reason i'm on this forum. I know not everyone is into the medical stories and vet visits and answers, but it is really heartening to see someone who cares about their animal, is doing everything they can for it, AND is bringing more options to other reptiles owners and vets.
It will be very interesting to see how he responds to the drug, I'm really hoping its able to give him some comfort and you some piece of mind, OP.
Thank ou for sharing this with us.

Thank you MDT for the information on the administering of the drug. And thank you all for the support. I'm not doing anything that most folks here wouldn't also do for their charges. It's what we sign up for when we bring them home to live with us.

Precious received his first injection of Lasix this morning. 5mg dose per kg is the doseage prescribed. If it's going to help him I should see a diffence in the edema by this evening. I'm keeping my fingers. Enroute home from the vets he pooped in the carrier. It was not of the normal consistency or color and had undigested food in it. I'm not feeling very optimistic at this point. His ambient temps have been an average of 88-90 during the day and 78-80 at night. This has been on the high side due to being in the smaller tank and trying to keep his temps up until we figure out what's going on with him.

ZN....interesting. My question is since reptiles excrete urates rather than urine, how does Lasix exert its effect. In humans, Lasix is acting in the tubules (Loop of Henle) in the kidney and through a butt-load of really boring molecule/electrolyte transporting, it makes you pee. I have zero idea what reptile renal physiology is, but if the desired goal is to increase urine output to eliminate excess fluid, does it work the same in reptiles?
