Vet : Hi there, vet Andrew here. Do you know if the injection was ultrasound-guided? Also, was it steroid that was injected?
the vet didnt use ultrasound and not sure if steriod was use would this make the difference.
Vet : OK. First off, it's not essential to use ultrasound to do this procedure, it's just sometimes done. Secondly, if steroid were used in the joint then you could be seeing one of the side effects, which is increased thrist and hence increased urine production.
Vet : With regard to the peritonitis, it usually kicks in within a few days of any intervention, so it might well be associated with the needle, but again this is a recognised complication of pretty much any procedure involving a needle anywhere near the peritoneum, especially those involving steroids which damp down any immune response.
Vet : Sacral injections involve a large, 10-inch or so needle being inserted into a tight space, so they are difficult, hence the associated risks. I doubt that the bladder or gut were punctured, and even if they were it would be a small hole that should heal quickly, within days. But what could (and I stress 'could) have happened is that the needle entered the peritoneum (that is, the lining of the abdomen) at the top of the pelvis and set up an infection there.
Vet : The important thing is that he is improving. While reading your question I thought that maybe the rectum had been ruptured during a rectal examination pre-injection, but this doesn't appear to be the case as your vet will have told you this, as rectal rupture is potentially extremely serious. Your case sounds like a localised peritonitis which should recover with intensive therapy.
Vet : I hope this answers your question. If not, please post here and I'll be happy to give you more information. Regards, ***** *****
