apologies for the cross post, but hoping some one has encounter this before. my ferret Sand went in for surgery last wed to remove a mass in his abdomen. ultrasound a year ago shows a cyst on his kidney which is now attached to the mass. maybe slow growing mass. has inflammatory fluid in it. after Sand was given pre-med and anesthesized, his heart rate slowed (it was 36 for a few secs) and he did not respond to glyco (sp?) initially but did when they try atropin (sp?), so they deemed it was too dangerous for surgery and brought him back. yesterday he went in for electrocardiographs and radiographs to see if it is heart problems, no premeds were given and 40 minutes after he was under, his heart rate start to drop, this time he responded to glyco and his heart rate never dropped below 150. his radiographs and ecg are completely normal. the cardiologist doesn't think it is a heart problem, although a cardio-ultrasound can be used to rule it out completely. another possibility is that he is just hyper sensitive to drugs. if he goes for surgery again then they will use sevofluorine and monitor him with a ecg machine, no pre-meds andtake other precautions as well. Sand in the past not only had vaccine reaction to canine distember (Fervac), but to rabies as well. I'm hoping some one has encounter similar things and can relate their experience, if there are other suggestions as well. I think he will need he surgery, but I'm really feeling paranoid. thank you for your time. // ************************************************ // Selina, Birch, Dief, Sprite, Sand and Bear // missing Storm // http://www.cgl.uwaterloo.ca/~ssiu [Posted in FML issue 3916]
