From a Technician's Perspective

Emergency practice is completely different from the day practice. The animals in the hospital are usually very sick or severely injured.

The following article appeared in The Dallas Morning News.

By Monday, the furry patients would have stolen staffers' hearts and taxed their skills. As in human hospitals, there would be long, uncertain waits, some ending in relief, others in sorrow.

Owner Lupe Zepeda of Rowlett said his older poodle had been scaring the puppy away from food and water at home. Eventually, the pup had stopped eating altogether. When he arrived at the clinic Saturday morning, Coco was near death...

Interesting Case

LaylaSignalment: 4 YR FS DSH

History: “Layla” was an adult stray cat, wandering the neighborhood when she was taken in by her good hearted owner. For the first two years in her new home “Layla” was healthy and received regular veterinary care. Layla’s owner began to notice weight loss and then blood tinged urine outside the litter box. At that time, “Layla” also began hiding and avoiding all attention. “Layla” was taken to her regular veterinarian where her blood work revealed anemia. It was suspected that she had a blood borne parasite or an autoimmune disorder, immune mediated hemolytic anemia (IMHA). She was prescribed the antibiotic Doxycycline and a vitamin supplement. Her owner observed labored breathing and increasing lethargy the following morning, “Layla” was referred to the ER.

Exam: She presented depressed with fair pulses, pale mucus membranes and increased bronchovesicular sounds in dorsal lung fields.

Diagnostics: The CBC revealed anemia (Hct 14%) and thrombocytopenia (62 K/uL). Hyperbilirubinemia (0.8 mg/dL) and hyperglycemia (266 mg/dL) were noted on the chemistry analysis.

DieselHistory:  Diesel presented with facial swelling redness and hives on his chest and abdomen.  His owner stated that he was outside for approximately 1 hour, and noted the swelling after 30 minutes. Owner gave him a bath the he began rubbing his face.  Diesel began developing hives on the car ride to the clinic. The family’s yard is small and in a residential area, and they are not aware of any toxins or abnormal items that he could have ingested.  Diesel had had no recent changes in his diet, no flea products applied, and no vomiting.  He has no history of allergies or any other medical issues. He is also current on vaccinations and takes a monthly heartworm preventative.

Exam:  All of the abnormalities found were associated with Diesel’s skin.  He had generalized red skin (erythema) which was most pronounced on his head/neck, and swelling (angiodema) which was primarily affecting his face.  He was itchy (pruritic) and also had hives (urticaria).  Otherwise Diesel appeared to be a normal Boston Terrier.
