Objective: This report describes the perioperative management of a dog with a right adrenal pheochromocytoma that presented with acute retroperitoneal hemorrhage, cardiac arrhythmia and hypertension. Additionally, a summary of pheochromocytoma and the idiosyncrasies of perioperative management of a pheochromocytoma are provided.
Summary: A 7-year old male, neutered, Dalmation was presented for acute collapse, abdominal pain and tachycardia. Physical examination findings were consistent with hypoperfusion concurrent with multiple cardiac arrhythmias and hypertension. Abdominal ultrasound revealed retroperitoneal effusion and a right adrenal mass intimately associated with the caudal vena cava. Incomplete right adrenalectomy was performed. Histopathology confirmed a pheochromocytoma.
Unique information provided: To the authors' knowledge, this is the first definitive report of acute retroperitoneal hemorrhage as the initial clinical manifestation of histologically confirmed adrenal pheochromocytoma in the dog. ( J. Vet Emerg Crit Care 2001; 11(3): 221–227 ) 相似文献

Objective: To determine the effect of storage on ammonia concentration in canine packed red blood cell (pRBC) units.
Design: In vitro and in vivo study.
Setting: University Veterinary Teaching Hospital.
Interventions: Ammonia concentration was measured in 7 units of canine pRBC prepared in citrate-phosphate-dextrose (CPD) and Adsola on Days 1 and 35 of storage. Ammonia was measured in 4 additional units of canine pRBC on Days 0, 7, 14, 21, 28, and 35. Plasma ammonia was also determined in 5 anemic dogs receiving pRBC.
Measurements and Main Results: Ammonia concentration increased from 73 ± 15 mmol/L (mean ± SD) on Day 1 to 800 ± 275 mmpl/L on Day (p<0.001). When measured every 7 days in 4 units of canine pRBC, ammonia concentration increased from 23 ± 8 mmol/L on Day 0 to 179 ± 13 mmol/L (Day 7), 276 ± 56 mmol/L (Day 14). 383 ± 47 mmol/L (Day21), 466 ± 30 mmol/L (Day 28), and 562 ± 27 mmol/L (Day 35) (p<0.05 for all comparisons). In a preliminary study, plasma ammonia concentration measured in blood samples from 5 anemic dogs without primary liver disease immediately before and after transfusion with 5–10 ml/kg of stored pRBC remained in the normal reference range.
Conclusions: The ammonia concentration in stored canine pRBC increased markedly with time. In this preliminary study, ammonia concentrations in dogs without primary liver disease did not increase above the reference range after transfusion with pRBC. 相似文献
