Three pigtail segments were acquired from dog erythrocyte antigen (DEA)‐1‐positive, DEA‐1‐negative, and feline type A blood units. Whole blood was collected from a healthy type B blood donor cat.InterventionsBlood from each rabbit recipient underwent a major crossmatch using standard tube crossmatch methodology with itself and the following donor blood types: rabbit, DEA‐1‐positive, DEA‐1‐negative, feline type A, and feline type B.Measurements and Main ResultsSelf‐crossmatches and crossmatches between rabbit recipients and conspecific donors were negative for hemolysis and agglutination. Crossmatches between rabbit recipients and canine and feline donors yielded no hemolysis but produced varying degrees of macroscopic and microscopic agglutination. Rabbit recipients had 1.4 (95% confidence interval: 1.1–1.8) times the risk of macroscopic agglutination when major crossmatched with canine blood compared to feline blood. No significant difference in agglutination was found between DEA‐1‐positive and DEA‐1‐negative or feline type A and type B donors.ConclusionsThese findings support allogeneic blood transfusions between rabbits being highly compatible and suggest rabbits have naturally occurring alloantibodies against both canine and feline red blood cells. However, feline red blood cells had a lower rate of in vitro incompatibility on major crossmatch, suggesting potentially higher in vivo compatibility if an emergency xenotransfusion is needed. Further prospective research is needed to determine if xenotransfusion is associated with a higher incidence of acute and delayed transfusion reactions in rabbits than allogeneic transfusions.}, journal={JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE}, author={Dannemiller, Nicholas G. and Ozawa, Sarah M. and Petritz, Olivia A. and Musulin, Sarah E.}, year={2024}, month={Feb} }

Abdominal ultrasound and computed tomography demonstrated evidence of a pancreatic mass with possible hepatic metastases. Attempts to aspirate the lesions under ultrasound guidance were unsuccessful, and the dog was hospitalized overnight for planned surgical resection of the presumed pancreatic tumor and biopsy of the hepatic lesions the following day. In response to a progressive increase in patient anxiety and agitation trazodone was prescribed ~5 mg/kg orally every 8 h and gabapentin at ~7 mg/kg every 8 h. As the dog continued to remain anxious dexmedetomidine at a dose of 1 mcg/kg was administered intravenously immediately followed with an infusion of dexmedetomidine at 1 mcg/kg/h. The anxious behaviors were successfully controlled with minimal cardiovascular side effects. Serial blood glucose measurements obtained during this time demonstrated euglycemia. The dog remained euglycemic while receiving dexmedetomidine for the remainder of the pre-operative period and for duration of hospitalization following surgical resection and biopsy.New or unique information providedThis case report demonstrates a possible role for dexmedetomidine to counteract hypoglycemia in dogs with insulinomas.}, journal={FRONTIERS IN VETERINARY SCIENCE}, author={Green, Randolph and Musulin, Sarah E. and Baja, Alexie Jade and Hansen, Bernie D.}, year={2023}, month={Apr} }

Two hospitals were studied: At North Carolina State University (NCSU), usage protocol dictates that the oldest units of PRBC (stored the longest) are prioritized for transfusion; whereas, at Ontario Veterinary College (OVC), units of PRBC are sorted according to age (days after collection) and PRBC are selected for transfusion according to clinician or technician discretion, such that PRBC could be administered after any storage duration, with no preference given to older units.ObjectiveTo evaluate differences in the age of PRBC administered to dogs at 2 veterinary hospitals with different age‐related PRBC usage protocols during a 1‐year period (2010–2011).Key FindingsThe average age of units of PRBC administered at NCSU was older than that at OVC (P < 0.001). Additionally, a higher number of PRBC units older than 14 days old were transfused at NCSU (P < 0.001), and the age of the oldest administered PRBC unit was also older at NCSU (P < 0.001). NCSU discarded approximately 15 expired PRBC units, whereas OVC discarded 96 expired PRBC units during the study period.SignificanceA standardized protocol for the priority administration of the oldest stored PRBC resulted in the administration of significantly older PRBC, but fewer expired units of PRBC were discarded.}, number={5}, journal={JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE}, author={Holowaychuk, Marie K. and Musulin, Sarah E.}, year={2015}, pages={679–683} }

Although 4 randomized controlled trials of varying sizes failed to find an association between RBC storage time and negative clinical outcomes, a recent meta‐analysis and numerous observational clinical studies have demonstrated that transfusion of old versus fresh stored RBCs is associated with an increased risk of morbidity and mortality, particularly among trauma victims and cardiac surgery patients. Potential clinical consequences of RBC transfusion following development of the storage lesion include risk of organ dysfunction, organ failure, infections, and death.Veterinary Data SynthesisExperimental animal models have contributed to the evidence supporting adverse consequences of the RBC storage lesion. Studies on relevant RBC storage issues such as the effect of different preservative solutions and leukoreduction have been completed. Transfusion with RBCs stored for 42 days increases mortality in dogs with experimental sepsis.ConclusionStorage of RBCs induces progressive biochemical, biomechanical, and immunologic changes that affect red cell viability, deformability, oxygen carrying capacity, microcirculatory flow, and recipient response. Most reports in the human and veterinary literature support the concept that there are deleterious effects of the RBC storage lesion, but additional studies with improved experimental design are needed to identify compelling reasons to modify current blood banking and transfusion practices.}, number={2}, journal={Journal of Veterinary Emergency and Critical Care}, publisher={Wiley}, author={Obrador, Rafael and Musulin, Sarah and Hansen, Bernie}, year={2014}, month={Nov}, pages={187–199} }

Some dogs have persistent infections without apparent clinical, hematological or biochemical abnormalities, whereas other dogs develop acute illnesses, persistent subclinical infections, or chronic debilitating diseases. The primary objective of this study was to screen healthy dogs for serological and molecular evidence of regionally important CVBDs. Clinically healthy dogs (n = 118), comprising three different groups: Gp I blood donor candidates (n = 47), Gp II healthy dog volunteers (n = 50), and Gp III stray dogs (n = 21) were included in the study. Serum and ethylenediamine tetraacetic acid (EDTA) anti-coagulated blood specimens collected from each dog were tested for CVBD pathogens. Of the 118 dogs tested, 97 (82%) dogs had been exposed to or were infected with one or more CVBD pathogens. By IFA testing, 9% of Gp I, 42% of Gp II and 19% of Gp III dogs were seroreactive to one or more CVBD pathogens. Using the SNAP 4DX® assay, Gp I dogs were seronegative for Anaplasma spp., Ehrlichia spp., and B. burgdorferi (Lyme disease) antibodies and D. immitis antigen. In Gp II, 8 dogs were Ehrlichia spp. seroreactive, 2 were infected with D. immitis and 1 was B. burgdorferi (Lyme disease) seroreactive. In Gp III, 6 dogs were infected with D. immitis and 4 were Ehrlichia spp. seroreactive. Using the BAPGM diagnostic platform, Bartonella DNA was PCR amplified and sequenced from 19% of Gp I, 20% of Gp II and 10% of Gp III dogs. Using PCR and DNA sequencing, 6% of Gps I and II and 19% of Gp III dogs were infected with other CVBD pathogens. The development and validation of specific diagnostic testing modalities has facilitated more accurate detection of CVBDs.

However, both of these routes have potential limitations. This study investigated the pharmacokinetics of diazepam following i.v., intranasal (i.n.) drop and atomized nasal administration in dogs. Six dogs were administered diazepam (0.5 mg/kg) via all three routes following a randomized block design. Plasma samples were collected and concentrations of diazepam and its active metabolites, oxazepam and desmethyldiazepam were quantified with high‐performance liquid chromatography (HPLC). Mean diazepam concentrations >300 ng/mL were reached within 5 min in both i.n. groups. Diazepam was converted into its metabolites within 5 and 10 min, respectively, after i.v. and i.n. administration. The half lives of the metabolites were longer than that of the parent drug after both routes of administration. The bioavailability of diazepam after i.n. drop and atomized nasal administration was 42% and 41%, respectively. These values exceed previously published bioavailability data for rectal administration of diazepam in dogs. This study confirms that i.n. administration of diazepam yields rapid anticonvulsant concentrations of diazepam in the dog before a hepatic first‐pass effect.}, number={1}, journal={JOURNAL OF VETERINARY PHARMACOLOGY AND THERAPEUTICS}, author={Musulin, S.
