Objective: To report on the use of 25% human serum albumin (25% HSA) (Plasbumin®), associated outcome, and efficacy in raising serum albumin and systemic blood pressure (BP) in critically ill dogs and cats. Design: Retrospective clinical study. Animals: Client‐owned cats and dogs. Interventions: Administration of 25% HSA. Measurements and main results: The medical records of 66 animals (64 dogs, 2 cats) at the Ontario Veterinary College, which received 25% HSA (Plasbumin®) from June 1997 to December 2001 were reviewed for age, body weight, clinical problems, albumin and globulin (g/L) levels pre‐ and within 18‐hour post‐transfusion and upon discharge from hospital, total solids (TS), systolic and diastolic BP pre‐ and post‐transfusion total volume administered, adverse reactions, blood products and synthetic colloids used, and outcome. Twenty‐five percent HSA was prescribed for a range of clinical problems, which were grouped into 6 categories for analysis. The age range was 4 months–12 years and body weight range 1.4–65 kg. The maximum volume administered to any dog was 25 mL/kg, mean volume administered was 5 mL/kg, maximum volume given as a slow push or bolus was 4 mL/kg with a mean of 2 mL/kg volume. The range for a constant rate infusion (CRI) was 0.1–1.7 mL/kg/hr over 4–72 hours. Forty‐seven (71%) animals survived to discharge; 11(16%) were euthanized, and 8 (12%) died. Serum albumin and TS increased significantly (P<0.0001) above pre‐transfusion levels as did systolic BP (P<0.01). Conclusions: Twenty‐five percent HSA can be safely administered to critically ill animals, and an increase in albumin levels and systemic BP can be expected. 相似文献

Relationship between assays of inflammation and coagulation: A novel interpretation of the canine activated clotting time 下载免费PDF全文

The processes of inflammation and coagulation are known to be interconnected through several mechanisms; however, the influence of inflammation on the interpretation of coagulation assays remains unknown. Blood was collected from 87 dogs admitted to a tertiary referral intensive care unit (ICU) and 15 control dogs. The association between 2 markers of inflammation [mature neutrophil count and C-reactive protein (CRP)] and 5 coagulation parameters [activated clotting time (ACT), prothrombin time (PT), activated partial thromboplastin time (aPTT), antithrombin (AT), and platelet count (plt)] were evaluated through correlation analysis. The study population was then divided into 4 groups based on severity of ACT prolongation with comparisons to all other variables assessed through an analysis of variance (ANOVA) test. A strong correlation for a biological system was demonstrated between ACT and CRP (r = 0.66; P < 0.0001). Statistically significant results were also found between aPTT and AT with the markers of inflammation, but the correlations were weaker. Within ACT groups of increasing severity, higher CRP concentrations (P < 0.0001) and lower AT activities (P < 0.0001) were identified. This study provides evidence for an association between assays of inflammation and coagulation and suggests that modification of our traditional interpretations of coagulation assays may be required. As a point-of-care test, ACT is a simple and inexpensive tool that can be used to assess an underlying inflammatory or hemostatic process. 相似文献

Objective – The primary objective of this study was to assess the feasibility of noninvasive mechanical ventilation (NIV) in cats. The secondary objective was to determine whether cardiovascular parameters and anesthetic drug requirements associated with noninvasive ventilation differ from those associated with invasive ventilation. Design – Randomized, cross‐over design. Setting – A research laboratory in a veterinary teaching hospital. Animals – Eight healthy adult cats, 3 intact females and 5 intact males, weighing between 3 and 6 kg, were used. Interventions – Each cat was randomly assigned to NIV via nasal mask, or invasive ventilation using an endotracheal tube. Mechanical ventilation was performed for 6 hours. Anesthesia was provided using continuous infusions of propofol and butorphanol. After a minimum 9‐day washout period, the procedure was repeated using the alternate ventilation interface. Measurements and Main Results – Cardiovascular parameters (heart rate, rectal temperature, direct arterial blood pressure), arterial blood gases, drug requirements, sedation score, and ventilation parameters, were monitored throughout the procedures. These values were evaluated using ANCOVA for repeated measures. All cats were effectively ventilated using NIV. There were no significant differences in cardiovascular parameters, drug requirements, or sedation scores between groups. Although PaCO2 values did not differ, PaO2 values were significantly higher in the invasively ventilated group. Inspiratory tidal volumes were similar between groups, whereas expiratory tidal volumes were significantly lower in the NIV group. Inspiratory pressures were significantly higher in the NIV group. Respiratory frequency was significantly higher in the invasively ventilated group. Conclusions – NIV of cats is possible. However, currently it does not confer any cardiovascular benefit over invasive ventilation and drug requirements are similar. Use of a correctly fitted mask is essential for successful NIV as air leaks account for the observed discrepancy between inspiratory and expiratory volumes. Further investigation into this modality is warranted. 相似文献

CASE HISTORY: Twelve of 150 goat kids, 4–10 days old, died 3 days after disbudding with a hot iron. Another 18 kids had been ill the previous day but survived following antibiotic therapy. Five of the dead kids were necropsied. PATHOLOGICAL FINDINGS: There was necrosis and haemorrhage of the skin, subcutaneous tissues and frontal bone at disbudding sites in all five kids examined post mortem. Beneath disbudding sites in 4/5 kids there were bilateral, dark red, often cavitated areas of necrosis extending deep into the frontal cortex of the brain. Histologically, these areas consisted of coagulation necrosis, haemorrhage, vascular thrombosis and suppurative inflammation. Numerous bacteria, predominantly large Grampositive rods, were present in the necrotic brain tissue. In the remaining kid, bilateral areas of yellow discolouration and flattening of gyri in frontal lobes corresponded histologically to extensive polioencephalomalacia. A mixed growth of aerobes and anaerobes was cultured from the brain of one kid with suppurative lesions. CLINICAL RELEVANCE: Thermal disbudding of neonatal kids is widely practised in dairy goat herds and is considered the method of choice for disbudding in New Zealand. However, the skull of goat kids is much thinner than that of calves and the safety margin for thermal injury to the brain is markedly reduced. This report highlights the risks associated with the technique and its potential as a welfare issue. 相似文献
