Objectives – To describe changes in fresh frozen plasma (FFP) utilization over a 10‐year period at a veterinary teaching hospital. To evaluate the effect of FFP administration on specific laboratory parameters. Design – Retrospective observational study. Setting – University teaching hospital. Animals– Two hundred and eighty‐three dogs and 25 cats. Interventions – A hospital database search was performed for all animals receiving FFP during the study periods. Measurements and Main Results – Medical records of patients receiving plasma transfusions from 2006 to 2008 and from 1996 to 1998 were reviewed. Data collected included indications for transfusion, transfused volume, concurrent therapies, clinicopathologic data pre‐ and post‐transfusion, transfusion reactions, days of hospitalization, and outcome. FFP was administered to 112 dogs and 23 cats from 2006 to 2008 and to 171 dogs and 2 cats from 1996 to 1998. Significantly fewer patients received FFP for the treatment of hypoalbuminemia (2006–2008: 15% versus 1996–1998: 53%; P<0.001) or pancreatitis (2006–2008: 2% versus 1996–1998: 13%; P=0.001) and significantly more patients received FFP for coagulopathy (2006–2008: 80% versus 1996–1998: 31%; P<0.001) in the 2006–2008 group compared with the 1996–1998 group. For all patients receiving FFP, there was no difference in mean serum albumin concentration pre‐ and post‐transfusion. Median prothrombin time and activated partial thromboplastin time were significantly decreased post FFP administration. No association was found between the volume of plasma administered and outcome. Conclusions – FFP utilization has changed significantly over a 10‐year period. FFP was used most commonly in 2006–2008 for the correction of coagulopathy. FFP administration was associated with significant reduction in prothrombin time and activated partial thromboplastin time but did not significantly alter albumin concentration when administered at median doses of 15–18 mL/kg.  相似文献

Objective – To determine the incidence rate and prognostic significance of ionized hypocalcemia (iHCa) among septic dogs. Design – Retrospective study Setting – Veterinary teaching hospital Animals – Fifty‐eight septic dogs that were presented to Cornell University Hospital for Animals between January 2006 and December 2007. Procedure – Cases were diagnosed with sepsis if they exhibited 2 or more criteria of the systemic inflammatory response syndrome with a concurrent documented infectious focus. Cases were excluded if diagnosed with a concurrent illness reportedly associated with calcium derangements. Lowest, mean, and highest blood ionized calcium concentrations were recorded and statistically analyzed for an association with morbidity, as measured by duration of hospitalization and number of blood product transfusions, and outcome. In addition, the incidence rate of iHCa was recorded. Results – Of the 58 cases included in this study, iHCa was documented in 4 of 6 (67%) patients that died, 5 of 19 (26%) euthanized patients and 5 of 33 (15%) patients that survived to discharge, with an overall incidence of 24%. Dogs that died during hospitalization had more severe iHCa than patients that were discharged or euthanized as well as significantly lower mean ionized calcium concentrations than patients who were discharged. Severity of iHCa was also associated with a longer duration of hospitalization. The highest ionized calcium concentration was not associated with outcome. Conclusion and Clinical Relevance – This study is the first to document the incidence of iHCa among septic dogs. Because both low mean ionized calcium and the lowest documented ionized calcium concentration are associated with poor outcome, it is likely that both the severity and duration of hypocalcemia are important in these patients. Further prospective studies investigating the prognostic significance, etiology and treatment of iHCa among septic veterinary patients are needed to better understand its role in sepsis.  相似文献

OBJECTIVE: To compare survival rate, duration of hospitalization, and complications in dogs with pancreatic abscesses treated with omentalization with abdominal closure versus open peritoneal drainage and evaluate a pancreatitis severity score for potential prognostic value. DESIGN: Retrospective case series. ANIMALS: 15 dogs with pancreatic abscesses. PROCEDURE: Data regarding species, breed, age, initial clinical signs, CBC, serum biochemical abnormalities, pancreatitis severity score, anatomic location of the abscess, intraoperative bacteriologic culture results, treatment modality, postoperative complications, outcome (dismissed alive from the hospital, died in the postoperative period, or euthanized at surgery), and duration of hospitalization were evaluated. RESULTS: 6 dogs survived, 6 dogs died or were euthanized after surgery, and 3 were euthanized during surgery. Five of 8 dogs treated with omentalization and abdominal closure survived, and 1 of 4 dogs treated with open peritoneal drainage survived. In several dogs, treatment required additional surgical procedures, which did not appear to affect outcome. Postoperative complications were similar among survivors and nonsurvivors. Mean duration of hospitalization for dogs treated with omentalization and abdominal closure was less than that of dogs treated with open peritoneal drainage. Neither pancreatitis severity score nor any individual components of the score were associated with outcome. CONCLUSIONS AND CLINICAL RELEVANCE: Omentalization is a viable treatment option for pancreatic abscess in dogs. Furthermore, shorter hospitalization and better survival outcomes may make omentalization preferred over open peritoneal drainage.  相似文献

OBJECTIVE: To document reasons for use of fresh frozen plasma (FFP) in dogs and determine variables that apparently triggered the decision to use FFP. DESIGN: Retrospective study. ANIMALS: 74 dogs. PROCEDURE: Medical records of dogs that received FFP at a veterinary teaching hospital during a 3-month period were reviewed. RESULTS: The 74 dogs underwent 144 transfusion episodes (TE; a TE was defined as 1 day of transfusion therapy) and received 252 units (120 ml/unit) of FFP. Fresh frozen plasma was administered to provide coagulation factors (67 TE), albumin (91), alpha-macroglobulin (15), or immunoglobulins (19); for some TE, multiple clinical indications were identified. Variables that apparently triggered the decision to administer FFP included active hemorrhage with or without prolongation of coagulation times, low total plasma protein concentration, persistent vomiting associated with pancreatitis, and sepsis. Mean doses of FFP for each indication were between 8.5 and 9.4 ml/kg (3.9 and 4.3 ml/lb). Small dogs were generally given higher doses (mean dose, 13.9 ml/kg [6.3 ml/lb]) than large dogs (mean dose, 5.1 ml/kg [2.3 ml/lb]). Fifty (68%) dogs were alive at the time of discharge from the hospital. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that FFP plays an important role in the care of critically ill dogs. Because the supply of FFP is limited, guidelines for when administration of FFP may be clinically useful should be developed.  相似文献

Background: The putative role of the gut in amplification of systemic inflammation in acute pancreatitis is gaining credence, and intraluminal nutrition has been shown to decrease inflammation in experimental models of pancreatitis. Prepyloric feeding often is used in people with acute pancreatitis, but has not been evaluated in dogs. Hypothesis: Early intervention with enteral nutrition (EN) delivered proximal to the pylorus will be well tolerated in dogs with acute pancreatitis and provide justification for further larger trials. Animals: Ten dogs with severe acute pancreatitis in an open‐label, prospective pilot study. Methods: Dogs were treated with plasma transfusion and standard care, and then consecutively assigned to receive either EN via esophagostomy tube feeding or parenteral nutrition (PN). Outcome was used to determine optimal study size for future studies, and complications were compared between the 2 groups. Results: A significantly greater number of vomiting or regurgitating episodes occurred in dogs receiving PN. The dogs receiving EN did not demonstrate any noticeable postprandial pain. There were more catheter‐related complications in the PN group. There was no difference in outcome between the 2 treatments, and 43 dogs for each treatment would be required in future studies to determine a difference in outcome. Conclusions and Clinical Relevance: Early EN delivered proximal to the pylorus is well tolerated in dogs with severe pancreatitis and resulted in fewer complications than PN. Prospective trials in a larger cohort are justified to fully establish the potential benefit of early EN, preferably compared with minimal enteral nutrition.  相似文献

BACKGROUND: Lactate concentration often is quantified in systemically ill dogs and interpreted based on human data. To our knowledge, there are no published clinical studies evaluating serial lactate concentrations as a prognostic indicator in ill dogs. OBJECTIVES: Our objective was to perform a prospective study, using multivariate analysis, to determine whether serial lactate concentrations were associated with outcome in ill dogs requiring intravenous fluids. METHODS: Eighty sick dogs had lactate concentrations evaluated, using an analyzer that measures lactate in the plasma fraction of heparinized whole blood, at 0 hours and 6 hours after initiation of treatment. Severity of illness and outcome (survivor, nonsurvivor) were determined by reviewing the patient's record 2 weeks after admission. Lactate concentrations, age, body weight, gender, and severity of illness were evaluated using multivariate analysis to determine their effects on outcome. RESULTS: Dogs with lactate concentrations greater than the reference interval at 6 hours were 16 times (95% confidence interval = 2.32-112.71 times, P <.01) more likely not to survive compared to dogs with lactate concentrations within the reference interval. Lactate concentrations above the reference interval at 0 hours were not significantly related to outcome. However, hyperlactatemia that did not improve by > or = 50% within 6 hours was significantly associated with mortality (P = .024). CONCLUSION: Dogs with a lactate concentration higher than the reference interval at 6 hours were more likely not to survive. These results indicate an association between lactate concentration and outcome and emphasize the importance of serial lactate concentrations in evaluating prognosis.  相似文献

Objective – To test whether an initial plasma lactate≥6.0 mmol/L is associated with the presence of macroscopic gastric wall necrosis and overall survival in dogs presenting with gastric dilatation‐volvulus (GDV). Additionally, if no association was identified we sought to identify a different predictive initial plasma lactate concentration and to examine whether serial plasma lactate concentrations provide better prediction of survival. Design – Retrospective study over a 5‐year period (2003–2007). Setting – Urban private referral small animal teaching hospital. Animals – Eighty‐four client‐owned dogs with a diagnosis of GDV and plasma lactate measurements. Interventions – None. Measurements and Main Results – There was no statistically significant relationship found between survival and the presence of macroscopic gastric wall necrosis with the initial plasma lactate≥6 mmol/L. There was a significant relationship between the initial plasma lactate >2.9 mmol/L for predicting necrosis and <4.1 mmol/L for predicting survival to discharge. Forty dogs that had an increased initial plasma lactate (>2.5 mmol/L) also had a subsequent plasma lactate measured within 12 hours of presentation, with 37/40 dogs surviving and 70% of these surviving dogs having the subsequent lactate decrease by≥50% within 12 hours. The 3/40 that died failed to decrease their plasma lactate by≥50% from the initial blood lactate. Conclusion – The results of this study indicate that an initial presenting plasma lactate concentration≥6.0 mmol/L is not predictive of macroscopic gastric wall necrosis or survival in dogs presenting with GDV. A decrease in plasma lactate concentrations≥50% within 12 hours may be a good indicator for survival. Limitations to the study include its retrospective nature, the small number of patients, and the number of dogs that were euthanized rather than allowed to progress to a natural outcome.  相似文献

Objective – To evaluate the stability of canine and feline hemostatic proteins in freeze‐thaw‐cycled (FTC) fresh frozen plasma (FFP). Design – Prospective study. Setting – Veterinary Teaching Hospital. Animals – Nine blood donor dogs and 10 blood donor cats. Interventions – Whole blood was collected and separated into packed RBC and plasma units according to standard methods. Each unit of plasma was divided into 2 equal aliquots and frozen (?41°C). One aliquot from each donor (FTC) was then thawed and then refrozen (?41°C) until time of analysis. The second aliquot (nonfreeze‐thaw‐cycled; NFTC) remained frozen until time of analysis. The hemostatic proteins assessed included coagulation factors, anticoagulant factors (antithrombin and Protein C), and adhesive proteins (fibrinogen and von Willebrand Factor). The coagulant activities of factors II, VII, VIII, IX, X, XI, and XII were measured in modified one‐stage activated partial thromboplastin time or prothrombin time assays. Antithrombin and Protein C activities were measured in chromogenic substrate assays. Clottable fibrinogen was measured via the Clauss method, and von Willebrand Factor concentration (vWF:Ag) was measured in an ELISA. A paired t‐test was utilized to identify differences in factor activity or concentration between FTC FFP and NFTC FFP. Measurements and Main results – No clinically or statistically significant differences (all P>0.05) were identified between FTC FFP and NFTC FFP. Conclusions – Refreezing FFP within 1 hour of initial thawing appeared to have no deleterious effects on the hemostatic protein activity or content of that unit. Transfusion of FTC FFP is expected to provide the recipient with comparable replacement of hemostatic proteins as FFP that has remained frozen.  相似文献

Objective – To characterize the clinical presentation, management, and in‐hospital outcomes of dogs and cats diagnosed with acute congestive heart failure (CHF). Design – Retrospective study of animals seen between January 2007 and May 2008. Setting – Emergency service at a university teaching hospital. Animals – Ninety dogs and 55 cats with CHF. Measurements and Main Results – Patient characteristics, including age, clinical signs, clinicopathologic abnormalities, diagnostic testing, and outcome were recorded. Forty‐eight of the animals already were receiving cardiac medications at the time of presentation. The most common diseases represented were chronic valvular disease and cardiomyopathies. Cats had significantly lower median body temperature at admission compared with dogs (P<0.001). The most common abnormalities were elevated lactate (64%), elevated BUN (52%), hypochloremia (31%), hyperglycemia (27%), and elevated liver enzymes (26%). Many of these became even more prevalent during hospitalization. One hundred and sixteen animals were discharged from the hospital, for a survival rate of 80%. There was no survival difference between dogs and cats (P=0.39). Dogs that developed hypokalemia during hospital stay (P=0.04) were more likely to survive compared with those without hypokalemia and initial body temperature was lower for those cats that did not survive (P=0.02). Of those that did not survive, the majority were euthanized (n=25), while 4 dogs died. Conclusions – Dogs and cats presented to the emergency service with CHF had a high survival rate. In cats, initial body temperature was lower for those cats that did not survive. Although clinicopathologic abnormalities were common in both species, only dogs with hypokalemia had improved survival to hospital discharge.  相似文献

Objective – To determine the association of blood lactate with outcome and response to transfusion therapy in dogs with idiopathic immune‐mediated hemolytic anemia (IMHA). Design – Retrospective study. Setting – Urban veterinary small animal emergency hospital. Animals – One hundred and seventy‐three client‐owned dogs with IMHA. Interventions – None. Measurements and Main Results – Serial blood lactate concentration, therapeutic interventions, and outcome were recorded. Nonsurvivors were defined as those that died or were euthanized. One hundred and thirty‐three dogs (77%) survived, 35 (20%) were euthanized, and 5 (3%) died. One hundred forty‐five dogs (84%; 145/173) had a lactate concentration above the laboratory reference interval [0.46–2.31 mmol/L] on presentation. Blood lactate at presentation was higher in the nonsurvivors (median 4.8 mmol/L; 0.5–13.6) compared with survivors (median 2.9 mmol/L; 0.3–13.2) (P<0.01). All dogs presenting with hyperlactatemia that normalized (<2.0 mmol/L) within 6 hours of admission survived, whereas, 71% of dogs that had a persistent hyperlactatemia at 6 hours survived (P=0.034). Lactate was positively correlated with age, BUN, and alkaline phosphatase, and inversely correlated with PCV. Receiver operating curve analysis for lactate concentration at admission as a test for outcome had an area under the curve of 0.69 with an optimal lactate cutoff concentration of 4.4 mmol/L correctly predicting outcome 73% of the time (sensitivity 60%, specificity 77%). Conclusions – Lactate concentration at presentation was significantly higher in nonsurvivors than survivors. Lactate was significantly correlated with previously reported outcome variables but lactate concentration at admission, as a predictor for outcome was less than optimal. However, serial lactate concentration measurements may be more predictive as patients with persistent hyperlactatemia 6 hours after admission were less likely to survive. Prospective studies evaluating serial lactate concentration while controlling for other variables may provide further insight into lactate measurement as a prognostic indicator in animals with IMHA.  相似文献

OBJECTIVES: To determine incidence and identify predisposing factors for sterile hemorrhagic cystitis (SHC) in dogs with lymphoma that were treated with cyclophosphamide and to evaluate whether furosemide administered i.v. concurrently with cyclophosphamide decreased the incidence of SHC. DESIGN: Retrospective study. ANIMALS: 216 dogs with lymphoma. PROCEDURE: Medical records of dogs with lymphoma that received cyclophosphamide chemotherapy in accordance with 1 of 2 protocols, with or without concurrent i.v. administration of furosemide, were examined. Data for the 2 groups were analyzed to determine the incidence and predisposing factors (age, breed, sex, weight, previous or preexisting disease, previous or preexisting urinary tract infection, neutropenia, azotemia, dose, and number of cyclophosphamide treatments) for cyclophosphamide-associated SHC. RESULTS: Cyclophosphamide-associated SHC developed in 12 of 133 (9%) dogs that had not received concurrent administration of furosemide and cyclophosphamide treatments; of the 83 dogs that had received furosemide, only 1 (1.2%) developed SHC. Dogs receiving cyclophosphamide and furosemide concurrently were significantly less likely to develop SHC than dogs that did not receive furosemide. Dogs with previous or preexisting immune-mediated disease were significantly more likely to develop cyclophosphamide-associated SHC. CONCLUSIONS AND CLINICAL RELEVANCE: Analysis of results suggested an association between i.v. administration of furosemide concurrently with cyclophosphamide and decreased incidence of cyclophosphamide-associated SHC. Incidence of cyclophosphamide-associated SHC was similar in treated dogs that did not receive concurrent furosemide to that observed for other studies in which cyclophosphamide was administered orally. Cyclophosphamide-associated SHC appeared to develop early during the course of chemotherapy when furosemide was not administered concurrently with cyclophosphamide.  相似文献

Background – This study was performed to document the frequency and severity of limb injuries that occur when dogs come in contact with metal landscape edging. A retrospective study from 1997 to 2007 was performed at Colorado State University veterinary teaching hospital. Sixty dogs were admitted to hospital for traumatic limb injuries resulting from metal landscape edging identified by a computerized medical records search. Key Findings – Most dogs were young, large breed dogs. All 60 dogs suffered traumatic pedal lacerations when contacting metal landscape edging, the majority of which occurred on the forelimbs. Eighty‐five percent required surgical repair. All 60 dogs were discharged from the hospital and 30 were available for long‐term follow‐up. While most dogs healed with a perfect cosmetic outcome, 3 dogs with tendon involvement developed residual digital deformities. Significance – Dogs are at risk of injury when exposed to metal landscape edging. Severity of pedal injury determines treatment protocol and prognosis for recovery.  相似文献

Objective – To determine if changes in viscoelastic variables are associated with abnormalities observed in the standard coagulation profile and patient outcome in foals with suspected septicemia. Design – Prospective clinical trial during 2003 and 2004 foal season. Setting – Neonatal intensive care unit at a veterinary teaching hospital. Animals – Thirty critically ill foals <72‐hour‐old admitted sequentially meeting criteria for systemic inflammatory response associated with infection. Interventions – Hemostatic evaluation, using standard coagulation testing and viscoelastic analysis, was performed at admission, 24 hours following admission, and 48 hours following admission in critically ill foals. Standard coagulation tests included platelet count, prothrombin time, activated partial thromboplastin time, fibrinogen, fibrin(ogen) degradation products, and antithrombin. Data collected from viscoelastic analysis included time to initial clot formation (ACT), clot rate, and platelet function. Signalment, blood culture results, clinicopathologic data, and outcome were collected from medical records. Equality of populations test was used to determine associations between coagulation tests and blood culture status/outcome, as well as between viscoelastic parameters and coagulopathy, blood culture status, and outcome. Logistic regression was used to quantify associations. A significance level of P<0.05 was used. Measurements and Main Results – Foals with decreasing clot rate (CR) over the sample period were more likely to be euthanized or die (P=0.02). Foals with prolonged ACT (P=0.03), and decreased CR at admission (P=0.047), were more commonly coagulopathic. Identification of coagulopathy on admission (P=0.02), or persistence of hemostatic dysfunction 48 hours later (P=0.04), was associated with death. Conclusions – Viscoelastic coagulation evaluation could be used in a neonatal intensive care unit setting to further characterize coagulopathy, and identify foals at higher risk for poor outcome.  相似文献

Olfactory bulb lesions were diagnosed in four dogs presented for generalized seizure disorders. Surgery was performed on each dog using a transfrontal craniotomy. A free fascial-fat graft was used to cover the dural defect resulting from surgery. No major complications were observed during the immediate postoperative period. The histopathologic diagnosis in each case was meningioma. Generalized seizures recurred in all dogs, and three dogs were euthanized for this reason from 9 to 29 weeks postoperatively. One dog was euthanized 12 weeks after surgery due to pancreatitis and pneumonia. Necropsy showed that two dogs had recurrent olfactory bulb meningiomas, one dog had a meningioma of the opposite olfactory bulb, and one dog was tumor free.  相似文献

OBJECTIVE: To evaluate a method of aerobic bacteriologic culture of epidermal collarette specimens from dogs with superficial pyoderma and compare results with those for aerobic bacteriologic culture of abdominal skin specimens in healthy dogs. DESIGN: Prospective study. ANIMALS: 22 dogs with epidermal collarettes and 24 healthy dogs. PROCEDURE: Dry sterile cotton swabs were rolled across epidermal collarettes or hairless areas of abdominal skin in healthy dogs and submitted for aerobic bacteriologic culture. Hemolytic colonies of gram-positive-staining cocci were tested for catalase production, and if results were positive, a coagulase test was performed. Colonies with coagulase activity were tested for the ability to ferment mannitol. Antimicrobial susceptibility testing was performed on all Staphylococcus spp that were isolated. RESULTS: S. intermedius was isolated from collarettes in 18 of 22 dogs with superficial pyoderma but not from healthy dogs. Estimated sensitivity and specificity of the culture method were 81.8% and 100%, respectively. There were no significant differences in the ability to culture S. intermedius, the number of S. intermedius isolates without resistance to antimicrobials, and the number of S. intermedius isolates resistant to penicillin G when comparing dogs with superficial pyoderma for the first time and dogs with recurrent pyoderma, dogs that did or did not receive concurrent antimicrobials, and dogs with and without underlying allergic disease. CONCLUSIONS AND CLINICAL RELEVANCE: Bacteriologic culture of epidermal collarette specimens was a simple and reliable method for identification of S. intermedius in dogs with superficial pyoderma, regardless of history of pyoderma or current antimicrobial use.  相似文献

Background – Ciclosporin is widely used in the management of canine atopic dermatitis. In humans, ciclosporin therapy has been linked to disturbances in calcium metabolism and resultant skeletal disorders. Objectives – The objective of this study was to assess calcium homeostasis in dogs before and after a 6 week course of once daily oral ciclosporin at the licensed dose (5 mg/kg). Animals – Sixteen client‐owned dogs with spontaneous atopic dermatitis. Methods – Serum concentrations of calcium, phosphate, creatinine, 25‐hydroxyvitamin D, 1,25‐dihyroxyvitamin D and plasma concentrations of ionized calcium and parathyroid hormone (PTH) were measured, together with the urinary fractional excretion of calcium and phosphate. The extent of skin lesions was scored using the Canine Atopic Dermatitis Extent and Severity Index (CADESI)‐03 and the degree of pruritus by the Edinburgh Pruritus Scale prior to and at the end of the study. Results – The CADESI‐03 and the Edinburgh Pruritus Scale scores decreased satisfactorily in all dogs by the end of the study. Plasma PTH concentrations were significantly increased (P = 0.02) following ciclosporin treatment, whereas all other biochemical parameters were not significantly different from their starting values. The increase in PTH was mild in most cases and the proportion of dogs that had a PTH concentration above the reference range was not significantly different following treatment. Conclusions and clinical importance – This study indicates that ciclosporin has minimal impact on calcium metabolism in dogs with atopic dermatitis when used at the licensed and clinically effective dosage for 6 weeks.  相似文献

Objective – To identify and characterize the syndrome of immune‐mediated hemolytic anemia (IMHA) with concurrent severe thrombocytopenia (≤15.0 × 109 platelets/L; [15.0 × 103 platelets/μL]), and to evaluate prognostic factors, clinicopathologic findings, complications, treatment, outcome, and survival of dogs with this hematologic disorder. Design – Retrospective, observational study. Setting – Veterinary teaching hospital. Animals – Twelve client‐owned dogs with IMHA and severe thrombocytopenia (≤15.0 × 109 platelets/L; [15.0 × 103 platelets/μL]), without evidence of overt disseminated intravascular coagulation. Interventions – The following data were recorded and analyzed from the electronic medical record: signalment, history, concurrent diseases, clinical signs at presentation, clinicopathologic data, diagnostic testing, radiographic findings, treatment modalities, length of hospitalization, complications, and clinical outcome. All dogs were treated with immunosuppressive doses of corticosteroids. Measurements and Main Results – Twelve dogs were identified with the diagnosis of IMHA and severe thrombocytopenia; of these, 9 (75%) survived, 3 (25%) were euthanized, and none died. Dogs that survived were significantly younger than nonsurvivors (P=0.03). There were no specific clinical signs or therapies associated with survival. Conclusions – Dogs in this study had a mortality rate similar to reported rates for dogs with either disease alone. Overall, younger dogs were more likely to survive. No association between different treatment modalities and overall survival was identified.  相似文献

Computed tomographic angiography (CTA) has recently been shown to be a useful tool in the diagnosis of acute canine pancreatitis, the identification of pancreatic necrosis, and the detection of sequelae. Evidence of pancreatic necrosis on CTA has been shown to be correlated with a poorer outcome in both humans and dogs and early diagnosis and intervention may improve outcomes. In humans, pancreatic necrosis is typically evident on CTA within 48 h of clinical signs, thus, repeat CTA examinations are often performed to identify pancreatic necrosis that may not have been evident on CTA examinations performed early in the course of disease. Published information investigating the timing of CTA examinations and the use of serial CTA in dogs with acute pancreatitis is lacking. In this prospective, longitudinal study, CTA examinations were performed at the time of hospitalization and repeated 3‐5 days later in 11 dogs suffering from acute canine pancreatitis to determine if pancreatic necrosis or sequelae are under diagnosed on examinations performed at the time of hospitalization. Computed tomographic angiography studies were evaluated for changes in pancreatic size, pancreatic contrast enhancement, and peri‐pancreatic tissues and vessels. The only statistically significant difference between the initial and repeat CTA examinations was the improvement of fat stranding on the repeat CTA examinations (P < .045). Based on these results, CTA performed at the time of admission is likely adequate in the diagnosis and evaluation of dogs with acute pancreatitis. Repeat CTA examinations are unlikely to add additional information in the absence of worsening clinical signs.  相似文献
