OBJECTIVE: To identify clinically relevant variables and treatments for dogs bitten by prairie rattlesnakes (Crotalus viridis viridis). DESIGN: Retrospective study. ANIMALS: 100 client-owned dogs. PROCEDURE: Records of dogs evaluated for rattlesnake envenomation from 1989 to 1998 were reviewed. Analysis was performed to test for significant associations among clinical variables or treatments and cell counts, costs, and duration of hospitalization. RESULTS: Most prairie rattlesnake bites occurred between May and September. Dogs were 3 months to 12 years old (median, 3.7 years); most were bitten on the head in the late afternoon. There was no sex predilection. Median time to evaluation was 1 hour (range, 15 minutes to 13 hours). Swelling in the area of the bite was the primary physical abnormality. Principal initial laboratory findings were echinocytosis, thrombocytopenia, leukocytosis, and prolonged activated clotting time. Ninety-four dogs were hospitalized; 48 were discharged the following day. Antimicrobials and crystalloid fluids, glucocorticoids, antihistamines, and antivenin administered i.v. were the most commonly used treatments. One dog died, and small dogs were hospitalized longer than large dogs. Antivenin administration was not significantly associated with duration of hospitalization but was associated with higher platelet counts after treatment and higher total hospital costs. CONCLUSIONS AND CLINICAL RELEVANCE: Prairie rattlesnake envenomation in dogs is associated with high morbidity rate but low mortality rate. The efficacy of administration of antivenin for dogs with bites from this snake species is questionable.  相似文献

OBJECTIVE: To characterize the use of antiemetic agents in dogs with canine parvovirus (CPV)-associated enteritis in a veterinary teaching hospital. DESIGN: Retrospective case series. ANIMALS: 77 dogs with CPV-associated enteritis. PROCEDURE: Medical records of 560 dogs with confirmed CPV-associated enteritis that were admitted to a veterinary teaching hospital were reviewed. Exclusion criteria included vaccination against CPV infection within the preceding 2 weeks, hospitalization for < 24 hours or removal from the hospital against advice, or an incomplete record. Signalment, duration of hospitalization, and daily antiemetic administrations were assessed; WBC counts and clinical findings were used to classify dogs as having systemic inflammatory response syndrome (SIRS). RESULTS: 77 dogs were included in the study; 55 (71%) received antiemetics (53 received metoclopramide at least once). Seventy-one dogs survived, and 6 dogs died (all 6 received antiemetics). Compared with dogs that did not receive antiemetics, duration of hospitalization was significantly longer for antiemetic-treated dogs. Daily values of rectal temperature and heart and respiratory rates did not predict administration of antiemetics or duration of hospitalization; however, compared with survivors, SIRS developed more frequently among nonsurvivors. Assessment of emetic events recorded hourly for 17 dogs indicated that antiemetic treatment did not control emesis. CONCLUSIONS AND CLINICAL RELEVANCE: Many dogs with CPV-associated enteritis had persistent vomiting despite antiemetic administration. The apparent difference in duration of hospitalization between antiemetic-treated dogs and other dogs may reflect a difference in disease severity between groups, although antiemetic-associated adverse events (e.g., signs of depression, hypotension, and immune modulation) may prolong hospitalization.  相似文献

Objective – To assess the utility of nasotracheal tubes in postoperative oxygen supplementation in dogs following corrective surgery for brachycephalic syndrome. Design – Retrospective study 2003–2007. Setting – University teaching hospital. Animals – Thirty‐six client‐owned dogs that underwent corrective surgery for brachycephalic syndrome. Interventions – None. Measurements and Main Results – Medical records were reviewed for animals that underwent surgical interventions for brachycephalic syndrome including palatoplasty, ventriculectomy, and rhinoplasty. Data collected included signalment, presenting complaints, analgesic and surgical interventions, type of supplemental oxygen therapy, complications and mortality occurring during hospitalization. A nasotracheal tube (NTT) was placed in 20 dogs at the end of surgery; 16 dogs received other forms of oxygen supplementation (8) or no oxygen supplementation (8) during recovery. The total number of postoperative complications was similar in both groups (8/20 dogs with NTTs and 7/16 in those without NTTs). However, respiratory distress was observed in 5 dogs without NTTs but was not observed in any dog while an NTT was in place. One dog in each group died postoperatively. Conclusion – Placement of an NTT was found to be easy and may offer benefit in dogs with brachycephalic syndrome as a noninvasive means of delivering oxygen. The use of NTT may minimize severe postoperative morbidity, in particular by reducing postoperative respiratory distress.  相似文献

CASE DESCRIPTION: 2 dogs were evaluated because of vomiting and lethargy (a Toy Poodle; dog 1) and acute respiratory distress, vomiting, and anorexia (a Chihuahua; dog 2). Dog 1 had been exposed to a commercial hydrocarbon waterproofing spray 24 hours before the development of clinical signs, and dog 2 was examined 18 hours after exposure to a waterproofing spray containing heptane, a highly flammable liquid hydrocarbon. CLINICAL FINDINGS: In both dogs, major gastrointestinal tract abnormalities were ruled out but respiratory status worsened. Thoracic radiography revealed a diffuse interstitial pulmonary pattern, and hypoxemia was detected. TREATMENT AND OUTCOME: Hospitalization for monitoring and care was required for both dogs. The dogs recovered with supportive care, which included administration of oxygen, fluids, and bronchodilators. Additionally, dog 1 received glucocorticoids via inhalation and supplemental enteral nutrition, whereas dog 2 was treated with an antimicrobial. CLINICAL RELEVANCE: The dogs of this report developed hydrocarbon pneumonitis following exposure to waterproofing sprays. Such sprays contain potentially toxic hydrocarbons. The severity of the adverse effects associated with exposure may have been amplified because the dogs were physically small and were exposed to a relatively large amount of aerosolized spray within small areas. Development of chemical pneumonitis in pet animals is best prevented by application of waterproofing sprays in well-ventilated or outdoor areas from which pets have been excluded. With prolonged hospitalization and considerable monitoring and care, affected dogs can recover from these exposures.  相似文献

ObjectiveTo investigate the statistical association of severe intraoperative hypoxemia in thoracic surgery with mortality, postoperative hospitalization times and cost of care.Study designRetrospective study.AnimalsDogs that underwent thoracic surgery in three veterinary hospitals between October 1, 2018 and October 1, 2020.MethodsAnesthesia and hospitalization records from 112 dogs were reviewed and 94 cases met inclusion criteria. Recorded data included signalment, disease etiology, pulmonary or extrapulmonary nature of disease, surgical procedure performed, episodes of severe intraoperative hypoxemia defined as a pulse oximetry reading (SpO2) <90% of 5 minutes or longer duration, survival to discharge, time from extubation to hospital discharge and total invoice cost for clinical visit. Dogs were divided into two groups, those that experienced severe hypoxemia (group A) and those in which SpO2 reading <90% was not observed throughout the procedure (group B).ResultsGroup A had a greater risk of mortality (odds ratio 10.6, 95% confidence interval 1.9–106.7; p = 0.002), prolonged hospitalization (median 62 hours versus 46 hours; p = 0.035) and more expensive cost of care (median US$10,287 versus $8506; p = 0.056) than group B. No significant difference was found for the type of surgical procedure or pulmonary versus extrapulmonary nature of disease.Conclusions and clinical relevanceSevere intraoperative hypoxemia was statistically associated with an increased risk of mortality and longer postoperative hospitalization times. Although not achieving statistical significance, there was a trend toward increased costs to the client for animals with intraoperative hypoxemia.  相似文献

OBJECTIVE: To identify causative organisms, treatment, outcome, and prognosis for dogs < 1 year old with community-acquired infectious pneumonia. DESIGN: Retrospective case series. ANIMALS: 65 dogs. PROCEDURES: Dogs were considered to have community-acquired infectious pneumonia if they had clinical signs of primary respiratory tract disease in conjunction with radiographic evidence of alveolar disease and positive results following bacterial culture of tracheal wash fluid. RESULTS: Most dogs were hypoxemic at the time of initial examination, with pulmonary function becoming worse during the first few days of hospitalization before improving; 57 (88%) dogs survived to discharge. Bordetella bronchiseptica was isolated from tracheal wash fluid from 32 (49%) dogs, and other organisms, predominantly gram-negative enteric bacteria, were isolated from the other 33 (51%). Dogs with Bordetella pneumonia were significantly younger (median, 14 vs 21 weeks), were significantly more likely to have been obtained from a pet store (19/31 vs 7/32), had been owned for a significantly shorter time prior to the onset of illness (median, 18 vs 90 days), had significantly higher PvCO2 values at initial examination (median, 48.7 vs 41.3 mm Hg), were significantly more likely to receive supplemental oxygen (25/32 vs 16/33), and had significantly longer hospitalization times (mean, 7.2 vs 4.9 days) than did dogs with pneumonia caused by any other organism. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that a type of community-acquired infectious pneumonia could be identified in dogs < 1 year old, with disease being more severe in dogs with Bordetella pneumonia than in dogs with pneumonia caused by other bacterial organisms.  相似文献

OBJECTIVE: To determine complications and neurologic outcomes associated with dexamethasone administration to dogs with surgically treated thoracolumbar intervertebral disk herniation, compared with dogs not receiving dexamethasone. DESIGN: Retrospective case series. ANIMALS: 161 dogs with surgically confirmed thoracolumbar disk herniation. PROCEDURES: Medical records from 2 hospitals were used to identify dogs that had received dexamethasone < 48 hours prior to admission (dexamethasone group dogs), dogs that received glucocorticoids other than dexamethasone < 48 hours prior to admission (other-glucocorticoid group dogs), and dogs that received no glucocorticoids (nontreatment group dogs). Signalment, neurologic injury grade, laboratory data, and complications were extracted from medical records. RESULTS: Dexamethasone group dogs were 3.4 times as likely to have a complication, compared with other-glucocorticoid or nontreatment group dogs. Dexamethasone group dogs were 11.4 times as likely to have a urinary tract infection and 3.5 times as likely to have diarrhea, compared with other-glucocorticoid or nontreatment group dogs. No differences in neurologic function at discharge or recheck evaluation were detected among groups. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that treatment with dexamethasone before surgery is associated with more adverse effects, compared with treatment with glucocorticoids other than dexamethasone or no treatment with glucocorticoids, in dogs with thoracolumbar intervertebral disk herniation. In this study population, no difference in outcome was found among groups. These findings suggest that the value of dexamethasone administration before surgery in dogs with thoracolumbar disk herniation should be reconsidered.  相似文献

Objective: To retrospectively evaluate the incidence of seizures in dogs presenting with a history of seizures that were treated with acepromazine (ACE) during hospitalization. Design: Retrospective study. Setting: Privately owned emergency and referral hospital. Animals: Thirty‐one client‐owned dogs. Interventions: Administration of ACE. Measurements and main results: The medical records from dogs with an acute or chronic seizure history that received ACE were reviewed. Factors evaluated included presenting complaint, seizure history, ACE dosage, duration of observation, seizure activity, and other medications used. Thirty‐one dogs qualified for the study: 20 males and 11 females. Age range was 3 months to 14.9 years. Presenting complaint was seizure in 28/31 dogs. There was a prior history of seizures in 22/31 dogs, and 15/22 were currently on antiseizure medication. ACE was given 1–5 times per dog. Mean ACE dose was 0.029 mg/kg IV (range: 0.008–0.057 mg/kg; n=46), 0.036 mg/kg IM (range: 0.017–0.059 mg/kg; n=14), 0.53 mg/kg PO (n=2). Twenty‐seven dogs did not seizure after administration of ACE within the observation period (mean: 16.4 hours, range: 0.25–66 hours). Twenty‐five dogs received antiseizure medication before ACE. Eight seizure episodes occurred in 4 dogs (all of whom presented for seizures) within 0.3–10 hours after ACE administration. Conclusions: There was no observed correlation between ACE administration in dogs with a seizure history and the recurrence of seizure activity during hospitalization. The time from ACE administration to seizure activity was greater than expected for measurable effects to be seen in 1 dog (10 hour). Further studies with a larger group and alternative ACE doses are needed to more thoroughly evaluate the safety of short‐term ACE use in dogs with a seizure history.  相似文献

The effect of systemic administration of glucocorticoids was evaluated on 3 populations of macrophages obtained from healthy dogs. Phagocytic and Fc-receptor activities were determined for mononuclear phagocytes from blood and pulmonary and peritoneal lavage fluids. Samples were collected from 12 dogs before treatment and again on the same dogs after glucocorticoid administration. Thirty or more days were allowed between treatment periods. Twelve hours after combined prednisolone sodium succinate and dexamethasone sodium phosphate administration, the percentage of phagocytosing cells decreased for blood monocytes and increased for pulmonary macrophages. The percentage of pulmonary macrophages positive for erythrocyte antibody-rosette formation (Fc-receptor activity) increased. After 7 days of oral administration of prednisone, the percentage of phagocytosing peritoneal macrophages increased, whereas the percentage of blood monocytes with Fc-receptor activity increased. Results indicate that significant (P less than 0.05) changes in macrophage function occur after systemic administration of the glucocorticoid doses used in this study. Also, the effect of systemic administration of glucocorticoids on mononuclear phagocytes varies, depending on the specific cell location.  相似文献

Objective – To determine whether the dose of antivenin administered is associated with a difference in survival of crotalid‐envenomated dogs. A secondary objective was to determine whether other covariables affect survival. Design – Retrospective study (1988–2006). Setting – Private referral center and university small animal teaching hospital. Animals – Two hundred and eighteen dogs with evidence of crotalid envenomation and treatment with equine‐derived antivenin. Interventions – Administration of antivenin. Measurements and Main Results – Patient signalment, physical and clinicopathologic data at time of presentation, treatments, complications of antivenin therapy, length and cost of hospitalization, and outcome were recorded. Confidence intervals were determined for the difference in median number of vials administered and for median dosage for patients that lived versus died. Penalized logistic regression was performed to evaluate the effect of other covariables on survival. The median age of affected dogs was 3 years (range 6 w–12 y) with a median weight of 25.7 kg (range 1.95–86.4 kg). The median number of antivenin vials administered was 1.0 (range 1.0–10.0). Acute and chronic reactions were reported in 7% (16/218) and 0.9% (2/218) of dogs, respectively. Nine of 218 dogs (4.1%) died. The median number of vials administered to the nonsurvivors and survivors were 2.0 (range 1–5 vials) and 1.0 (range 1–10 vials), respectively. The median number of vials received was significantly different in dogs that died versus those that lived (P<0.05). Increased heart rate (P=0.02) and petechiation (P=0.04) were associated with decreased likelihood of survival, while diphenhydramine (P=0.02) and fluoroquinolone (P=0.046) administration was associated with increased likelihood of survival. The median duration of hospitalization was 1.0 day (range 2 h–22 d). The median cost of hospitalization was US$1592.00 (range US$267.20–US$6738.00). Conclusion – The administration of more vials of antivenin is potentially associated with negative outcome; however, a causal relationship has not been established. Controlled, prospective studies are needed to optimize antivenin administration.  相似文献

BACKGROUND: Response to therapy in canine exocrine pancreatic insufficiency (EPI) varies considerably, making it difficult to determine prognosis for individual patients. HYPOTHESIS: Response to initial treatment (RIT) and survival are affected by signalment, clinical variables, and therapeutic regimen employed. ANIMALS: Client-owned dogs diagnosed with EPI between 1990 and 2002 were included in this study. METHODS: The study comprised a retrospective, questionnaire-based review. RESULTS: One hundred seventy-eight completed questionnaires were returned. RIT was good in 60% of treated dogs, partial in 17%, and poor in 23%. On univariate analysis, dogs that received antibiotics (P = .037) or had high serum folate concentration (P = .037) had a poorer RIT. On multivariate analysis, there were no strong predictors of good RIT. Nineteen percent of treated dogs were euthanized within 1 year, but overall median survival time for treated dogs was 1919 days. No clear benefit of changing to a fat-restricted diet could be demonstrated, but marked hypocobalaminemia (< 100 ng/L) was associated with shorter survival (P = .012). Use of uncoated pancreatic enzyme supplements, antibacterials, or H2 antagonists was not associated with longer survival. Breed, sex, age at diagnosis ( < or = 4 years or > 4 years), and clinical signs at diagnosis also made no difference. CONCLUSIONS AND CLINICAL IMPORTANCE: Long-term prognosis in canine EPI is favorable for dogs that survive the initial treatment period. Although there are few predictors of good RIT or long-term survival, severe cobalamin deficiency is associated with shorter survival. Therefore, parenteral cobalamin supplementation should be considered when hypocobalaminemia is documented.  相似文献

Objective – To describe the common clinical signs, laboratory abnormalities, treatment, and prognosis associated with acute aldicarb toxicosis in dogs. Design – Retrospective observational study from 2001 to 2009. Setting – Urban referral hospital. Animals – Fifteen client‐owned dogs. Interventions – None. Measurements and Main Results – The most common clinical signs associated with acute aldicarb toxicosis were vomiting, ptyalism, diarrhea, and tremors. Of the 15 dogs, 11 were admitted to the hospital for treatment, 2 were euthanized at presentation and 2 were discharged against medical advice following minimal treatment and lost to follow‐up. Laboratory abnormalities included lactic acidosis and hyperglycemia in 12 and 9 patients, respectively. Treatment of hospitalized dogs included induction of emesis with apomorphine (4 dogs), activated charcoal (5), IV fluids (11), atropine (7), methocarbamol (3), diazepam (1), pralidoxime (1) and diphenhydramine (1). Ten of 11 hospitalized dogs survived to discharge; 1 was euthanized following a respiratory arrest after 36 hours of hospitalization. One patient received mechanical ventilation and treatment for pneumonia before discharge from the hospital. The median duration of hospitalization was 22 hours (range 12–168 h). Conclusions – Acute aldicarb toxicosis carries a good prognosis for survival and hospital discharge with treatment. Supportive care should be considered for at least 18–24 hours to monitor for response to therapy and development of respiratory failure.  相似文献

Immune mediated hemolytic anemia (IMHA) in dogs is a severe disease with a high mortality rate. As human immunoglobulin (HIG) was reported to be beneficial for the treatment of IMHA in dogs we examined the influence of HIG on the course of the disease in our dogs with IMHA. Of 22 dogs with primary IMHA 9 dogs received in addition to routine immunosuppressive therapy HIG at a dose of 0.19 to 0.68 g/kg (median 0.35 g/kg), 13 dogs did not receive HIG (-HIG group). Both groups were similar in terms of age, weight, the presence of autoagglutination, spherocytosis, positive Coombs' test, icterus and pigmenturia. The lowest hematocrit measured during the disease was significantly lower in the +HIG group compared to the -HIG group and dogs in the +HIG group received significantly more transfusions than those of the -HIG group. This is an indication for more severe disease signs of the +HIG group dogs. Although mortality during hospitalization and the time from hospital admission to release or death was not significantly different between the two groups, we interpret this similar course of the IMHA despite more severe signs of the +HIG group dogs as a potential positive effect of the HIG therapy.  相似文献

Objective – To determine the utility of human intravenous immunoglobulin (hIVIG) for the initial treatment of canine immune-mediated hemolytic anemia (IMHA).
Design – Blinded, randomized, clinical trial.
Setting – Veterinary teaching hospital.
Animals – Twenty-eight, client-owned dogs with primary IMHA.
Interventions – At enrollment, after diagnosis of IMHA, dogs were randomly assigned to receive either hIVIG or placebo, in a blinded fashion. For the next 14 days, all dogs received glucocorticoids as the sole immunosuppressant agent. All dogs received low-molecular-weight heparin as an anticoagulant. D-dimer concentrations were evaluated at the beginning and end of the study protocol to monitor for thromboembolic complications.
Measurements and Main Results – Twenty-five of 28 dogs (89%) were discharged from the hospital. Thirteen of those received hIVIG and 12 received placebo. Twenty-four dogs (86%) were alive 14 days after enrollment, and of these 13 received hIVIG and 11 received placebo. D-dimer concentrations were elevated in 86% of all dogs at the time of diagnosis.
Conclusions – For initial treatment of dogs with IMHA, the addition of hIVIG to corticosteroid treatment did not improve initial response, nor did it shorten hospitalization.  相似文献

Treatment of Relapsed Canine Lymphoma With Doxorubicin and Dacarbazine   总被引：1，自引：1，他引：0  
Fifteen dogs with relapsed lymphoma were treated with doxorubicin and dacarbazine (ADIC) to reinduce remission. All the dogs' lymphomas had become resistant to prior therapy with doxorubicin alone. Five of the 15 dogs had a complete response to the first treatment with ADIC, and three had partial responses. Of the eight dogs receiving a second cycle, two had complete responses, and one had a partial response. One dog that received a third ADIC treatment no longer responded. The median survival time from the first ADIC treatment for all dogs was 45 days (range, 18-241 days). The five dogs having complete responses to the first ADIC treatment had a median survival time of 105 days (range, 45-241 days) after this treatment. Toxicity due to ADIC treatment was acceptable and did not exceed that seen when doxorubicin was given as a single agent. The treatment resulted in severe neutropenia in three dogs. One dog died due to neutropenic sepsis. Vomiting, diarrhea, and anorexia occurred, but were tolerable, resulting in hospitalization in only one instance. ADIC is apparently a useful chemotherapeutic combination to reinduce remission in some dogs with relapsed lymphoma.  相似文献

BACKGROUND: Hyperglycemia associated with critical illness in nondiabetic human patients is a common occurrence in the intensive care unit (ICU), with a reported incidence as high as 71%. HYPOTHESIS: Hyperglycemia in critically ill dogs increases the risk of morbidity and mortality. ANIMALS: Two hundred forty-five dogs hospitalized in the ICU over a 2-month period were evaluated. METHODS: Prospective observational study was conducted over a 2-month period. All dogs in the ICU had their highest daily blood glucose concentration recorded. All dogs with diabetes were excluded from the study. Hyperglycemia was defined as a blood glucose concentration >120 mg/dL. Dogs with hyperglycemia were monitored for persistence and resolution of hyperglycemia. RESULTS: During the study period, 245 dogs were evaluated, of which 38 (16%) were hyperglycemic. Twenty-six percent (10/ 38) developed hyperglycemia during hospitalization, whereas 74% (28/38) were hyperglycemic at presentation. Length of hospitalization (LOH) was shorter in dogs that presented with hyperglycemia compared with those that developed hyperglycemia during hospitalization (P = .001). Seventy-one percent (27/38) of dogs were discharged from the hospital, whereas the remaining 29% (11/38) died or were euthanatized. Nonsurvivors had significantly higher median glucose concentration (median, 176 mg/dL; range 122-310 mg/dL) than did survivors (median, 139 mg/dL; 121-191 mg/dL; P = .021). CONCLUSIONS AND CLINICAL IMPORTANCE: The incidence of hyperglycemia in this population of dogs was 16%. Dogs that developed hyperglycemia had longer LOH and nonsurvivors had more pronounced hyperglycemia than did survivors.  相似文献

Objective: To determine the frequency of postoperative pulmonary complications (PPCs) in dogs following laparotomy, characterize the nature of PPCs, and identify disease‐related risk factors for PPCs in dogs. Design: Retrospective clinical study. Setting: University‐affiliated small animal teaching hospital. Animals: One hundred and sixty‐two dogs without preoperative pulmonary pathology that underwent laparotomy surgery. Interventions: None. Measurements and main results: Cases were evaluated for factors including patient signalment, preexisting disease, primary and ancillary surgical procedure(s), development of postoperative pulmonary disease, characteristics of perioperative hospitalization and therapy, and survival. Twenty‐two percent of dogs in the study developed PPCs. PPCs included respiratory arrest (n=4), acute respiratory distress syndrome (ARDS) (n=3), pneumonia (n=8), hypoventilation (n=13), and transient hypoxemia (n=8). Dogs that developed PPCs had a significantly longer duration of oxygen therapy, longer duration of stay in intensive care unit (ICU), and decreased survival. Dogs with perioperative vomiting or regurgitation were more likely to develop PPCs. Animals that underwent exploratory laparotomy for biliary or septic peritonitis were also more likely to develop PPCs. Conclusions: PPCs occur in dogs following laparotomy and contribute significantly to the morbidity and mortality of these surgical patients. In this patient population, animals with vomiting, regurgitation, or peritonitis may be at a higher risk of developing PPCs. Animals with the identified risk factors should be monitored carefully postoperatively for development of pulmonary complications.  相似文献

This retrospective study in 39 dogs with incompletely resected oral melanoma examined the efficacy of hypofractionated radiation therapy and platinum-containing chemotherapy. All dogs were completely staged, with the majority of dogs classified as stage 1. Dogs received 6 weekly fractions of 6-gray (Gy) megavoltage irradiation with a cobalt-60 unit or a 4-MeV (megaelectron volts) linear accelerator. Dogs received cisplatin (10-30 mg/m2 IV) or carboplatin (90 mg/m2 IV) chemotherapy 60 minutes before radiation delivery. Durations of local control, metastasis-free survival time, and overall survival time were recorded. By the Kaplan-Meier method, 15% of the dogs had local recurrence within a median time of 139 days. Fifty-one percent of the dogs developed metastatic disease within a median time of 311 days (range, 24-2, 163 days). Median survival time for all 39 dogs was 363 days. The combined use of chemotherapy and radiation therapy in this protocol provided local control consistent with previous studies. Low-dose chemotherapy was used with the intent of enhancing radiation therapy for the local control of an incompletely excised tumor. Survival times were longer than previously reported for dogs with oral malignant melanoma. Additional studies are required to determine whether these results were due to the effects of chemotherapy on microscopic disease or the enhanced local control provided by chemoradiation therapy.  相似文献

This study describes the influence of 25% human serum albumin (HSA) supplementation on serum albumin level, total protein (TP), colloid osmotic pressure (COP), hospital stay, and survival in dogs with septic peritonitis. Records of 39 dogs with septic peritonitis were evaluated. In the HSA group, initial and post-transfusion TP, albumin, COP, and HSA dose were recorded. In the non-supplemented group, repeated values of TP, albumin, and COP were recorded over their hospitalization. Eighteen dogs survived (53.8% mortality). Repeat albumin values were higher in survivors (mean 23.9 g/L) and elevated repeat albumin values were associated with HSA supplementation. Repeat albumin and TP were higher in the HSA supplemented group (mean 24 g/L and 51.9 g/L, respectively) and their COP increased by 5.8 mmHg. Length of hospitalization was not affected. Twenty-five percent HSA increases albumin, TP, and COP in canine patients with septic peritonitis. Higher postoperative albumin levels are associated with survival.  相似文献

The purpose of this retrospective study was to evaluate the efficacy and toxicity of the MOPP chemotherapy protocol (mechlorethamine, vincristine, procarbazine, and prednisone) as a rescue regimen in dogs with lymphoma. One hundred seventeen dogs that had resistance to previously administered chemotherapy were evaluated. Before treatment with MOPP, all dogs received a median of 6 chemotherapy drugs for a median duration of 213 days. Thirty-one percent (36 of 117) had a complete response (CR) to MOPP for a median of 63 days, and 34% (40 of 117) had a partial response (PR) for a median of 47 days. Sixteen percent (19 of 117) had stable disease (SD) for a median of 33 days. Predictors for response to MOPP were not identified. Gastrointestinal (GI) toxicity occurred in 28% (33 of 117) of the dogs, and 13% (15 dogs) required hospitalization. Five dogs developed septicemia, and 2 died as a result. MOPP was an effective treatment for dogs with resistant lymphoma and was well tolerated by the majority of affected dogs.  相似文献
