Postanesthetic Pulmonary Edema In an Arab Stallion     

Thomas K. Day DVM  MS    Susan Holcombe VMD  William W. Muir II  DVM  PhD 《Journal of Veterinary Emergency and Critical Care》1993,3(2):90-95

A six-year-old arabian stallion was admitted to The Ohio State University Veterinary Hospital for evaluation and repair of a comminuted fracture of the second phalanx. The horse developed impaired arterial oxygenation during surgey and pulmonary edema post-operatively. We postulate that impaired arterial oxygenation resulted from atelectasis of the dependent lung during annesthesia, and the pulmonary edema occurred following re-expansion of the atelectatic of the initiating cause of the edema, removal of excess lung water from the alveoli, and restoration of normal arterial oxygenation. The horse was fully recovered within 12 hours of initiation of clinical signs of respiratory compromise. The horse was fully recovered within 12 hours of initiation of clinical signs of respiratory compromise. This report describes re-expansion pulmonary edema due to reperfusion injury in a horse, treatment of the condition, and a possible explanation of the pathogenesis of this pulmonary pathology.  相似文献

Evaluation of the RZWQM-CERES-Maize hybrid model for maize production     

L. Ma  G. Hoogenboom  L.R. Ahuja  J.C. Ascough II  S.A. Saseendran 《Agricultural Systems》2006

The root zone water quality model (RZWQM) was developed primarily for water quality research with a generic plant growth module primarily serving as a sink for plant nitrogen and water uptake. In this study, we coupled the CERES-Maize Version 3.5 crop growth model with RZWQM to provide RZWQM users with the option for selecting a more comprehensive plant growth model. In the hybrid model, RZWQM supplied CERES with daily soil water and nitrogen contents, soil temperature, and potential evapotranspiration, in addition to daily weather data. CERES-Maize supplied RZWQM with daily water and nitrogen uptake, and other plant growth variables (e.g., root distribution and leaf area index). The RZWQM-CERES hybrid model was evaluated with two well-documented experimental datasets distributed with DSSAT (Decision Support System for Agrotechnology Transfer) Version 3.5, which had various nitrogen and irrigation treatments. Simulation results were compared to the original DSSAT-CERES-Maize model. Both models used the same plant cultivar coefficients and the same soil parameters as distributed with DSSAT Version 3.5. The hybrid model provided similar maize prediction in terms of yield, biomass and leaf area index, as the DSSAT-CERES model when the same soil and crop parameters were used. No overall differences were found between the two models based on the paired t test, suggesting successful coupling of the two models. The hybrid model offers RZWQM users access to a rigorous new plant growth model and provides CERES-Maize users with a tool to address soil and water quality issues under different cropping systems.  相似文献   

Effect of metoclopramide on gastro-esophageal reflux in anesthetized dogs     

DV Wilson  AT Evans  W. Mauer 《Veterinary anaesthesia and analgesia》2005,32(4):4-4

Administration of morphine before anesthesia leads to gastro-esophageal reflux (GER) in over 50% of dogs during the subsequent anesthetic. This GER is clinically silent but can lead to aspiration pneumonitis, esophagitis and esophageal stricture. In this prospective clinical study we aimed to determine the effect of metoclopramide on gastro-esophageal reflux (GER) in dogs undergoing elective orthopedic surgery. Dogs were admitted to the study if they were healthy, and had no history of vomiting or dysphagia. Dogs were fasted for an average of 18.2 ± 4.3 (mean ± SD) hours prior to induction of anesthesia. Anesthesia in all dogs included acepromazine, morphine, thiopental and isoflurane in oxygen. By random allocation, half the dogs received metoclopramide (M) as an IV bolus (0.4 mg kg^–1) and then infusion (0.3 mg kg^–1hour^–1), the others received equivalent volumes of saline (S). To measure esophageal pH a sensor-tipped catheter was placed with the tip 5–7 cm cranial to the lower esophageal sphincter, and connected to a computer for continual data collection. The pH of any fluid running from the mouth or nose was measured. Gastro-esophageal reflux was defined as a decrease in esophageal pH below 4 or an increase above 7.5. Fisher's Exact test was used to test significance of differences in incidence between groups. Separate multivariable logistic regression models were created for each outcome to assess the effects of risk factors on outcome. There were seven cases of GER in 16 dogs receiving M and 8/14 in those receiving S. There were no significant differences between M and S treated dogs in age, weight, duration of anesthesia and fasting, thiopental dose or incidence of vomiting. The administration of metoclopramide at this dose did not significantly reduce the incidence of GER in these anesthetized dogs.  相似文献   

Drug residues in food animals. III. Plasma and tissue kinetics of potassium penicillin G in young cross-bred swine     

H. DWIGHT MERCER  RICHARD H. TESKE  PATRICIA E. LONG  DAVID II. SIIOWALTER  HENRY H. BRYANT 《Journal of veterinary pharmacology and therapeutics》1978,1(4):253-266

Twenty-two young cross-bred swine were treated either intravenously or orally with potassium penicillin G. The pharmacokinetics of penicillin G were determined in plasma and tissues. The plasma half-life of penicillin G in swine was found to be 19.45±1.69 min, and the distribution and elimination kinetics were found to fit a classical two-compartment model. The volume of distribution was found to be 0.53±0.12 1/kg, and the body clearance was found to be 19.06±5.06 ml/min/kg which exceeded the effective renal plasma flow of 16.50±2.73 ml/min/kg, suggesting that the drug was eliminated both by tubular excretion and glomerular filtration. The elimination rate constants (Beta) for the major organs were as follows: muscle, 0.00343 min^-1; lung, 0.0310 min^-1; fat, 0.0394 min^-1; and kidney, 0.0213 min^-1, which compared favorably with the elimination rate constant found in plasma (0.0320 min^-1). These values were found to be significantly similar at the level of P < 0.005 in muscle, spleen and fat, and at a level of P < 0.025 in lung tissue. The data indicates that blood plasma would be a satisfactory body fluid for estimating this drug in tissue.  相似文献

Methicillin resistant Staphylococcus aureus (MRSA) infection in a dog in the Netherlands     

van Duijkeren E  Box AT  Mulder J  Wannet WJ  Fluit AC  Houwers DJ 《Tijdschrift voor diergeneeskunde》2003,128(10):314-315

In the Netherlands, methicillin resistant Staphylococcus aureus (MRSA) are regularly isolated from humans. We present the first isolation of MRSA from animal origin in the Netherlands. A coagulase positive staphylococcus was cultured from an infected wound in a Dutch dog that recently underwent surgery abroad. The staphylococcus was resistant to methicillin, ampicillin, amoxycillin + clavulanic acid, cephalexin, erythromycin, lincomycin, tetracycline, gentamicin and enrofloxacin. It was identified as S. aureus by fermentation of mannitol and Martineau-PCR. The presence of mecA was confirmed by PCR.  相似文献   

The Value of a Net‐Cage as a Fish Aggregating Device in Southern California     

Christopher T. Oakes  Daniel J. Pondella II 《Journal of the World Aquaculture Society》2009,40(1):1-21

There is an urgent need for primary data that can be used to quantify the value of marine aquaculture facilities that also describe influences on the surrounding natural ecosystem and its wild fish communities. Divers completed 360 transect replicates below a net‐cage and at nearby and distant rocky reefs off Catalina Island, California, estimating the species abundance and size class of all conspicuous fishes in the water column. We observed 10,234 fishes aggregating below the net‐cage with a mean annual density of 142 (SE ± 30) per 100 m² and diversity H′ 2.29. At the adjacent reference reef, we counted 8452 fishes with a mean annual density of 117 (SE ± 20) and H′ 1.45 and at Reference Reef 2, located 500 m away, there were 8958 fishes with a density of 124 (SE ± 20) and H′ 1.13. The total density of fishes was the same between the study sites (ANOVA; P = 0.24); however, the spatial density of fishes in the water column was different between the net‐cage and reference reefs. Additionally, the density of juvenile fish was significantly lower at the net‐cage (ANOVA; P = 0.02), while the density of subadult and adult fishes was higher (ANOVA; P = 0.03). Feeding guild analysis ranked the net‐cage highest (3507), while Reference Reef 1 (2149), and Reference Reef 2 (2241), had lower values, a relationship often found between artificial and natural reefs. This suggests the importance of available trophic resources to the adult population of wild fishes, and has implications in the artificial reef attraction–production debate. The results of this study not only reproduce a pattern of fish attraction to net‐cages in the marine environment reported in previous studies but also demonstrate a relative habitat value compared in both time and space, of the fish community at a net‐cage compared with vibrant kelp bed communities.  相似文献
