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   

A comparison of the efficacy and cardiorespiratory effects of four medetomidine-based anaesthetic protocols in the red fox (Vulpes vulpes)

ObjectiveTo evaluate the anaesthetic and cardiorespiratory effects of four anaesthetic protocols in red foxes (Vulpes vulpes).Study designProspective, blinded and randomized complete block design.AnimalsTen adult captive red foxes.MethodsFoxes were anaesthetized by intramuscular (IM) injection using four protocols in random order: medetomidine 40 μg kg^?1, midazolam 0.3 mg kg^?1 and butorphanol 0.1 mg kg^?1 (MMiB), medetomidine 40 μg kg^?1 and ketamine 4 mg kg^?1 (MK40/4), medetomidine 60 μg kg^?1 and ketamine 4 mg kg^?1 (MK60/4), medetomidine 40 μg kg^?1 and tiletamine/zolazepam 2 mg kg^?1 (MTZ). Time to lateral recumbency, induction time and time to recovery following IM administration of atipamezole 0.2 mg kg^?1 were recorded. Heart rate (HR), respiratory rate (_fR) and rhythm, blood pressure, rectal temperature, end-tidal CO₂ tension (Pe′Co₂), functional oxygen saturation and presence/absence of interdigital, palpebral and ear reflexes were recorded every 10 minutes, and following administration of atipamezole. Data were analysed using two-way repeated-measures anova with Bonferroni post tests; p < 0.05 was considered significant.ResultsAll protocols produced profound sedation with good muscle relaxation. Only the MMiB protocol diverged significantly from the others. Induction of anaesthesia and recovery time following atipamezole were significantly longer, and f_R and initial HR significantly lower with MMiB than with the other protocols. With all protocols, mean arterial blood pressure (MAP) was initially relatively high (140–156 mmHg), and decreased significantly over time. With all protocols, the administration of atipamezole resulted in a rapid, significant decrease in MAP and an increase in HR.Conclusions and clinical relevanceAll four protocols provided anaesthetic conditions suitable for minor procedures and allowed endotracheal intubation. The cyclohexanone protocols provided quicker and more reliable inductions and recoveries than the MMiB protocol.  相似文献   

Adenosquamous Carcinoma of the Trachea in a Domestic Ferret (Mustela putorius furo)     

Olivia A. Petritz  Natalie Antinoff  Catherine Pfent  Wayne Corapi  Roy R. Pool  Michelle Fabiani  Sue Chen 《Journal of Exotic Pet Medicine》2013,22(3):287-292

A 4-year-old, castrated, male domestic ferret (Mustela putorius furo) was evaluated for a possible upper respiratory tract infection and wheezing for approximately 3 weeks. Supportive care for a suspected upper respiratory tract infection was initiated; however, the patient became progressively more dyspneic over the next 48 hours. A possible tracheal mass was identified upon thoracic radiographic imaging of the ferret. Tracheoscopy and a computed tomography scan of the neck and thorax confirmed the presence of a tracheal mass approximately 3 cm from the larynx obstructing 80% of the tracheal lumen. Rather than pursuing surgical resection, the owners elected humane euthanasia. An adenosquamous carcinoma of the trachea was diagnosed after histologic analysis. This tumor type has been diagnosed in the lungs of ferrets that were experimentally exposed to carcinogens found in cigarette smoke; however, there are no previous reports of this or any other tumor type associated with the ferret trachea. A tracheal mass causing a partial upper airway obstruction should be considered within the differential disease diagnosis list when a ferret is presented with dyspnea.  相似文献   

Are media messages to consume more under‐utilized seafood species reliable?     

Anna K Farmery  Ingrid E van Putten  Michelle Phillipov  Alistair McIlgorm 《Fish and Fisheries》2020,21(4):844-855

Consumers are being encouraged to choose sustainable seafood. In particular, eating less‐popular, under‐utilized species is promoted as a more sustainable seafood choice. This message is advocated in the media by a range of different organizations and individuals; however, evidence of greater seafood sustainability as a result of these messages is lacking. We examine current media messaging around sustainable seafood, focussing on the messages to eat more under‐utilized species, in an Australian and international context. We identify six different intended outcomes of these messages, including that eating more under‐utilized species will take pressure off heavily fished stocks, and explore the conditions under which the perceived outcomes would be realized. We use an economic lens and discuss the effect of certain aspects of consumer demand and seafood product substitutability. We propose that in order to take pressure off overfished stocks, the message to consume more under‐utilized species would need to be accompanied by messages to limit or eat less seafood. In addition, the benefits of eating more under‐utilized species as currently promoted are not always achievable and that the outcomes of some messages, if realized, could lead to overfishing of unregulated stocks and a reduction in overall fish supply. While there are many potentially positive social, economic and environmental outcomes of consuming currently under‐utilized species, media messages should encourage consumers to buy a range of seafood, including under‐utilized species, which can be traced back to a well‐managed fishery, rather than promoting under‐utilized species per se.  相似文献   

Methicillin‐Resistant Staphylococcus aureus Colonization in Personnel Attending a Veterinary Surgery Conference     

LEE C. BURSTINER DVM  MEREDITH FAIRES DVM  MSc  J. SCOTT WEESE DVM DVSc  Diplomate ACVIM 《Veterinary surgery : VS》2010,39(2):150-157

Objective— To evaluate the prevalence of, and risk factors for, methicillin‐resistant Staphylococcus aureus (MRSA) colonization in veterinary personnel. Study Design— Cross‐sectional study. Sample Population— Conference attendees (n=341) at the 2008 American College of Veterinary Surgeons Symposium in San Diego California. Methods— Nasal swabs were collected and tested using selective culture for MRSA. Isolates were typed and risk factors were evaluated using questionnaire data. Results— 17.3% of subjects (17% veterinarians and 18% technicians) were MRSA positive. Colonized individuals originated from 5 different countries, predominantly the United States and Canada. Contact with small ruminants in the preceding 30 days (odds ratio [OR] 2.2), living with a person diagnosed with MRSA in the preceding year (OR 19.8) and working in a clinic where there is a specific person in charge of the infection control program (OR 2.2) were associated with colonization using multivariable analysis. Conclusion— The high rate of colonization identified here provides more evidence that MRSA exposure is likely an occupational risk for veterinary personnel. The equal rates in small animal and large animal personnel were surprising and contradict earlier studies indicating greater rates among equine personnel. The association of MRSA and small ruminant contact has not been reported previously. Clinical Relevance— MRSA is an important emerging pathogen in veterinary medicine and is a concern for both patients and veterinary personnel. The high colonization rate indicates the need to understand and control the spread of MRSA in veterinary clinics.  相似文献
