Objective – To review the use of IV lipid emulsion (ILE) for the treatment of toxicities related to fat‐soluble agents; evaluate current human and veterinary literature; and to provide proposed guidelines for the use of this emerging therapy in veterinary medicine and toxicology. Data Sources – Human and veterinary medical literature. Human Data Synthesis – Human data are composed mostly of case reports describing the response to treatment with ILE as variant from mild improvement to complete resolution of clinical signs, which is suspected to be due to the variability of lipid solubility of the drugs. The use of ILE therapy has been advocated as an antidote in cases of local anesthetic and other lipophilic drug toxicoses, particularly in the face of cardiopulmonary arrest and unsuccessful cardiopulmonary cerebral resuscitation. Veterinary Data Synthesis – The use of ILE therapy in veterinary medicine has recently been advocated by animal poison control centers for toxicoses associated with fat‐soluble agents, but there are only few clinical reports documenting successful use of this therapy. Evidence for the use of ILE in both human and veterinary medicine is composed primarily from experimental animal data. Conclusions – The use of ILE appears to be a safe therapy for the poisoned animal patient, but is warranted only with certain toxicoses. Adverse events associated with ILE in veterinary medicine are rare and anecdotal. Standard resuscitation protocols should be exhausted before considering this therapy and the potential side effects should be evaluated before administration of ILE as a potential antidote in cases of lipophilic drug toxicoses. Further research is waranted. 相似文献

ObjectiveTo review the available literature concerning the physiologic and pharmacologic alterations induced by obesity in canine and feline patients and their relevance to perioperative care.Study designLiterature review.DatabasesPubmed, CAB, Web of Science.ConclusionsObesity of cats and dogs is a chronic inflammatory condition that is increasingly prevalent. Similar to the situation in humans, small animal obesity may be associated with changes in endocrine, respiratory, and cardiovascular function. In addition, alteration of body composition in obesity can affect pharmacokinetic variables. Modifications in perioperative care may need to be made for obese dogs and cats, including attention to respiratory and cardiovascular supportive care and drug dose adjustments. 相似文献

Objective – To characterize the provision of CPCR by small animal veterinarians in clinical practice and to assess how this practice varies among different levels of expertise. Design – Internet‐based survey. Setting – Academia, referral practice, and general practice. Subjects – Six hundred and two small animal veterinarians in clinical practice. Respondents were grouped a priori according to level of expertise: board‐certified (ACVECC, ACVA, ECVAA) specialists; general practitioners in emergency clinics; general practitioners in general practice (GPG). Interventions – Email invitations to the online questionnaire were disseminated via a veterinary internet platform and mailing list server discussion groups. Questions explored respondent characteristics, CPCR preparedness, infrastructural and personnel resources, and techniques of basic and advanced life support. Main Results – In this group of practitioners, the majority (65%) were in general practice. GPG were more likely to perform CPCR <5 times per year and to have 3 or fewer members on their resuscitation team. Most practitioners have a crash cart and drug‐dosing chart available. GPG were less likely to obtain resuscitation codes on their patients, and less likely to use end‐tidal carbon dioxide monitoring or defibrillation. Intubation, oxygen supplementation, vascular access, and external thoracic compressions were widely used, however, GPG were more likely to use lower chest compression rates. Drugs used for CPCR differed among the groups with GPG more likely to use doxapram and glucocorticoids. Conclusions – CPCR is heterogeneously performed in small animal veterinary medicine; differences exist, both among and within different types of veterinarians with varying levels of expertise, in respect to available infrastructure, personnel and CPCR techniques used. 相似文献

Several new multi-purpose non-rebreathing anaesthetic systems have been developed for human anaesthesia. This study evaluated a New Zealand designed non-rebreathing circuit, the Palmerston Valve, in anaesthetised spontaneously breathing dogs and compared it to the widely used Lack coaxial circuit. Arterial blood gas measurements 60 minutes after induction demonstrated comparable slight increases in PaCO2 in nearly all dogs maintained on the Palmerston Valve and Lack coaxial circuit with halothane and oxygen mixtures, and a fresh gas flow rate of 70 ml/kg/min. Results suggest the Palmerston Valve is at least as efficient as the Lack coaxial circuit, while offering in the same unit the potential for economical controlled ventilation. 相似文献

Objective – To report the prevalence of hyperglycemia in cats admitted to a veterinary hospital and to determine if hyperglycemic cats had increased morbidity and mortality when compared with normoglycemic cats.
Design – Retrospective clinical study.
Setting – Community-based referral hospital.
Animals – Nondiabetic cats admitted to the hospital.
Interventions – None.
Measurements and Main Results – The medical records of nondiabetic cats admitted to the hospital over a 1-year period were reviewed. There were 182 cats that met the criteria for inclusion in the study. Information obtained included signalment, length of hospitalization, initial and highest blood glucose measurement, diagnosis, treatment, and final disposition. Sixty-three percent of cats (116/182) were hyperglycemic at the time of presentation. Total incidence of hyperglycemia at any point during hospitalization was 64% (118/182). No association was found between hyperglycemia either initially or at any point during the hospitalization and mortality. However, a significant association was documented between the presence of hyperglycemia and increased length of hospitalization (LOH) ( P =0.04). The duration of LOH was also significantly associated with the degree of hyperglycemia ( P =0.01). A number of different disease processes were represented in the study population. However, the number of cats in each disease category was small and no association could be found between any of them and blood glucose affecting mortality and morbidity.
Conclusion – The prevalence of hyperglycemia in feline patients admitted to a primary referral hospital was 64%. Cats with hyperglycemia had a longer LOH when compared with normoglycemic cats; however, presence of hyperglycemia did not impact mortality in this population of cats. 相似文献

Engineering controls (EC, facility and equipment barriers between hazards and people) are used to avoid exposure to chemotherapy drugs. In this study, American College of Veterinary Internal Medicine board‐certified veterinary oncologists were surveyed about their use of containment primary EC (C‐PEC) and supplemental EC (closed system transfer devices, CSTD). The survey was completed by 148 (38%) of practicing diplomates. All used EC. Both C‐PEC and CSTD were used at 92% of hospitals; however, US Pharmacopoeial Convention Chapter <800> (USP <800>) standards were met at only 19% of hospitals and oncologists did not know the type of C‐PEC at 18% of hospitals. Next, surface contamination and EC use were assessed with environmental surveillance for carboplatin, cyclophosphamide, doxorubicin, and vincristine in 20 veterinary specialty hospitals using a commercially available kit. No contamination with carboplatin, doxorubicin, or vincristine was detected, however, there was contamination with cyclophosphamide at 4 hospitals. Based on this study, most veterinary oncologists use C‐PEC and CSTD, but few meet USP <800> standards. Current measures appear effective for preventing contamination with IV drugs, but additional measures are needed for oral drugs. 相似文献

OBJECTIVE: To ascertain anaesthetic practices currently for dogs and cats in Australia. METHODS: A questionnaire was distributed to 4,800 veterinarians throughout Australia, seeking data on numbers of dogs and cats anaesthetised per week; drug preferences for anaesthetic premedication, induction and maintenance; use of tracheal intubation, supplemental nitrous oxide and anaesthetic antagonists; and types of vaporisers, breathing systems and anaesthetic monitoring devices used or available. Additional questions concerned proportions of different animal types seen in the practice, and the respondent's university and year of graduation. RESULTS: The response rate was 19%; 95% of respondents graduated from Australian universities, about half since 1985. Most responses (79%) came from mainly small animal practices. On average 16 dogs and 12 cats were anaesthetised each week. Premedication was used more often in dogs than cats, with acepromazine and atropine most favoured in both species. For anaesthetic induction, thiopentone was most preferred in dogs and alphaxalone/alphadolone in cats. Inhaled agents, especially halothane, were preferred for maintenance in both species. Most respondents usually employed tracheal intubation when using inhalational anaesthetic maintenance, but intubation rates were lower during injectable anaesthetic maintenance and a minority of respondents provided supplemental O2. Nitrous oxide was administered regularly by 13% of respondents. The agents most frequently used to speed recovery from anaesthesia were doxapram and yohimbine. The most widely used vaporisers were the Fluotec Mark III and the Stephens machine. Most (95%) respondents used a rebreathing circuit for large dogs and a non-rebreathing system was used for small dogs by 68% of respondents. Most respondents (93%) indicated some form of aid was available to monitor general anaesthesia: the three most mentioned were an apnoea alarm, oesophageal stethoscope and electrocardiogram. CONCLUSION: Diverse approaches were evident, but there appeared to be less variation in anaesthetising dogs: premedication was more frequent and less varied in type, while thiobarbituates dominated for induction and inhalants for maintenance. Injectable maintenance techniques had substantial use in cats, but little in dogs. Evident disparity between vaporisers available and circuits used suggested either confusion in terminology or incorrect use of some vaporisers in-circuit. While most respondents used monitoring equipment or a dedicated observer to invigilate anaesthesia, the common reliance on apnoea alarms is of concern, because of unproven reliability and accuracy. 相似文献

Objective – To compare blood pressure measurements obtained via ultrasonic Doppler flow monitor (DOP) and 2 oscillometric noninvasive blood pressure monitors (CAR and PAS) to invasive blood pressure (IBP) in hospitalized, conscious dogs with a range of blood pressures. Design – Prospective clinical study. Setting – University teaching hospital. Animals – Eleven client‐owned dogs aged between 4 months and 11.5 years (median 6 y), and weighing between 5.8 and 37.5 kg (median 30.2 kg). Interventions – Blood pressure measurement. Measurements and Main Results – Three consecutive measurements of systolic, diastolic, and mean arterial pressure (MAP) were recorded for each of the 3 indirect devices (only systolic for DOP), along with concurrent IBP measurements. The data were categorized into 3 groups: hypotensive (direct MAP<80 mm Hg), normotensive (80 mm Hg≤direct MAP≥100 mm Hg), and hypertensive (direct MAP>100 mm Hg). Each indirect method was compared with the corresponding direct arterial pressure using the Bland‐Altman method. Within the hypotensive group, each indirect method overestimated the corresponding IBP. Within the normotensive group all indirect systolic measurements and the PAS diastolic measurements underestimated the corresponding IBP. The remaining indirect measurements overestimated the corresponding IBP. Within the hypertensive group, DOP and CAR systolic measurements underestimated the corresponding IBP, and the remaining indirect measurements overestimated the corresponding IBP. In hypertensive dogs oscillometric systolic measurements were more accurate than MAP. In hypotensive dogs MAP measurements were more accurate than systolic measurements. All indirect measurements were most accurate in hypertensive dogs. Conclusions – The noninvasive blood pressure monitors in our study did not meet the validation standards set in human medicine. However, CAR diastolic and MAP measurements within the normotensive group, CAR MAP measurements within the hypertensive group, and PAS diastolic measurements in all groups were close to these standards. All indirect measurements showed greater bias during hypotension. Precision was poorer for all indirect systolic measurements than for MAP. 相似文献

Normal dog semen ranges in volume from 1 to 30 mL per ejaculate and contains 300 million to 2 billion sperm, of which more than 70% are progressively motile and morphologically normal. Dog semen should contain fewer than 10,000 bacteria per mL; higher numbers are indication of an infection of the male reproductive tract and usually are associated with cytologic evidence of inflammation (neutrophils in semen sediment) and with decreased progressive motility and decreased numbers of morphologically normal sperm. Measurement of pH of seminal plasma of dogs with infection of the reproductive tract may provide information on determining the choice of antibiotic. Measurement of seminal plasma alkaline phosphatase in azoospermic dogs is an indicator of tubular patency to the level of the epididymides. 相似文献
