Pulmonic valvuloplasty is a well-established method for the treatment of valvular pulmonic stenosis in people and dogs. In dogs, pulmonic valvuloplasty has been restricted to a single balloon; however, the simultaneous use of two balloons is common in pediatric cardiology. The use of two balloons provides an alternative to the use of a single large balloon in small dogs with a pulmonic anulus size that requires a large dilation catheter and large diameter introducer. Moreover, double balloon valvuloplasty permits dilation in large dogs with large pulmonic anulus sizes for which standard dilation catheters are not available. This report outlines the materials required, describes the technique, gives the advantages and disadvantages encountered when performing percutaneous double balloon valvuloplasty and provides some ‘tips’ for a successful outcome. 相似文献

The records of all dogs and cats receiving total parenteral nutrition (TPN) over a 43-month period were examined retrospectively. Dextrose, amino acids, lipids, electrolytes, and vitamins were administered by central venous catheter according to published nutrient recommendations; 72 dogs and 12 cats were studied, accounting for 380 patient days of TPN. Duration of TPN administration was 1–14 days with a mean of 4.5 days. Most animals required TPN because of gastrointestinal dysfunction, and more than half of them gained weight during TPN administration. Mechanical complications were frequent. Metabolic complications, especially lipid and glucose intolerance, were also commonly seen. Septic complications were the least frequently encountered, but resulted in patient morbidity and may have contributed to mortality. Most animals receiving TPN were returned to enteral nutrition and discharged. For critically ill animals unable to tolerate enteral alimentation, TPN can be supportive therapy in the treatment of the primary disease. 相似文献

Background
Myocardial disease in camelids is poorly characterized. Nutritional (selenium deficiency) and toxic (ionophore toxicity) myocardial disease have been reported in camelids. Diagnosis and management of these and other myocardial diseases might be enhanced by evaluating cardiac troponin I (cTnI) concentrations. No information about cTnI reference intervals in camelids is currently available.Hypothesis/Objectives
(A) To determine cTnI concentrations obtained using a point of care i-STAT®1 analyzer (Heska Corporation) in healthy alpacas; (B) to compare alpaca cTnI concentrations between heparinized whole blood and plasma samples and between 2 different storage conditions (4 °C for 24 h or −80 °C for 30 days); (C) to examine assay reproducibility using the i-STAT®1.Animals, materials and methods
23 healthy alpacas were evaluated. Blood and plasma samples were analyzed by the i-STAT®1 within 1 h of collection. Aliquots of plasma were stored at either 4 °C for 24 h or −80 °C for 30 days, and then analyzed. Assay reproducibility was determined by comparing 2 plasma or whole blood cTnI concentrations measured on the same sample over a 10 min period.Results
Analyzer-specific plasma cTnI concentrations in clinically normal alpacas had a median of <0.02 ng/mL (range: <0.02 ng/mL to 0.07 ng/mL). Plasma and whole blood concentrations showed good agreement. Storage did not affect cTnI concentrations (p > 0.75). Plasma cTnI concentrations had coefficient of repeatability of 0.02 ng/mL.Conclusions
The i-STAT®1 can measure cTnI in alpacas on both plasma and whole blood and provides similar values for both samples. Storage at 4 °C for 24 h or −80 °C for 30 days does not affect estimates of plasma cTnI. Evaluation of cTnI might be of value in assessing cardiac disease in this species. 相似文献10.

Objective—To determine the antinociceptive effects of oxymorphone, butorphanol, and acepromazine individually and in combination to a noxious visceral stimulus in cats. Study Design—Randomized, blinded controlled study. Animals—Eight healthy mixed-breed cats (four male, four female) weighing 4.4 ± 1.2 kg and aged 1 to 2 years old. Methods—A silastic balloon catheter was inserted per rectum and inflated at various pressures. Physiological parameters (respiratory rate, pulse rate, and blood pressure) were also recorded. Subjects were administered individual and combined intravenous (IV) doses of 0.025, 0.05, 0.10, and 0.20 mg/kg oxymorphone and 0.025, 0.05, 0.10, and 0.20 mg/kg butorphanol. A further study of various ratios of butorphanol and oxymorphone (3:1, 2:1, 1:1, 1:2, and 1:3), at a combined equivalent dose of 0.1 mg/kg, was performed in four cats per dose combination. In a separate study, four cats were administered combined IV doses of 0.05 mg/kg each of oxymorphone and butorphanol or 0.05 mg/kg each of oxymorphone, butorphanol, and acepromazine. Results—Combined doses of 0.05 and 0.10 mg/kg of oxymorphone and butorphanol showed mainly additive with some synergistic antinociceptive interactions and the combined dose of 0.2 mg/kg of each agent demonstrated additional antinociceptive effects, P < .05. Additional studies showed that various ratios of the two agents at a total combined dose of 0.10 mg/kg IV did not produce levels of antinociception that were significantly different from each other, P > .05. Acepromazine (ACE) significantly increased the magnitude of antinociception at 15 minutes when administered in combination with oxymorphone and butorphanol, P < .05. Also, physiological variables were unaffected by these drug combinations. Conclusions—Low doses of oxymorphone and butorphanol in combination can produce greater levels of antinociception than when used individually. ACE, in conjunction with oxymorphone and butorphanol, produced even greater levels of antinociception than the two-opioid drug combination. Clinical Relevance—Oxymorphone, butorphanol, and ACE can be used in combination to produce additive or synergistic effects without adverse effects in cats. These data suggest that ACE and butorphanol at low doses given as preanesthetic medication followed by a mu opioid (eg, oxymorphone) after surgery at low doses may provide an effective method of pain management in the cat. 相似文献
