通过对比中国兽药典、中国药典、美国药典和欧洲药典中相对密度测定法,了解四部药典的异同点,旨为中国兽药典引入新方法提供参考。分别对四部药典的收载情况、测定法原理、应用范围等进行比较和讨论。四部药典收载的测定法略有差异,中国兽药典收载的测定法在测定黏稠液体时具有一定局限性。建议中国兽药典在充分调研基础上,引入振荡型密度计测定法。 相似文献

OBJECTIVE: To evaluate selected hemodynamic, blood gas, and biochemical responses to mild to moderate acute blood loss in standing, awake horses. DESIGN: Prospective study. ANIMALS: 7 healthy mares. PROCEDURES: Each horse was restrained in standing stocks, and its head was maintained in a neutral position; sedatives and tranquilizers were not administered. During a 1-hour period, blood was collected into collection bags by use of a suction pump. The rate of blood collection was approximately 16 mL/kg/h (7.3 mL/lb/h). Thirty minutes after blood collection, the blood was readministered at the same rate. Central venous pressure (CVP), central venous blood gas, blood lactate concentration, and heart rate were measured at baseline (after placement of catheters), after removal of blood, and after readministration of blood. RESULTS: In response to blood loss, CVP decreased and blood lactate concentration increased significantly, compared with baseline values; heart rate and results of central venous blood gas analysis did not change significantly. After readministration of blood, CVP returned to baseline value and blood lactate concentration approached baseline value. CONCLUSIONS AND CLINICAL RELEVANCE: Changes in CVP and blood lactate concentration appear to be early indicators of hypovolemia in horses, which may represent acute blood loss in trauma patients; these variables should be monitored to assess the potential need for blood transfusions. These variables can be used to monitor responses of horses to blood transfusions when whole blood is administered as the replacement fluid. 相似文献

Tracheal collapse remains a common clinical problem in middle-aged, small-breed dogs. Clinical signs are characteristic, and the diagnostic work-up serves to identify predisposing triggers of disease and to allow optimization of therapy for individual animals. Bronchoscopic confirmation of airway collapse aids in characterizing the extent of airway damage and allows collection of airway samples to rule out infectious or inflammatory airway disease. Once coincident diseases have been managed, cough suppressants are used to control signs and reduce chronic airway injury. 相似文献

This study was undertaken to determine if pleural effusion (PEF) increases central venous pressure (CVP) in cats, to define any relationship between volume of PEF and CVP and to ascertain the significance of CVP alterations in cats having PEF and suspected right heart failure (RHF). CVP was measured from a jugular vein before (CVPpre) and after (CVPpost) bilateral thoracentesis in 9 cats with naturally occurring PEF and under experimental conditions in 3 spontaneously breathing anesthetized cats receiving graded intrathoracic infusion of saline. Volumes of introduced and recovered fluid were recorded. A significant decrease occurred in CVP after thoracentesis in cats with naturally occurring PEF (mean difference, 4.5 cm H2O; range, 0-7.0 cm H2O, P < .005). The magnitude of change in CVP was constant (r = 0.36, P > .05) over the range of volumes recovered (range, 95-450 mL or 16.4-90 mL/kg). Five cats had CVPpre suggestive of RHF (range, 8.16-20.4 cm H2O). After thoracentesis, RHF was ruled out in 1 cat (CVPpost, 4.08 cm H2O) and the CVP declined but remained abnormally high (9.52 cm H2O) in 1 cat with a mediastinal mass. In 2 cats with confirmed RHF (CVPpre, 20.4 and 16.3 cm H2O), CVP decreased after thoracentesis but remained abnormally high (CVPpost, 14.96 and 10.88 cm H2O). In 1 cat with noncardiogenic PEF and inadequate removal of fluid, CVPpost (8.16 cm H2O) did not decrease. Experimentally, a positive linear relationship was observed between CVP and volume of PEF. The threshold volume required to increase CVP (17 mL/kg) approximated that suggested by clinical observation (22 mL/kg). PEF increases CVP and can cause abnormally high CVP in the absence of RHF. 相似文献

These guidelines have been prepared to assist in the planning, conduct and interpretation of studies for the assessment of the efficacy of acaricides (excluding vaccines and other bio-control agents) against single and multi-host ticks (Ixodidae) on ruminants. Information is provided on the selection of animals, dose determination, dose confirmation and field studies, record keeping and result interpretation. The use of pen facilities is advocated for dose determination and confirmation studies for defining therapeutic and persistent efficacy. A minimum of two studies per tick species for which claims are sought is recommended for each dose determination and dose confirmation investigation. If dose confirmation studies demonstrate greater than 95% efficacy the sponsor may proceed to field studies, where a minimum of two studies per geographical location is preferred to confirm the therapeutic and persistent efficacy under field conditions. If dose confirmation studies demonstrate less than 95% efficacy then longer-term field studies can be conducted over two tick seasons with a minimum of two studies per geographical location. These studies can incorporate other control methods such as tick vaccines, to demonstrate stable long-term tick management. Specific advice is also given on conducting studies with paralysis ticks. These guidelines are also intended to assist investigators on how to conduct specific experiments, to provide specific information for registration authorities involved in the decision-making process, to assist in the approval and registration of new acaricides, and to facilitate the worldwide adoption of standard procedures. 相似文献

OBJECTIVE: To determine whether peripheral venous pressure (PVP) was correlated with central venous pressure (CVP) when measured by use of different catheter sizes, catheterization sites, and body positions in awake dogs and cats. ANIMALS: 36 dogs and 10 cats. PROCEDURES: Dogs and cats with functional jugular and peripheral venous catheters were enrolled in the study. Peripheral venous catheters (18 to 24 gauge) were placed in a cephalic, lateral saphenous, or medial saphenous vein. Central venous catheters (5.5 to 8.5 F) were placed in the jugular vein and advanced into the cranial vena cava. Catheters were connected to pressure transducers and a blood pressure monitor capable of displaying 2 simultaneous pressure tracings. For each animal, the mean of 5 paired measurements of PVP and CVP was calculated. The relationship between PVP and CVP when measured by use of different catheter sizes, catheterization sites, and body positions was determined. RESULTS: Mean +/- SD PVP was 5.7 +/- 5.8 mm Hg higher than CVP in dogs and 6.0 +/- 6.9 mm Hg higher than CVP in cats. However, results of multiple regression analysis did not indicate a significant correlation between PVP and CVP, regardless of catheter size, catheter position, or body position. The relationship was weak in both dogs and cats. CONCLUSIONS AND CLINICAL RELEVANCE: The PVP was poorly correlated with CVP when different catheter sizes, catheterization sites, and patient positions were evaluated. Peripheral venous pressure should not be used to approximate CVP in awake dogs and cats. 相似文献

Background: Central venous pressure (CVP) is used in many species to monitor right‐sided intravascular volume status, especially in critical care medicine. Hypothesis: That hypohydration in adult horses is associated with a proportional reduction in CVP. Animals: Ten healthy adult horses from the university teaching herd. Methods: In this experimental study, horses underwent central venous catheter placement and CVP readings were obtained by water manometry. The horses were then deprived of water and administered furosemide (1 mg/kg IV q6h) for up to 36 hours. Weight, CVP, vital signs, PCV, total protein (TP), and serum lactate were monitored at baseline and every 6 hours until a target of 5% decrease in body weight loss was achieved. The spleen volume was estimated sonographically at baseline and peak volume depletion. Linear regression analysis was used to assess the association of CVP and other clinical parameters with degree of body weight loss over time. Results: There was a significant association between CVP and decline in body weight (P < .001), with a decrease in CVP of 2.2 cmH2O for every percentage point decrease in body weight. Other significant associations between volume depletion and parameters measured included increased TP (P= .007), increased serum lactate concentration (P= .048), and decreased splenic volume (P= .046). There was no significant association between CVP and vital signs or PCV. Conclusions and Clinical Importance: These findings suggest that CVP monitoring might be a useful addition to the clinical evaluation of hydration status in adult horses. 相似文献
