Objective
To evaluate the behavior and some cardiopulmonary variables of dexmedetomidine–midazolam or dexmedetomidine–midazolam-butor-phanol in the silver fox (Vulpes vulpes).Study design
Blinded, randomized design.Animals
Sixteen adult silver foxes, aged 7–9 months, weighting 6.0–9.2 kg.Methods
Animals were randomly assigned to dexmedetomidine (50 μg kg?1) and midazolam (0.45 mg kg?1) (group DM) or to dexmedetomidine (30 μg kg?1), midazolam (0.45 mg kg?1) and butorphanol (0.25 mg kg?1) (group DMB), administered intramuscularly. Pulse rate (PR), respiratory rate (fR), noninvasive arterial pressures, oxygen saturation (SpO2), rectal temperature (T) and behavioral scores (posture, sedation, antinociception, jaw relaxation and auditory response) were measured at 5, 10, 20, 30, 40, 50 and 60 minutes after injection. Time from drug injection to recumbency with no response to stimuli (IT) and time from administration of atipamezole (0.2 mg kg?1) to standing with coordination (RT) were recorded. The occurrences of adverse events were recorded. Data were analyzed by two-tailed unpaired t-tests and Bonferroni post hoc tests. Significant differences were accepted at p<0.05.Results
There were no statistically significant differences between the groups for IT or RT. Arterial pressures were higher in DMB at each time point except at 5 minutes. PR was lower in DM at each time point except at 10 and 60 minutes. No significant difference was found between the groups for fR, SpO2 and T. The behavioral scores were significantly lower (lower quality immobilization) in DMB at 5,10 and 60 minutes.Conclusions and clinical relevance
IT and RT were not different between the groups. Both protocols provided immobilization for 30–40 minutes with excellent muscle relaxation and analgesia adequate for clinical examinations and some simple surgical procedures. 相似文献32.
长江上游白鲟幼鱼形态发育和产卵场的调查研究 总被引：3，自引：0，他引：3
１９８９年３月至１９９１年６月对长江重庆江段１９尾白鲟（体长４８０～１１４８ｍｍ）的形态、生长和食性进行了分析及年龄鉴定。结果表明，幼鲟生长较快，身体各部分增长不一致，眼径、吻须增长较慢。其体长（ＢＬ）、体重（Ｗ）的关系式为：Ｗ＝５．２１１９×１０－６ＢＬ２．９２７１。白鲟为肉食性鱼类，体长约６４７ｍｍ的幼鲟主要摄食小型鲤科鱼类。葛洲坝截流后，长江上游白鲟产卵场未变，种群数量有所回升。 相似文献
