ObjectiveTo evaluate the antiemetic effect of butorphanol (BUT) when co-administered with dexmedetomidine (DEX) in cats.Study designDouble-blind, randomized controlled cross-over experimental study.AnimalsFourteen purpose-bred healthy Domestic Short Hair cats, seven females and seven males, aged median (range) 14–84 (78) months and weighing 1.7–5.5 (4.0) kg.MethodsEach cat received five different treatment protocols intramuscularly (IM): (A) 25 μg kg−1 DEX; (B) 20 μg kg−1 DEX and 0.2 mg kg−1 BUT; (C) 20 μg kg−1 DEX and 0.1 mg kg−1 BUT; (D) 25 μg kg−1 DEX and 0.2 mg kg−1 BUT; and (E) 20 μg kg−1 DEX. Episodes of emesis, incidence and severity of nausea, and time to lateral recumbency were recorded for a period of 8 minutes after treatment administration, and the sedation was scored at the end of this period. The Friedman test and the Cochran’s Q-test were used to analyse the data. Significance was evaluated at the 5% level.ResultsThe proportion of cats that vomited was significantly lower with the treatment protocols that included BUT (B, C and D) compared with the protocols that included only DEX (A and E). The proportion of cats that had nausea was significantly higher with the protocols that included only DEX (A and E) compared with protocols B and D. Time to lateral recumbency (p = 0.09) and sedation score (p = 0.07) was not statistically different between the treatment protocols.Conclusions and clinical relevanceButorphanol can be used to prevent emesis and reduce the incidence and the severity of nausea caused by DEX in cats. It seems that the combination of BUT and DEX is very useful not only when emesis could result in serious complications, but also to provide comfort and well-being in cats sedated for minor procedures. 相似文献

BackgroundThe recommended doxorubicin (DOX) dose for small dogs is 1 mg/kg. Recent data suggest that DOX‐induced gastrointestinal (GI) toxicosis can be reduced with maropitant treatment.ObjectivesTo investigate the incidence of adverse events (AEs) in small‐breed dogs administered a single 25 mg/m2 DOX followed by administration of maropitant (DOX25). The primary aim was to assess myelo‐ and GI toxicoses for 2 weeks after DOX administration. The secondary aim was to compare the incidence and grades of AEs found in the DOX25 group with a historical control group (DOX 1 mg/kg without administration of antiemetic or antidiarrheal medications).AnimalsNineteen small‐breed tumor‐bearing dogs.MethodsA prospective, observational study of tumor‐bearing dogs, weighing 5 to 10 kg, administered a single 25 mg/m2 dose of DOX IV, followed by administration of maropitant for the next 5 days.ResultsInappetence, vomiting, and diarrhea were found in 7/19, 2/19, and 6/19 of the DOX25 dogs, respectively. Neutropenia and thrombocytopenia was 12/19 and 3/19, respectively. Most AEs were grades 1 and 2, except for grades 3 and 4 inappetence and neutropenia in 3 and 4 dogs, respectively. Furthermore, febrile neutropenia occurred in 3/19 dogs in the DOX25 group. All AEs between the DOX25 and historical control groups were not significantly different.Conclusions and Clinical ImportanceVomiting and diarrhea were deemed acceptable with 25 mg/m2 DOX followed by maropitant treatment in 5 to 10 kg dogs; however, additional supportive care might be needed for dogs with inappetence and neutropenia. 相似文献
