Five horses were presented for treatment of atrial fibrillation by transvenous electrical cardioversion (TVEC). A dexmedetomidine infusion was administered for sedation during positioning of the cardioversion catheters, and continued during general anesthesia. Shocks were applied until return to sinus rhythm. Dexmedetomidine infusion provided excellent conditions for TVEC catheter placement and procedure. 相似文献

The purpose of this study was to evaluate plasmapheresis as a method for plasma extraction in comparison with centrifugation or gravity sedimentation. The study was designed as a cross over trial with six Freiberger horses undergoing plasma donation by plasmapheresis followed by whole-blood donation and subsequent plasma production 4 weeks later. Automated plasmapheresis and whole-blood donation were well tolerated in all horses. The plasmapheresis method achieved an almost complete removal of erythrocytes and leucocytes from plasma at all flow rates. After blood bag centrifugation, significantly more erythrocytes (P < 0.01) and leucocytes (P < 0.01) were present in the prepared plasma compared with plasmapheresis plasma. Plasma prepared by gravity sedimentation contained significantly more erythrocytes and leucocytes than plasma prepared with the other techniques (P < 0.01), and platelet aggregation was observed. The coagulation proteins and the total protein content of plasma prepared after plasmapheresis and blood bag centrifugation did not differ significantly from values measured prior to collection (P > 0.05). However, the activity of factor VIII was significantly lower 24 h after gravity sedimentation of blood than activity prior to blood collection (P < 0.01). In conclusion, automated plasmapheresis is the method of choice for the production of high quality equine plasma. 相似文献

REASONS FOR PERFORMING STUDY: Unfractioned heparin (UFH) is widely used for prophylaxis of coagulation disorders, especially in colic-affected horses. However, it is accompanied by certain side effects. OBJECTIVES: To compare the efficacy and side effects of unfractioned and low molecular weight heparin (LMWH) in horses with colic. METHODS: The study was carried out as a randomised, double-blind, controlled clinical trial. Fifty-two horses with colic were treated subcutaneously with either UFH (heparin calcium, 150 iu/kg bwt initially, followed by 125 iu/kg bwt q. 12 h for 3 days and then 100 iu/kg bwt q. 12 h) or LMWH (dalteparin, 50 iu/kg bwt q. 24 h). All horses underwent daily physical examination including assessment of jugular veins, local reaction to heparin injections, haematological evaluation and coagulation profiles over up to 9 days. RESULTS: The type of heparin used did not affect the general behaviour and condition. There were significantly more jugular vein changes in horses treated with UFH. Packed cell volume decreased significantly within the first few days of UFH treatment, but did not change significantly in horses treated with LMWH. Activated partial thromboplastin time (aPTT) and thrombin time (TT) were prolonged in horses treated with UFH but not in those treated with LMWH. CONCLUSIONS: It was concluded that, in comparison to UFH, LMWH has markedly fewer side effects in horses. POTENTIAL RELEVANCE: Therefore, LMWH is recommended for prophylaxis of coagulation disorders in colic patients. 相似文献

Three groups of horses and ponies (N = 13, 13 and 12) were treated with ivermectin paste (0.2 mg/kg p.o.), avermectin B1 solution (0.2 mg/kg p.o.), or fenbendazole suspension (10 mg/kg via nasogastric tube). The avermectin B1 was a 1% solution in a propylene glycolglycerol formal base. Faecal strongyle egg counts were performed before, and 14, 28, 42, 56 and 70 d, after treatment. Full-thickness skin biopsies from the neck, pectoral and umbilical regions were examined for Onchocera microfilaria before treatment, and again 14 and 70 d later. Ivermectin therapy produced a significant (P less than 0.01) decrease in mean strongyle egg counts 14, 28, 42 and 56 d after treatment. Avermectin B1 therapy resulted in significant (P less than 0.01) decreases in mean strongyle egg counts 14, 28 and 42 d after treatment. All horses given ivermectin or avermectin B1 had zero strongyle egg counts 14 and 28 d after treatment. Fenbendazole failed to significantly decrease strongyle egg counts. Both ivermectin and avermectin B1 resulted in zero microfilaria counts in all horses 14 d after treatment. On day 70 the percentage decrease in microfilaria counts were 100% and 99.6% respectively. Fenbendazole failed to significantly decrease microfilaria counts. The oral administration of this formulation of avermectin B1 appeared to be highly efficacious against intestinal strongyles and Onchocera microfilaria. The duration of anti-strongyle activity was, however, significantly (P less than 0.01) shorter than that of ivermectin paste. 相似文献
