Outcomes of Heimlich valve drainage in dogs 总被引：1，自引：1，他引：0
Objective and design Retrospective study of the outcomes of Heimlich valve drainage in dogs.
Procedure Medical records of the past 3 years were retrospectively reviewed. Heimlich valve drainage was used in 34 dogs (median body weight 30 ± 5 kg): lobectomy (n = 15), pneumonectomy (n = 9), intrathoracic oesophageal surgery (n = 2), diaphragmatic hernia repair (n = 1), traumatic open pneumothorax (n = 2), bilobectomy (n = 2), ligation of the thoracic duct (n = 1), and chylothorax and pneumothorax (n = 1 each). Evacuation of air and/or fluid from the pleural cavity was performed with the Heimlich valve following thoracostomy tube insertion. During drainage, the dogs were closely monitored for possible respiratory failure. Termination of Heimlich valve drainage was controlled with underwater seal drainage and assessed with thoracic radiography.
Results Negative intrathoracic pressure was provided in 29 dogs without any complications. Post pneumonectomy respiratory syncope and post lobectomy massive hemothorax, which did not originate from the Heimlich valve, were the only postoperative complications. Dysfunction of the valve diaphragm, open pneumothorax and intrathoracic localisation of an acute gastric dilatation–volvulus syndrome caused by a left-sided diaphragmatic hernia following pneumonectomy were the Heimlich valve drainage complications.
Conclusions The Heimlich valve can be used as a continuous drainage device in dogs, but the complications reported here should be considered by veterinary practitioners. 相似文献

A study of oestrus control in bitches with a new type of progestagen, proligestone, in six Dutch and three UK practices is reported. The product was given subcutaneously, regardless of the stage of the sexual cycle and of the usual contraindications for progestagens. A 97% efficacy was obtained with dosages varying from 20–33 mg/kg for the smallest animals to 10–13 mg/kg for the largest animals, when the first treatment was given in anoestrus with repeated treatments after 3 months, 4 months and thereafter every 5 months.
Following treatment in pro–oestrus, heat symptoms disappeared in 96% of the animals within 5 days. By retreatment after 3 months, oestrus prevention could be maintained in 97% of these cases.
Where the animals had been treated only with proligestone (1608 treatments in 776 bitches) there were five cases of the cystic hyperplasia pyometra complex; none of these occurred after treatment in pro–oestrus. Of the animals previously treated with other progestagens for oestrus control (814 treatments in 307 bitches) there were 11 cases.
Forty–one out of 46 bitches which had a history of reproductive disorders did not show signs again.
Other side–effects were also negligible (<0–5%). Fertility at the first oestrus after treatment appeared normal. 相似文献

This study describes an occurrence of pink morning glory (Ipomoea
carnea) intoxication in goats in northern Argentina. The clinical signs
displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the
neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The
clinico-pathologic examination revealed that the affected animals were anemic and their
serum level of aspartate aminotransferase was significantly increased. Cytoplasmic
vacuolation in the Purkinje cells and pancreatic acinar cells was observed by histological
examination. The neuronal lectin binding pattern showed a strong positive reaction to WGA
(Triticum vulgaris), sWGA (succinylated T. vulgaris)
and LCA (Lens culinaris). Although I. carnea is common
in tropical regions, this is the first report of spontaneous poisoning in goats in
Argentina. 相似文献

The aim of this study was to assess, by a clinical trial, the efficacy of an ivermectin‐based pour‐on treatment against gastrointestinal parasitic nematodes in naturally infected horses using 2 groups of mature indigenous Pura Raza Galega grazing mares. Faecal and blood samples were collected individually over a 21 week period. Faeces were analysed by the coprological flotation, sedimentation and migration techniques. Changes in circulating blood cells were monitored over the study period. The administration of the ivermectin suppressed the eggelimination of ascarids and pinworms throughout the study and no strongyle‐eggs were observed in the treatment group between the 3rd and 10th weeks. The numbers of red cells increased significantly after the anthelmintic therapy, and a statistical reduction in circulating leucocytes was recorded. No side effects were observed. The pour‐on ivermectin formulation was highly successful against gastrointestinal nematodes and appears to be a useful therapeutic routine for large groups of horses. 相似文献

An inverse relationship between a volume estimated to be associated with interphase chromosomes and acute lethal exposure to x-or gamma radiation has been found in 16 plant species. The apparent differences in radiosensitivities found would seem spurious, since the estimated average energy absorbed in the nucleus per chromosome (3.6 x 10(6) ev) approaches a constant (variation less than fourfold) in spite of wide ranges of lethal exposures (0.6 to 75 kr), of nuclear volumes (43 to 1758 micro(3)), and of somatic chromosome numbers (6 to 136). The regression line obtained can be used to predict the radiosensitivities of other plant species if their nuclear volumes and chromosome numbers are known. 相似文献

双链DNA(dsDNA)定量分析是植物分子生物学研究的基础,对基因型分析尤为重要。本研究以λ噬菌体dsDNA为标准样品,建立了荧光定量标准曲线,探讨荧光核酸定量通量性及其与紫外法定量的差异,并分析荧光染料在基因分型中的应用。结果表明,荧光染料能够对dsDNA进行高效微量定量分析(1.1ngmL-1),但因鉴定核酸的浓度较低,对小麦籽粒和叶片全基因组DNA定量时稀释倍数较大,易增大浓度误差。降低反应体系量导致标准曲线决定系数降低,影响测量准确性。精确定量dsDNA浓度时,总反应体系应大于200mL;对PCR产物进行基因分型时,总反应体系应不低于40mL。相同DNA模板浓度下,FLUOstar平台可以对抗秆锈病基因显性标记csSr32#1(Sr32)和IB-267(Sr50)的PCR产物进行基因型分型,判断准确率为100%。对特异性强且等位基因片段差异大(≥100bp)的共显性标记,如抗叶锈病基因标记We173(Yr26)等,用荧光染料同样可以进行基因分型。与琼脂糖凝胶电泳相比,荧光染料鉴定等位基因价格略高,但方法简单、准确快速、重现性好,可用于分子育种中世代材料快速筛选。 相似文献
