用猪做实验,常见的困难是采血。猪皮脂厚,血管位置相对较深,在体表不易定位。因此比其它实验动物采血困难,尤其于特殊实验如血气分析需要采集动脉血,该项操作更是不易。为此,笔者摸索了小型猪的采血法,尤其是动脉采血法。材料与方法实验用小型猪是北京农业大学引进育成之品系。共10头雌雄各半,4月龄,体重6—10千克,临床检查为健康动物。 Experiment with pigs, the common difficulty is blood. Pig sebum thick, relatively deep vascular position in the body surface is not easy to locate. Therefore, compared with other laboratory animals, blood collection difficulties, especially in special experiments such as blood gas analysis need to collect arterial blood, the operation is not easy. To this end, I explored the small pig blood collection method, especially arterial blood collection method. MATERIALS AND METHODS Experimental miniature pigs were introduced into the breeding department of Beijing Agricultural University. A total of 10 male and female, 4 months old, weighing 6-10 kg, clinical examination of healthy animals.
