Methods Forty-eight cases of fat milk extravasation after peripheral intravenous infusion, were randomly divided into two groups, 24 cases in each group. 1gL^(-1) phentolamine hydropathic compress was used in observation group, and 500gL^(-1) salamarum hydropathic compress was used in control group. The color, temperature and lump size of local skin were observed after one hour, 12 hours, 24 hours, 48 hours and 72 hour.

选择外周静脉输注脂肪乳过程中发生了外渗外漏的恶性肿瘤晚期患者48例，分为2组，每组24例，观察组采用1gL^(-1)酚妥拉明湿敷，对照组采用500 gL^(-1)硫酸镁湿敷，2组患者分别在开始湿敷后1h，12h，24h，48h及72h观察局部皮肤的颜色、温度及肿块的大小。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
