neutral saline？

. . . soon the sharpened features, and sunken eye, and fallen jaw, pale and cold, bearing the manifest impress of death’s signet, began to glow with returning animation . . ..

^……很快，他那原本棱角分明的五官，凹陷的眼睛，塌陷的下巴，苍白冰冷的面色，明显带有死亡的印记，开始焕发新生^……

苍白而冰冷前面需要加“面色”吗？或者这么翻译有问题吗？谢谢

During the British cholera epidemic of 1831, William O’Shaughnessy reported that the blood of victims “has lost a large portion of its water . . .a great proportion of its neutral saline ingredients” and that “of the free alkali contained in healthy serum, not a particle is present in some cholera cases.”1 He advocated for the restoration of the missing water and salts, an approach that was embraced by the Scottish general practitioner Thomas Latta, who reported the striking resuscitative effects described above.2 Two centuries later, key questions remain: which fluids, how much, and toward what targets?

1831年的英国霍乱流行期间，William O’Shaughnessy报告说，患者的血液“丢失了其大部分水^……中性体液成分占很大比例”和“某些霍乱患者中缺乏健康血清该有的游离碱”他主张恢复缺失的水和盐，这种方法被苏格兰全科医生Thomas Latta所采纳，他报告了上述惊人的复苏效果。两个世纪后，输液的关键问题仍然存在：输什么液体、多少液体和输液的目标是什么？
