曾看到这样一段话:疼痛不但可以提醒我们什么时候受伤了,同时会阻止我们受更大的伤害;不仅会告诉我们正处在或大或小的危险之中,同时也引导医生用最恰当的方式去解除这种危险。无痛病人之所以是危险的,因为这不但会使病人自己失去警觉,而且会使医生丧失寻常的审慎。 Have seen this passage: pain can not only remind us when wounded, but will also prevent us from being more hurt; will not only tell us is in danger of being larger or smaller, but also guide the doctor to use the most appropriate Way to get rid of this danger. Painless patients are dangerous because not only can they lose their alertness to their patients, but they can also make doctors lose their normal prudence.
