The management of the convalescence is one of the most difficult parts of the treatment and one of the most unsuccessful, not because there is any thing which requires to be done, nor because there is any disease which prevents recovery, but because the patient is considered as well when he is only convalescent. Of the great tendency there is to relapse during the whole of this period few medical men are sufficiently aware, and the unprofessional attendants on the sick are totally ignorant of it. For a long time the brain, the bronchi, and the intestines remain so irritable that the slightest excitement is capable of renewing the diseased action which has recently subsided; but without excitement of some kind, that renewal never takes place. It is the duty of the physician and the nurse to guard the patient from such excitement, which they may always do completely; so that whenever there is a relapse, the physician, or the nurse, or both must be in fault: as long as they perform their duty with judgment and firmness there is no such thing; but this part of their duty which is extremely simple, they cannot be induced to believe to be of importance: no one who has not seen death happen over and over again from the neglect of it will believe it, and even those upon whom melancholy experience has impressed the truth most strongly, constantly allow themselves to be surprised at the slightness of the excitement by which, and the advanced period of the convalescence at which relapse may happen. It is not easy for a nurse to resist incessant importunity and even reproach; and there are suspicions to which a physician is subjected, which, when he sees that they are entertained, it requires some moral courage to enable him to bear. Without doubt he deserves the worst that can attach to him if he allow the caprice, or the impatience, or the injustice of his patient, or any earthly consideration to induce him to swerve from the faithful discharge of the duty he has undertaken. The unreasonableness of the convalescent, should be considered and treated as the delirium of the preceding stage.
