These measures should never be attempted by anyone who has not had an extended practical experience. Much can be accomplished by hydrotherapy in the alcoholic and toxic conditions, infective and exhaustive psychoses, manic excitements, involutional melancholia, hysterical and neurasthenic conditions, as well as in occasional cases of dementia praecox. Occupational therapy has been used to great advantage in connection with the hydrotherapeutic treatments. In the reception service and in the buildings for the noisy and violent cases ample facilities should be at hand for the continuous bath treatments. Pack rooms are also desirable. There is no means at our disposal equal in any way to the efficacy of the continuous bath in controlling excitements. The patient is usually kept in the tub from five to eight hours at a temperature varying from 92 to 97 degrees and averaging 96 degrees. In some hospitals they are kept in the tubs for periods of from two to three weeks. The continuous bath is of no value unless it means what the name implies—the continuous submersion of the body in water. In dealing with very excited cases this necessitates the use of a tub cover and a hammock, although sheet coverings are often used satisfactorily. Not much is to be gained by the tub bath if the patient is to be allowed to get out and in as he pleases and only come into partial contact with the water. The continuous bath is not without drawbacks. There is danger of chilling, scalding and drowning either by accident or with suicidal intent, etc. Too much care cannot be exercised in the supervision of the bath rooms. Every tub room in the Boston State Hospital has the following rules conspicuously displayed:— THE CONTINUOUS BATH ROOM 1. The nurse on duty in the bath room will be held personally responsible for the safety of the patients and must be thoroughly familiar with these rules. The nurse must never leave the room unless relieved by some other nurse. Eternal vigilance is necessary to prevent the chilling, scalding or drowning of the patient. 2. Patients are to be given continuous baths only on the written order of a physician. 3. Patients going to or from the bath room must wear a nightdress or bathrobe and slippers when not fully clothed. 4. Tubs not in good condition or not properly equipped must not be used. 5. Only patients under treatment are allowed in the room. 6. Toilet each patient just before the bath. Patients may be removed from the tub for toilet purposes when necessary. 7. In preparing for the bath, warm the tubs with hot water and then regulate the temperature so that a small amount of water at 96 degrees will be flowing continually. 8. Adjust the hammock to the tub and place the patient in the bath resting on the hammock. Adjust the cover to the tub, with patient's head through the neck opening unless sheets or other covers are used.
