Since the effect of the douche depends on the pressure, it will be readily understood that the hose attached to the faucet of the domestic bath-tub is merely a sprinkler, and not a douche, in the proper sense of the word. Such a procedure can only be tolerated by the most robust. In the upper stories of most city houses the pressure is probably not more than from 3 to 10 pounds; the stream of water from the sprinkler is really only a drizzle; the mechanical effects being so slight, there is no reaction produced; the result is that its use is followed by a feeling of chilliness and depression. =The Hot Foot-bath.=—The temperature of this bath should be at the beginning from 102° to 104° F., and the duration from three minutes to half an hour. The pail is nearly filled with water, care being taken that it shall not be so full as to overrun when the feet and legs of the bather are put in. A blanket, closely wrapped about the patient and the pail, should come up above the knees. As the water cools off, hot water should be added. This form of bath is most commonly used to relieve congestion and inflammation. The dilatation produced in the blood-vessels of the feet and legs relieves congestion of the brain and the organs of the upper half of the body, as well as of the pelvic viscera. It should be taken immediately before retiring. =The Sitz Bath.=—The sitz or hip bath requires a tub made for that particular purpose. The back of the tub, which is most commonly made of tin, is cut high, while the front must be sufficiently low for the patient to sit comfortably in it, without undue pressure being made on the under side of the knees. The tub is half filled with water of the prescribed temperature. It is well to begin with water at a temperature of 102° F., and increase the temperature while the patient is in the tub, making it as hot as is comfortable. [Illustration: Fig. 2.—Sitz-bath tub made of tin (Ashton).] In giving all hot baths a thermometer must be used, and a word of warning must be given about adding hot water in case of sickness, as well-authenticated cases of paralysis are recorded in which the temperature sense of the patient was lost, and, in adding hot water, it was raised to such a temperature that the legs and feet of the patient were scalded. During the sitz bath the patient keeps on her stockings and bedroom slippers, and, unless friction is ordered, the entire body, as well as the feet and legs, are enveloped in blankets. The duration of this bath is from three to ten minutes. This bath is especially useful in restoring the menstrual function when it has been suspended as the result of chill or other causes; also, for relieving hemorrhoids, uterine colic, neuralgia of the ovaries, and inflammation of the bladder.
