WET-SHEET PACK.
When properly administered, this is one of the most powerful of all water appliances. Some skill is needed to apply it with a uniform degree of success. Two or three comfortables or thick blankets, one woolen blanket, and a large linen or cotton sheet are the articles necessary. It is important to be certain that the sheet is sufficiently large to extend twice around the patient’s body. More blankets are required in cool weather and by weak patients. Spread upon a bed or straight lounge the comfortables, one by one, making them even at the top. Over them, spread the woolen blanket, allowing its upper edge to fall an inch or two below that of the last comfortable. Wet the sheet in water of the proper temperature, having gathered the ends so that it can be quickly spread out. Wring so that it will not drip much, place its upper end even with the woolen blanket, and spread it out on each side of the middle sufficiently to allow the patient to lie down upon his back, which he should quickly do, letting his ears come just above the upper border of the sheet, and extending his limbs near together. The patient should then raise his arms, while the attendant draws over one side of the wet sheet, taking care to bring it in contact with as much of the body as possible, bringing it closely up beneath the arms, and pressing it down between the limbs so as to make it come in contact with both sides of them. Tuck the edge tightly under the patient on the opposite side, using care not to include the other edge of the sheet. Now let the patient clasp his hands across his chest, and then bring up the other side of the sheet. Grasp it by its upper corner with one hand, drawing it down over the shoulder and lengthwise of the body; then place the other hand upon the covered shoulder, holding the sheet firmly in place while the corner is carried upward upon the opposite side and tucked under the shoulder, thus drawing the upper edge of the sheet well up under the chin. Tuck the edge of the sheet under the body, carefully enveloping the feet. Then bring over each side of the blanket and comfortables in the manner last described, being very careful to exclude all air at the neck, and allowing the blankets to extend below the feet so that they can be folded under.
It is not desirable that the patient should be bound as tightly as a mummy. All that is necessary is the exclusion of air, and as the neck and feet are the points at which it is most likely to enter, these parts should receive particular attention, as directed. If too tightly bound, the patient will be more likely to be nervous than if allowed some freedom. The application of the wet sheet should be made in a few seconds, as it cools very rapidly when spread out. The first blanket should be brought over the patient as soon as possible. If the feet are not warm, a hot foot bath should be taken before the pack. If they become cool in the pack, hot jugs, bricks, or stones should be applied to them. If the patient does not become comfortably warm in a few minutes—ten or fifteen at most—more blankets should be added, and, if necessary, dry heat should be applied to the sides. If he still remains chilly, he should be promptly removed and placed in a warm bath, or vigorously rubbed with a dry sheet and then placed in a dry pack. The head should be kept cool by frequent wetting while the patient is in the bath. If a compress is applied, it should be often renewed.
The temperature of the pack must depend upon the condition of the patient, being determined by principles elsewhere explained. A woolen sheet is better for the administration of a hot pack than one of cotton or linen. The cold pack is very rarely required. The usual temperature for this bath should be about 92°. It is proper to wet the sheet in water of about 100°, as it will be cooled several degrees while being applied.
The duration of the pack should be carefully regulated by the condition of the patient, the effects desired, and the immediate effects produced. If the patient becomes very nervous, or sweats excessively, or becomes faint, or has other seriously unpleasant or dangerous symptoms, he should be removed from the pack at once if he has not been more than ten minutes in it. Ordinarily, the pack may continue thirty to forty-five minutes. If the patient sleeps naturally, he may remain in the pack a full hour if strong, or even longer in many cases. In fevers, short packs, frequently repeated, are more beneficial than long ones fewer in number.
The pack should be followed by the spray, the sponge bath, the douche, or the rubbing wet-sheet. It is a powerful remedy, and should not be used to excess in chronic diseases; it has been much abused in this way. Its depurating effects are really wonderful. The increased action of the skin, together with determination of blood to that part, is so great that poisons long hidden in the system are brought out and eliminated. The odor of a sheet recently used in packing a gross person is often intolerable. If the patient be a tobacco user, the sheet will be reeking with the odor of nicotine. Many times, the sheet will be actually discolored with the impurities withdrawn from the body.
The applications of the pack in treating disease are very numerous. In almost all acute diseases accompanied by general febrile disturbance, and in nearly all chronic diseases, it is a most helpful remedy if rightly managed. It is an admirable remedy for nervousness, skin diseases, and irritations of the mucous membrane. The warm pack is a remedy worth more in the treatment of children’s diseases than all the drugs in the materia medica, as many physicians have proved. It is a most successful application in convulsions.
