The patient should remain in the pack as long as he does not become too hot or restless. This may occur after 20 to 30 minutes, in case of severe fever; otherwise, the pack may last an hour or longer. The pack is very useful with children when indications of disease appear. In many cases it will develop and cure disease, such as measles, if it is properly applied for 2 to 2-1/2 hours, and followed by a bath at 77 degrees or an ablution at 64 degrees. When fever and inflamation begin to slacken, and also during convalescence, three-quarter or whole packs applied daily or every second day, followed by an ablution, are very useful for the purpose of solution and excretion. In such cases the moist heat should be conserved by applying additional blankets or comforters to the limit of endurance. THE HALF PACK (25) The half pack is applied like the three-quarter pack, with the exception that it reaches only from the arm-pits to the knees. It is especially necessary to close it carefully around the legs. The half pack allowing the body more freedom, it may be kept on all night. It is most effective on the thighs in cases of sciatica. It is, however, also applied in case of febrile disease. THE WHOLE PACK This is applied in nearly the same way as the three-quarter pack, but includes also the arms, breast and neck. [Illustration: No. 9] In this case the blanket must reach to above the ears. On top of the moist spread a towel is laid, which is first drawn around the abdomen. The patient's arms must be somewhat bent, so that they will not oppress the breast when packed with it. Otherwise the arms may be treated just like the legs, so that the moist spread touches them everywhere. When it is impossible to fasten the blanket at the neck with safety pins, it can be tucked firmly under both shoulders. The blanket must be drawn tightly over the shoulders and the ends tucked under the opposite shoulder. It must exceed the length of the patient by 18 inches. In case one blanket is not large enough, two must be used, one of which may be drawn down 6 inches below the other. [Illustration: No. 10] Additional blankets, pillows and comforters may be used in case of high fever. The advice already given in regard to the differences in packs, depending on their various purposes of cooling, diverting, calming or dissolving, must also determine in this case as to the extra amount of covering. The access of cold air at the neck and legs, however, must always be carefully guarded against. An ablution or bath must follow each whole pack. If properly applied, the "whole pack" will be of the greatest benefit in all febrile and chronic cases. Inflammations require partial packs, while at the same time dissolving or diverting packs of longer duration are applied to the parts of the body which are not affected. SMALL COMPRESSES Small compresses may be applied to any part of the body.
