The prevention and treatment of bed-sores have been and are frequently discussed in medical books and journals. But as it is a subject that often taxes the nurse’s ingenuity to the extreme, it can not be dwelt upon too frequently. Many preventive measures are familiar to us, as the soap and water bath for cleanliness, followed by rubbing with alcohol and dusting with boric-acid powder, or boric-acid powder and bismuth subnitrate in equal parts for dryness. _The relief of pressure is most important._ Make use of air-cushions, cotton-pads, pillows, water-bed and _frequent change of position_ where that is possible. In addition to these, there are a few measures not generally used which after a thorough test have proved satisfactory. One is a simple inexpensive contrivance used to relieve pressure of heel, elbow, and ear. It is a pig’s bladder filled two-thirds full of either warm or cold water, as the case requires, tied securely, and placed under a cotton ring. The weight of the head or elbow rests on the ring and the tender point rests on the soft fluctuating mass. If the skin is inactive, as in paralysis, or there is frequent or constant moisture from perspiration or involuntary evacuations of urine or feces, the alcohol and boric acid, etc., are of very little value. They do not prevent the absorption of the moisture by the skin and its subsequent softness or excoriation, which is commonly followed by infection. In such cases the back should be washed with soap and water every six or eight hours, or after every involuntary evacuation, and thoroughly rubbed with a small amount of oil-substance, as camphorated oil or a mixture like the following: Mutton tallow, ℥j; Olive oil, f℥j; Carbolic acid, 95 per cent., ♏︎j. Render out mutton tallow on the back part of the stove; do not brown it. Strain through a piece of muslin; add the olive oil and carbolic acid; set dish into cold water and beat its contents until set. This will make an ointment the consistence of vaseline, and it will keep indefinitely. If the skin needs a great deal of stimulation, camphorated oil or, better still, castor oil may be substituted for the olive oil in the above recipe. When the skin becomes excoriated the part should be cleansed as mentioned before, not with soap and water, but with boric-acid solution, normal salt solution, or sterile water; then gently painted with oxide of zinc ointment made into liquid form by the addition of olive oil, castor oil, and balsam of Peru in equal parts, or castor oil alone, and covered with a clean cloth fastened on with a binder. Gentle massage may be used around the excoriated surface with excellent results.
