Suffocation.—Remove the patient immediately to the fresh air; dash cold water in the face and on the chest; keep up the warmth of the body, and apply mustard plaisters over the heart and round the ankles. If these means fail, without loss of time try artificial respiration, as already described.
Before entering a suffocating atmosphere to rescue persons, tie a towel soaked in vinegar and water over the mouth. Admit fresh air to the room if possible.
Fits, Fainting, and Unconsciousness.—These bear a strong outward resemblance to each other while due to very different causes. The latter are principally: (a) injuries to the brain, with or without fractures of the skull; (b) diseases of the brain (including fits), apoplexy, epilepsy, &c.; (c) poisoning by narcotics and by retention of urine (in kidney disease); (d) fainting (paralysis of the heart through fright, exhaustion, loss of blood, &c.).
In such cases gather a history of the occurrence, and note the position of the body and its surroundings; also whether the breath smells of spirits, which shows there has been drinking, but remember that other and more serious conditions (paralysis, injury to the brain, &c.) may co-exist with intoxication. Lay the body on the back, with the head low if the face is pale, as in faintness after great loss of blood. If the face is red, the head must be raised. If sickness sets in, incline the head at once, so that the vomited matters may not be drawn into the lungs. Undo all clothing round the neck. Allow free circulation of air round the patient. Remove the patient as quickly as possible to the nearest hospital or doctor on a stretcher.
In epileptic fits, recognised by convulsive spasms of the limbs and body, contorted and congested face, foaming at the mouth, and bitten tongue, act on the rules just mentioned, and do all in your power to prevent the patient injuring himself, without attempting to restrain his movements. Lay something soft under his head, put something between the teeth, watch till the fit is over, and then remove him. In cases of fainting at once lay the patient flat, with the head brought to the same level as the body, to enable the blood more easily to circulate through the brain, for it is want of power in the heart to propel the blood to the brain that has caused the insensibility. If bleeding is going on, it must at once be arrested. As stimulants, eau de Cologne, sal volatile, ammonia, &c., may be used, but the important thing to remember is the position of head and body. Stimulation is apt to start afresh the bleeding arrested by fainting. In cases of snoring, with face flushed (apoplexy), undo clothing round the neck, keep the head raised, dash cold water on the top of the head, and apply hot-water bottles to the feet; send for doctor; do not give brandy.
Frostbite.—In serious frostbite or cases of exposure to intense cold, endeavours to restore life should be made with the greatest care. If you bring the patient suddenly into a warm room, death will follow certainly. Carry him carefully into a closed but cold room, and undress him with care for fear of breaking the stiffened limbs. If snow is to be had, cover and vigorously rub the whole body with it. If not, cover and rub with cold wet cloths or cold sand, or put him into a cold bath. Alternately with this try artificial means to restore breathing (as in drowning). When the patient begins to breathe naturally, and the limbs become less stiff, he should be carried into a moderately warm room and covered lightly with cold coverings and sheets. After this, he may be rubbed by degrees with warm cloths, and the warmth of the room gradually increased. Then try by means of smelling-salts, ammonia, or ether, and slightly stimulating drinks, such as light cold wine, cold coffee or soup, to recall consciousness. Should any part of the body remain without sensation, blue, swollen, or blistered, there is great danger of mortification setting in.
For after consequences, which recur most frequently in cold weather, apply balsam of copaiba, spread thickly on a piece of linen or muslin, the affected parts being covered with the application, which is allowed to remain over the night. By day, some of the balsam is to be spread over the affected parts. After one or two applications the pains cease and the redness disappears; whilst a few additional applications seem to give to the parts a power of resistance to frostbite.
Dr. Lapatin advises that fingers and toes which have been slightly frost-bitten, and which subsequently suffer from burning, itching, and pricking sensations, should be painted, at first once, and afterwards twice a day, with a mixture of dilute nitric acid, and peppermint water in equal proportions. After this application has been made for 3-4 days, the skin becomes darkened and the epidermis is shed, healthy skin appearing under it. The cure is effected in 10-14 days.
The members of the Austro-Hungarian Polar Expedition found most benefit from a mixture of iodine and collodion.
Lightning Stroke.—Apply cold to the head, and, if necessary, warmth to the extremities; rub the limbs well, and give stimulants as soon as the patient can swallow.
