=Narcotic Poisoning=: For laudanum, morphine, or opium the treatment is the same. First a strong emetic—mustard and water as thick as pea soup is among the best. Follow it with black coffee as strong as possible. Give all the patient can be made to swallow at short intervals, keep him walking briskly, stripped to the waist, dash ice water on the spine, and tie ice to the back of the neck. Flagellate lightly on shoulders; the tingles help to rouse. Hold aromatic ammonia to his nose every half minute. If the coffee nauseates, give clear hot water after to make vomiting easy, then after ten minutes more coffee not quite so strong. Permit no stop for several hours; if excretories act properly the danger will then have been past. Electricity is useful, but not indispensable. In desperate cases use every means at hand. =Acid Poisoning=: Emollients are the antidotes for acids; emetics wrench and tear seared stomach tissues. No matter what the acid—sulphuric, carbolic, nitric, or oxalic—give something soft and smooth—raw eggs, cream, starch wet as thick as cream, melted lard or butter, olive oil, or even flour and water, followed after a few minutes with magnesia stirred thick in tepid water. Let the patient rest easily, hold ammonia to the nostrils, and put hot-water bags to the feet. Aim to keep up vitality under the shock to vital tissues. In such cases a minute means often the difference between life and death. =Iodine Poison=: Use emollients—the very best is thick cooked starch; it has a specific power to neutralize the drug. Olive oil is next best; it protects the coating of the stomach. But use anything above named rather than nothing. To let a case of poison go by default is against reason and humanity. =Arsenic=: Arsenic in all its forms is best fought with raw eggs, especially the whites, and sweet milk or cream. Give a strong emetic afterward, then, when it has acted, more eggs or milk. This should suffice unless the poison has been freely absorbed. =Ptomaine Poisoning=: Give an active emetic, followed by a cathartic; keep the patient warm, stimulate with brandy—a teaspoonful every hour; put mustard to wrists, ankles, back of neck, and pit of stomach—this particularly if there is severe pain, cramps, or continued retching. Pains in the head indicate the need of an ice cap. =Mercury Poisoning=: Bichloride needs as antidote raw eggs and cream, or oil, with the same external treatment as for ptomaines. Strong emetics are inadvisable, but if the stomach frees itself naturally of the emollients much poison will come with them. Replace them in smaller quantities, but give nothing else until the doctor comes.
