In the case of the ear, unless the obstruction can be easily seized with the finger-tips, it should be permitted to remain until a physician arrives with the proper instruments to remove it. In a mother’s effort to dislodge it, she may push it farther against the canal or drum of the ear. Earache is one of the most trying emergencies in the nursery. It is an exquisite form of torture. It keeps both mother and child awake. It may be accompanied by fever; and in the infant who cannot locate the pain for the mother, it is indicated by irritation, restlessness and drowsiness, loss of appetite and nausea. The child tosses the head from side to side, not restlessly but violently, according to the intensity of the pain. The tiny hands make constant but futile efforts to reach the seat of the pain. If the attack is recurrent a specialist should be consulted, as sometimes an incision of the drum is necessary to relieve the pain. This does not affect the hearing of the child if properly done. In the meantime, heat may give some small relief. This may be applied with hot compresses, a bag containing hot salt, or even a hot-water bottle wrapped in flannel. The ear may be irrigated with hot boric acid solution in the proportion of one teaspoonful of boric acid to a pint of water. This may be poured into a fountain syringe, which is held two feet above the child’s head, the small nozzle of the syringe may then be held from one-quarter to one-half inch from the opening in the ear. It should never be pressed far enough into the ear to touch the drum. This warm water injection may be repeated every three or four hours, and where the ear discharges, either because of the incision made by the doctor or when the drum has burst of its own accord, the injection should be given three times a day as long as the discharge lasts. The best solution of the poison emergency in the nursery is to keep poisons of every kind out of the reach of children. This includes Rough-on-Rats, corrosive sublimate tablets, carbolic acid, oxalic acid, laudanum, and strychnine. Rough-on-Rats is full of arsenic. Oxalic acid is kept in the house to take out stains, particularly of ink; carbolic acid and corrosive sublimate for disinfecting; laudanum for toothache. They should all be plainly marked for the protection of adults, and should be placed absolutely beyond the reach of baby hands. If, however, a child does swallow any of these, use the following antidotes: _Carbolic acid_: If taken internally, give epsom salts in large doses, soap; but no sweet-oil or castor-oil. For external burns apply alcohol. _Oxalic acid_: Give an emetic, such as tepid mustard water, followed by a dose of chalk or whiting or vinegar. Follow this with soothing drinks, like warm milk. Never give potash or soda in any form. _Ammonia_: Children have been known to drink ammonia with fatal results. Give vinegar or lemon juice, immediately followed by warm milk or sweet-oil.
