=During a convulsion= the animal should be freed from all harness, halters, girths, etc., that would impair respiration, the jaws may be kept apart with a cloth to prevent biting the tongue, and the animal held with head and neck in natural position. To arrest the spasms the best agent is amyle nitrite inhaled from a handkerchief. It may be replaced by a mixture in equal parts of chloroform and ether. Or rectal injections may be given of chloral. Nitro-glycerine will sometimes cut short an attack or prevent it. Small animals may have the body immersed in a warm bath, and cold applied to the head. Congested buccal and conjunctival mucosæ would indicate cold to the head, while pallor would suggest warm fomentations. When the fit is over the animal should be kept in a quiet, dark place until the excitement or stupor has completely passed. ECLAMPSIA. CONVULSIONS. SPASMS. Definition: functional convulsions from peripheral irritation. From dentition, helminths, uterine disease, nursing (anæmia). Treatment. Injuries to cranial bone. Eclampsia (convulsions) is difficult to define as distinct from epilepsy, the present tendency however appears to be to apply this term to cases in which the spasms are of a purely functional nature as far as the brain is concerned and caused by peripheral nervous irritation. Whereas in epilepsy there is some organic disease or disorder of the brain itself. Therefore the convulsions of anæmia, of teething, and of parasitism, would come under this heading being curable by the removal of the distant source of irritation, while the spasmodic seizures, that are due to central nervous lesions and are not exclusively dependent on peripheral irritation would be classed as epilepsy. In other words reflex epilepsies with no central brain disorganization would be classed as convulsions. _Eclampsia from_ =Dentition= is seen especially in young cats, dogs and pigs when cutting-teeth, and may be obviated by lancing the gums, extracting diseased or milk teeth entangled on the crowns of their successors, and by a slight laxative with bromides. _Eclampsia from_ =Helminthiasis= has been already referred to under epilepsy. The main object is the expulsion of the worms, after which nerve sedatives and tonics will be valuable. _Eclampsia from_ =Uterine Disease= has been noticed by Albrecht, in cows shortly after calving, the symptoms being spasms of the neck, persistent extension or turning of the head, grinding of the teeth, loss of consciousness, convulsive movements of the legs, rolling of the eyes, and slow recovery. The same symptoms have been observed in goats and have been supposed to depend on a reflex from the irritated womb. Another supposable cause is the absorption of toxic products from the womb and vagina. Manifestly the removal of the after birth and the disinfection of the womb, should be here employed along with the ordinary nerve sedatives.
