Here we may ask, Will opium aid, or give the relief so urgently demanded? However serviceable as an astringent and anodyne in the premonitory stage of the disease, it cannot be exhibited in the second stage to so good an advantage, as its direct influence is to aid and promote congestion in those cases, where a tendency of this kind is already in existence. Hence, its continuance in the true or collapse stage of cholera is now generally considered faulty. Once more: The auxiliaries employed in aid of the leading remedies already noticed may be summed up in the language of the celebrated Dr. Massy, in his instructions and directions on the subject of the treatment now under consideration. He observes, "But, as you draw blood, stimulate, give punch, brandy, or wine and water, or carbonate of ammonia. Apply friction, with stimulating and hot liniments to the extremities; warm sand-bags to the feet, sinapisms to the calves of the legs and pit of the stomach; for, if you can once raise the pulse, the chances in favor of recovery will be vastly increased." To these directions there can be no special objections, except in the first instance in which he, indirectly, commends the use of means tending to deplete and depress the system, already brought by disease to the very verge of utter exhaustion. Remedies of this tendency are contra-indicated, and cannot, to say the least, be employed to advantage. Depressing remedies generally, instead of checking, or counteracting the disease, will inevitably aid and hasten its fatal termination. Stimulants, such as are prompt and diffusive in their character, must be regarded as essential, and may be employed to great advantage. It will be found, however, exceedingly difficult in most cases, even where there is no depletion from bleeding, to keep up the waning powers, and carry the patient, through this formidable disease, to a favorable termination. Of the utility of warm applications to the surface generally, there can be no question; yet, our main reliance is on internal remedies, as has been already shown: the lost temperature of the body must be restored, the production and diffusion of heat, or caloric, must be internal through the administration of remedies, that will promptly and kindly produce this result. What are, then, the remedies? We have ventured in this discussion to recommend the internal use of chloroform, and believe it will be found in combination with other prompt and diffusive stimulants, specially adapted to meet this condition. In this recommendation, we feel ourselves fully sustained by the result of various experiments heretofore made, and the recent trials of its use, as an internal remedy in the various stages of the disease.
