Having ejected from the stomach all the poisonous matter we can by vomiting, and attempted to decompose what remains, we are to pursue such measures as may be calculated to prevent the absorption of the poison into the circulation; it has been already observed that on this account nauseating emetics should be avoided; the reader is now requested to refer to our exposé of the celebrated doctrine of Majendie, (page 86, note) and he will see that Venesection proves one of the most powerful means of exciting the function of absorption; hence in poisoning by arsenic, such an expedient should never be recommended,[231] while a particle of that substance remains in the body; where Corrosive Sublimate has been swallowed, the same precaution is unnecessary. The last indication which remains to be fulfilled is—
3. To anticipate the occurrence of the Consecutive Phœnomena, and to combat them by appropriate treatment.
This is to be conducted on the general principles of Therapeutics; the treatment must necessarily vary in each particular case. Where the exhaustion of nervous energy is to be feared, as after poisoning by Prussic Acid, ammonia, and other diffusible stimulants, together with external warmth, will furnish the best resource; for the same reason Venesection should be performed with great caution and judgment after a narcotic poison. Where, on the other hand, inflammatory action is to be anticipated, it is unnecessary to detail the plan of treatment which may be adopted with the greatest chance of success. In cases where the nervous system is stupified, the symptoms may be combated by vegetable acids, infusion of coffee, &c. but where it is in a state of præternatural excitement, recourse must be had to opiates.
