After recovering
from the acute form of poisoning, the patient may ultimately die from
starvation, due to stricture of the oesophagus, stomach, etc.
_Post-Mortem Appearances Common to the Mineral Acids._--Stains and
corrosions about the mouth, chin, and fingers, or wherever the acid has
come in contact. The inside of the mouth, fauces, and oesophagus, is
white and corroded, yellow or dark brown, and shrivelled. Epiglottis
contracted or swollen. Stomach filled with brown, yellow, or black
glutinous liquid; its lining membrane is charred or inflamed, and the
vessels are injected. Pylorus contracted. Perforation, when it takes
place, is on the posterior aspect; the apertures are circular, and
surrounded by inflammation and black extravasation. The blood in the
large vessels may be coagulated.
Avoid mistaking gastric or duodenal ulcer, with or without perforation,
for the effects of a corrosive poison.
_Treatment._--Calcined magnesia or the carbonate or bicarbonate of
sodium, mixed with milk or some mucilaginous liquid, are the best
antidotes. In the absence of these, chalk, whiting, milk, oil,
soap-suds, etc., will be found of service.
