Opium poisoning characteristically causes progressive unconsciousness with dangerously depressed breathing; acute poisoning by soluble antimony compounds chiefly causes violent gastrointestinal illness and collapse. Each requires its own differential diagnosis and treatment. The historical discussion below describes an 1866 examination answer; the present medical explanation is distinguished explicitly.

With opium poisoning, early drowsiness progresses to deep coma. Pupillary constriction, slow shallow breathing, snoring or gurgling breathing, a limp body and cyanosis are important findings. Failure to wake the person, together with depressed breathing, is more significant than apparent peaceful sleep. The pupils need not remain small in advanced hypoxia, and a single sign cannot establish the diagnosis.^[ref]

An 1866 practitioner would seek to remove unabsorbed opium by a stomach pump or an emetic, try to rouse the patient, and sustain breathing by artificial respiration. The contemporary encyclopedia explicitly states that no antidote was known. For antimony, the same source recommended a decoction of Peruvian bark; such tannin-containing preparations belong to the history of attempts to render the poison insoluble, not to a demonstrated modern antidote regimen.^[ref]

In present practice the immediate priorities in severe opioid poisoning are an open airway, adequate pulmonary ventilation and urgent medical support, together with naloxone to reverse the opioid effect. Continued observation is needed because respiratory depression can return after reversal. Pouring liquids into the mouth or inducing vomiting can cause aspiration; efforts to rouse the person must not delay effective breathing support.^[ref][ref]

The principal mimics of opium poisoning include alcohol intoxication, a stroke formerly described as “apoplexy”, and other causes of coma, such as hypoglycaemia or uraemia. Establish the sequence of symptoms and exposure, examine breathing and the pupils, and look for focal neurological signs. Odour of alcohol does not exclude a second poison or a stroke. Modern testing of blood glucose and appropriate neurological assessment complement the exposure history; urgent treatment of failed breathing must not await a chemical identification.

For antimony poisoning, the important period exposure is tartar emetic, or antimony potassium tartrate. Acute ingestion may cause nausea, repeated vomiting, abdominal pain, profuse diarrhoea, thirst, weakness and circulatory collapse. Loss of water and electrolytes compounds the toxicity. Present knowledge also recognizes serious cardiac effects; repeated exposure may produce continuing gastrointestinal illness and weakness rather than one dramatic attack. The chemical form matters: these findings should not be generalized to every exposure to metallic antimony.^[ref]

The closest clinical confusions are cholera, severe gastroenteritis, and poisoning by other irritants, especially arsenic. Recurrent attacks associated with particular food or medicine, persistence outside an outbreak, and chemical examination of vomit, excreta and suspected preparations help distinguish them. These are clues for investigation, not grounds for declaring a particular person guilty.

Modern management of antimony poisoning stops further exposure, supports breathing and blood circulation, replaces fluid and electrolyte losses, and monitors cardiac arrhythmias and organ function. A specialist determines whether decontamination or chelation is appropriate. The institutional monograph records sparse human evidence for chelation; it does not justify presenting a tannin drink or any chelator as a certain cure. It is a later, explicitly dated toxicological comparison, not the treatment available to the 1866 candidate.^[ref]

The guide is the diagnosis and the physiological cost of persistent vomiting, not the symptom alone. Establish whether material is truly vomited, search for local and extra-gastric causes, correct depletion and then treat the cause. A distinction between vomiting, passive regurgitation and rumination syndrome prevents several different disorders being forced into one category. First assess inability to retain fluid, weight loss, dehydration, gastrointestinal bleeding, severe abdominal pain or distension and neurological signs. Significant danger requires prompt investigation and support before a prolonged trial of symptom remedies.^[ref]

The history should establish duration, relation to meals, retained undigested food, pain, nausea, the character of the material, bowel function, weight change, pregnancy possibility and exposure to drugs or ethanol. Delayed large-volume vomiting of food with weight loss suggests retention, but does not distinguish gastric outlet obstruction from impaired emptying by itself. Early postprandial discomfort, haematemesis or an abdominal mass changes the investigation. Bilious vomiting with distension and failure to pass stool raises concern for gastrointestinal obstruction. Headache, visual disturbance or focal neurological signs directs attention beyond the stomach; kidney disease, metabolic disturbances and pregnancy are also possible causes. None can be chosen as the diagnosis from the short source question alone.^[ref]

An 1867 physician could already distinguish suspected gastric ulcer, chronic gastritis, cancer, obstruction near the pylorus, pregnancy-related vomiting, uraemia and “sympathetic” vomiting accompanying disease elsewhere. The therapeutic reasoning was to remove a provoking dietary or medicinal cause, adapt food to what could be retained, investigate an obstructive or destructive lesion and address the associated systemic disease. Symptom suppression alone could conceal continued starvation. A 1867 digest reproduces an account of opium controlling vomiting in advanced consumption. It establishes an example of period palliation, not proof of cure and not a general prescription for chronic vomiting.^[ref]

Modern investigations are chosen by that differential: examination and appropriate blood tests for depletion or systemic disease, a pregnancy test where relevant, endoscopy for a suspected upper digestive lesion, and imaging when gastrointestinal obstruction is possible. Gastroparesis specifically means delayed gastric emptying without mechanical obstruction. After excluding obstruction, demonstrate abnormal emptying rather than diagnosing it from vomiting alone. A standardized gastric emptying scintigraphy follows a labelled meal with a gamma camera; serial measurements test how much remains in the stomach. This apparatus addresses a physiological question that simple inspection of vomited food cannot answer.^[ref]

Treatment then branches with the diagnosis. Obstruction needs decompression and treatment of the obstructing lesion; escalating an antiemetic does not remove it. A confirmed peptic ulcer may require Helicobacter pylori eradication, proton pump inhibitor treatment and withdrawal of an ulcer-provoking nonsteroidal anti-inflammatory drug where possible. A suspected malignant lesion needs tissue diagnosis and appropriate specialist treatment.^[ref] In confirmed gastroparesis, smaller suitable meals, nutritional planning, correction of a contributing diabetes problem and selected prokinetic or antiemetic treatment have distinct purposes: an antiemetic may reduce nausea without accelerating gastric emptying. Persistent nutritional failure may require feeding beyond the stomach.^[ref]

Medication-induced vomiting, metabolic disease, pregnancy-related illness and central causes require their own treatment pathways. Fluid and electrolyte losses need assessment and correction throughout. Reassess intake, weight and function as well as the frequency of vomiting. If no structural or metabolic explanation is established, investigate the relevant disorder of motility or gut–brain interaction on positive criteria; “nothing found yet” does not justify either a fabricated diagnosis or a dismissal of the symptom.
