This combination warrants a grave prognosis and closely supervised treatment of both the pneumonia and the delirium tremens; recovery cannot be promised or ruled out from the diagnosis alone. The immediate conflict is that the agitation and sleeplessness of alcohol withdrawal call for effective control, while pneumonia reduces respiratory reserve. Excessive sedation can then worsen hypoventilation and aspiration, whereas uncontrolled delirium tremens can itself be life-threatening.

An historically reasoned 1864 approach would emphasise continuous nursing, a quiet environment, nourishment and fluids that the person could safely swallow, and repeated examination of the thorax and circulation. Suppressing a cough or inducing sleep would not demonstrate resolution of the pneumonia. The traditional strongly depleting approach to inflammation, including bloodletting and large doses of tartar emetic, would be especially hazardous in an exhausted person. Opium and alcoholic stimulation were debated contemporary remedies; escalating opium simply because sleep had not occurred could deepen respiratory depression. Period discussion of delirium tremens explicitly recognised that treatment response varied and that intercurrent disease altered the outlook.^[ref] These are historical treatment controversies, not present instructions to administer alcohol or opium.

Modern management is in hospital, with an appropriate level of observation and early critical-care assessment if breathing or consciousness deteriorates. Assess the airway, respiratory rate, oxygen saturation, blood pressure, temperature, blood glucose and electrolytes. Establish the severity and likely cause of the pneumonia, including possible aspiration; a chest radiograph and microbiological samples are used as indicated. Give timely antibiotics selected for the setting, severity, likely organisms and local resistance patterns. Provide oxygen therapy or more advanced respiratory support when indicated, while reassessing the response.^[ref]

Treat the delirium tremens using an appropriate benzodiazepine regimen with frequent reassessment; the respiratory illness makes skilled monitoring particularly important, rather than making untreated withdrawal acceptable. Provide thiamine, with the parenteral route when indicated by malnutrition or suspected Wernicke encephalopathy, and correct relevant deficiencies. Hypoglycaemia requires prompt treatment. Antipsychotics are not a replacement for treatment of the underlying alcohol withdrawal.^[ref]

Historically the absence of effective antibiotics made the additional pneumonia particularly ominous. Today the outlook depends on respiratory failure, sepsis, coexisting organ disease and treatment response. No severity findings, age or organ-function results are supplied, so neither a mortality percentage nor an inevitable fatal outcome follows. A poor result would also not, by itself, prove that a particular historical remedy caused or prevented death.
