Review Case Reports
Adjunctive haloperidol prophylaxis reduces postoperative delirium severity and duration in at-risk elderly patients.
Delirium is a potentially life-threatening syndrome that is particularly common in elderly hospitalized patients, especially those with preexisting neurologic disorders. Nonpharmacological tactics can reduce the incidence and severity of delirium in acute care settings and antipsychotic drugs are widely used to treat established delirium. More effective preventive strategies could notably impact morbidity, mortality, and health care costs. ⋯ Adjunctive low-dose haloperidol prophylaxis reduces delirium severity, duration, and subsequent hospitalization length in elderly at-risk patients. Further study is needed to determine the optimal pharmacological approach, combination with nonpharmacological strategies, and generalizability to other settings.
