: The current evidence examined suggests that the use of intranasal dexmedetomidine at appropriate doses may be associated with reduced postoperative pain and agitation without prolonging recovery time or increasing the risk of serious adverse events. Hydromorphone was reported in the included trials to be associated with better postoperative pain control than sufentanil, whereas remimazolam, although associated with reduced delirium incidence in some trials, did not influence the length of stay in the post-anesthesia care unit. Magnesium sulfate, although not significantly affecting the incidence of delirium, was associated with alleviation of postoperative symptoms such as pain and insomnia in adult patients. Ketamine, while commonly used for analgesic therapy, did not demonstrate a consistent association with delirium prevention and, in some studies, was associated with increased neuropsychiatric events. Further research is required to more precisely define optimal perioperative delirium prevention protocols.
