Figure 6.1 Tracking the incidence of cocaine overdose deaths in Dade County, FL. Medicolegal investigations of the deaths were conducted by forensic pathologists. Forensic pathologists evaluated the scene environment and circumstances of death and autopsied the victim in order to determine the cause and manner of death. The circumstances of death and toxicology results were reviewed before classifying a death due to cocaine toxicity with or without preterminal delirium. There was a sharp increase in the incidence of cocaine-related and cocaine overdose cases with the arrival of crack cocaine in Dade County. The incidence of cocaine delirium victims is shown by year, from the first report in 1982.

This is a fair summary of the attractions offered to would-be volunteers. (Civilian investigators also frequently provide generous financial inducements to attract volunteers for their drug studies.) But our volunteers did not receive any additional privileges or compensation for participating in two or more different experiments. Subjects who had already experienced the delirium produced by BZ were often willing (or even offered) to repeat the experience two weeks later. Asked to put a price on a second consent, one man said 25. This willingness can hardly be attributed to the previously mentioned inducements, since they were already earned. 

The effect of a single bolus dose of midazolam before the end of sevoflurane anesthesia has been investigated in a double-blind, randomized, placebo-controlled trial in 40 children aged 2-7 years (33). Midazolam significantly reduced the incidence of delirium after anesthesia. However, when it was used for severe agitation, midazolam only reduced the severity of agitation without abolishing it. 

Cerebrospinal fluid examination and electroencephalography are not required routinely in the investigation of dementia. Lumbar puncture is indicated in suspected Creutzfeldt-Jakob disease or other forms of rapidly progressive dementia. Electroencephalography should be considered if delirium, frontotemporal dementia or Creutzfeldt-Jakob disease are possibilities. Electroencephalography may also be required in the assessment of associated seizure disorder in those with dementia. 

The first report of a psychotomimetic episode due to dlethylamlnoetl l benzllate In a human being was credited to Vojtechovsli (217) by Banshchikov and Stoliarov (216). This investigator had published In 1958 a case report on a female physician who had accidentally taken about 1.4 g of the benzllate. The woman experienced visual hallucinations and brief delirium. Intentional administrations of dlethylamlttoett l benzllate to human subjects had shown (218) chat the psychotomimetic state lasted for 4-12 h and was accompanied by a decrease in urinary excretion of 5-hydroxylndoleaceclc acid. These authors stated that... 

Psychiatric Mianserin has been investigated as a treatment for delirium [39 ]. However, in four elderly patients with dementia for 1.5-5 years, the addition of mianserin 30 mg/day to their existing dementia treatment resulted in acute delirium [40 ]. They recovered to their previous state when the mianserin was withdrawn.

The prevalence of delirium after the administration of dexmedetomidine 0.1-0.7 micrograms/kg/hour or morphine (10-70 micrograms/kg/hour) has been investigated in a double-blind, randomized, controlled trial in 306 patients, aged 60 years or older, undergoing cardiac surgery [51 ]. The prevalence of delirium was modestly higher with morphine (8.6% with dexmedetomidine 15% with morphine) and patients on morphine spent more days in hospital. 

Delirium has been attributed to accidental overdosage and subsequent withdrawal of baclofen [46 ]. The authors commented that the pathophysiology of the effect of baclofen in humans in producing psychotic symptoms during withdrawal states is unclear and warrants further investigation. 

Psychological The incidences of different types of emergence phenomena after intravenous ketamine, mean dose 1.15 mg/kg, for procedural sedation have been investigated in children [40 ]. Of 745 patients, 93 (13%) cried on awakening from sedation, of whom 84 were consoled by their parents. The rest were defined as having emergence delirium. Another seven children were... 

Cases are often complex, and your role is supporting the medics, not taking over management. When unsure, encourage them to investigate as they would a new patient, and treat for delirium first. 

Work closely with the medics to examine investigate for other causes of delirium... 

In another report, a 70-year-old depressed man with no significant medical illness developed auditory and visual hallucinations after 3 days of escitalopram treatment at 5 mg per day, continuing when citalopram was increased to 10 mg per day. Investigations, including cranial MRI were negative, his MMSE score was 23/30 and there was no evidence of either delirium or dementia. Following suspicion of drug-induced psychotic symptoms, escitalopram was tapered to 5 mg per day and ceased after which his psychotic symptoms abated [36 ].
