Treatment Of Delirium

Treatment of delirium involves close monitoring of the vital signs and support of the metabolism while removing toxins that may be underlying the condition.

Here are two examples

1. For instance, consider a 25-year old man who is a known diabetic who has just finished a strenuous 3 hour hike without taking the time to have a snack. He had taken the normal morning insulin dose, and blood tests now confirmed low blood sugar (hypoglycemia).

This patient will likely recover very quickly from his delirium following glucose injections and a carbohydrate meal.

2. On the other hand an elderly woman who was picked up by police for jaywalking and was noted to be in a delirium, was found to be extremely hypothyroid when blood tests were taken. Her thyroid gland does not produce enough thyroid hormone and she will need to take replacement thyroid hormones for the rest of her life. In her case a few days of thyroid replacement are needed for the thyroid hormones to work and for her delirium to respond. However, this woman will be able to leave the hospital on thyroid hormone replacement, when her delirium had disappeared.

Treatment is directed against the underlying cause. Infection has to be treated with antibiotics, brain lesions may have to take time to heal in case of a stroke. On the other hand fast action may be needed in the case of an ischemic stroke where swift treatment with tissue plasminogen activator may be able to reopen a clogged artery and allow normal blood flow again to the affected brain area.

Every situation has to be treated individually and appropriately.

Treatment Of Delirium (Missing Hormones Can Cause Delirium)

Drugs used to treat delirium

The psychiatrist will use a number of different drugs to control difficult situations where a psychiatric condition is the reason for the delirium. As these patients are usually in the elderly age group the function of the kidneys and liver as the major drug eliminiation organs is slowed down compared to earlier in life. According to Dr. Marie Geizer (assistant professor of psychiatry at UBC, Ref. 16) this means that the physician has to be more careful about the dosages used. Going “low and slow” is the guiding principle. It is best to use one medication at a time. Here are a few comments regarding some of the more common psychotropic drugs used.

Drugs used for delirium treatment

Name of drug: Effect on the patient:
Neuroleptic drugs (haloperidol, loxapine, riperidone, chlorpromazine etc.) Used for acute psychosis with destructive behavior for rapid tranquilization. *SE: muscle rigidity, tardive dyskinesia
Anticonvulsants (carbamazepine, gabapentin) Used for toning down agression. SE: falls, sedation
Benzodiazepines (alprazolan, chlordiazepoxide,oxazepam, lorazepam) The shorter acting ones are better as they do not accumulate as much. SE: confusion, falls, sedation, urinary incontinence.
Antidepressants (trazodone, fluoxetine, paroxetine, venlaflaxine, etc.) For depression. SE: drug interactions have to be watched for, cardiotoxic side effects also
*SE = side-effect

 

These are only a few examples of the more frequently used drugs in the elderly who are having delirium problems. Benzodiazepines are the most abused drugs by the nursing personnel. The doctor will often leave a “prn dose” for benzodiazepines in case of agitation. The nurse is then entitled to use his/her own judgement in administering this drug when it seems indicated. However, when several of these doses are administered, withdrawal symptoms may present as “agitation” and this may be treated again with more benzodiazepines. The patient, particularly when frail, may get oversedated, fall and fracture a hip. This happens not infrequently in nursing homes, not with the intent to do so, but it happens nevertheless.

Treatment without the use of drugs

Geriatricians (physicians who specialize in the medical needs of the elderly) tell us that one should always attempt to use non-drug methods to treat symptoms first. Agitation can often be tackled by isolating the patient in a quiet room with soothing background music. Family can get more involved including grandchildren, when it is safe to do so. This social interaction changes the scene. Walking with the patient to “abreact” anger and frustrations can be helpful. It may require more staffing, which goes against the movement to cut back hospital budgets…

Detoxification

Books like “Breakthrough” (Ref.17) by Suzanne Somers have reviewed newer insights of antiaging medicine. This points out the importance of detoxifying the body from heavy metals like mercury, lead and cadmium. Many cases of delirium or dementia may in part be due to heavy metal poisoning. Hormone levels should be carefully checked to ensure that they are in balance.

When detoxification has been done, it is important to build up the metabolism by nutritional supplements.
