ICU psychosis is a form of delusion experienced by hospitalized patients, causing anxiety, hallucinations, and paranoia. It can last up to two weeks and is caused by various factors such as an unfamiliar environment, medical reasons, and medication reactions. Treatment aims to prevent harm to the patient and includes familiar objects, medication review, and ensuring adequate rest.
A form of delusion, intensive care unit psychosis is an episode experienced by a hospitalized patient. During ICU psychosis, a patient will become momentarily psychotic and experience a variety of symptoms. Patients will generally experience anxiety, hallucinations and paranoia, among other symptoms. After experiencing a severe episode of delirium, the patient will most likely have no memory of it. Treatment for psychosis in the ICU varies, but generally aims to keep the patient from harming themselves.
Also known as acute cerebral insufficiency or sunset, ICU psychosis can last up to a day or even two weeks with different symptoms, usually worse at night. A patient may suddenly experience psychosis and become restless, agitated and excited. Furthermore, a hospitalized person may suffer from nightmares, delusions and disorientation. The person’s level of consciousness usually varies and can include violent behavior. About a third of patients who spend at least five days in intensive care will experience some type of psychotic episode.
ICU psychosis is caused by a number of factors. In general, the patient’s environment in the hospital can play a role. In a hospital, a patient is typically placed in an unfamiliar room, and if the room has no windows, the patient may not be able to tell day from night, causing havoc with biorhythms. Being placed in intensive care can also cause a high level of anxiety, as a person may not have any control over their life. Constant monitoring and meeting with medical personnel can disturb patients and lead to sensory overload.
A person in intensive care may also suffer from psychosis for medical reasons. The stress of the patient’s illness or reactions to medications can lead to delirium. While in hospital, a person may also develop an infection, which causes fever and toxins in the body. Dehydration and electrolyte imbalances, as well as a high level of liver enzymes, are other factors that can lead to delirium.
It is important to ensure that patients with psychosis in the ICU do not harm themselves. Allowing the patient’s family to be nearby can help when the patient becomes agitated, as can placing familiar objects around him. It is also important to ensure that the patient’s medications are not causing delirium. Finally, it is important to ensure that the patient does not become sleep deprived and to place him in an environment where he can get enough rest. In severe cases, when a patient becomes so out of control and no other measures work, they may need to be restrained or treated with medication to keep them from getting hurt.
