ICU PSYCHOSIS

ICU PSYCHOSIS

ICU Psychosis is a disorder in which patients in an intensive care unit (ICU) or the hospital setting may become delirious. They may experience hearing voices, paranoia, see things that are not there, become severely confused in time and place, become very distressed, even aggressive, etc. This condition is properly defined as “acute brain syndrome” which impairs intellectual functioning experienced by patients who are treated within a critical care unit. ICU psychosis is a form of acute brain failure. The factors that contribute to delirium include hypoxia (low blood oxygen), heart failure (inadequate cardiac output), dehydration, side effects of drugs, and infections.

SYMPTOMS

What causes psychosis? 

  1. Environmental causes
  • Sense of deprivation. Patients feel neglected as they are away from family and friends, and all that is familiar to him or her that gives comfort. 
  • Trouble sleeping. The noise with the hospital staff checking the vital signs, giving prescriptions, etc. 
  • Stress and lack of orientation. Patients may feel a loss to control their life. Patients’ lose track of time and date. 

     2. Medical Causes 

  • Side effects of prescriptions. The medications given to the patient may be new to the system of the patient.
  • Critical illness. The stress on the body during illnesses may trigger a variety of symptoms. 
  • Infections trigger toxins and fever in the body. 
  • Heart failure and Dehydration.

TREATMENT

It is determined that in every three patients, there is one patient who spends more than five days in an ICU that experiences some conditions or symptoms of a psychotic reaction. As the number of intensive care units and the patient population increases, the number of persons affected by this disorder relatively increases. Patients that are being transferred out of the ICU quickly than in years past; ICU psychosis is more common in areas such as the ordinary medical floor of the hospital or sometimes occurs after release from the hospital.

The ICU psychosis treatment varies depending on the cause(s). It involves many factors and issues that need to be resolved to mitigate the symptoms. One of the necessary steps is reviewing the patient’s medications. The doctor in charge of the patient collaboratively works with the pharmacist in evaluating the patient’s medications to identify whether it influences the delirium.

Support from loved ones, familiar objects, and comforting words may also help. Another major factor contributing to this condition is sleep deprivation. Therefore, providing a quiet and restful environment is a must to let the patient sleep and rest are essential. Also, by controlling the visitors time in stimulating the patients can help. Dehydration can be medicated by taking appropriate prescriptions. Heart failure needs treatment with digitalis or cardiac glycoside. Infections must be examined and treated properly. Antipsychotic agents with sedation may help as well. A common prescription used in the hospital setting in treating ICU psychosis of the patient is haloperidol or other medications for psychosis (antipsychotics).

It is necessary to understand that in saving lives in the uncertain environment, ICU psychosis sometimes may be worthy of the costs incurred for cutting edge, appropriate medical life-saving procedures.
