Functional Symptoms in Intensive Care: The Vicious Circle of Anxiety and Symptoms

Functional Symptoms in Pediatric Disease

Abstract

This chapter reviews the functional symptoms likely to be encountered in the pediatric critical care setting. Considering symptoms to be “functional” implies that a psychological or emotional state contributes to the symptom. Thus functional symptoms overlap with related terms such as “psychogenic,” “psychosomatic,” and “nonorganic” symptoms. Functional symptoms occur on a daily basis in the intensive care unit (ICU) when a child’s anxiety intensifies unpleasant symptoms. At the same time, unpleasant symptoms amplify anxiety. And if there is a vicious circle of anxiety and symptoms for the child, this is also exacerbated by a vicious circle of anxiety among the child, family, and staff. Symptoms during routine care, procedures, or crises in the ICU can be controlled by a combination of pharmacological and nonpharmacological strategies. Functional symptoms may mimic a life threatening condition, on rare occasions, requiring a timely diagnostic evaluation.
