Anxiety, pain, and delirium are common in intensive care patients
and may be due any one of or combinations of the following factors:
disorientation, medications, or the underlying disease. While anxiety
can often be relieved by compassionate staff, agitation and delirium
can result in patient actions that put them at risk for falls, dislodgement
of medical devices, or disruption of wound dressings and incisions.
Appropriate management of these problems requires early identification,
differentiation among the potential causes, and appropriate treatment.
