The purpose of this project is to determine the levels of stress biomarkers associated with
severe pain, agitation from intoxication or psychosis, and excited delirium at various
levels of the disease in order to compare them to pre-clinical models of law enforcement
encounters. We hypothesize that the serum catecholamines and markers of metabolic acidosis
will worsen with the duration and severity of agitation among agitated patients and will not
worsen among patients with severe pain who are not agitated.
Specific Aims
- To assess the prevalence of patients undergoing treatment for agitation from any cause
requiring restraint or sedation.
- To assess the prevalence of excited delirium in the emergency department.
- To determine the difference in serum total catecholamines, serum dopamine, serum
epinephrine, serum norepinephrine, heart rate, systolic blood pressure, mean arterial
pressure, mortality, and disposition among patients with agitation requiring restraint,
including excited delirium and patients with severe pain from extremity fractures.
- To describe changes in stress biomarkers among patients with changing levels of
agitation as determined by the Altered Mental Status scale.

In this study, we propose to study Emergency Department patients under physiologic stress
from severe pain, agitation, drug overdose, and excited delirium in order to compare markers
of acidosis in patients at risk for unexplained-in-custody-death (UICD) in order to
determine the relationship of these markers to what has been found in simulated law
enforcement encounters. This information will help clarify the levels of stress associated
with arrest and restraint conditions, allowing us to determine what aspects and levels of
stress may be associated with the fatal mechanisms of UICD, and to identify markers that
would inform death investigators of the mechanism of UICD. At the conclusion of this
project, we will be able to report details explaining the relationship of the physiologic
and metabolic effects of stress from restraint in excited delirium to other peri-arrest
conditions and our previous work in simulated law enforcement encounters.
