  Purpose

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.

Primary Outcome Measures:
  • Change in Altered Mental Status Score [ Time Frame: Assessed every five minutes, from enrollment until discharge from the emergency department, an expected average time of 4 hours ]
  • Change in Visual Analog Scale Pain Score [ Time Frame: Assessed every five minutes, from enrollment until discharge from the emergency department, an expected average time of 4 hours ]
  • Change in Serum Total Catecholamines [ Time Frame: Assessed every 30 minutes, from enrollment until discharge from the emergency department, an expected average time of 4 hours ]
    Serum dopamine, serum epinephrine, and serum norepinephrine.


Secondary Outcome Measures:
  • Length of Hospital Stay [ Time Frame: Assessed at time of discharge from the hospital, an expected average of 4 hours post enrollment. ]
  • Mortality [ Time Frame: Observed for 1 year post study enrollment ]
  • Complications [ Time Frame: Observed for 1 year post study enrollment ]
  • Change in Heart Rate [ Time Frame: Observed from time of enrollment until discharge from the emergency department, an expected average time of 4 hours ]
  • Change in Systolic Blood Pressure [ Time Frame: Observed from time of enrollment until discharge from the emergency department, an expected average time of 4 hours ]
  • Change in Mean Arterial Pressure [ Time Frame: Observed from time of enrollment until discharge from the emergency department, an expected average time of 4 hours ]
  • Disposition [ Time Frame: Assessed at discharge from the emergency department, an expected average of 4 hours post enrollment. ]
  • Change in Body Temperature [ Time Frame: Observed from time of enrollment until discharge from the emergency department, an expected average time of 4 hours ]
  • Change in end tidal carbon dioxide [ Time Frame: Assessed from time of enrollment until discharge from the emergency department, an expected average time of 4 hours ]
  • Change in Oxygen Saturation [ Time Frame: Observed from time of enrollment until discharge from the emergency department, an expected average time of 4 hours ]

Groups/Cohorts
Agitation Group
Patients that are evaluated to have an altered mental status score greater than 1 will be enrolled in the Agitation Group.
Pain Group
Patients that report severe pain secondary to a long bone fracture or dislocation and report a visual analog scale pain score greater than 7 will be enrolled in the Pain Group.

Detailed Description:
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.
