Case
Case No
No 11
History:
30 year old male standing in the middle of traffic, in a
downtown street.
A police officer offers to help the subject. The subject
seems to ignore to officer. The subject punches the
officer, when touched. The subject and the officer
struggle, and the subject is restrained.
The subject is brought to the hospital by the police for
medical clearance.
2

Case
Case No
No 11
Diagnosis:
Hypoglycemia
Diabetes mellitus
The subject’s mental status returns to normal after
receiving sugar in the emergency department. The
subject apologizes to the officer. No charges are
brought.
Graham v. Connor: Graham was suffering from
hypoglycemia. Officers believed he was drunk, and
refused to give him some sugar.
3

Case
Case No
No 22
30 year old female who is found agitated in a
street by the police.
EMS is called by the police. The subject is
brought to the emergency department for
confusion and hallucinations. She is cleared by
the medical resident despite a low-grade fever
(100.6 °F). The psychiatrist diagnoses a
delusional disorder, calms her down with oral
Haldol. The patient is discharged with a followup appointment.
4

Case
Case No
No 22
Three hours later, EMS brings her back for a
more severe agitation. She is given an injection
of Haldol.

Then, the vital signs:
Heart rate: 100
Blood pressure: 90/50
SaO2: 75% (normal > 95%)
5

Case
Case No
No 22
Chest X-ray: lobar pneumonia
Diagnosis:
Pneumonia (Streptococcus pneumoniae)
Septicemia
Septic shock
The patient was intubated in the emergency
department, and admitted to the intensive care unit. She
was given high doses antibiotics, but died 6 hours later.
6

Case
Case No
No 33
30 year old male arrested for selling
drugs.
He is brought to the emergency department for
medical clearance.
No prior medical history.

7

Case
Case No
No 33
Vital signs:
HR 140
BP 220/130
RR 28
T 103.2
Patient is very agitated. No other findings in the
physical exam.
8

Case
Case No
No 33
The patient now admits to swallowing several
bags of cocaine approximately 3 hours ago,
when he was arrested.
The patient receives nitroglycerin and
benzodiazepines, activated charcoal and
polyethylene glycol. The patient subsequently
develops
generalized
seizure
activity,
increasing hyperthermia, rhabdomyolysis, and
intracranial hemorrhage. He expires 24 hours
after admission.

Combination of
of Drugs
Drugs
In a large London hospital A&E department,
50% of the patients who had taken Ecstasy also
took
another
illicit
substance,
mainly
amphetamines and cocaine.
“The more serious complications of delirium,
seizures, and profound unconsciousness
(coma) were commoner when MDMA was used
in combination with other substances.”
(Williams, J Accid Emerg Med 1998)
35

Delirium
Delirium
Definition:
Acute change in mental status characterized by
impairment of attention.
Diagnostic Criteria for Delirium (as defined by DSM-IV)
A.Disturbance of consciousness (i.e., reduced clarity of awareness
of environment) with reduced ability to focus, sustain, or shift
attention.
B.A change in cognition (such as memory deficit, disorientation,
language disturbance) or the development of a perceptual
disturbance that is not better accounted for by a preexisting,
established, or evolving dementia.
C.The disturbance develops over a short period of time (usually
hours to days) and tends to fluctuate during the course of the day.

Definition:

Suffocation
Five types:
►

Depletion or displacement of oxygen and
carbon dioxide accumulation (e.g., sealed
container)

►

Smothering (obstruction of the nose and mouth --

e.g., plastic bag)
► Choke (obstruction of the internal airway by a
foreign object)
► Compression asphyxia (breathing hindered by
external chest compression)
► Laryngeal edema (e.g., allergy)

Kornblum (J Forensic Sci 1991):
Cause of death:

► Gunshot wounds - 3 cases
► Heart disease and Taser shock - 1 case
► Undetermined - 1 case
“The conclusion reached after evaluation of these cases
is that the Taser in and of itself does not cause death,
although it may have contributed to death in one
case.”

Speech is perhaps the most sensitive indicator in
differentiating between organic and psychiatric disease.
Patients with an organic alteration of mental status
generally have globally slowed speech patterns. There
are often problems with articulation, particularly in toxicmetabolic encephalopathies. Speech that is rapid, well
articulated, and well enunciated indicates that the vast
majority of the nervous system is functioning normally.
Even patients with severe psychiatric disorders often
speak rapidly, clearly, and without any obvious
hesitation.

Emergency Medicine, 1997)
