DNR Decision
What does the DNR decision mean to the family?
•
•
•
•
•
No Chest Compressions?
No Shock?
No Medications?
No Labs?
No Fluids?
“Do not harm?” or “Do not treat?”
DNR Decision
What does the DNR decision mean to the healthcare team?
•
Routine decision in the Critical Care Unit
•
Interpreting DNR decision varies by hospital, unit,
physician, nurse
Donation Decision
Understanding the donation option clinically:
• Maintaining blood pressure
• Normalizing electrolytes
• Managing oxygenation and organ perfusion
• Balancing Intake and Output
• Assessing brain death accurately
How can a family give the gift of life when the organs
are not preserved for transplantation?
Balancing DNR and Donation
Devastating Traumatic Brain Injury (TBI)
+ Overall Clinical Deterioration
+ DNR Decision by Next-of-Kin
+ Fatal Diagnosis (Brain Death?)
“Step Down” in clinical management?
- or -
Maintain clinical management and prevent
secondary injury to organs?

Physician Progress Note: “Pt. appears brain dead.
Discussed grave prognosis with family. Neurosurgery
to evaluate.”

Family Conference with Physician
Case Study
5 days post-admission:
Data: GCS=3, BP=90/50, H/H=8/25, UO=300mL/hr,
pH=7.28, Na=180, Cr=2.0/BUN=30, ICP=60
Brain Death Note #1
Neurosurgery Progress Note: “Attempted apnea test. Pt did
not breathe for 2 minutes but became unstable. Apnea test
aborted. PT is brain dead, based on clinical exam. Discussed
with family. Will require brain death confirmatory test. Second
brain death note to follow.”
Management: IV fluids, sedation, high dose
Levophed and Neosynephrine
Assessing the Balancing Act
Admission:
Data: post-craniectomy, GCS=6, BP=140/80, H/H=14/38,
UO=200mL/hr, pH=7.4, Na=135, Cr=0.8/BUN=10, ICP=15
5 Days Post-Admission:
Data: GCS=3, BP=90/50, H/H=8/25, UO=300mL/hr,
pH=7.28, Na=180, Cr=2.0/BUN=30, ICP=60
Does our patient data reflect preservation of the
family’s donation option?
Assessing the Balancing Act
Devastating TBI
+ Overall Clinical Deterioration
+ DNR Decision
+ Fatal Diagnosis (Brain Death)
Maintain clinical management and
prevent secondary injury to organs.
Pathophysiology of
Traumatic Brain Injury
Physiologic collapse frequently accompanies TBI:
Hypotension
Endocrine Dysfunction
Pulmonary Dysfunction
Hematologic Dysfunction
Pathophysiology of
Traumatic Brain Injury
Hypotension:
• “Autonomic storms”
• Systemic and pulmonary vasoconstriction
• Associated with herniation
• Can recur unpredictably
• Smooth muscle ATP depleted = vasomotor hypotension
• Diuretics
Pathophysiology of
Traumatic Brain Injury
Hypotension:
•
•
•
•
•
Closely monitor Intake and Output – DI?
Anticipate BP spike followed by BP drop
Consider Fluid Resuscitation
Titrate Vasopressors
Consider Hormone replacement – T4
Pathophysiology of
Traumatic Brain Injury
Endocrine Dysfunction:
• Hypothalamic injury -> pituitary dysfunction
• Thyroid dysfunction
– T4 Infusion
• Glycemic control disrupted
– Insulin infusion
Pathophysiology of
Traumatic Brain Injury
Endocrine Dysfunction:
• Relative deficiency of corticosteroids
– Solumedrol Infusion
• Reduction of Antidiuretic Hormone / Diabetes Insipidous
– ADH, Vasopressin Infusion
Pathophysiology of
Traumatic Brain Injury
Pulmonary Dysfunction:
• Neurogenic pulmonary edema
– Multifactorial
– Systemic hypertension + LV dysfunction
• Primary pneumatocyte dysfunction
Pathophysiology of
Traumatic Brain Injury
Pulmonary Dysfunction:
• Iatrogenic injury due to aggressive resuscitation
• Exacerbated by intubation, aspiration, atelectasis
• Concurrent blunt lung injury common
– Parenchymal injury problematic in immunosuppressed
recipients
Pathophysiology of
Traumatic Brain Injury
Hematologic Dysfunction:
• Thrombocytopenia
– Platelets as needed
• Coagulopathy/DIC
– FFP / Cryo as needed
• Hypothermia
– Keep them warm!
What Are Traumatic
Brain Injury Guidelines?
Hospital approved guidelines
for treating patients with
Traumatic Brain Injury
23
What Are Traumatic
Brain Injury Guidelines?
Prevent secondary injury, even with grave prognosis
• Secondary injury includes other organs, as well as the
brain
Maintain Organ Perfusion
• Volume Load
• Monitor & Maintain adequate CVP, MAP
• Oxygenation
24
What Are Traumatic
Brain Injury Guidelines?
Continuous fluid resuscitation
• Correct electrolyte abnormalities
Rule of 100’s:
• SBP >100mm Hg
• U/O >100ml/hr
• PaO2 >100
25
Why Implement
TBI Guidelines?
• Ensure consistent management of the critically ill patient
• Maintain homeostasis for accurate brain death
assessment
• Prevent “secondary injury” to organs, even with grave
prognosis
• Provide a clinical bridge between determination of brain
death and family’s decision on donation
26
Aggressive Organ Donor Management Significantly
Increases the Number of Organs Available for
Transplantation
(Salim et al. J Trauma 2005; 58: 991-994)
• LAC + USC Standardized organ donor management
protocol
• Before-after study (January 1998) of ADM institution
– January 1995-December 2002
LAC+USC Study
(Salim et al. J Trauma 2005; 58: 991-994)
• Vasopressors if MAP <70.
– Dopamine
– Levophed
– Vasopressin
• Hormones for maximal vasopressors.
– Insulin
– Solumedrol
– T4
LAC+USC Study
(Salim et al. J Trauma 2005; 58: 991-994)
Results
• 878 patients referred, 460 (53.4%) patients potential organ
donors and 161 (34.3%) actual donors.
• # patients referred increased 57%
• # of potential donors increased 19%
• # of actual donors increased 82%
• # of patients lost to cardiovascular collapse decreased 87%
• # of organs recovered increased 71%

Summary
• Critical care teams can honor the DNR decision while
preserving the option of donation.
• Pathophysiology of TBI can be anticipated and treated.
• TBI Guidelines can be implemented to prevent “step
down” in clinical management, and preserve the family’s
donation option.
