Opiate Crisis
transplant.bc.ca
What makes this a Crisis?
• In US
– 2000-2014 overdose rate doubled
– 2015 further 15% increase
– Drug overdose overtakes firearms, MVC as
number 1 cause of accidental death
– Life expectancy dropped for < 65 years old

Why has this happened?
• In the US
– Initial rise in prescription of opioids
• 3 DRIVING FORCES
– Moral imperative for physicians to treat pain
and relieve suffering
» Access to pain management is a
fundamental right
– Perceived under-treatment of pain
“oligoanalgesia”
» Focus on adequate pain management,
linked to reimbursement
Weiner et al. Transplantation 2017;101:678-681
transplant.bc.ca
Why has this happened?
• Impact of Pharma marketing
– OxyContin
• $200 million in 2001
• 10 fold increase by 2002Weiner et al. Transplantation 2017
Dowell et al. JAMA 2017
transplant.bc.ca
Opioid Crisis
• Tracking of increased opiate prescriptions noted
• Out of proportion to documented amount of pain
– Increased scrutiny
» CDC guidelines
» Prescription monitoring
» More stringent laws on prescribing
Weiner et al. Transplantation 2017;101:678-681
transplant.bc.ca
What next?
• Opioid prescriptions fall
– 2015 16.6 million fewer than 2014
• Concern now is lack of access leading to
increased use of illicit opiates
– Heroin
– Fentanyl and others

Impact on Organ Donation
• Increased volume of missed opportunities?
Work load
• Inability to do proper MRR
follow up of missed cases
• “Donor fatigue”

Neurological Determination of Death
transplant.bc.ca
That afternoon …
• Shock – PEA x further 3 times
• Profound hypoxemia
– O2sats in 70% range for several hours
– Unresponsive to PEEP, recruitment attempts,
NO
• ECMO – on VV at 17:30
transplant.bc.ca
Patient transfer
• Patient moved to regional ECMO centre and
more stable
– Arrived early evening Day 0
– On Propofol overnight – dc 07:00 Day 1
– Weaned off vasopressors by Day 2
– AKI resolved by Day 2
– LFTs normalizing
– ECMO – decannulated Day 3 15:50
transplant.bc.ca
Neurological status
• On presentation
– Pupils fixed, dilated, no brainstem reflexes, no
response to painful stimuli
• After resuscitation
– Pupils no longer dilated or fixed, spontaneous resp
noted
• Further re-arrest x 3, profound hypoxemia, on ECMO
– Pupils fixed, no brainstem reflexes, no response to
painful stimuli throughout remainder of stay
transplant.bc.ca
Neurostatus
• CT on Day 0 – diffuse cerebral edema
• CT on Day 2 – diffuse edema with evolving
changes of hypodensities within basal ganglia
and white matter
– Compatible with severe anoxic brain injury
transplant.bc.ca
End of Life Discussions
• Very guarded prognosis from beginning
– Parents very interested in donation
• Day 4 post presentation
– 3 days without any sedation
• Propofol off 76 hrs
• Last Versed/Fentanyl 89 hrs
– On Fentanyl at 50 mic/hr x 2 hrs
– Midazolam at 10 mg/hr x 1 hr, 40 mins
• 22 hours off ECMO
transplant.bc.ca
Brain Death Assessment
• 13:30 Day 4
– No brainstem reflexes
– No response to painful stimuli
– No spontaneous resp on Apnea test
• 16 minutes
• PaCO2 40 to 74, pH in expected range
• Pronounced dead
• BC Transplant contacted and NDD management put in
motion
transplant.bc.ca
Next 24 hours
• Noted difficulty with recruitment maneuvers
• Question whether some spontaneous breathes
• With MRP present placed on T-piece and
occasional breathes noted @ ~ 08:30 Day 5
• Nuclear Med Brain Scan Day 5
– Flow to brain noted
transplant.bc.ca
Next 24 hours
• Discussion with family
– MRP and 2nd colleague both of opinion patient has had a severe
anoxic brain injury and no hope of recovery
– Family do not wish life support to be continued
– Agree to DCD
• Day 5, extubated at 20:08 –
– > 108 hrs off Propofol, 120 hours since Versed, Fentanyl and ~
129 hours post-event
– No resp noted
– Asystole at 20:15
– To OR for recovery at 20:21
• 2 kidneys, liver recovered.
transplant.bc.ca
Neurological Determination of Death of Overdose
• Challenge
– Uncertainty around what and how much taken
– Difficult to know when clearance sufficient
• Clinical assessment perhaps more to rule out
brain death
• Strongly consider ancillary testing
– Unclear how long to wait
– Don’t want to wait long
transplant.bc.ca
Summary
• Opiate Crisis continues
– organ donors
• Canadian study of regional impact
– Increase in high risk / Hep C
– Stress on resources
– Need to focus on MRR
– Challenge of NDD in OD setting

The Opiate Epidemic and Organ Donation
1. Opiate epidemic is a real crisis
increasing number of deaths
decrease in life expectancy
no solution as yet
2. Opiate epidemic and organ donation
Increase in volume of donors
Change in donors
- more “increased” risk donors
- increase in Hep C organs available
- potential underuse of these organs
Declaration of Brain Death a challenge
- use of ancillary testing suggested
