Rationale for PACT
• High mortality after OHCA resuscitation
• Post Cardiac Arrest Syndrome
• Hospital survival rates vary
• E.g. 25%-30% locally vs. 50-60% in US
and Europe
• Local data shows care is not standardized
• Studies from elsewhere show improved
survival with champions and a standardized,
multi-faceted approach
3
Barriers
• Process concerns due to low volume of
OHCA
• Lack of a standardized approach
• Difficulty gaining experience
• The disjointed patient journey
• Access to specialized services
– (ICU, PCI, EP)
4
Post Arrest Consult Team
(PACT)
• Building on other Centres of Excellence
models
– Trauma, stroke, STEMI etc
• Building on the CCRT model
– Dedicated consult service of RN/RT/MD to
assist MRPs and primary nurses with
complex/high risk patients
5
Post Arrest Consult Team
(PACT)
• Guidelines inspired
• Evidence based
• Standardized clinical pathways
6
PACT Process
7
PACT Activation
• Single page PACT activation through locating
• Automated pre-hospital alert to PACT RN text
pager from upload of electronic ambulance
call report from Toronto EMS
• MDs will have cell phone/pager registered
with communications with call schedule
• RNs will have a PACT text pager which is
passed on to the PACT RN on call
• We will be tracking activation rates and
missed cases
8
Goal directed gas exchange and
hemodynamics
• Hyperoxia is bad
– minimize FiO2 for oxygen saturation ≥ 94%
• Hypocarbia is bad
– ventilate to ETC02 of 35-40 mmHG or PaCO2
levels of 40-45 mmHG
• Hypotension is bad
– MAP goal specified in pre-printed order set
• Best evidence suggests these are urgent
issues
9
Therapeutic hypothermia
Where PACT can have an IMPACT
• Cooling more eligible patients
• Appropriate core temperature monitoring
• Facilitating rapid decline in temperature
through the “danger zone” (quickly to 33.5)
– Proper placement/replacement of ice bags
– RAPID infusion of cold saline
– Shivering prevention/treatment
• Encouraging aggressive sedation, analgesia and
paralytic (PRN) as per hospital protocol
10
Therapeutic hypothermia
Where PACT can have an IMPACT
• Use of the trouble-shooting checklist
when cooling rates are too slow
11
Be aware of potential complications
during induction of hypothermia
• Shivering
– Will slow cooling
– Increase in metabolic rate and oxygen
demand
• Volume depletion
• Electrolyte abnormalities
– Hypokalemia, Hypomagnesemia,
Hypophospatemia
•12 Glucose resistance

PACT MD
Roles and Responsibilities
16
PACT MD
• 24-hour availability.
• In house M-F 9-5 with callback ASAP
and bedside assessment ASAP with a
target of within 15 minutes of consult.
• Home call for telephone consult afterhours with discretionary bedside
assessment
• For the ICU physicians call schedule
synchronized with ICU call
17
PACT MD
• Interaction with the PACT RN modeled after the
CCRT
– PACT RN will discuss case details, clinical
assessment and plan with the PACT MD after
initial contact with the patient is made
– A collaborative plan with the PACT RN will be
determined
– Similar to a resident to staff exchange
• PACT MD will provide “suggest” orders as needed
and discuss them immediately with the MRP or their
delegate at the time of assessment
18
PACT MD
• Initial involvement directed towards items in
the PACT clinical pathways that are urgent
– Gas exchange and hemodynamic goals
– Trouble-shooting therapeutic hypothermia to
ensure goal temperature reached
– Need for urgent coronary reperfusion?
– Making appropriate sub-specialty consultations
– Encouraging delayed neuroprognostication
19
PACT MD
• Subsequent bedside follow-up daily
during acute phase of care
– Support maintenance of hypothermia
– Support safe, controlled re-warming at 24
hours
– Support neuroprognostication pathway
– EP involvement as per protocol
– Consider etiology in collaboration with
primary team
20
PACT MD
• Clinical note expected for each consult
• Detail clinical assessment and management
plan, highlighting the important features
related to the PACT clinical pathways
• Hand-over PACT patient consult list to oncoming PACT MD for continuity of follow-ups
• Sign-off from patients when acute post arrest
issues are resolved (~72 hours?)

PACT RN
Roles and Responsibilities
23
PACT RN
• 24 hour in-hospital presence for PACT
• Goal: Respond to page for consultation and attend
patient bedside as soon as possible to assist the
primary care team in the implementation of best
practices for the post-arrest patient
• PACT will only consult on out-of-hospital arrest
patients; requests for in-hospital post cardiac arrest
patients will be politely refused
24
PACT RN
 An advocate for the patient and an ambassador for the
PACT
• Communication with primary MD, ED RN’s and PACT
MD and the RT’s
• WILL NOT take over primary nursing responsibilities
 Review PACT eligibility
• OHCA
• Comatose (not responding to verbal commands)
• ROSC
25
The PACT RN as a Champion
• The PACT RN is expected to have the
greatest impact related to optimizing the
induction of therapeutic hypothermia
accurate temp measurement
surface cooling
sedation & analgesia
cold fluids-FAST
NMBA’s
26
Therapeutic Hypothermia
• SHSC Pre-printed Therapeutic
Hypothermia orders
27
TH Potential Concerns
 PACT TH Trouble Shooting Checklist
28
Cooling Equipment
• Pre-printed orders and quick
reference
• Ice (freezer)
• Cold fluids – saline
• zip lock bags
• Esophageal probe
– Guide for esophageal probe
placement
– Paper measuring tape
• Note ED does not have a
cooling blanket
29
The PACT RN as a Champion
The PACT RN will also play a major role
in assessing the patient with respect to
the other clinical pathways
• Goal directed gas exchange/
Hemodynamics
• 12-lead ECG-urgent PCI
• EPS
• Neuroprognostication
30
Hemodynamic Optimization
and Gas Exchange
 RT collaboration to help facilitate the gas exchange
targets

Minimize FiO2 to maintain O2 saturation of 94-96%

Ventilate ETCO2 to levels of 35 – 40 mmHg OR

Maintain PaCO2 levels of 40 – 45 mmHg

Maintain MAP goal specified in pre-printed order set
31
Coronary Angiography
Assessment
• Check to see if 12-lead ECG
completed by the attending team
– If not done, work with ED RN to
complete
• Review the ECG with the MRP in the
ED and/or PACT MD to determine
possible STEMI
• If possible STEMI, discuss activation of
Code STEMI protocol
• Follow up with primary care team after
patient returns from Cath Lab
32
Electrophysiologist
Assessment
• Collaborate with PACT MD / MRP to
call for Electrophysiologist consult
33
