CCS 2016 Guideline: Optimal Care of the Post Arrest Patient
Slide 3-

INTRODUCTION
Slide 4-

Purpose: To provide a practical yet comprehensive approach to survivors of cardiac arrest for a Canadian setting Emphasize the concept of a “Care bundle” encompassing 4 key aspects of care for the post arrest patient: 1. Targeted temperature management (TTM) 2. Coronary angiography and revascularization 3. Critical care management 4. Regionalization of post-arrest care Topics NOT covered: Mechanical cardiac support Neuroprognostication/end of life decision making Overview of the 2016 Update

Practical Use of Targeted Temperature Management
Slide 8-

Practical Use of Targeted Temperature Management We define TTM as a strategy of intentional temperature management of a post-arrest patient comprising active patient cooling, subsequent rewarming, and extended fever control We define “comatose” or “unresponsiveness” in post-arrest patients as an absence of purposeful response to verbal commands

Circulation. 2015;132[suppl 1]:S84-S145 Which Patient Populations Benefit from TTM? Resuscitation. 2015;95:202-22
Slide 11-

Too few patients studied (total n = 350 patients) HACA n = 273 Bernard n = 77 Large difference in intensive care compared with today HACA: 20% received thrombolysis Bernard: 3 patients received thrombolysis; 3 patients underwent angioplasty High risk of bias No standardized protocol for withdrawal of care Concerns about the 2002 Trials

Slide 13-

Recommendation: We recommend that TTM be used in unresponsive OHCA survivors with an initial shockable rhythm following return of spontaneous circulation (ROSC) (Strong Recommendation, Low Quality Evidence). Values and Preferences: Despite the overall low quality of evidence we considered the low NNT, ease of administration and low cost of TTM for this strong recommendation. Recommendation
Slide 14-

2. OHCA with an Initial Non - Shockable Rhythm 3. IHCA with any Initial Rhythm Which Patient Populations Benefit from TTM?
Slide 15-

Recommendation: We suggest TTM be used in unresponsive OHCA survivors with an initial non-shockable rhythm following ROSC (Conditional Recommendation, Very Low Quality Evidence). Values and Preferences: Although the evidence base is inconclusive, we valued the potential benefit and apparent lack of harm of TTM in this patient group. Practical Tip: Patients with an initial shockable rhythm have improved rates of survival with a good neurological outcome compared to those with an initial non-shockable rhythm. It is important to carefully consider patient age, comorbidities, and the resuscitation history when determining the subset of patients with non-shockable rhythms who are more likely to benefit from TTM. In the highest quality study, patients who benefited from TTM in this subgroup had age <75, a witnessed arrest, or ROSC <40 min. Recommendation
Slide 16-

Recommendation: We suggest that TTM be considered in unresponsive survivors of IHCA with any rhythm following ROSC (Conditional Recommendation, Very Low Quality Evidence). Values and Preferences: As there is no high-quality evidence to support or disprove the use of TTM in this patient population, the potential benefit and lack of harm influenced our recommendation. Recommendation
Slide 17-

Nielsen, et al. NEJM. 2013;369:2197-206. Is There a Preferred Temperature When Using TTM? N = 939 comatose survivors of OHCA Shockable and non-shockable rhythms Primary endpoint was all-cause mortality No difference between 33°C versus 36°C
Slide 18-

Well controlled temperature targets Study population more closely resembling clinical practice “Modern” ICU/CICU care Predefined protocols for withdrawal of care Designed as a superiority trial Higher bystander CPR rate Time between ROSC and onset of cooling was delayed Rate of cooling was not standardized Rewarming was too rapid TTM Trial Pros & Cons
Slide 19-

Recommendation: We recommend that a temperature between 33 and 36°C, inclusively, be selected and maintained for patients undergoing TTM (Strong Recommendation, Moderate Quality Evidence). Values and Preferences: We acknowledge that the evidence does not conclusively favour a temperature of either 33°C or 36°C, so practitioners may use a temperature range. We favoured 33°C rather than 32°C as the lower bound of our recommended temperature range based on the current primary literature. Practical Tip: The chosen target temperature should ideally be maintained during the active temperature management phase. Excessive bradycardia or hemodynamic instability at 33°C may be improved by raising the target temperature to up to 36°C. Recommendation
Slide 20-

What is the Benefit of Pre-hospital use of TTM? Seven RCTs studied the effect of initiating TTM in the pre-hospital setting on favourable neurologic outcome or survival only at discharge. N = 1359 cooled with chilled IV fluids Did not improve survival or neurological status at hospital discharge Increased hypoxemia and radiographic pulmonary edema in the first 24 hrs JAMA 2014;311:42-52.
Slide 21-

Recommendation: We do not recommend the use of chilled intravenous fluids for pre-hospital cooling after ROSC (Strong Recommendation, Moderate Quality Evidence). Practical Tip: Given the lack of evidence, the risk vs. benefit of initiating TTM should be individualized when long transport times are anticipated. There is insufficient evidence to provide a recommendation regarding other methods of pre-hospital cooling. Recommendation
Slide 22-

What is the Optimal Method of Delivering TTM? Recommendation: We suggest that either surface cooling or intravascular cooling techniques may be utilized to induce and maintain TTM. (Conditional Recommendation, Low Quality Evidence). Practical Tip: Both surface and intravascular cooling devices have their own unique advantages and disadvantages. The choice of method should take into account patient variables, equipment availability, and institutional expertise.
Slide 23-

What is the Optimal Method of Delivering TTM? Recommendation: We suggest that the cooling temperature selected for TTM should be maintained for at least 24 hours. (Conditional Recommendation, Very Low Quality Evidence). Recommendation: We suggest TTM may be continued beyond 24 hours from ROSC to prevent fever (temperature > 37.5°C) (Conditional Recommendation, Very Low Quality Evidence). Values and Preferences: Despite the controversy as to whether the presence of fever is a cause or consequence of cerebral anoxia, we value the potential benefit and low risk of continuing TTM beyond 24 hours for this recommendation.

Angiography and Revascularization Following OHCA
Slide 25-

Ischemic heart disease is the most frequent cause of OHCA, with acute coronary occlusion causing pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF) in many cases. Prompt identification and appropriate management of culprit coronary artery disease (CAD) is therefore important. Case series demonstrate an association between routine diagnostic coronary angiography and PCI in OHCA survivors with improved survival. Introduction
Slide 26-

The presence of ST-segment elevation in OHCA survivors is associated with underlying culprit CAD. Comatose OHCA survivors with STEMI have increased long-term mortality relative to other STEMI patients but they do benefit from successful PPCI. Retrospective data suggests fibrinolysis and PPCI are associated with improved rates of hospital discharge and neurological recovery amongst survivors of OHCA, with a suggestion that PPCI may be superior to fibrinolysis. Role of Coronary Angiography in OHCA Patients with STEMI
Slide 27-

We recommend that in OHCA patients with STEMI, immediate angiography and PPCI be considered when timely access to cardiac catheterization is feasible. (Strong Recommendation, Moderate Quality of Evidence) We recommend fibrinolysis for OHCA patients with STEMI if timely PPCI cannot be performed and there are no absolute contraindications to its use. (Strong Recommendation, Low Quality Evidence) We recommend against fibrinolysis as an adjunctive resuscitative agent for OHCA patients. (Strong Recommendation, Moderate Quality Evidence) Recommendations
Slide 28-

Clinical outcomes after routine angiography in patients without STEMI on presentation are mixed, with some studies demonstrating improved survival with routine angiography, and others demonstrating no benefit. A strategy of routine angiography for all unselected OHCA survivors has less benefit compared to restricting angiography for selected OHCA patients post-ROSC. Role of Coronary Angiography in OHCA Survivors Without STEMI
Slide 29-

We suggest urgent angiography ± PCI be performed in patients without ST-elevation following OHCA if there is a high suspicion for ACS and no major comorbidities or contraindications to invasive angiography. (Conditional Recommendation, Moderate Quality Evidence) Recommendation
Slide 30-

The need for urgent diagnostic coronary angiography +/-PCI in OHCA survivors without STEMI should incorporate the likelihood of benefit from acute coronary revascularization and the perceived risk of the procedure. Neurologic status should not be regarded as a contraindication to early invasive assessment following OHCA. No randomized trial has defined the optimal timing for angiography amongst OHCA survivors without STEMI, but we believe it is reasonable to proceed with angiography for OHCA survivors without STEMI who have a suspected cardiac etiology as soon as it is clinically feasible. Practical Tips:
Slide 31-

Retrospective data suggests an acute culprit coronary occlusion may be found in up to 50-70% of post-arrest cases, supporting risk stratification to select patients who would benefit from adjunctive angiography. Clinical variables associated with the presence of underlying culprit CAD in OHCA survivors include: diabetes mellitus, a history of pre-existing CAD, and ST segment shift (ST elevation or depression) on the post-ROSC ECG. Post arrest troponin elevation has limited sensitivity and sensitivity for predicting culprit CAD post OHCA. Predicting an Acute Coronary Lesion in OHCA Survivors
Slide 32-

We suggest that the clinical likelihood of an acute ischemic etiology from an acute coronary lesion be used to guide the use of timing of angiography in this population (Strong Recommendation, Low Quality Evidence) Recommendation
Slide 33-

Observational studies have demonstrated that the concomitant use of TTM with PPCI for STEMI is technically feasible and not associated with a significant delay to reperfusion, nor with worsened neurological outcomes related to antiplatelet and antithrombotic-mediated intracranial bleeding. Non-RCTs have reported improved survival and neurologic outcomes when PPCI is performed concurrently with TTM amongst post-arrest patients. Combined TTM and Coronary Angiography in OHCA Survivors
Slide 34-

We suggest that TTM be initiated along with angiography in comatose patients if both are required concurrently. (Conditional Recommendation, Low Quality Evidence) Recommendation
Slide 35-

TTM initiation should be considered as soon as clinically feasible in all post-arrest patients who require revascularization. The use of TTM should never delay the process of revascularization. Individual care providers should choose a system and algorithm that would be best suited to their institutional needs when initiating concomitant angiography and TTM for post-arrest patients. Practical Tips:
Slide 36-

Critical Care Management
Slide 37-

Body temperature measurement Sedation and analgesia Neuromuscular blocking agents Oxygenation targets Ventilation targets Serum lactate measurement Mean arterial pressure goals CVP monitoring Optimal hemoglobin targets Prophylactic anti-arrhythmic therapy 3. Critical care management
Slide 38-

Recommendation: Continuous temperature monitoring from arrival to the end of the re-warming phase No preference for monitoring location Conditional Recommendation, Very Low Quality Evidence Values and preferences: Core body temperature probes suggested PAC, nasopharyngeal, esophageal, rectal, or bladder probes 3.2 Body temperature
Slide 39-

Recommendation: Patients managed with TTM should receive analgesics and sedation Titrate according to a validated sedation scoring tool Goal is to optimize patient comfort, reduce anxiety, and reduce duration of mechanical ventilation Conditional Recommendation, Very Low Quality Evidence Values and Preferences: Paucity of data for use of specific medications 3.3 Sedation and analgesia
Slide 40-

Recommendation: Stepwise approach to reduce shivering with TTM Skin counter-warming, acetaminophen, IV magnesium. Attempt use of opioids, propofol or dexmedetomidine before NMBA Conditional Recommendation, Very Low Quality Evidence Values and Preferences: Avoidance of potential risks of using NMBA Use may be necessary in some cases. 3.4 Neuromuscular blocking agents
Slide 41-

Recommendation: PaO2 between 60-200 mmHg in OHCA patients with known or suspected abnormal cerebral function. Hypoxia (PaO2 <60 mmHg) and hyperoxia (PaO2 ≥200 mmHg) should both be avoided. Conditional Recommendation, Low Quality of Evidence Values and Preferences: Recommendations derived from many types of studies. Based on many clinical situations, hyperoxia and hypoxia appear to be harmful and should be avoided. 3.5 Oxygenation targets
Slide 42-

Recommendation: In patients undergoing mechanical ventilation after OHCA who have known or suspected abnormal cerebral function, ventilation should be adjusted to target normocapnia (PaCO2 35-45 mmHg) Conditional Recommendation, Low Quality Evidence Values and Preferences: This recommendation is based upon the known adverse outcomes associated with ventilator-associated hypocapnia. While we recognize that the association of mild hypercapnia with clinical outcomes is not as clear, we still believed it is reasonable to aim for normocapnia as a preferred ventilation target. 3.6 Ventilation targets
Slide 43-

Recommendation: Serial serum lactate levels be followed in the post-OHCA period for at least 24-hours Conditional Recommendation, Low Quality Evidence Practical Tip: Although observational data has linked initially elevated lactate levels and decreased lactate clearance with poor outcomes, it remains unclear whether specific therapy targeted towards decreasing serum lactate levels improves OHCA patient outcomes. Failure to achieve lactate clearance targets should prompt a careful reassessment to identify and treat states of ongoing shock. Following serum lactate levels every 4 to 6 hours may help identify patients with ongoing shock that needs to be addressed. 3.7 Serum lactate measurement
Slide 44-

Recommendations: MAP target of at least 65 mmHg be maintained in OHCA patients, using intravenous fluids, vasopressors and/or inotropes as necessary. Conditional Recommendation, Low Quality Evidence 3.8 Mean arterial pressure
Slide 45-

Recommendation: All hemodynamically unstable OHCA patients have CVP monitoring No specific minimum value recommendation, to help guide management efforts. Conditional Recommendation, Very Low Quality of Evidence Practical Tip: A CVP range of 8-12 mmHg is the most commonly cited target in the ICU literature. The optimal CVP goal remains unclear for OHCA patients. CVP hemodynamic trends are likely of greater clinical importance than a single absolute value, and optimal CVP values for individual patients may differ based on concomitant and/or complicating clinical considerations. 3.9 Central venous pressure
Slide 46-

Recommendation: Transfusion of red blood cells for a hemoglobin ≤80mg/dL in patients following OHCA Conditional Recommendation, Very Low Quality Evidence Values and Preferences: This recommendation recognizes the inability to assess active cardiac symptoms in patients undergoing TTM and the high prevalence of CAD and ACS associated with OHCA in whom a hemoglobin concentration ≥80mg/dL is recommended. Practical Tip: Transfusion at a higher hemoglobin concentration may be considered if there is evidence of ongoing inadequate oxygen delivery after cardiac output has been optimized. 3.10 Hemoglobin
Slide 47-

Recommendation: Reasonable to initiate prophylactic antiarrhythmic medications early in the hospital course in patients with recurrent episodes of VF/VT, non-sustained episodes of VT, or a high burden of ventricular ectopy. Conditional Recommendation, Very Low Quality Evidence Values and Preferences: Importance to reduce recurrent hemodynamically compromising arrhythmias 3.11 Prophylactic antiarrhythmic drugs

Conclusions
Slide 60-

Overall Perspective Application of an cardiac arrest care bundle, focusing on 4 key topics, be utilized for the care of the post-arrest patient 1. Target Temperature Management (TTM) Strongly recommend the use of TTM as opposed to no TTM in the post-arrest population with an initial shockable rhythm Select a specific target temperature between 33ºC to 36ºC, inclusively, and maintain for at least 24 hours
Slide 61-

Overall Perspective 2. Coronary angiography and revascularization Emphasize the role of reperfusion therapy in cardiac arrest patients with STEMI Importance of coordinating TTM with coronary angiography We provide recommendations on the use of diagnostic angiography when the post-ROSC ECG is not diagnostic for STEMI
Slide 62-

Overall Perspective 3. Critical care management We provide recommendations regarding optimizing important hemodynamic, ventilatory, and biochemical parameters in the cardiac arrest population 4. Regionalization of post-arrest care We made strong recommendations to develop and implement best care practices and pathways and ensure timely access to appropriate specialized care
