Background: Epinephrine remains a staple in cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OHCA).  However, the optimal dose, timing, and route of administration are still unknown.  Standard dosing of epinephrine is 1mg every 3 to 5 minutes via the intravenous (IV) or intraosseous (IO) route. IO lines are quicker to establish and have a higher first-attempt success rate compared to IV access. Rapid placement and ease of use minimizes delays for critical patients requiring quick access. The literature, although methodologically limited, is mixed about the use of IV vs IO access for epinephrine in OHCA.

A 57-year-old man is watching his son’s baseball game when he suddenly collapses. Witnesses did not appreciate a pulse, so they started CPR. Unfortunately, an AED was not available. EMS was called and when they arrived within minutes the patient was found to be in vfib arrest and was defibrillated. When the patient arrived to the hospital, he was in PEA arrest. Ultrasound of the patient’s heart showed some coordinated cardiac activity. ACLS doesn’t really tell us how to proceed with cardiac activity but not enough to generate a pulse on the monitor.

Take Home Points 
  • No palpable pulse does not equal no perfusion. We aren't great at feeling pulses
  • Patients with moderate to severe signs and symptoms of lithium toxicity should be considered for hemodialysis
  • Always consider serious causes of back pain before simply treating with analgesics
  • Consider trauma as well as other toxic exposures (I.e. CO and CN) in patients with major burns

Background Information: Therapeutic hypothermia is the use of targeted temperature management to reduce neurologic sequelae resulting from the severe ischemia-reperfusion injury that occurs during cardiac arrest primarily from shockable rhythms.1 Although a mainstay treatment in the Advanced Cardiac Life Support (ACLS) guidelines, its use has been widely debated as beneficial in improving neurologic outcomes in post-cardiac arrest patients with non-shockable rhythms.2-7 Recent studies have also questioned the exact temperature at which patients should be cooled.8 The authors of this study sought to assess whether moderate therapeutic hypothermia, compared with targeted normothermia would improve neurologic outcomes in post-cardiac arrest patients who had a non-shockable rhythm.

Background: Epinephrine (adrenaline) remains a central part of management of OHCA in ACLS guidelines. Recent studies (i.e. PARAMEDIC-2) have raised concerns about the efficacy and possible deleterious effects of epinephrine on both overall survival and long-term neurological outcomes. Other observational trials have suggested that there may be a time dependent effect of epinephrine on survival, with earlier timing of epinephrine improving outcomes, and later timing of epinephrine causing deleterious effects[2]. This trial attempts to analyze the association between timing and dose of epinephrine given on survival and neurologic outcomes of patients with OHCA.
