  Purpose

Cardiac arrest has a very poor prognosis, especially with prolonged efforts at resuscitation, and unfortunately, survivors are often severely neurologically impaired. CPA in children is often the result of a prolonged illness rather than a sudden, primary cardiac event as is frequent in adults. This necessitates that resuscitation research must be conducted separately for pediatric and adult patients. Authorities currently endorse the use of epinephrine for restoring spontaneous circulation based on its ability to maintain diastolic blood pressure and subsequent blood flow to the heart during resuscitation. However, human studies have shown no clear survival benefit of epinephrine and have elucidated concerning adverse effects. Recently, both the European Resuscitation Council and the American Heart Association have recognized the use of vasopressin as a promising vasoconstrictor and an alternative or adjunct to epinephrine in the resuscitation of adults. Vasopressin causes profound vasoconstriction without the adverse effects of epinephrine and is associated with improved blood flow to the heart and brain. This increased cerebral blood flow has been associated with better neurologic outcome in animal studies. In light of compelling animal and human studies of combined vasopressin and epinephrine, pediatric trials are indicated for vasopressin usage in pediatric CPR. This study will evaluate the addition of the administration of vasopressin to standard advanced CPR therapy (epinephrine alone) for pediatric patients that experience in-intensive care unit CPA to assess for improved time to return of spontaneous circulation (ROSC), survival to 24 hours, survival to hospital discharge, and neurologic outcome. When a patient experiences a CPA, standard Pediatric Advanced Life Saving (PALS) protocols as endorsed by the American Heart Association will be initiated. This will include receiving epinephrine as the first vasopressor medication. Patients will then be randomized to receive vasopressin (treatment group) or epinephrine (control group) as the second vasopressor medication, if needed. If more then two doses of vasopressor medication is required in either group, epinephrine will be administered according to the PALS algorithm until the end of the event. All CPA events meeting inclusion criteria will be entered into the National Registry of Cardiopulmonary Resuscitation (NRCPR) Database, which tracts all CPA events at Children's Medical Center Dallas. Prior to commencement of the RCT, a pilot trial of 10 patients will be completed to assess preliminary safety, feasibility, and effectiveness of combination epinephrine-vasopressin for pediatric in-intensive care unit CPA refractory to initial epinephrine dosing. All pilot patients will receive vasopressin as the second vasopressor medication.

Primary Outcome Measures:
  • Combination vasopressin and epinephrine (CPA refractory to cardiopulmonary resuscitation and initial epinephrine dosing) will increase the proportion of patients surviving to hospital discharge by 25% compared to epinephrine alone. [ Time Frame: Immediate ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Combination vasopressin and epinephrine will decrease the time to ROSC [ Time Frame: Immediate ] [ Designated as safety issue: No ]
  • Vasopressin and epinephrine will improve the proportion of CPA survivors with favorable neurologic outcome (short-term Pediatric Overall Performance Category) [POPC] score discharge of 1-3 or unchanged from hospital admission at the time of hospital . [ Time Frame: Period of hospitalization ] [ Designated as safety issue: No ]
  • Vasopressin and epinephrine will improve the proportion of CPA survivors with favorable neurologic outcome (short-term Pediatric Cerebral Performance Category) [PCPC] score of 1-3 or unchanged from hospital admission at time of hospital discharge. [ Time Frame: Period of Hospitalization ] [ Designated as safety issue: No ]
  • Combination vasopressin and epinephrine will improve 24 hour survival. [ Time Frame: 24 hrs ] [ Designated as safety issue: No ]
  • Combination vasopressin and epinephrine will decrease the proportion of patients who require prolonged CPR (CPR > 20minutes) to achieve sustained ROSC. [ Time Frame: Immediate ] [ Designated as safety issue: No ]
  • Combination vasopressin and epinephrine will increase organ recovery in those patients who meet brain death criteria following the CPA event. [ Time Frame: Period of hospitalization ] [ Designated as safety issue: No ]
  • Combination epinephrine and vasopressin will improve rates of return of spontaneous circulation (ROSC) [ Time Frame: Immediate ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

  • All children, ages 0 to 18 years, admitted to the PICU who experience CPA requiring either chest compressions and/or defibrillation. This will include males, females and Spanish speaking individuals.
  • Patients must require at least 2 doses of vasopressor medication during the CPA event (all patients would receive epinephrine as first dose, followed by either epinephrine or vasopressin as second dose depending on randomization, all subsequent doses required would be epinephrine) given via any route (intravenous, intraosseous, or endotracheal).

Exclusion Criteria:

  • Do Not Attempt Resuscitate (DNAR) patients
  • Chemical code only (i.e., no CPR/defibrillation)
  • Events not requiring chest compressions and/or defibrillation
  • Events with a pulse requiring synchronized or unsynchronized cardioversion
  • Successful internal cardiac device defibrillation of Vfib/pVT that initiates the resuscitation event
  • Defibrillation for Vfib/pVT without administration of a vasopressor
  • All patients in the custody of the State of Texas
  • Any patient whose parent or guardian "opts out" of the study
  • Any patient who is pregnant
  • Any patient whose attending physician "opts out" of the study
  • Any patient who does not consent to follow up data collection
