About this study

Official title: Therapeutic Hypothermia After Pediatric Cardiac Arrest (Out of Hospital)

Cardiac arrest is a sudden, unexpected loss of heart function. Therapeutic hypothermia, in which the body's temperature is lowered and maintained several degrees below normal for a period of time, has been used to successfully treat adults who have experienced cardiac arrest. This study will evaluate the efficacy of therapeutic hypothermia at increasing survival rates and reducing the risk of brain injury in infants and children who experience a cardiac arrest while out of the hospital.

Read the detailed description

Cardiac arrest occurs when the heart suddenly stops beating and blood flow to the body is halted. It can occur while people are in the hospital because of a medical condition, or while people are out of the hospital as a result of an accident or other causes. Cardiac arrest is a serious event that is associated with high rates of death and long-term disability. When a person experiences cardiac arrest, insufficient amount of blood flow and oxygen can result in brain injury.

Therapeutic hypothermia is a therapy that involves a controlled lowering of the body temperature and then maintenance of this lower temperature for a period of time. The treatment may result in reduced brain injury. Therapeutic hypothermia has been successfully used in adults who experience cardiac arrest to improve survival rates and health outcomes, and it has also been studied in newborn infants who have suffered from perinatal asphyxia. The purpose of this study is to evaluate the efficacy of therapeutic hypothermia at improving survival rates and reducing brain injury in infants and children who experience cardiac arrest while out of the hospital.

Study researchers will conduct this study in collaboration with the following two pediatric clinical research networks: the Pediatric Emergency Care Applied Research Network (PECARN), funded by the Emergency Medical Services for Children (EMSC) program, and the National Institute of Child Health and Human Development (NICHD) Collaborative Pediatric Critical Care Research Network (CPCCRN).

The study will enroll infants and children who have suffered a cardiac arrest while out of the hospital. Randomization must occur within 6 hours of return of spontaneous circulation. Participants will be randomly assigned to receive either therapeutic hypothermia or therapeutic normothermia. Participants receiving therapeutic hypothermia will have their body temperature reduced to between 32 to 34° Celsius (C) and will remain at this temperature for 2 days. Their body temperature will then be slowly increased to the normal temperature of 36 to 37.5° C, which will be maintained until 5 days after the cardiac arrest. Participants receiving therapeutic normothermia will have their normal temperature maintained between 36 to 37.5° C for 5 days after the cardiac arrest. Special temperature control blankets will be placed to maintain body temperature in the assigned range. After 5 days, each participant's temperature will be managed by their medical care team.

While participants are in the hospital, they will undergo frequent blood and urine collections, chest x-rays, and temperature measurements; parents of participants will complete questionnaires. When participants are ready to leave the hospital, study researchers will perform a physical and functional assessment. Twenty-eight days after the cardiac arrest, researchers will contact parents of participants to gather information on the participants' health and medical condition. At Months 3 and 12, a child development expert will contact parents to gather medical information. At Month 12, participants will attend a study visit for a neurologic examination and testing with a psychologist trained in rehabilitation.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Therapeutic HypothermiaProcedure or surgery

    Participants who are assigned to receive hypothermia will be cooled to a target temperature of 33º C plus or minus 1º C (32 to 34º C). This temperature will be maintained for 48 hours (2 days) and then participants will be warmed to a target temperature of 36.75º C plus or minus 0.75º C (36 to 37.5º C). This temperature will be maintained until 120 hours (5 days) after the cardiac arrest.

  • Therapeutic NormothermiaOther

    Participants who are assigned to receive therapeutic normothermia will have their temperature maintained at 36.75º C plus or minus 0.75º C (36° to 37.5º C) for 120 hours (5 days) after the cardiac arrest.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Survival With Good Neurobehavioral Outcome

    Survival at one-year anniversary of cardiac arrest, with a standardized VABS-II score of 70 or greater per evaluation performed at any time from 30 days prior to until 183 days after the one-year anniversary of cardiac arrest.

    Measured: Survival was assessed at one-year anniversary of cardiac arrest; among survivors at this one-year anniversary, the VABS-II valid assessment window ranged from 30 days prior to until 183 days after the one-year anniversary date.

Secondary outcomes (3)
  1. Survival

    Survival at one year after cardiac arrest

    Measured: Measured at one-year anniversary of cardiac arrest.

  2. Change in Neurobehavioral Function From Pre-cardiac Arrest to 12 Months Post-cardiac Arrest

    Change in VABS-II score from baseline to one year, with death at 1 year treated as worst possible outcome, and lowest possible VABS-II score at one year (regardless of baseline VABS-II score) treated as the second worst possible outcome.

    Measured: Survival was assessed at one-year anniversary of cardiac arrest; among survivors at this one-year anniversary, the VABS-II valid assessment window ranged from 30 days prior to until 183 days after the one-year anniversary date.

  3. Neuropsychological Scores (for Participants That Survive)

    Functioning, as assessed by the Mullen Early Learning Composite (for children age < 5 years 9 months) or by the 2-subset version of the Wechsler Abbreviated Scale of Intelligence (WASI). As these two function measures are scaled in the same fashion, the two age groups are combined.

    Measured: Measured at Month 12
