Insights
High-dose epinephrine did not improve survival rates in pediatric cardiorespiratory arrest. This study found no significant differences in survival outcomes between standard and high-dose epinephrine administration in children.
Area of Science:
- Pediatric Emergency Medicine
- Cardiology
- Critical Care
Background:
- Cardiorespiratory arrest (CRA) in children is a critical event requiring immediate intervention.
- Epinephrine is a first-line medication used in pediatric resuscitation.
- Optimal dosing strategies for epinephrine in pediatric CRA remain under investigation.
Purpose of the Study:
- To compare the survival impact of high-dose versus standard-dose epinephrine in pediatric cardiorespiratory arrest.
- To evaluate the efficacy of intravenous or intraosseous high-dose epinephrine administration.
Main Methods:
- A multicenter, prospective study collected cardiopulmonary resuscitation data from 283 children over 18 months.
- A secondary analysis focused on 92 children treated with intravenous or intraosseous epinephrine.
- Children were categorized into conventional-dose and high-dose epinephrine groups.
Main Results:
- The high-dose epinephrine group received more doses on average compared to the conventional-dose group.
- Children in the conventional-dose group were older and heavier than those in the high-dose group.
- No significant differences were found in survival to hospital discharge or 1-year follow-up between the groups.
Conclusions:
- High doses of epinephrine (0.1 mg/kg) do not appear to improve survival in pediatric cardiorespiratory arrest.
- Further research is needed to confirm these findings due to study limitations.
- Current evidence suggests standard dosing may be sufficient for pediatric CRA resuscitation.
Objective:
To evaluate the impact on survival of intravenous or intraosseous high-dose epinephrine compared with standard doses in children with cardiorespiratory arrest.
Material And Methods:
We performed a multicenter, prospective study. Cardiopulmonary resuscitation data from 283 children was collected following international guidelines (Utstein style) over 18 months. In a secondary analysis we studied survival in 92 children who were treated with intravenous or intraosseous epinephrine.
Results:
One or more conventional doses of epinephrine (0.01 mg/kg) were administered in 12 patients and a first conventional dose followed by one or more high doses (0.1 mg/kg) were administered in 80 patients. The age and weight of children in the conventional-dose group were higher than those in the high-dose group (97.1 +/- 70.5 months vs 29.9 +/- 36.9 months, p = 0.03 and 24.7 +/- 20.8 kg vs 11.9 +/- 8.9 kg, p = 0.037, respectively). The number of doses administered in the conventional-dose group was lower than that in the high-dose group (4 +/- 4 vs 5.4 +/- 3.4, p = 0.01). No significant differences were observed between the two groups in type of arrest, site of arrest, initial electrocardiographic rhythm, response to resuscitation attempts with return of spontaneous circulation, total resuscitation time, neurological status at the end of the episode and survival to hospital discharge and at 1-year of follow-up.
Conclusion:
Although the present study has considerable limitations, the results suggest that high doses of epinephrine do not improve survival in cardiorespiratory arrest in children.

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
