Insights
Cardiopulmonary resuscitation (CPR) in a pediatric intensive care unit (PICU) showed a 32.3% survival to discharge rate. Shorter CPR duration and younger age were linked to better outcomes, highlighting duration as a key factor.
Area of Science:
- Pediatric Critical Care Medicine
- Cardiopulmonary Resuscitation (CPR)
- Clinical Outcomes Research
Background:
- Optimizing patient outcomes after cardiopulmonary resuscitation (CPR) requires understanding survival factors and addressing preventable causes.
- Cardiac arrest and CPR events are critical in pediatric intensive care units (PICUs), necessitating detailed outcome analysis.
Purpose of the Study:
- To determine the prevalence and outcomes of cardiac arrest and CPR in a tertiary pediatric intensive care unit (PICU).
- To identify factors associated with return of spontaneous circulation (ROSC), 24-hour survival, and hospital discharge survival post-CPR.
Main Methods:
- Retrospective analysis of the PICU CPR registry from January 1, 2011, to January 1, 2018.
- Inclusion criteria: Patients undergoing at least 2 minutes of CPR.
- Outcomes assessed: ROSC > 20 minutes, 24-hour survival, and survival to hospital discharge.
Main Results:
- CPR occurred in 65 instances (1.85% prevalence) among pediatric patients (mean age 32.7 months).
- Return of spontaneous circulation (ROSC) was achieved in 58.5%, 24-hour survival in 46.2%, and hospital discharge survival in 32.3%.
- Factors associated with better outcomes included younger age, respiratory cause, bradycardia, and shorter CPR duration. Certain medications (sodium bicarbonate, norepinephrine, vasopressin) were linked to worse outcomes. CPR duration negatively impacted survival by 8.7% per minute.
Conclusions:
- CPR duration is a critical determinant of patient outcomes, emphasizing its importance alongside CPR quality guidelines.
- The survival rate post-ROSC warrants careful consideration for parental counseling.
- Preventing CPR events remains a significant ongoing challenge in pediatric intensive care.
Abstract:
Understanding the factors affecting survival and modifying the preventable factors may improve patient outcomes following cardiopulmonary resuscitation (CPR). The aim of this study was to assess the prevalence and outcomes of cardiac arrest and CPR events in a tertiary pediatric intensive care unit (PICU). Outcomes of interest were the return of spontaneous circulation (ROSC) lasting more than 20 minutes, survival for 24 hours post-CPR, and survival to hospital discharge. We analyzed data from the PICU CPR registry from January 1, 2011 to January 1, 2018. All patients who underwent at least 2 minutes of CPR in the PICU were included. CPR was administered in 65 PICU instances, with a prevalence of 1.85%. The mean patient age was 32.7 months. ROSC occurred in 38 (58.5%) patients, 30 (46.2%) achieved 24-hour survival, and 21 (32.3%) survived to hospital discharge. Younger age ( p < 0.018), respiratory cause ( p < 0.001), bradycardia ( p < 0.018), and short duration of CPR ( p < 0.001) were associated with better outcomes, while sodium bicarbonate, norepinephrine, and vasopressin were associated with worse outcome ( p < 0.009). The off-hour CPR had no impact on the outcome. The patients' cumulative predicted survival declined by an average of 8.7% for an additional 1 minute duration of CPR ( p = 0.001). The study concludes that the duration of CPR, therefore, remains one of the crucial factors determining CPR outcomes and needs to be considered in parallel with the guideline emphasis on CPR quality. The lower survival rate post-ROSC needs careful consideration during parental counseling. Better anticipation and prevention of CPR remain ongoing challenges.
