Cardiopulmonary resuscitation in a pediatric ICU
Insights
Pediatric cardiac arrest (CPR) in the ICU is often anticipated and non-respiratory. Central nervous system status significantly impacts survival outcomes following resuscitation efforts.
Area of Science:
- Pediatric Critical Care Medicine
- Cardiopulmonary Resuscitation
- Pediatric Intensive Care Unit (PICU) Outcomes
Background:
- Cardiopulmonary resuscitation (CPR) is a critical intervention in pediatric intensive care units (PICUs).
- Understanding the specific characteristics and outcomes of CPR in the PICU setting is essential for improving patient care.
- Previous studies have focused on out-of-hospital or general ward arrests, necessitating a focused analysis of PICU arrests.
Purpose of the Study:
- To retrospectively analyze the incidence, characteristics, and outcomes of CPR in a medical/surgical pediatric intensive care unit.
- To identify factors influencing survival and discharge following CPR in critically ill children.
- To compare PICU arrests with those occurring in other settings.
Main Methods:
- Retrospective study of 121 CPR episodes over 30 months in a 10-bed pediatric ICU.
- Data collected included patient admissions, cumulative PICU days, CPR success rates, and survival durations.
- Analysis of factors associated with CPR outcomes, including pre-arrest central nervous system (CNS) status.
Main Results:
- 64% of CPR attempts were initially successful, with 48% achieving at least 24-hour survival and 31% resulting in PICU discharge.
- PICU arrests were typically anticipated, non-respiratory in origin, and occurred despite aggressive medical support.
- Pre-arrest CNS status was the most significant predictor of outcome; 29% of patients with prolonged resuscitation survived without coma.
Conclusions:
- CPR in the PICU has distinct characteristics compared to other settings, often occurring in critically ill patients with complex underlying conditions.
- While initial success rates are moderate, long-term survival and discharge are less common, highlighting the severity of illness.
- Central nervous system status is a crucial determinant of survival, emphasizing the importance of neurological assessment in predicting CPR outcomes.
Abstract:
A 30-month, retrospective study of CPR was undertaken in a 10-bed, medical/surgical pediatric ICU (PICU). The 121 episodes of CPR reviewed represented 81 of 1357 admissions and 7537 cumulative days of PICU care. Of the 121 CPR attempts, 64% were initially successful, 48% were associated with at least 24-h survival, and 31% were followed by discharge from PICU. Unlike pediatric arrests outside the hospital or on general pediatric wards, PICU arrests were seldom unanticipated, were commonly nonrespiratory in origin, and generally occurred in spite of aggressive support. Of 118 PICU deaths during the study period, 45 (38%) were associated with CPR. In the 73 remaining PICU deaths, CPR had been withheld because of an order not to resuscitate. CNS status before arrest was the most important factor influencing outcome. In this pediatric population, 29% were noncomatose survivors 24 h after more than 30 min of resuscitation.
