Insights
Long-term outcomes for children surviving submersion-related cardiac arrests (CA) show favourable neurological status but significant neuropsychological deficits. Standardized follow-up care is crucial for pediatric drowning survivors.
Area of Science:
- Pediatric critical care medicine
- Neurology
- Public health
Background:
- Submersion-related cardiac arrests (CA) in children present significant challenges for long-term survival and recovery.
- Understanding the long-term neurological and cognitive outcomes is essential for guiding patient care and rehabilitation strategies.
Purpose of the Study:
- To investigate the long-term outcomes, including neurological status and neuropsychological functioning, in children who experienced submersion-related cardiac arrests.
- To identify potential deficits and inform the need for structured follow-up protocols.
Main Methods:
- A cohort of children (1 day–17 years) admitted to a pediatric hospital between 2002 and 2019 following drowning with CA were included.
- Primary outcome was survival with favorable neurological outcome (Pediatric Cerebral Performance Category [PCPC] 1-3). Secondary outcomes included age-appropriate neuropsychological assessments.
- Follow-up duration varied, with a median of 2.3 years for neurological status and 4.0 years for neuropsychological assessments.
Main Results:
- Of 99 children included, 40 died in-hospital and 4 post-discharge. Among survivors (n=52), 47 had favorable neurological outcomes (PCPC 1-3).
- Twenty-six children underwent neuropsychological assessments, revealing significantly lower general and performance intelligence scores, processing speed, and visual motor integration compared to normative data.
- These deficits were statistically significant (p < 0.01) across multiple cognitive domains.
Conclusions:
- While many pediatric drowning survivors achieve favorable neurological status, significant long-term neuropsychological deficits persist.
- This highlights the critical need for standardized, long-term follow-up programs as a standard of care for children following submersion-related cardiac arrests.
- Early identification and intervention for cognitive impairments are vital for optimizing recovery and quality of life in this population.
Aim:
Investigate long-term outcome in paediatric submersion-related cardiac arrests (CA).
Methods:
Children (age one day-17 years) were included if admitted to the Erasmus MC Sophia Children's Hospital, after drowning with CA, between 2002 and 2019. Primary outcome was survival with favourable neurological outcome, defined as a Paediatric Cerebral Performance Category (PCPC) score of 1-3 at longest available follow-up. Secondary outcome were age-appropriate neuropsychological assessments at longest available follow-up.
Results:
Upon hospital admission, 99 children were included (median age at time of CA 3.2 years [IQR 2.0-5.9] and 65% males). Forty children died in-hospital (no return of circulation (45%) or withdrawal of life sustaining therapies (55%)) and 4 children deceased after hospital discharge due to complications following the drowning-incident. Among survivors, with a median follow-up of 2.3 years [IQR 0.2-5.5], 47 children had favourable neurological outcome (i.e. PCPC 1-3) and 8 children unfavourable (unfavourable outcome group total n = 52, i.e. PCPC 4-5 or deceased). Twenty-six (47%) children participated in a neuropsychological assessment (median follow-up 4.0 years [IQR 2.3-8.7]). Compared with normative test data, participants obtained worse general (p = 0.008) and performance (p = 0.003) intelligence scores, processing speed (p = 0.002) and visual motor integration scores (p = 0.0012).
Conclusions:
Although overall outcome in survivors was favourable at longest available follow-up, significant deficits in neuropsychological assessments were found. This study underlines the need for a standardized long term follow-up program as standard of care in paediatric drowning with CA.
