Patterns of multiorgan dysfunction after pediatric drowning

Area of Science:

• Pediatric critical care medicine
• Drowning research
• Neurology

Background:

• Drowning is a leading cause of pediatric injury death.
• Multiorgan dysfunction and neurologic outcomes are critical in pediatric drowning survivors.
• Understanding differences between respiratory and cardiac arrest in drowning is essential for targeted interventions.

Purpose of the Study:

• To evaluate multiorgan dysfunction patterns in pediatric drowning patients.
• To assess neurologic outcomes in children experiencing respiratory versus cardiac arrest post-drowning.
• To identify differences in organ failure between respiratory arrest and cardiorespiratory arrest in pediatric drowning.

Main Methods:

• Retrospective chart review of pediatric patients (0-21 years) with drowning.
• Analysis of organ dysfunction using Pediatric Logistic Organ Dysfunction Score-1 (PELOD-1) and Pediatric Multiple Organ Dysfunction Score (P-MODS) within 24 hours.
• Neurologic outcome assessment using Pediatric Cerebral and Overall Performance Category Scale at discharge.

Main Results:

• Children with cardiorespiratory arrest (CA) had higher rates of multiorgan failure and poor neurologic outcomes (81%) compared to those with respiratory arrest (RA) (49%).
• Respiratory arrest patients had significantly better neurologic outcomes (p<0.001).
• Common organ failures included respiratory, neurologic, and cardiovascular in both groups, with variations in frequency.

Conclusions:

• Organ failure patterns significantly differ between cardiorespiratory arrest and respiratory arrest in pediatric drowning.
• Multiorgan failure is a key contributor to poor outcomes in pediatric drowning.
• Further research into MOF-targeting therapies to augment cerebral resuscitation in drowning is warranted.
