    Summary
    This summary is machine-generated.

    Secondary drowning, a post-immersion respiratory syndrome, affects 5% of near-drowning cases. Prompt recognition and treatment improve outcomes, especially after fresh water immersion.

    Area of Science:

    • Pediatrics
    • Emergency Medicine
    • Pulmonology

    Background:

    • Secondary drowning (and near-drowning) is a post-immersion respiratory syndrome.
    • It involves pulmonary function deterioration due to surfactant loss or inactivation, impairing gas exchange.

    Purpose of the Study:

    • To review the incidence and characteristics of secondary drowning in childhood near-drowning incidents.
    • To analyze the impact of water type (fresh vs. salt) on secondary drowning outcomes.

    Main Methods:

    • Retrospective review of 94 consecutive childhood near-drowning cases.
    • Analysis of syndrome onset, latent period, and patient outcomes based on immersion water type.

    Main Results:

    • Secondary drowning occurred in 5% (5/94) of cases, typically with a rapid onset after a 1-48 hour latent period.

  • Fresh water immersion led to more rapid onset compared to salt water.
  • Children immersed in fresh water recovered completely, while those in salt water died.

    • Conclusions:

    • Secondary drowning prognosis is favorable in fresh water cases with prompt recognition and vigorous treatment.
    • Outcomes are poor following salt water immersion, highlighting the critical role of water type in prognosis.
