The Pediatric Submersion Score Predicts Children at Low Risk for Injury Following Submersions

Drowning

Drowning is responsible for considerable morbidity and mortality worldwide, and it is estimated that 90% of drownings are preventable. Drowning is defined as "the process of experiencing respiratory impairment from submersion/immersion in liquid." Emergency providers should focus on airway management and rapid delivery of oxygen to interrupt the drowning process and improve patient outcomes. Patients with minimal or no symptoms do not require any specific diagnostic workup, aside from physical examination and 4 to 6 hours of observation prior to discharge. Patients with more severe symptoms may present with rales and foamy secretions, and should be managed with high-concentration oxygen and positive airway pressure.

Wilderness Medical Society Clinical Practice Guidelines for the Treatment and Prevention of Drowning: 2024 Update

The Wilderness Medical Society convened a panel to review available evidence supporting practices for acute management of drowning in out-of-hospital and emergency care settings. Literature about definitions and terminology, epidemiology, rescue, resuscitation, acute clinical management, disposition, and drowning prevention was reviewed. The panel graded available evidence supporting practices according to the American College of Chest Physicians criteria and then made recommendations based on that evidence. Recommendations were based on the panel's collective clinical experience and judgment when published evidence was lacking. This is the second update to the original practice guidelines published in 2016 and updated in 2019.

Epidemiology, clinical aspects, and management of pediatric drowning

Drowning is the third leading cause of injury death in the pediatric population worldwide, with incidence peaking among those aged 1-4 years and again in adolescence.The purpose of this commentary is to review the basic pathophysiology of drowninginjury and factors that affect the outcome, such as submersion and hypothermia. We also discuss principles of prehospital and in-hospital management, comprising resuscitation and stabilization, administration of oxygen and intravenous liquids, and central reheating.Even though the mortality rate has decreased in recent years, further investments and safety measures are needed to prevent child drowning deaths.

Addressing gaps in our understanding of the drowning patient: a protocol for the retrospective development of an Utstein style database and multicentre collaboration

INTRODUCTION

This retrospective observational study aims to create a comprehensive database of the circumstances of drowning (including care provided and outcomes of care) to report against the Utstein style for drowning (USFD) for patients presenting to the emergency department (ED). Four areas will be examined: a feasibility study of the USFD; a comparison of classification and prognostication systems; examination of indications and efficacy of different ventilation strategies; and differences in the circumstances, severity, treatment and outcomes of drowning by sex and gender.

METHODS AND ANALYSIS

This protocol outlines retrospective data collection for all patients presenting to EDs of the Sunshine Coast Hospital and Health Service in Queensland, Australia with the presenting problem or discharge diagnosis of drowning or immersion between 2015 and 2022. Patients computerised health records (emergency medical service record, pathology, radiology results, medical and nursing notes for ED, inpatient units and intensive care units) will be used to extract data for entry into an USFD database. Descriptive (eg, median, IQR) and inferential statistical analyses (eg, analysis of variance) will be used to answer the separate research questions. Development of an International Drowning Registry using the USFD dataset and the Research Electronic Data Capture (REDCap) web application is discussed.

ETHICS AND DISSEMINATION

This study has been approved by Metro North Human Research and Ethics Committee (Project No: 49754) and James Cook University Human Research Ethics Committee (H8014). It has been endorsed by national drowning prevention organisations Royal Life Saving Society Australia (RLSSA) and Surf Life Saving Australia (SLSA). Study findings will provide data to better inform clinical management of drowning patients and provide an evidence base on sex and gender differences in drowning. Results will be disseminated through peer review publications, conference presentations and media releases. Results will also be disseminated through RLSSA and SLSA membership of the Australian and New Zealand Resuscitation Council and the Australian Water Safety Council.

Epidemiology of paediatric drowning hospitalisations in the USA: a population-based study

BACKGROUND

Drowning is a leading cause of death in children ≤5 years old. Detailed data on the epidemiology of drowning in this high-risk population can inform preventative efforts. We aimed to study trends in incidence and case fatality rates (CFR) in the USA among young children hospitalised after drowning.

METHODS

Children ≤5 years old hospitalised in the USA after drowning were identified from the Kids Inpatient Database 2000-2016. Incidence and CFRs by calendar year, age, sex, race/ethnicity and hospital region were calculated. Trends over time were evaluated. Factors associated with fatal drowning were assessed.

RESULTS

Among 30 560 804 hospitalised children ≤5 years old, 9261 drowning cases were included. Patients were more commonly male (62.3%) and white (47.4%). Two years old had the highest incidence of hospitalisation after drowning, regardless of race/ethnicity, sex and region. Overall drowning hospitalisations decreased by 49% from 2000 to 2016 (8.38-4.25 cases per 100 000 children). The mortality rate was 11.4% (n=1060), and most occurred in children ≤3 years old (83.0%). Overall case fatality decreased between 2000 and 2016 (risk ratio (RR) 0.44, 95% CI 0.25 to 0.56). The lowest reduction in incidence and case fatality was observed among Black children (Incidence RR 0.92, 95% CI 0.75 to 1.13; case fatality RR 0.80, 95% CI 0.41 to 1.58).

CONCLUSIONS

Hospitalisations and CFRs for drowning among children ≤5 years old have decreased from 2000 to 2016. Two years old are at the highest risk of both fatal and non-fatal drowning. Disparities exist for Black children in both the relative reduction in drowning hospitalisation incidence and case fatality. Interventions should focus on providing equitable preventative care measures to this population.

Prevention of Drowning

Drowning is a leading cause of injury-related death in children. In 2018, almost 900 US children younger than 20 years died of drowning. A number of strategies are available to prevent these tragedies. As educators and advocates, pediatricians can play an important role in prevention of drowning.

Resuscitation and emergency care in drowning: A scoping review

BACKGROUND

The ILCOR Basic Life Support Task Force and the international drowning research community considered it timely to undertake a scoping review of the literature to identify evidence relating to the initial resuscitation, hospital-based interventions and criteria for safe discharge related to drowning.

METHODS

Medline, PreMedline, Embase, Cochrane Reviews and Cochrane CENTRAL were searched from 2000 to June 2020 to identify relevant literature. Titles and abstracts and if necessary full text were reviewed in duplicate. Studies were eligible for inclusion if they reported on the population (adults and children who are submerged in water), interventions (resuscitation in water/boats, airway management, oxygen administration, AED use, bystander CPR, ventilation strategies, ECMO, protocols for hospital discharge (I), comparator (standard care) and outcomes (O) survival, survival with a favourable neurological outcome, CPR quality, physiological end-points).

RESULTS

The database search yielded 3242 references (Medline 1104, Pre-Medline 202, Embase 1722, Cochrane reviews 12, Cochrane CENTRAL 202). After removal of duplicates 2377 papers were left for screening titles and abstracts. In total 65 unique papers were included. The evidence identified was from predominantly high-income countries and lacked consistency in the populations, interventions and outcomes reported. Clinical studies were exclusively observational in nature.

CONCLUSION

This scoping review found that there is very limited evidence from observational studies to inform evidence based clinical practice guidelines for drowning. The review highlights an urgent need for high quality research in drowning.

Correlation of clinical and chest radiograph findings in pediatric submersion cases

BACKGROUND

Submersion injuries are a leading cause of injury death in children in the United States. The clinical course of a submersion patient varies depending on the presence of anoxic brain injury and acute respiratory failure.

OBJECTIVE

We studied changes in clinical findings and chest radiograph findings and determined the sensitivity/specificity of the presenting chest radiograph in predicting clinical improvement within the first 24 h in pediatric submersion cases.

MATERIALS AND METHODS

We conducted a cross-sectional study of pediatric submersion patients through age 18 years treated at a children's hospital from 2010 to 2013. We reviewed demographics, comorbidities, prehospital/hospital course and chest radiographic findings. Clinical improvement occurred when a child demonstrated normal vital signs and mentation. We compared radiographic findings among children based on clinical improvement up to 24 h post submersion. Using odds ratios, we calculated associations between radiographic findings and clinical improvement. We studied the sensitivity/specificity of the presenting chest radiograph in predicting clinical improvement within 24 h.

RESULTS

One hundred forty-two of 262 (54%) patients had initial chest radiographs; 41% had follow-up radiographs. The odds of an abnormal initial chest radiograph were 4 times higher in children with respiratory distress or abnormal mentation at emergency department (ED) presentation compared to children without these findings (odds ratio [OR]=4.83; 95% confidence interval [CI]=2.1-10.85; P<0.001). Improvement in radiographic findings occurred in 85% of children within 24 h. Children with an abnormal initial chest radiograph were 87% less likely to improve clinically by 24 h (P<0.001). A presenting chest radiograph that was normal or with mild pulmonary edema/atelectasis predicted clinical improvement within 24 h (sensitivity 95%, specificity 57%).

CONCLUSION

Most chest radiographic findings improve in pediatric submersion patients who recover within the first 24 h. An initial chest radiograph that is normal or with mild pulmonary edema/atelectasis satisfactorily predicts clinical improvement by 24 h post submersion.
