Pediatric submersion injuries: emergency care and resuscitation.

Drowning and submersion injuries are highly prevalent, yet preventable, causes of pediatric mortality and morbidity. Prehospital care should focus on restoring normal ventilation and circulation as quickly as possible to limit the extent of hypoxic insult. Diagnostic testing for symptomatic patients may include blood glucose level, arterial blood gas level, complete blood count, electrolyte levels, chest radiography, and cardiorespiratory monitoring with pulse oximetry and a rhythm strip. In this review, passive external, active external, and active internal rewarming techniques for treatment of hypothermic patients are discussed. A systematic approach to treatment and disposition of pediatric drowning victims is provided, and risk factors, caveats in pediatric care, and factors affecting prognosis are also discussed.

A reappraisal of childhood drowning in a pediatric emergency department.

BACKGROUND: In the present study, we aimed to investigate the demographic and clinical features, laboratory and radiologic characteristics, management, and outcomes of pediatric drowning patients in order to identify predictors of hospital admission, and to evaluate the need for respiratory support, and prognosis. METHODS: In this retrospective chart review, children aged 0 to 18 years who presented to the pediatric emergency department due to drowning between July 2009 and September 2019 were included. Demographics, initial vital signs, clinical findings, laboratory and radiologic results, and the need for respiratory support or cardiopulmonary resuscitation in the emergency department were recorded. Subjects were divided into 6 groups using the Szpilman classification system. RESULTS: A total of 89 patients were enrolled. Among the children who were admitted to the hospital, initial Szpilman score, crepitations on lung auscultation, and pathologic chest X-ray (CXR) findings were higher and Glasgow Coma Score and oxygen saturation (SpO 2) levels were lower than those of children who were discharged from the emergency department. A Szpilman score of ≥4, a lactate level of >2 mmol/L, and pathologic CXR findings were identified as predictors of hospital admission. Of the 89 patients, 22 (24.7%) underwent non-invasive ventilation (NIV) treatment and were classified as grade 3 or 4 according to the Szpilman score. Length of stay in the pediatric intensive care unit (PICU) and in the hospital was lower in patients who underwent NIV. As the Szpilman score increased as of grade 3, a positive correlation was observed with lactate levels (p <0.001, r: 0.552) and the total length of stay in the hospital (p: 0.001, r : 0.491), both of which gradually increased. CONCLUSION: The Szpilman score was associated with the duration of hospital stay and the degree of hypoxia, so it could help the physician make rapid decisions on ventilation strategy. Application of NIV in the emergency department shortened the length of stay in the PICU and in the hospital, suggesting that it can be used more often in pediatric emergency settings.

Fifteen-minute consultation: Drowning in children.

Drowning is a significant cause of childhood morbidity and mortality globally. The underlying mechanisms vary with child development and most are modifiable to public health promotion strategies. This article serves to highlight some of the specific considerations for the clinical management of drowning in children, both prehospital and by the in-hospital paediatric resuscitation team. This includes changes to standard advanced paediatric life support in the presence of hypothermia.

Predictors for hospital admission of asymptomatic to moderately symptomatic children after drowning.

Drowning is a leading cause of injury-related death worldwide, but there are limited data on the management and disposition of asymptomatic and mildly symptomatic adults and children following a drowning event. Some authors have recommended admission for all drowning victims due to the possibility of respiratory and clinical deterioration in a seemingly well patient. In order to identify predictors for admission and to establish a unified approach for management, we retrospectively collected all children ≤ 16 years old presented following a drowning event to the pediatric ED over a period of 12 years. The children were divided into two groups, those who were discharged home from the ED and those who were admitted. Seventy-one surviving and non-intubated children were asymptomatic to moderately symptomatic, and they comprised the study group. Crepitations on lung auscultation, oxygen desaturation, and respiratory distress were significantly higher in the admitted group (n = 26) compared with the discharged group (n = 45) (P < 0.05). Respiratory distress and lung crepitations were independent predictors for admission. Eventually, 30% of the hospitalized patients required oxygen therapy, but there were no cases that deteriorated and required invasive ventilation. No readmissions occurred in the group of children who were discharged from the ED.Conclusion: Children who after six hours show no respiratory distress and have normal oxygen saturation and normal auscultation can be safely discharged home. Respiratory distress and lung crepitations should both warrant the physician to consider admission of asymptomatic to moderately symptomatic children following a drowning event. An algorithm to assist patient management is proposed. What is Known: •There are few data in the literature regarding the management and disposition of asymptomatic to moderately symptomatic children after drowning. What is New: •We found that respiratory distress and lung crepitations are independent predictors for admission. An algorithm to assist patient management is proposed.

Unresponsive Wakefulness Syndrome in Children after Near-Drowning: Long-Term Outcome and Impact on the Families.

Among 131 children admitted to our institution for early phase rehabilitation after freshwater near-drowning (ND) between the year 1986 and 2000, 87 were in unresponsive wakefulness syndrome (UWS) for at least 4 weeks after the accidents. An anonymous questionnaire was sent to the families after 0.5 to 15.0 years (median: 4.6) and 48 mothers and 51 fathers of 55 of these 87 children were interviewed after 6.6 to 23.8 years (median: 13.8) of ND. At the time of the interviews, 8/55 children were able to perform daily living activities independently, 36/55 children were not able to do so (many of them suffered from chronic medical conditions like spasticity or disorders of swallowing), and 11/55 children had died. Health-related quality of life (HRQoL) was, however, similar to the normal population for mothers, and even higher for fathers. Furthermore, the ND accident had apparently not lead to a higher rate of separations of parents but had increased their likelihood to have further children. Feelings of guilt were highly prevalent (23/47 mothers, 20/47 fathers), and correlated with lower HRQoL of the respective parent. We found correlations between duty of supervision and feelings of guilt and between outcome and HRQoL for only the fathers. In conclusion, we found that after 4 weeks in UWS, the long-term neurological outcome of pediatric ND victims is often but not always poor. Despite often severe disabilities or death of the child during long-term care, parents surprisingly report little impact on their HRQoL, on the stability of their partnership or on their wish to have further children. Our findings may help parents and physicians to choose the best treatment for a child in UWS due to different etiologies striking the balance between rehabilitation and palliative care.

Pediatric near-drowning events: do they warrant trauma team activation?

BACKGROUND: The purpose of this study was to determine the incidence of traumatic injuries, factors associated with mortality, and need for pediatric trauma surgery involvement for drowning and near-drowning events in children. MATERIALS AND METHODS: An institutional review board-approved, retrospective chart review was performed at three American College of Surgeons-verified Pediatric Trauma Centers (2011-2014). Patients with International Classification of Diseases, Ninth Revision, codes or E-codes for fatal-nonfatal drowning, fall into water, accidental drowning, or submersion were included. Bivariate analysis using chi-square or Fisher exact test for nominal variables and Mann-Whitney U test for continuous variables was performed. RESULTS: A total of 363 patients (median 3.17 y [18 d-17 y]) met the inclusion criteria. Drowning sites included pool (81.5%), bathtub (12.9%), and natural water (5.2%). A witnessed fall or dive was reported in 34.9%, 57.9% did not fall or dive, and 7% had an unwitnessed event. Most patients did not undergo cervical spine (83%) or brain imaging (75.5%). Seven patients (1.92%) had associated soft tissue injuries. Two patients (0.006%) received surgical intervention (bronchoscopy and extracorporeal membrane oxygenation) within 24 h of presentation. Only 2.2% were admitted to the pediatric trauma service. The percentage of patients discharged home from the emergency department was 10.2%. Overall mortality was 12.4%. Factors associated with mortality included transfer from outside hospital (P = 0.016), presence of hypothermia on arrival (P < 0.0001), Glasgow Coma Scale of 3 on arrival (P < 0.0001), drowning in a pool (P = 0.013), or undergoing brain cooling at admission (P = 0.011). CONCLUSIONS: This is the largest reported series of pediatric near-drowning events. Only rarely did patients require immediate surgical attention and the majority were admitted to nonsurgical services. These data suggest that routine pediatric trauma surgery service involvement in patients with near-drowning events may be unnecessary.

[Drowning - An update on prehospital and intrahospital treatment strategies]. / Update Ertrinkungsunfall - Präklinische und klinische Therapiestrategien.

500000 people die from unintentional drowning each year worldwide. Drowning accidents occur to humans of every age, while fatal drowning is the leading cause of death among boys 5 to 14 years of age. In Germany, however, most drowning victims are elderly people. Considering the multitude of accident settings, ranging from bathing accidents in lakes to shipwrecks at sea, professional first responders need to adapt to various scenarios. This article summarizes the pathophysiology of drowning, particular features of prehospital life support and current knowledge on the further therapy of victims of near fatal drowning accidents.

Brain resuscitation in the drowning victim.

Drowning is a leading cause of accidental death. Survivors may sustain severe neurologic morbidity. There is negligible research specific to brain injury in drowning making current clinical management non-specific to this disorder. This review represents an evidence-based consensus effort to provide recommendations for management and investigation of the drowning victim. Epidemiology, brain-oriented prehospital and intensive care, therapeutic hypothermia, neuroimaging/monitoring, biomarkers, and neuroresuscitative pharmacology are addressed. When cardiac arrest is present, chest compressions with rescue breathing are recommended due to the asphyxial insult. In the comatose patient with restoration of spontaneous circulation, hypoxemia and hyperoxemia should be avoided, hyperthermia treated, and induced hypothermia (32-34 °C) considered. Arterial hypotension/hypertension should be recognized and treated. Prevent hypoglycemia and treat hyperglycemia. Treat clinical seizures and consider treating non-convulsive status epilepticus. Serial neurologic examinations should be provided. Brain imaging and serial biomarker measurement may aid prognostication. Continuous electroencephalography and N20 somatosensory evoked potential monitoring may be considered. Serial biomarker measurement (e.g., neuron specific enolase) may aid prognostication. There is insufficient evidence to recommend use of any specific brain-oriented neuroresuscitative pharmacologic therapy other than that required to restore and maintain normal physiology. Following initial stabilization, victims should be transferred to centers with expertise in age-specific post-resuscitation neurocritical care. Care should be documented, reviewed, and quality improvement assessment performed. Preclinical research should focus on models of asphyxial cardiac arrest. Clinical research should focus on improved cardiopulmonary resuscitation, re-oxygenation/reperfusion strategies, therapeutic hypothermia, neuroprotection, neurorehabilitation, and consideration of drowning in advances made in treatment of other central nervous system disorders.

Feasibility of pulse oximetry in the initial prehospital management of victims of drowning: a preliminary study.

AIM: Immediate delivery of oxygen is the most important treatment for victims of drowning at the rescue site. Monitoring oxygen saturation with pulse oximetry is potentially useful, but its use may be limited by poor peripheral perfusion due to hypothermia. This preliminary study explores the feasibility of pulse oximetry in simulated minor drowning scenarios. MATERIALS AND METHODS: Six different pulse oximeters were tested on ten healthy volunteers after brief submersion, after ten minutes of swimming in a swimming pool (warm water, temperature 21°C), and in the sea (cold water, temperature 16°C). A measured oxygen saturation reading ≤ 94% was assumed to be incorrect. RESULTS: There was considerable variability between each pulse oximeter. In warm water, 5.8% of measurements were outside the predicted range (8.3% after submersion, 3.3% after swimming), compared to 34% in cold water (20% after submersion, 48% after swimming). The spurious measurements came from two pulse oximeters in warm water, but from all six in cold water. The best and worst performing pulse oximeters showed 5% and 33% measurements respectively outside the predicted range. CONCLUSION: The performance of pulse oximeters varies considerably in healthy volunteers submersed or immersed in warm or cold water. Further studies are needed to understand these differences.

Rescue a drowning patient by prolonged extracorporeal membrane oxygenation support for 117 days.

Drowning is one of the most common causes of accidental events. Here we report a drowning patient who experienced acute respiratory distress syndrome after hospitalization. Although the compliance of lung was as poor less as 5 mL/cm H2O, this patient was eventually rescued and recovered by extraprolonged extracorporeal membrane oxygenation support for 117 days.

Infrared ear thermometry in water-related accidents-not a good choice.

Hypothermia in near-drowning victims is a serious problem that impacts clinical decision-making. The purpose of this trial was to determine the reliability of tympanic temperature measurements compared to oral temperature measurements after immersion in water. After ethical approval was obtained, we studied oral and tympanic temperature in 25 volunteer swimmers (aged 18-49 years). Sublingual (Fixotherm; Tradesell Europe, Eglharting, Germany) and tympanic (First Temp Genius; Sherwood Medical, Sulzbach, Germany) temperature measurements were performed before entering the water, after 45 min of immersion in water, and 15 min after leaving the water. During the immersion phase, the ears were temporarily immersed. A control group (the same 25 volunteers) had to swim for the same amount of time without ever immersing their heads in the water. The trial was performed in an indoor swimming pool at 28 degrees C water and 30 degrees C air temperature. The oral temperature did not change over time in either group. The tympanic temperature was significantly lower after immersion compared to baseline in the "immersed" group (33.7 degrees C vs. 37.5 degrees C, p < 0.001), increased significantly in the recovery period, but remained significantly lower than baseline (36.0 degrees C vs. 37.5 degrees C, p < 0.001). At baseline, the oral temperature was lower compared to the tympanic temperature. This relationship reversed after immersion and remained reversed until the end of the trial in the immersion group. The control group maintained oral temperatures lower than tympanic throughout the study; furthermore, the control group had no clinically relevant change in oral or tympanic temperature over the time (tympanic temperature: 37.4 degrees C vs. 37.2 degrees C, p = 0.06). Our data suggest that in water-related accidents such as near drowning, the values of body (core) temperature obtained via use of infrared ear thermometry are unreliable, and should not be used for clinical decision-making.

A 10-month-old infant with reversible findings of brain death.

Death has occurred when there is irreversible loss of integration of the organism as a whole, and brain death is said to be a criterion for death. In the present case, a 10-month-old boy was found submerged in a bathtub and was given cardiopulmonary resuscitation for 37 minutes. He had received therapeutic dosing of phenobarbital and midazolam up to 5 hours prior to a brain death examination. He fulfilled all criteria for brain death according to Canadian Neurological Determination of Death Forum recommendations on an examination 42 hours after the drowning event, but started breathing another 15 hours later. Eleven previously published cases of purported reversal of findings of brain death are discussed here, including two infants who fulfilled all criteria for brain death for more than 24 hours. Recommendations for brain death determination may require revision for infants, to more clearly define a time interval between examinations and to incorporate consideration of confounding sedative drug effects. Together with previous reports, the present case calls into question the assumption that brain death as currently diagnosed is irreversible, and therefore equivalent to death of the patient.

[Traumatologic pediatric emergencies--part I: Injury, drowning and blunt abdominal trauma]. / Traumatologische Kindernotfälle (Teil I): Verbrennungen, Ertrinken und stumpfes Bauchtrauma.

Injuries are responsible for considerable morbidity and much long-term or permanent disability. They are also the leading cause of death for children aged 0 to 5. In high income countries around the world 20000 children die each year from injuries. A recent UNICEF report has compiled data for 2001 on the leading cause of death for Europe. The burden of disease measure has identified injury as causative in 40% of years lost from premature death in children. Drowning and near drowning is the number two killer for children aged 0 to 5. In 30% of all cases cardio-pulmonary resuscitation and intensive care are needed. 11.5% of all drowning accidents are fatal, 9.5% of nearly drowned children show extensive neurologic deficits. Though the absolute number of deaths from injury in children has decreased during the last 20 years (in 1980: 18.8 dead children per 100000; in 2004: 3.0 dead children in 100000), still approximately 400 children die from injuries in Germany every year. The public health approach to injury involves not only deaths but also the burden of disease and loss of health from disability. Severe traumatologic pediatric emergencies are thermal injury, drowning and blunt abdominal trauma.

Drowning in concentrated syrup.

Drowning is one of the two leading causes of accidental death in children. Most of the cases can be attributed to fresh or salt water drowning. We report an unusual case of acute respiratory distress syndrome in a one year old child following drowning in concentrated sugar syrup, in whom timely intervention and early supportive therapy resulted in a favorable outcome.

Prognostic value of proton magnetic resonance spectroscopy findings in near drowning patients: reversibility of the early metabolite abnormalities relates with a good outcome.

In two children with near drowning hypoxic encephalopathy and normal-appearing structural MRI, acute proton magnetic resonance spectroscopy ((1)H MRS) showed biochemical alterations that correctly indicated prognosis and helped to guide management decisions. Elevation of the lipid-lactate and glutamine-glutamate peaks, on the early (72 hour) (1)H MRS, predicts a poor prognosis. Absence of lipid-lactate and glutamine-glutamate peaks on the early (1)H MRS and reversibility of early mild metabolite abnormalities on follow up examination relates with good outcome.
