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.

Outcome after resuscitation beyond 30 minutes in drowned children with cardiac arrest and hypothermia: Dutch nationwide retrospective cohort study.

OBJECTIVES: To evaluate the outcome of drowned children with cardiac arrest and hypothermia, and to determine distinct criteria for termination of cardiopulmonary resuscitation in drowned children with hypothermia and absence of spontaneous circulation. DESIGN: Nationwide retrospective cohort study. SETTING: Emergency departments and paediatric intensive care units of the eight university medical centres in the Netherlands. PARTICIPANTS: Children aged up to 16 with cardiac arrest and hypothermia after drowning, who presented at emergency departments and/or were admitted to intensive care. MAIN OUTCOME MEASURE: Survival and neurological outcome one year after the drowning incident. Poor outcome was defined as death or survival in a vegetative state or with severe neurological disability (paediatric cerebral performance category (PCPC) ≥ 4). RESULTS: From 1993 to 2012, 160 children presented with cardiac arrest and hypothermia after drowning. In 98 (61%) of these children resuscitation was performed for more than 30 minutes (98/160, median duration 60 minutes), of whom 87 (89%) died (95% confidence interval 83% to 95%; 87/98). Eleven of the 98 children survived (11%, 5% to 17%), but all had a PCPC score ≥ 4. In the 62 (39%) children who did not require prolonged resuscitation, 17 (27%, 16% to 38%) survived with a PCPC score ≤ 3 after one year: 10 (6%) had a good neurological outcome (score 1), five (3%) had mild neurological disability (score 2), and two (1%) had moderate neurological disability (score 3). From the original 160 children, only 44 were alive at one year with any outcome. CONCLUSIONS: Drowned children in whom return of spontaneous circulation is not achieved within 30 minutes of advanced life support have an extremely poor outcome. Good neurological outcome is more likely when spontaneous circulation returns within 30 minutes of advanced life support, especially when the drowning incident occurs in winter. These findings question the therapeutic value of resuscitation beyond 30 minutes in drowned children with cardiac arrest and hypothermia.

[Reduction of the drowning risk for young children, but increased risk for children of recently immigrated non-Westerners]. / Afname van het verdrinkingsrisico bij jonge kinderen, maar verhoogd risico bij kinderen van recent geïmmigreerde niet-westerse allochtonen.

OBJECTIVE: To describe differences in the risk of drowning of young children (under 10 years) in the Netherlands according to ethnicity and relevant trends since 996. DESIGN: Retrospective. METHOD: We analysed the causes of death data for all 266 children aged 0 to 10 years who died of drowning between 1996 and 2005. Information for the cause of death was obtained from the cause of death data of Statistics Netherlands. Data about the size and composition of the population at risk (age, sex and ethnicity) were obtained from the municipal population registers. RESULTS: Young children's risk of drowning has decreased by about one-third since 1996. This decrease took place among native Dutch children and children of the major ethnic groups, notably Turkish, Moroccan and Surinamese. However for children of recently immigrated parents of non-Western ethnicity, mainly asylum seekers, the risk of drowning was 4 to 8 times higher than that of native children aged 3 to 10 years. CONCLUSION: Timely health education directed at newly arrived families with children could be an important measure to help them cope with the hazards of living in a water-rich environment such as the Netherlands. The education should point out the necessity of increased supervision of the youngest children and improved swimming skills for the slightly older ones.

A consensus process on management of major burns accidents: lessons learned from the café fire in Volendam, The Netherlands.

PURPOSE: The optimum response to the different stages of a major burns incident is still not established. The fire in a café in Volendam on New Year's Eve 2000 was the worst incident in recent Dutch history and resulted in mass burn casualties. The fire has been the subject of several investigations concerned with organisational and medical aspects. Based on the findings in these investigations, a multidisciplinary research group started a consensus study. The aim of this study was to further identify areas of improvement in the care after mass burns incidents. DESIGN/METHODOLOGY/APPROACH: The consensus process comprised three postal rounds (Delphi Method) and a consensus conference (modified nominal group technique). The multidisciplinary panel consisted of 26 Dutch-speaking experts, working in influential positions within the sphere of disaster management and healthcare. FINDINGS: In response to the postal questionnaires, consensus was reached for 66 per cent of the statements. Six topics were subsequently discussed during the consensus conference; three topics were discussed within the plenary session and three during subgroup meetings. During the conference, consensus was reached for seven statements (one subject generated two statements). In total, the panel agreed on 21 statements. These covered the following topics: registration and evaluation of disaster care, capacity planning for disasters, pre hospital care of victims of burns disasters, treatment and transportation priorities, distribution of casualties (including interhospital transports), diagnosis and treatment and education and training. ORIGINALITY/VALUE: In disaster medicine, the paper shows how a consensus process is a suitable tool to identify areas of improvement of care after mass burns incidents.

A new definition of drowning: towards documentation and prevention of a global public health problem.

Drowning is a major global public health problem. Effective prevention of drowning requires programmes and policies that address known risk factors throughout the world. Surveillance, however, has been hampered by the lack of a uniform and internationally accepted definition that permits all relevant cases to be counted. To develop a new definition, an international consensus procedure was conducted. Experts in clinical medicine, injury epidemiology, prevention and rescue from all over the world participated in a series of "electronic" discussions and face-to-face workshops. The suitability of previous definitions and the major requirements of a new definition were intensely debated. The consensus was that the new definition should include both cases of fatal and nonfatal drowning. After considerable dialogue and debate, the following definition was adopted: "Drowning is the process of experiencing respiratory impairment from submersion/immersion in liquid." Drowning outcomes should be classified as: death, morbidity, and no morbidity. There was also consensus that the terms wet, dry, active, passive, silent, and secondary drowning should no longer be used. Thus a simple, comprehensive, and internationally accepted definition of drowning has been developed. Its use should support future activities in drowning surveillance worldwide, and lead to more reliable and comprehensive epidemiological information on this global, and frequently preventable, public health problem.

Medical management after indoor fires: a review.

UNLABELLED: Fires involving mass burn casualties require extreme efforts and flexibility from the regular health care system. The café fire in Volendam, which occurred shortly after midnight on the first of January 2001, resulted in the worst indoor mass burns incident in Dutch history. During the extensive medical evaluation of this disaster, it became obvious that information on similar incidents is relatively scarce in the literature. This article systematically reviews the existing information in the medical literature on indoor fires and provides findings and knowledge used in the evaluation of the medical management after indoor fires and for future mass burn casualty preparedness, mitigation and response. METHODS: A literature review was undertaken for burn disasters with characteristics similar to the indoor Volendam fire disaster. In all fires, the following aspects were investigated: characteristics of the fire; the initial emergency response; triage and on-site treatment; primary and secondary distribution; hospital admission; severity of the sustained injuries and mortality. RESULTS: A total of nine similar indoor fires were selected. The number of people involved was reported in seven fires (range 137-6000). All reports provided the mortality rate (range 1.4% to over 50%). Data regarding the emergency response could be collected in half of the studies. On-scene triage was performed in five fires. The number of hospitals participating in the primary distribution ranged from 1 to 19. Except for the Volendam fire, all patients were primarily distributed to general hospitals. CONCLUSION: Characteristics of indoor fires, which are relevant for disaster preparedness, mitigation and response are not frequently reported in medical literature. The current articles on indoor fires, mainly report on numbers of casualties and the mortality. Limited data are available to provide insight in the characteristics of management and medical treatment and to come up with suggestions for improvement of future burn incidents management. The evaluation of disasters should be based on uniform methods and structured reports and effective record keeping is essential to achieve this.

The café fire on New Year's Eve in Volendam, the Netherlands: description of events.

AIM OF STUDY: The café fire at Volendam occurred shortly after midnight on the first of January 2001 and resulted in one of the worst mass burn incidents in recent Dutch history. The aim of this study was to provide insight into medical and organisational requirements of a major burns incident. METHODS: Shortly after the fire, two university hospitals and a burn center in the region of the accident developed a plan for evaluation of medical care given during and after this major burn incident. A multidisciplinary research group investigated the management of victims at the scene, in the emergency departments (ED) and during admission in the hospitals. All 245 casualties were included in this study. RESULTS: A brief severe fire occurred in a crowded cafe with around 350 young visitors on a small embankment of a relatively isolated town, resulting in a unusually high number of severely injured burn victims. Four died immediately. The ensuing rescue effort was hampered by poor access and chaotic circumstances. At the scene of the incident, mobile medical teams ensured orderly transport and treatment priority for the injured. There were 245 victims with a median total body surface area burned of 12%. Inhalation injury was present in 96 patients. A total of 182 victims were admitted, with 112 to intensive care. Ten patients died in the hospital. Seventy-eight patients were secondarily transported, many to specialised centers in the Netherlands and abroad. In total, 36 hospitals in three countries participated. CONCLUSION: An incident with high numbers of burn victims poses a challenge to any health care system. The difficult circumstances at the site demonstrated the need for robust organisational structures. The primary and secondary distribution of patients required coordination, general hospitals were able to provide initial medical care to these major burn casualties.

[International and Dutch reanimation guidelines]. / Internationale en nationale reanimatierichtlijnen.

The 'Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care' have been published in a number of journals by a group of international experts. Although these guidelines are not dictated or imposed, their implementation would necessitate changes to the curriculum 'Basic Life Support' instruction for laymen. The recall of all persons ever instructed to inform them about the new Guidelines is also necessary. However, in view of the present lack of solid scientific basis, the wisdom of implementing the present guidelines in Dutch practice in an unrestricted manner has to be questioned, due to financial and human impact that would be involved.

[Debriefing of hospital professional staff after fire in a bar in Volendam]. / Debriefing van ziekenhuismedewerkers na de cafébrand in Volendam.

A fire disaster in a bar on New Year's Eve 2001 in Volendam, which led to 200 victims, resulted in active participation of regional hospitals, including the academic hospital of the Free University of Amsterdam. In the first hour, more than 100 members of personnel were mobilised in this hospital. Nine doctors and nurses worked as members of medical teams at the site of the disaster; the others triaged 16 patients in the emergency room and treated 13 patients in the intensive care unit. After 4.5 hours, the influx of victims stopped and accordingly the disaster plan was deactivated. During the subsequent days, debriefings were organised on request of the hospital staff and personnel involved. These concluded that specific adjustments to hospital procedures were needed, such as a total admission stop for a few days, to prevent mental burn-out of personnel and to maintain the standard quality of care. Hospital disaster plans do not usually have specific guidelines for the emotional preparation of personnel during and immediately after a disaster, nor do they include specific guidelines for the evaluation of its emotional impact in terms of the quality of care delivered. These elements should be incorporated into every disaster plan.

Basic-CPR and AIDS: are volunteer life-savers prepared for a storm?

Professional health care workers have access to guidelines, equipment and techniques to reduce the exposure to infectious material in case of resuscitation. The current official content of national courses for volunteer life-savers do not address this issue, as far as we know. Concern about the risks of infection due to resuscitation is increasing in this group. This article describes a rational approach of the problem, that includes data on the infection risk of basic-CPR, and an approach that accepts that the concern can not be controlled by objective data. In such an emotional approach, direct contact has to be minimised by using devices. Requirements for resuscitation devices with a barrier function are listed. Although both approaches will reduce the fear of infection, we advice a rational approach.

Pulmonary oedema, pneumonia and mortality in submersion victims; a retrospective study in 125 patients.

OBJECTIVE: The identification of risk factors contributing to the development of pulmonary oedema, pneumonia and late mortality in submersion victims. DESIGN: A retrospective study of 125 submersion victims. SETTING: The medical intensive care unit in a university hospital. METHODS: Baseline examination on admission consisted of history, physical examination, arterial blood gas analysis and a chest radiograph. Patients were then classified into four groups: class I, baseline examination negative; class II, baseline examination positive, but mechanical ventilation not needed on admission; class III, mechanical ventilation required on admission; class IV, patients suffering from cardiopulmonary arrest. All patients who were not successfully resuscitated or who had expired within 24 h after admission were excluded for determination of the risk of pulmonary oedema and pneumonia. RESULTS: Class I patients did not develop pulmonary complications; neither pulmonary oedema nor pneumonia occurred in this group. In the remaining classes the incidence of pulmonary oedema was 72% and that of pneumonia, 14.7%. Stepwise logistic regression showed that pulmonary oedema was related to the type of water (seawater, ditch water, swimming pool) victims were submerged in and to the neurological state both at the time of rescue and on admission. The development of pneumonia was related to the use of mechanical ventilation (the risk was 52%). Pneumonia was not related to neurological state at the time of rescue or on admission, to body temperature on admission, to the prophylactic administration of antibiotics or to the use of corticosteroids. Mortality was high in class IV patients, but low in all other patients. Early mortality was 18.4% while late mortality was 5.6%. CONCLUSIONS: There is no need to hospitalise submersion victims when there are no signs or symptoms of aspiration upon arrival in the emergency room. All other patients should be admitted to an intensive care unit. The risk of pneumonia is high when mechanical ventilation is necessary. Mortality is high in patients with circulatory arrest on admission, but low in all other patients.

Accidental hypothermia: incidence, risk factors and clinical course of patients admitted to hospital.

This study was initiated to identify the incidence, risk factors and outcome predictors of patients admitted to hospital in the Netherlands because of accidental hypothermia. Information about these patients was available for study through the National Health Care Data Bank. Between 1987 and 1990, 612 accidental hypothermic patients were admitted: 185 hypothermic patients also suffered from submersion (HYPSUBS), but this was not the case in the remaining 427 patients (HYPNOTSUBS). Patients in the HYPNOTSUBS group were older (average age 55.2 years versus 38.9 years; p < 0.001), remained longer in hospital (average 20.8 days versus 9.2 days; p < 0.001) and had a higher death rate than those in the HYPSUBS group (16.9% versus 5.9%; p < 0.001). In HYPNOTSUBS, increasing age correlated with increases in the length of hospital stay and death rate. This relationship was not found in HYPSUBS. Trauma was the major associated problem in both groups; these patients had the highest death rate (22.8% versus 16.7%; not significant). Death occurred within 2 days in 54% of HYPNOTSUBS non-survivors and 73% of HYPSUB non-survivors. HYPNOTSUBS admitted to university hospitals showed a lower death rate (5.9%) compared with HYPNOTSUBS admitted to non-university hospitals with less than 400 beds (13.4%) or more than 400 beds (21.7%). In contrast, the death rate in HYPSUB was higher in university hospitals (14.3%) than in non-university hospitals with less than 400 beds (5.2%) or more than 400 beds (3.6%). We observed that the incidence of accidental hypothermia is low at 1.1 per 100,000 inhabitants per year. We concluded that HYPNOTSUBS and HYPSUB are different groups of patients with respect to demographic data, risk factors and prognostic factors. Old age is an important unfavourable prognostic factor in HYPNOTSUB but not in HYPSUB. Hypothermia with trauma is an unfavourable combination in both groups. Almost half of the HYPNOTSUBS non-survivors died after more than 2 days. Because body temperature will have returned to normal by then, this must be the result of late complications. Most HYPSUB non-survivors died during the first 2 days, probably as a direct result of the submersion injury.

Resuscitation skills of lay public after recent training.

STUDY OBJECTIVE: To investigate the ability of laypeople to apply basic CPR techniques after recent training. DESIGN: Cross-sectional assessment of practical CPR skills. TYPE OF PARTICIPANTS: 151 laypeople who were trained twice in the preceding 20 to 24 months. MEASUREMENTS AND MAIN RESULTS: Practical skills were tested using six primary recorded variables that describe the quality of CPR techniques in a training situation. A total score on the skills of each participant was computed on the basis of a predefined scoring system. Thirty-three percent of the participants were able to perform adequate CPR. The compression:relaxation ratio, the breathing volume, and the breathing interval were points of concern. CONCLUSION: Practical skills in basic CPR after a 12-month training interval, though better in this study than in many previous studies, are insufficient in the majority of laypeople. The results of this study could be used to design a better tailored (re)instruction program, with an emphasis on regular, frequent refresher courses.

[Submersion in children; the role of hypothermia and development of adult respiratory distress syndrome]. / Submersie bij kinderen; rol van hypothermie en ontstaan van 'adult respiratory distress'-syndroom.

OBJECTIVE: To evaluate the occurrence of the adult respiratory distress syndrome (ARDS), and of hypothermia as a predictor of outcome in cases of submersion injury in children. DESIGN: Retrospective analysis. PATIENTS: All drowning cases admitted to the Intensive Care Unit of the Wilhelmina Children's Hospital in Utrecht between January 1986 and January 1993. RESULTS: There were 45 patients, 29 boys and 16 girls, aged 0-13 years. Hypothermia was related to the duration of submersion and did not correlate with a good outcome. Asystole on arrival at the hospital was associated with demise in all but one patient, who was left with severe neurological impairment. ARDS occurred in 27/45 patients (60%), all within 6 h following admission. Of the 45 patients treated, 11 died. Of the 34 survivors, 7 were discharged from the Intensive Care Unit with neurological sequelae (2 with mild, 5 with serious sequelae). CONCLUSION: In our patients with drowning accidents, hypothermia did not appear to provide any protective effect. ARDS, if it occurred, became evident within 6 h after admission.

Submersion in The Netherlands: prognostic indicators and results of resuscitation.

STUDY OBJECTIVES: To analyze prognostic indicators and the outcome of resuscitation in submersion victims (drowning and near drowning). DESIGN: Retrospective study. SETTING: Intensive and Respiratory Care Unit. Between January 1, 1979, and December 31, 1985, 87 submersion victims were admitted. The files of 83 victims were available for statistical analysis. There were 66 male victims and 17 female victims; the average age was 31.4 +/- 25.8 years. There were ten salt water and 73 fresh water submersions. MEASUREMENTS AND MAIN RESULTS: Predictors for better survival potentials were a young age, submersion of less than ten minutes, no signs of aspiration, and a central body temperature of less than 35 C at admission. We did not detect factors that accelerated a decrease in core body temperature at admission and assume that lethal hypoxia had preceded protective hypothermia in our submersion victims. The Orlowski score had a predictive value but at the same time we found nonindependent indicators in this score. Neurologic outcome in our patients, who were not treated according to a brain protection protocol, was not worse than the outcome published by authors who have used such a protocol. Thirty-three percent of the victims with a cardioventilatory arrest (15) and all victims with a ventilatory arrest (11) survived resuscitation and were discharged. Five nonarrest victims died due to late complications. CONCLUSION: This study shows that no indicator at the rescue site and in the hospital is absolutely reliable with respect to death or survival.
