Where children drown, United States, 1995.

CONTEXT: Drowning is the second leading cause of unintentional injury death among children ages 1 to 19 years. Details about the specific site of submersion are important for implementation of primary prevention efforts, but are not routinely available from national data. OBJECTIVES: To provide national data about the specific sites of drowning among US children and to examine site-specific drowning rates by age, race, and gender. SETTING: United States, 1995. DESIGN: Information was abstracted from death certificates for unintentional drownings among children <20 years of age. The site of drowning was coded from free text on death certificates. Proportional distributions of the site of drowning by age, region, gender, and race were examined. Site-specific drowning rates were calculated by age, race, and gender. Denominators were based on US Census Bureau, June 1995 estimates of the US population. RESULTS: For 1995, death certificates were obtained for 1420 unintentional drownings among children <20 years of age, 98% of the number of drowning deaths reported by the National Center for Health Statistics for the same year. Site of drowning was specified on 1308 (92%) death certificates. Fifty-five percent of infant drownings were in bathtubs. Among children between the ages of 1 to 4 years, 56% of drownings were in artificial pools and 26% were in other bodies of freshwater. Among older children, 63% of drownings were in natural bodies of freshwater. Site-specific drowning rates varied by race. Importantly, after the age of 5 years, the risk of drowning in a swimming pool was greater among black males compared with white males with rate ratios of 15.1 (95% confidence interval: 6.7-38.5) among 10- to 14-year-olds and 12.8 (95% confidence interval: 6.5-26.9) among 15- to 19-year-olds. CONCLUSION: The variety of sites in which children drown, even within specific age groups, emphasizes the need for a multifaceted approach to prevention. Reductions in the relatively high rates of drowning among black adolescent males will require targeted interventions to prevent swimming pool drownings among this group.

How well does a national newspaper reporting system profile drowning?

In Finland, the Finnish Association for Swimming Instruction and Life Saving (SUH) and Statistics Finland (SF) both provide nationwide data on unintentional drowning. The SUH database relies on rapid reporting from a newspaper clipping service and additional local police information, whereas the SF database relies on the later release of the death certificate information, which is based on extensive medico-legal investigation. The aim of the study was to explore the main differences between the SUH and SF databases for drowning and to evaluate the capacity of the former to characterize drowning events in Finland from 1998 to 2000. Computerized files of death certificates tabulated by SF were linked with the SUH database by deterministic methods. SF and SUH databases allowed the identification of 704 and 567 unintentional drownings, respectively, giving an unintentional drowning rate of 4.5 and 3.6/100?000 per year. Of the 704 drownings described by SF, 418 (59.4%) were also found in the SUH database. The SUH database markedly underreported drowning fatalities in certain settings, such as bath, ditch and swimming pool drownings; fall- and land-traffic-related drownings; and drownings occurring in South Finland. The narrative text of SUH drownings contributed limited information to characterize the drowning events. It was concluded that the newspaper-based SUH data provide more timely data on individual drownings but are not representative of all drownings. Conversely, the SF vital statistics data are more accurate but may take up to 2 years to become available. Both SUH and SF data provide little detailed information on drowning events. A multidisciplinary national surveillance system for drowning is necessary to provide more accurate and timely drowning data, analyse risk factors and design follow-up studies for developing and monitoring prevention strategies.

Systematic review of definitions for drowning incidents.

OBJECTIVES: In preparation for the World Congress on Drowning uniform reporting consensus document of drowning incidents we reviewed systematically the medical literature for the terms and definitions used to describe drowning incidents to assess the uniformity of these terms in the medical literature. METHODS: The search strategy included a literature search of PubMed, MEDLINE and the Cochrane Database from 1966 to April 2002, as well as a review of reference lists of identified studies and a hand search of relevant textbooks and reference works. Search terms used included drowning, near-drowning, submersion, immersion, suffocation, asphyxiation, water injuries, and aspiration. Any article with drowning as a primary focus and containing a definition of drowning was included. Study designs included experimental studies, observational studies, case control studies, reviews, letters, and editorials. RESULTS: The search identified approximately 6000 articles. Of these 650 were reviewed and 43 articles addressing the definition of drowning were identified. We found a total of 33 different definitions to describe drowning incidents, 20 for drowning and 13 for near-drowning; along with another 13 related terms. There were at least 20 different outcome measures for drowning incidents reported. CONCLUSIONS: A review of existing drowning literature demonstrates a lack of a standard definition of drowning and a lack of agreement on measures of outcome. This variability in definitions and outcomes makes it very difficult to assess and analyze studies both individually and as a whole and draw conclusions that will influence practice. These objective findings support the need for the drowning Utstein focus on one definition of drowning and validated measures of functional and neurological outcome.

Patterns of drowning in Australia, 1992-1997.

OBJECTIVE: To determine patterns of victims, circumstances and locations of drownings in Australia in 1992-1997, inclusive. METHODS: Population figures and available details of all drownings were obtained from the Australian Bureau of Statistics. Accidental non-boating drownings (ICD E910), boating incidents (E830-832), homicide (E964), suicide (E954), and other deaths without a drowning E code but "flagged" because drowning was involved (although not the primary cause of death) were included. RESULTS: The overall accidental non-boating drowning rate was 1.44/100,000 population/year. The commonest sites for non-boating drowning were ocean or estuary (22%), private swimming pools (17%), non-tidal lakes and lagoons (17%), surfing beach (10%) and bathtub (7%). 22% of victims were aged under 5 years; this group had a drowning rate of 4.6/100,000 population/year. Very few young children drowned in the ocean or in boating incidents. The rate of boating drownings was 0.29/100,000 population/year. Overseas tourists comprised 4.7% of all non-boating drownings, 18% of surf and ocean drownings, and 25% of all scuba drownings. Indigenous people had a much higher drowning rate than the general population. CONCLUSIONS: Drownings in children aged less than 5 years continue to be the greatest challenge for water safety organisations and legislators. Drownings in the Indigenous community and among tourists requires more detailed study and action. To assist in developing preventive strategies, the National Water Safety Council will need to clarify the categories described as "ocean/estuary" and "lake, lagoon, dam and waterhole".

The epidemiology and prevention of drowning in Singapore.

INTRODUCTION: The aim of this study was to derive a profile of drowning victims in Singapore in the 10-year period 1992-2001 and determine if there are any patterns, trends or factors which may affect the risk profile of victims. Another objective was to recommend measures for reducing deaths from drowning through a review of some of the current literature and studies on drowning prevention. METHODS: Data for epidemiological analysis were studied and analysed. Data was primarily obtained from the annual drowning statistics reported in the annual reports of the Singapore Life Saving Society, which were in turn obtained from the Registry of Births and Deaths, and the Coroner's Court. The review of current literature and studies on drowning was concentrated on the publications of leading drowning experts and agencies and on the papers presented at two important international conferences, the International Drowning Symposium in May 1996 and the first World Congress on Drowning in June 2002. The review was done with a view to identify successful drowning prevention measures that may be adopted or enhanced in Singapore. RESULTS: The study revealed a few important findings. Firstly, Singapore had a drowning rate per 100,000 population that varied from a low of 0.88 in one year to a high of 1.72 in another in the period 1992-2001. Secondly, the male drowning mortality rate in Singapore was much higher than the female drowning mortality rate. Thirdly, persons in the age group of 20-29 years were at the highest risk. Fourthly, the sea, rivers and swimming pools were the locations with the highest number of drowning victims. The study also showed that the main measures of drowning prevention may be broadly divided into supervision, environmental design changes, legislation, swimming lessons and aquatic safety education. CONCLUSION: The situation in Singapore is generally comparable to that in high income or developed countries although there are some differences. Further studies and research need to be done to provide a better understanding of the epidemiology and prevention of drowning in Singapore. In the meantime, the main measures of drowning prevention should, as far as possible, be followed or enhanced.

Drowning awareness. Prevention and treatment.

BACKGROUND: Drowning is a common, preventable problem, especially in childhood where it is the second most common cause of death by accident in Australia, with 0-4 year olds comprising 22% of all drownings. Commonest sites for drowning are nontidal lakes and lagoons; private swimming pools (especially preschool children); ocean/estuary and surfing beaches; bathtub and bucket drownings (especially in infants and toddlers with up to 10% of bucket drownings due to child abuse). OBJECTIVE: This article reviews the current information on the epidemiology, prevention and treatment of drowning. DISCUSSION: Despite prevention strategies, including pool fencing, drowning rates in young children have remained relatively static. In older children, drowning rates have declined dramatically despite the lack of prevention. The indigenous population have a much higher rate of drowning than the overall figure and their toddler rate is very high. Approximately 69% of near drowning victims will have complete neurological recovery, 28% will suffer some selective deficit, and 3% survive in a permanent vegetative state. Alcohol has been strongly implicated in drowning and banning alcohol from adjacent swimming areas has reduced drowning rates. Overseas tourists were 4.7% of all nonboating drownings in Australia with 89% of these drowning in the ocean. Further funding for drowning prevention strategies are essential, yet noticeably lacking.

Drowning in Finland: "external cause" and "injury" codes.

BACKGROUND: The International Classification of Diseases (ICD) external codes (E codes) for drowning assist in determining the primary event leading to drowning, but do not alone allow the precise determination of the overall drowning rates. AIMS: To analyze the sensitivity of the ICD E codes for drowning. To describe the pattern and trend of drowning deaths that are classified with E codes other than for drowning. SETTING: Finland, 1969-2000. METHODS: Mortality files of Statistics Finland were searched electronically using the injury codes (I codes) and E codes for drowning. Cross analysis of I and E coded drownings was performed to determine the rate and pattern of drowning cases classified with E codes other than for drowning. Time trends were calculated using the Poisson regression model. RESULTS: Of 13 705 drowning deaths, 644 (4.7%) were not identified with the E codes for drowning. The great majority (n=547, 84.9%) of these cases were traffic accidents resulting in drowning. No significant time trends were found even after the introduction, in 1996, of the ICD 10th revision. CONCLUSIONS: In Finland, underestimation of overall drowning rates using the E code alone is less pronounced than in countries where similar studies have been performed. The relatively high rate of transport accidents resulting in drowning indicates a specific target for preventive countermeasures.

Pool fencing for preventing drowning in children.

BACKGROUND: In most industrialized countries, drowning ranks second or third behind motor vehicles and fires as a cause of unintentional injury deaths to children under the age of 15. Death rates from drowning are highest in children less than five years old. Pool fencing is a passive environmental intervention designed to reduce unintended access to swimming pools and thus prevent drowning in the preschool age group. Because of the magnitude of the problem and the potential effectiveness of fencing we decided to evaluate the effect of pool fencing as a drowning prevention strategy for young children. OBJECTIVES: To determine if pool fencing prevents drowning in young children. SEARCH STRATEGY: We used Cochrane Collaboration search strategy of electronic databases, searched reference lists of past reviews and review articles, Cochrane International Register of RCT's, studies from government agencies in the United States and Australia, and contacted colleagues from International Society for Child and Adolescent Injury Prevention, World Injury Network, and CDC funded Injury Control and Research Centers. SELECTION CRITERIA: In order to be selected a study had to be designed to evaluate pool fencing in a defined population and provide relevant and interpretable data which objectively measured the risk of drowning or near drowning or provided rates of these outcomes in fenced and unfenced pools. The completed studies meeting selection criteria employed a case-control design. No randomized controlled studies have been identified. DATA COLLECTION AND ANALYSIS: Three published studies met selection criteria. Data were extracted by two reviewers using standard abstract form. Odds ratios with 95% CI, and incidence rates, were calculated for drowning and near-drowning. Attributable Risk percent (AR%) was calculated to report the reduction in drowning due to pool fencing. MAIN RESULTS: Case control studies which evaluate pool fencing interventions indicate that pool fencing significantly reduces the risk of drowning. Odds ratio for the risk of drowning or near drowning in a fenced pool compared to an unfenced pool is 0.27 95%CI (0.16, 0.47). Isolation fencing (enclosing pool only) is superior to perimeter fencing (enclosing property and pool) because perimeter fencing allows access to the pool area through the house. Odds ratio for the risk of drowning in a pool with isolation fencing compared to a pool with three sided fencing is 0.17 95%CI (0.07, 0.44) REVIEWER'S CONCLUSIONS: Pool fences should have a dynamic and secure gate and isolate (i.e., four-sided fencing) the pool from the house. Legislation should require isolation fencing with secure, self-latching gates for all pools, public, semi-public and private.

Trends in suicide by drowning in the elderly in England and Wales 1979-2001.

BACKGROUND: Suicide by drowning increases with age but its rates vary between countries and among communities. Drowning suicide rates in some of the available studies may have been over reported or under reported because of misclassification. OBJECTIVE: This study presents data on the time trends, age/sex mortality rates from death by drowning in the elderly in England and Wales between 1979 and 2001. All coroners' verdicts in death by drowning; suicide, deaths undetermined whether accidentally or purposely inflicted were examined. METHODS: Counts of suicide due to drowning and submersion [ICD 9 codes; E954] and undetermined injury deaths [E984] (WHO, 1977), reported in England and Wales between 1979 and 2001 were obtained from National Statistics (ONS). RESULTS: There has been a gradual reduction in suicide by drowning in men and women by more than a third the observed count in 1979 (p < 0.01). However, this decline was less evident in the elderly particularly those over the age of 75. Elderly drownings appear to attract more verdicts of suicide compared to younger age groups (Odds Ratio 4.3 95% CI 2.3-8.3). Women, particularly elderly, are more likely to have a suicide verdict returned in drowning compared to men (Odds Ratio 1.5 95% CI 1.1-1.6). CONCLUSIONS: The high rate of open verdicts in elderly drowning over the study period and compared to any other method of fatal self harm in England and Wales confirms the difficulties in reaching a firm conclusion in drowning death. Therefore combining suicide and all undetermined deaths in drowning as a matter of course, in nationally collected statistics, may result in grossly exaggerated rates and misleading trends in suicidal drowning. Suicide by drowning is probably not amenable to prevention and although the elderly are often thought to benefit more from suicide prevention than younger adults, the study findings seem to suggest that this is not likely to be the case in drowning.

Unintentional drowning in Finland 1970-2000: a population-based study.

BACKGROUND: While standard data on drowning reported by the World Health Organization (WHO) fails to provide a reliable picture of the burden of drowning in Finland, they suggest that the rates are much higher than those of other industrialized countries. AIM: To determine the true burden of drowning in Finland and factors related to its high rates. DESIGN: Descriptive, retrospective, population-based analysis of all deaths by drowning, among residents of all ages. SETTING: Finland, 1970-2000. MATERIAL AND METHODS: Mortality and population data furnished by Statistics Finland (SF) were used to determine age- and sex-specific drowning mortality rates using both nature- and cause-of-injury codes. Individual-level data from the death certificates were analysed and cross-linked to a nationwide postmortem toxicology database. RESULTS: From 1970 to 2000, 9279 unintentional drownings occurred (mean: 299.3/year SD 84.3, rate 6.1/100 000/year; M:F ratio = 8.6:1), accounting for 11.7% of all unintentional injury deaths. Drowning rates overall have decreased from 9.9/100 000/year in 1970-1972, to 4.5 in 1998-2000 (-2.7%/year; 95% CL: -3.0; -2.5). The most frequent activities related to drowning included boating (29.8%), falling (26.1%), swimming (25.0%), and activities on ice (12.4%). In non-boating-related drownings, 74.5% of males and 67.4% of females tested had a blood alcohol concentration (BAC) >/=50 mg/dl, while in boating-related drownings, the respective values were 78.1% and 71.4%. CONCLUSIONS: WHO statistics underestimate the true burden of drowning in Finland by up to 40-50%. Drowning rates and alcohol involvement in drowning are much higher than in other comparable developed countries. Broad-based countermeasures to reduce alcohol use in water activities are needed as part of any strategy to reduce drowning rates.

Electrolyte analysis in pleural effusion as an indicator of the drowning medium.

In medico-legal autopsies for drowned bodies, the location of drowning needs to be determined. To investigate the usefulness of electrolyte analysis in pleural effusion as an indicator of the location where the deceased has drowned, we determined the concentrations of electrolytes in the pleural effusion of rats drowned in four kinds of water. The concentrations of sodium and chloride ions in the pleural effusion of rats that drowned in seawater were significantly greater than those of rats that drowned in freshwater at both 1 day and 3 days after drowning. The concentration of potassium ions in pleural effusion 1 day after drowning showed no difference between each group, although it then increased from 1 to 3 days after seawater drowning, whereas it decreased from 1 to 3 days after freshwater drowning. The concentration of total protein in pleural effusion increased from 1 to 3 days after drowning, however, there was no significant difference in the concentration of total protein in pleural effusion between each group at either 1 day or 3 days after drowning. These results suggest that analysis of electrolytes in pleural effusion may be useful for determining whether drowning has occurred in seawater or in freshwater.

The epidemiology of drowning worldwide.

The purpose of this analysis was to quantify the magnitude of death and disability from drowning and near-drowning worldwide and to provide epidemiological data on which to base prevention efforts. All data are from the Global Burden of Disease 2000 (Version 1) estimates in which deaths and disabilities are based on the WHO International Classification of Diseases. Extrapolations were made by age, sex, and WHO region. The six WHO regions of the world were further divided into high-income, and low- and middle-income based on the 1998 World Development indicators. According to the GBD 2000 data, an estimated 449,000 people drowned worldwide (7.4 per 100,000 population) and a further 1.3 million Disability Adjusted Life Years (DALYs) were lost as a result of premature death or disability from drowning. 97% of drownings occurred in low- and middle-income countries. Although 38% of drownings occurred in the Western Pacific Region, Africa had the highest drowning mortality rate (13.1 per 100,000 population). Males had higher drowning mortality rates than females for all ages and in all regions. Children under the age of 5 years had the highest drowning mortality rate for both sexes in all of the WHO regions except for Africa, where children aged 5 to 14 years had the highest mortality rate. Worldwide, for children under the age of 15 years, drowning accounted for a higher mortality rate than any other cause of injury. Drowning is a significant problem worldwide particularly for children under the age of 15 years. Low- and middle-income countries have the highest rates of drowning and account for more than 90% of such fatalities. Primary prevention efforts should thus be focused on these countries where many children who cannot swim drown in large bodies of water.

Drowning surveillance: how well do E codes identify submersion fatalities.

OBJECTIVES: The aim was to determine in New Zealand: (1) to what degree the International Classification of Diseases Supplementary Classification (ICD) external cause (E) codes for drowning identify all deaths involving drowning; (2) how the other drowning deaths are distributed across E codes; and (3) whether the proportion of drownings not identified by traditional ICD E codes has changed over time. METHODS: Mortality files for the period 1977-92, which were coded in the range E800-E999 (external causes of injury and poisoning), were searched electronically using the keyword "drown". RESULTS: 2718 cases that involved drowning were identified. This represents a 17.7% increase in the number of cases one would identify using ICD drowning E codes alone. The majority (65%) of the 408 drownings not coded as such were coded as motor vehicle traffic crashes. The number of drownings that were not identified by ICD E codes remained relatively constant over time, although the number of deaths E coded as drowning declined significantly in recent years. CONCLUSION: Standard ICD E codes for drowning do not identify all drowning related deaths, which may make comparisons of injury rates between countries difficult, especially for injuries such as drownings and burns that can be both nature of injury and external cause codes. Multiple cause coding and the inclusion of free text narratives are an important tool to improve the value of a country's vital statistics for injury prevention, and facilitate comparisons with other countries.

Characteristics of drowning by different age groups.

CONTEXT: While it is known that the risk of unintentional drowning varies with age, the manner in which drowning episode characteristics vary by age has not been well described. Such information might be useful for prevention. OBJECTIVE: To describe characteristics of drowning by age group. DESIGN: Retrospective review of the characteristics of drowning victims and their drowning incidents obtained from death certificates, medical examiner, pre-hospital, emergency department, and hospital records. SETTING: Three counties in Western Washington state. SUBJECTS: Residents who died (n=709) of unintentional drowning within the study region during 1980 through 1995. OUTCOMES: Age specific counts, proportions, and rates per million person years were estimated for and compared among six age groups. RESULTS: Rates varied by age group: 0-4 (30.5), 5-14 (11.6), 15-19 (29.9), 20-34 (21.5), 35-64 (12.5), and 65 years or older (21.2). Among those 0-4 years, the proportions that drowned in pools, bathtubs, and open water were nearly equal. But from age 5-64 years, over 69% of deaths were in open water. Among those 65 years and older, the deaths were almost evenly divided between bathtub and open water; bathtub drowning rates were highest in this age group, 10.9. Pre-drowning activities were divided into boating, swimming, car passenger, bathing, and fell in while doing something else. Most (64/89, 76%) victims aged 0-4 years drowned while bathing or after falling in. Among those 15-19 years, most occurred while swimming (24/79, 34%) or boating (22/79, 31%). The drowning event was least often witnessed among those 0-4 years (10/36, 28%), and most often witnessed (44/58, 76%) among those 15-19 years. Medical care (pre-hospital, emergency department, or hospital) was most often involved in drownings of those 0-4 years (70/89, 79%) and least among those over 65 years (11/86, 13%). CONCLUSION: The characteristics of drowning episodes vary greatly by age. Different prevention strategies may be needed for different age groups.

[Drowning in Israel--1990-1992].

There are no epidemiological studies of drowning in Israel in the scientific literature, despite prominent reports in the media. We analyzed the extent of mortality from drowning in Israel during 1990-92, attempting to identify and characterize groups at high risk, and to determine trends and differences between Israel and other countries. Computerized death certificate files were provided by the Israel government Central Bureau of Statistics; deaths from drowning were included among external causes codes E-830, 832, E-910, E-954, E-964, E-984. In Israel, as in the United States, mortality from drowning is the fourth cause of death among all unintentional causes, and the second cause in age-groups 1-24, ranking after transport accidents. During 1990-92 there were 1.2 drownings a year/100,000 population. The highest rates were found among young non-Jews 15-24 years old (7.8/100,000) and among elderly Jews (3.5/100,000). Unintentional drowning accounted for 89% of all deaths; while about 10% were defined as suicides. Males had a rate almost 3 times greater than females, and the among Arabs was 2.4 times greater than among Jews. The 1990-92 drowning rate was slightly lower than in previous years. Drowning rates in Israel are lower than in the United States, except in the elderly. Apparently the principal reason for this difference is difference in sites of drowning. In Israel most drownings occur in the sea, so site data are unavailable for international comparisons. Careful consideration of the categories (E-codes) included in the rates, and of local registration procedures, is necessary for international comparisons. Foreign workers, tourists and other nonresidents are not included in national vital statistics. But estimations based on Ministry of Interior sources show that foreign workers (most, recent arrivals) during the last few years are an extremely high risk group. Population-based drowning rates are not an accurate estimation of drowning risk, since universal exposure to the "opportunity to drown" is assumed.

Drowning. Rescue, resuscitation, and reanimation.

Several myths about drowning have developed over the years. This article has attempted to dispel some of these myths, as follows: 1. Drowning victims are unable to call or wave for help. 2. "Dry drownings" probably do not exist; if there is no water in the lungs at autopsy, the victim probably was not alive when he or she entered the water. 3. Do not use furosemide to treat the pulmonary edema of drowning; victims may need volume. 4. Seawater drowning does not cause hypovolemia, and freshwater drowning does not cause hypervolemia, hemolysis, or hyperkalemia. 5. Drowning victims swallow much more water than they inhale, resulting in a high risk for vomiting spontaneously or on resuscitation. No discussion of drowning would be complete without mentioning the importance of prevention. Proper pool fencing and water safety training at a young age are instrumental in reducing the risk for drowning. Not leaving an infant or young child unattended in or near water can prevent many of these deaths, especially bathtub drownings. Also crucial is the use of personal flotation devices whenever boating. Proper training in water safety is crucial for participation in water recreation and sporting activities, including SCUBA diving. The incidence of pediatric drowning deaths in the United States has decreased steadily over the past decade, perhaps as a result of increased awareness and attention to drowning-prevention measures (Box 1).

Study of the diagnostic value of iron in fresh water drowning.

The aim of our study was to test the diagnostic value of iron (Fe) in fresh water drowning by investigating the postmortem levels of hemodilution in drowning cases compared to control cases. Twenty-six typical fresh water drowning cases were selected from 128 immersion cases autopsied in our Department of Forensic Pathology between 1998 and 2004. The exclusion criteria were a long postmortem interval and other causes of death than drowning. For all selected cases, the diagnosis of drowning was based on the presence of autopsy findings and positive diatom test. A control population of 12 cases was also selected. For each drowning and control case, iron blood levels were measured in the left ventricle (LV) and right ventricle (RV) of the heart. The mean difference of iron concentration (RVFe-LVFe) between the drowning group and the control group was statistically compared. Furthermore, iron measurements were performed in 19 drowning cases showing advanced putrefaction. The mean difference of iron concentration was significantly higher in the drowning cases compared with controls (P<0.001). All drowning cases showed hemodilution. No overlap was found in the RVFe-LVFe levels between the two groups. Resuscitation attempts seemed to have no effect on the results. In cases of drowning showing advanced putrefaction, the iron test was not reliable because biochemical iron measurement was often prevented by no sufficient blood in the heart or postmortem clots. In conclusion, according to our results, iron seems to be a good biochemical marker in fresh water drowning with a short postmortem interval.

Epidemiology of child deaths due to drowning in Matlab, Bangladesh.

BACKGROUND: Although the recent decline in child mortality in Bangladesh is remarkable, death from causes other than infectious diseases and malnutrition remains an important component of child mortality. Death from drowning of children can be expected to be a problem in Bangladesh given the geographical features of the country. OBJECTIVE: The objectives of this study are to determine the trend, pattern, and correlates of drowning deaths. METHODS: Data are presented on deaths of children (1-4 years) due to drowning derived from a longitudinal, population-based surveillance system in operation in a rural area of Bangladesh in 1983-1995. Moreover, a case-control study was carried out to identify the risk factors associated with drowning. RESULTS: Deaths due to drowning ranged from about 10% to 25% of child deaths during 1983-1995. The absolute risk of dying from drowning remained almost the same over the study period but the proportion of drownings to all causes of death has increased. Drowning is especially prevalent in the second year of life. Age of the mother and parity have a significant impact on drowning. The risk of dying from drowning increases with the age of mother and much more sharply with the number of living children in the family. Two socioeconomic variables did not have an influence on the risk of drowning. CONCLUSIONS: A substantial proportion of child deaths could be averted if parents and other close relatives paid more attention to the safety of children. The Child Health Programme of the Ministry of Health and Family Welfare of Bangladesh should develop health education programmes for villagers alerting them to the dangers of drowning and measures to prevent it.
