Review
Perfect, uninterrupted basic life support (BLS) is the key for successful cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OHCA). Time plays an important role in the treatment of OHCA. This applies both to the time until the start of BLS and the reduction of all pauses during resuscitation, especially chest compressions. In 2022, the rate of bystander-CPR showed an absolute increase of 4% compared to previous years. The bystander-CPR rate is currently above 50%. Compared to OHCA in adults, cardiac arrest in children is rare in Germany. In the period from 2007 to 2021, the incidence was 3.08 per 100000 children. In addition, the etiology in children varies depending on the age group. While hypoxia is often the cause of circulatory arrest in younger children, trauma and drowning accidents are the main causes in school-age children. Different additional diagnostic and therapeutic strategies have been evaluated over the last years. Point-of-care ultrasound during resuscitation should only be performed by experienced users. Interrupting chest compressions and thus prolonging the no-flow phases must be avoided. Double sequential external defibrillation after the third shock can successfully terminate refractory ventricular fibrillation. While further studies are needed, emergency medical systems should train their teams to avoid complications. In refractory OHCA, extracorporeal CPR should be considered. In the case of in-hospital cannulation, immediate transport should be weighed against impaired chest compression quality. Therefore, transportation under CPR is only beneficial if there is an indication for further treatment.

BACKGROUND
World Health Organization (WHO) has classified drowning as a major public health problem. The most vulnerable victims of drowning are children from low and middle-income countries. Previously, it was the primary cause of death among children aged between 1 and 17 years in Bangladesh.
AIMS
This study explored the surrounding circumstances and associated factors of child drownings in Bangladesh.
METHODS
A qualitative phenomenological approach has been used to conduct the study. Bangladesh was chosen as the study area, and data were gathered using a semi-structured, open-ended questionnaire. Using convenience and snowball sampling methods, we have collected data from Dhaka and seven additional districts in Bangladesh. We reached a total of 44 individuals, where 22 agreed to participate in an interview (face-to-face and online interviews). The remaining 22 participants were selected in two focus group discussions via the web platform "ZOOM cloud meeting."
RESULTS
Our investigation revealed several factors associated with child drowning, including a lack of adequate parental supervision and monitoring, geographic locations and environment, seasonal factors, low living standards, peer pressure and risky behaviors, social stigma and prejudices, and natural disasters and calamities. According to our findings, a lower socioeconomic position is linked to a higher risk of nonfatal drowning. Moreover, this research also indicates a substantial nexus between child drowning fatalities and the socioeconomic conditions of the families of the victims.
CONCLUSION
The study adds to the existing body of knowledge by underlining the associated factors of child drowning fatalities in Bangladesh, which will aid in developing preventive policies. An essential aspect of any drowning prevention program for Bangladesh should be enhanced for community awareness of safe water rescue and resuscitation practices.

The South East Asian region has the world's second highest fatal drowning burden. This study reports analysis of survey data from representatives from nations within the Association of South East Asian Nations regarding current efforts, challenges and future opportunities for drowning prevention. Twenty-two responses were received from respondents from all ASEAN nations excepting Cambodia and Myanmar. Drowning prevention initiatives varied across ASEAN nations, with most efforts focused on public education and raising awareness, including the provision of drowning data to the media. The lack of comprehensive, national level data collection was identified as a challenge, necessitating strengthened data collection capacity. Governmental involvement spanned one to six different ministries, highlighting the multi-sectoral nature of drowning prevention. However, a lead ministry could be identified in only two countries. Despite the challenges identified, there remain many opportunities to strengthen drowning prevention across ASEAN nations, addressing a significant regional public health threat.

BACKGROUND
Future warming is projected to increase the heat-related mortality burden, especially for vulnerable populations. However, most previous studies focused on non-accidental morbidity or mortality, with far less research on heat-related accidental events.
METHODS
We collected individual accidental death records among all residents in Chinese mainland from June to August during 2013-2019. Accidental deaths were further divided into several subtypes by different causes. We used an individual-level, time-stratified, case-crossover study design to estimate the association between daily mean temperature and accidental deaths, and estimate its variation in seven geo-climatic zones, age (5-64, 65-74, ≥75), and sex (male, female). We then estimated the temperature-related excess accidental deaths under global warming scenarios of 1.5, 2, and 3℃.
FINDINGS
A total of 711,929 accidental death records were included in our study. We found that higher temperatures were associated with increased risks of deaths from the total accidental events and four main subtypes, including traffic, falls, drowning, and unintentional injuries. We also found that younger individuals (ages 5-64) and males faced a higher risk of heat-related mortality due to total accidents, traffic incidents, and drowning. For future climate scenarios, even under the 1.5℃ climate change scenario, 6,939 (95% eCI (empirical Confidence Interval): 6,818-7,067) excess accidental deaths per year are attributed to higher summertime daily temperature over mainland China, and the number of accidental deaths would increase by 16.71% and 33.59% under the 2℃ and 3℃ climate change scenarios, respectively. For residents living in southern coastal and northwest inland regions, the projected increase in accidental death is higher.
CONCLUSIONS
This nationwide study confirms that higher summer temperatures are linked to an increased risk of accidental deaths. Younger age groups and males face a higher risk. This indicates that current estimates of the health effects of climate change might be underestimated, particularly for younger populations.

BACKGROUND
Drowning is a major cause of death in Uganda, especially among young adults with water-based occupations and livelihoods. Information about drowning and other water-related deaths and injuries is limited. To address this gap in knowledge, study partners assessed knowledge, attitudes and beliefs about drowning and drowning prevention interventions in the Mayuge district of eastern Uganda.
METHODS
This study consisted of a mixed-methods, cross-sectional community health assessment. Research was conducted in 10 landing sites of 6 subcounties within Mayuge district bordering Lake Victoria and focused on 505 head-of-household interviews, 15 key informant interviews, 10 landing site observations and 3 focus group discussions with 10 young adults each.
RESULTS
While landing site observations revealed high lake use, households reported limited community drowning prevention knowledge and revealed risky behaviours and attitudes towards water safety. Less than one-third (30.9%) of participants reported that at least one family member can swim. 64.2% of all respondents reported no existing safety measures (eg, signage, fences) around the lake and 95.8% reported no aquatic emergency response system in their community. The majority of households (85.7%) had experienced a drowning incident in their area. Key informants and focus group participants were eager for community-based interventions and offered solutions that reflected international drowning prevention recommendations.
CONCLUSIONS
The results reveal gaps in services, access and knowledge and highlight a need for water safety services and interventions in lakeside communities in Uganda and throughout the Lake Victoria Basin.

BACKGROUND
Accurate, reliable, and sufficient data is required to reduce the burden of drowning by targeting preventive measures and improving treatment. Today's drowning statistics are informed by various methods sometimes based on data sources with questionable reliability. These methods are likely responsible for a systematic and significant underreporting of drowning. This study's aim was to assess the 30-day survival of patients with out-of-hospital cardiac arrest (OHCA) identified in the Danish Cardiac Arrest Registry (DCAR) after applying the Danish Drowning Formula.
METHODS
This nationwide, cohort, registry-based study with 30-day follow-up used the Danish Drowning Formula to identify drowning-related OHCA with a resuscitation attempt from the DCAR from January 1st, 2016, through December 31st, 2021. The Danish Drowning Formula is a text-search algorithm constructed for this study based on trigger-words identified from the prehospital medical records of validated drowning cases. The primary outcome was 30-day survival from OHCA. Data were analyzed using multiple logistic regression.
RESULTS
Drowning-related OHCA occurred in 374 (1%) patients registered in the DCAR compared to 29,882 patients with OHCA from other causes. Drowning-related OHCA more frequently occurred at a public location (87% vs 25%, p < 0.001) and were more frequently witnessed by bystanders (80% vs 55%, p < 0.001). Both 30-day and 1-year survival for patients with drowning-related OHCA were significantly higher compared to OHCA from other causes (33% vs 14% and 32% vs 13%, respectively, p < 0.001). The adjusted odds ratio for 30-day survival for drowning-related OHCA and other causes of OHCA was 2.3 [1.7-3.2], p < 0.001. Increased 30-day survival was observed for drowning-related OHCA occurring at swimming pools compared to public location OHCA from other causes with an OR of 11.6 [6.0-22.6], p < 0.001.
CONCLUSIONS
This study found higher 30-day survival among drowning-related OHCA compared to OHCA from other causes. This study proposed that a text-search algorithm (Danish Drowning Formula) could explore unstructured text fields to identify drowning persons. This method may present a low-resource solution to inform the drowning statistics in the future.
REGISTRATION
This study was registered at ClinicalTrials.gov before analyses (NCT05323097).

INTRODUCTION
Drowning is defined as the process of experiencing respiratory impairment from submersion or immersion in liquid. It is the third leading cause of unintentional injury-related deaths worldwide, accounting for 7% of all injury-related deaths.1 Our group sought to improve resident education regarding the basics of water safety and rescues as an event developed by our wilderness medicine (WM) interest group. With the growing number of WM Fellowships, specialty tracks, interest clubs and the regular inclusion of WM topics in residency didactics, exposure to WM topics has increased greatly.2 There is a large overlap between wilderness medicine and the field of emergency medicine. Both require stabilization, improvisation, and the treatment of environmental/exposure illnesses. It is imperative that emergency medicine physicians understand the complex pathophysiology of drowning, as well as recognize and manage potential associated traumatic injuries including fractures and critical hemorrhage. Our goal is to provide additional curricular instruction on prehospital management of water-related emergencies and related injuries to emergency medicine residents.
EDUCATIONAL OBJECTIVES
By the end of the session, the learner will be able to: 1) describe the pathophysiology of drowning and shallow water drowning, 2) prevent water emergencies by listing water preparations and precautions to take prior to engaging in activities in and around water, 3) recognize a person at risk of drowning and determine the next best course of action, 4) demonstrate three different methods for in-water c-spine stabilization in the case of a possible cervical injury, 5) evaluate and treat a patient after submersion injury, 6) appropriately place a tourniquet for hemorrhage control, and 7) apply a splint to immobilize skeletal injury.
EDUCATIONAL METHODS
A group of 16 resident learners received a thirty-minute introduction discussion (with open discussion) regarding water safety, basic water rescue methods, and submersion injury pathophysiology. They then progressed through three stations designed to emphasize select skills and knowledge related to submersion injury management, water rescue, and tourniquet and splint placement.
RESEARCH METHODS
Participants completed a six-item questionnaire after the event designed to help gage participant comfort level of treatment, management, and experience regarding water safety, drowning, and related traumatic emergencies. Each item was ranked from 0 for "strongly disagree" to 10 for "strongly agree." Total mean scores before and after were compared.
RESULTS
Sixteen individuals participated in the sessions and survey. The total mean score for the six-item analysis increased following the workshop (26.3 before versus 46.9 after, p = 0.001). The positive improvement in all categories indicated increased comfort in the topics of the small group sessions, with the largest improvement in the question about comfort in effectively evaluating and treating a patient presenting to the ED after a submersion injury.
DISCUSSION
Utilizing discussions and hands-on group sessions increased residents' perceived learning. This model can be applied to an extensive number of wilderness medicine topics for learners of all levels. For individuals with time-restrictive schedules, this model is an efficient mode of learning and teaching drowning and injury management skills with the potential for further topics and future courses.
TOPICS
Wilderness medicine, water safety, pathophysiology of drowning, in-water rescues, in-water cervical spine stabilization, management of drowning in the ED, splinting, tourniquets.

Meta-Analysis Review
Drowning is a significant global cause of unintentional injury fatalities, and accurate forensic diagnosis of drowning remains a challenge due to the nonspecific nature of post-mortem findings obtained through classical autopsy methods. Our manuscript addresses this issue by focusing on the emerging use of paranasal sinus fluid as a valuable tool in determining the cause of death, specifically in distinguishing drowning from non-drowning cases. The study provided a comprehensive summary of available evidence from observational studies that compared findings in the paranasal sinuses between drowning and non-drowning victims, analyzing parameters such as the presence of fluid, fluid volume, and density. The study encompassed a total of 14 selected studies involving 1044 subjects and utilized rigorous risk of bias assessment and data synthesis techniques. The meta-analysis demonstrated a strong association between the presence of fluid in the paranasal sinuses and drowning (OR = 17.1; 95% CI 7.2 to 40.5; p < 0.001). In addition, drowning victims had a significantly greater volume of fluid (SMD = 0.8; 95% CI 0.5 to 1.2; p < 0.001) and lower fluid density (SMD = -1.4; 95% -2.5 to -0.4; p = 0.008) compared to non-drowning cases. The results support the utility of paranasal sinus fluid analysis as a valuable diagnostic method in cases where drowning is suspected but cannot be definitively confirmed through traditional approaches.
