Association between cooling temperature and outcomes of patients with heat stroke
This study explored the relationship between body temperature and adverse outcomes in patients with heat stroke to identify the optimal target body temperature within the first 24  h. This retrospective, multicentre study enrolled 143 patients admitted to the emergency department and diagnosed with heat stroke. The primary outcome was the in-hospital mortality rate, while secondary outcomes included the presence and number of damaged organs and neurological sequelae at disch arge. A body temperature curve was built using a generalized additive mixed model, and the association between body temperatures and outcomes was est...

Cooling modality effectiveness and mortality associated with pre-hospital care of exertional heat stroke casualties
Cold water immersion is the gold standard for field treatment of an exertional heat stroke (EHS) casualty. Practical limitations may preclude this method and ice sheets (bed linens soaked in ice water) have emerged as a viable alternative. Laboratory studies suggest that this is an inferior method, however the magnitude of hyperthermia is limited and may under-estimate the cooling rate in EHS casualties.

Cooling Modality Effectiveness and Mortality Associate With Prehospital Care of Exertional Heat Stroke Casualities
Cold-water immersion is the gold standard for field treatment of an exertional heat stroke (EHS) casualty. Practical limitations may preclude this method and ice sheets (bed linens soaked in ice water) have emerged as a viable alternative. Laboratory studies suggest that this is an inferior method; however, the magnitude of hyperthermia is limited and may underestimate the cooling rate in EHS casualties.

Sudden Death in High School Athletes: A Case Series Examining the Influence of Sickle Cell Trait
We present a case series of fatal ECAST in high school athletes aged 14 to 16 years. All 3 athletes experienced collapse during practice sessions with muscle pain or weakness. Upon evaluation at the hospital, the athletes had a significant metabolic acidosis that did not respond as expected to fluid resuscitation. Admitting diagnoses for the athletes included exertional heat stroke or dehydration. All 3 athletes had profound rhabdomyolysis leading to acute renal failure, worsening metabolic acidosis, and hyperkalemia. They rapidly progressed to disseminated intravascular coagulation, multiorgan system failure, and death. T...

Inhalation of 2% Hydrogen Improves Survival Rate and Attenuates Shedding of Vascular Endothelial Glycocalyx in Rats with Heat Stroke
Heat stroke is characterized by excessive oxidative stress and inflammatory responses, both of which are implicated in vascular endothelial glycocalyx shedding and heat-stroke mortality. Although molecular hydrogen has antioxidation and anti-inflammatory potency, its effect on the vascular endothelial glycocalyx in heat stroke has not been examined. Therefore, the aim of this study was to investigate the influence of hydrogen inhalation on the survival and thickness of the vascular endothelial glycocalyx of rats subjected to heat stroke. Altogether, 98 Wistar rats were assigned to the experiments. A heat-controlled chamber...

European Resuscitation Council Guidelines 2021: First aid
The European Resuscitation Council has produced these first aid guidelines, which are based on the 2020 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. The topics include the first aid management of emergency medicine and trauma. For medical emergencies the following content is covered: recovery position, optimal positioning for shock, bronchodilator administration for asthma, recognition of stroke, early aspirin for chest pain, second dose of adrenaline for anaphylaxis, management of hypoglycaemia, oral rehydration solutions for treating exertion-related dehydration, manage...

Risk Factors for the 90-Day Prognosis Of Severe Heat Stroke: a Case-Control Study
Background: Severe heat stroke is a clinical syndrome caused by host stress dysfunction due to heat stress and subsequent life-threatening organ dysfunction. We aimed to explore the early risk factors affecting the 90-day prognosis of severe heat stroke patients. Methods: A case-control study was used to retrospectively analyze the clinical data of 117 severe heat stroke patients admitted to the intensive care unit of the General Hospital of Southern Theater Command from April 2014 to May 2019. The risk factors affecting the 90-day mortality of the patients were analyzed, and subgroup analysis was performed comp...

Heroic, Lifesaving Measures Are Unnecessary When Optimal Cooling Is Provided for Exertional Heat Stroke Victims
As emergency physicians and athletic trainers, we concur with Bursey et  al. that exertional heat stroke (EHS) is a potentially life-threatening emergency requiring rapid reduction of core body temperature (1). We do not dispute that the endovascular cooling initiated for this patient appeared to be lifesaving. However, to consider the failed cooling method (ice sheet application [ISA]) as a “standard cooling measure” is directly in contrast to best practices. The reality is that if proper cooling strategies had been done initially then the need for the invasive in-hospital care would not have been necessary.

First aid cooling techniques for heat stroke and exertional hyperthermia: A systematic review and meta-analysis
Heat stroke is an emergent condition characterized by hyperthermia (>40  °C/>104  °F) and nervous system dysregulation. There are two primary etiologies: exertional which occurs during physical activity and non-exertional which occurs during extreme heat events without physical exertion. Left untreated, both may lead to significant morbidity, are considered a special circumst ance for cardiac arrest and cause of mortality.
