Unlike classic heat stroke, EHS can occur in young, healthy individuals and in temperate climates, when heat production exceeds the body's ability to dissipate heat. Rising global temperatures and increased participation in endurance events are contributing to a growing incidence of EHS. Early recognition and rapid cooling are essential to prevent multi-organ failure and death. Whole-body cold-water immersion is the gold standard treatment, and the principle of “cool first, transport second” is key to improving survival. In-hospital care focuses on continued cooling when necessary and managing complications such as acute kidney injury, coagulopathy, liver dysfunction, and neurological impairment. This review provides intensivists with practical guidance on the pathophysiology, diagnosis, and management of EHS. Given their expertise in critical illness and involvement in prehospital and emergency care, intensivists play a pivotal role in early intervention and reducing morbidity and mortality. As EHS incidence rises, increased awareness and preparedness are essential to ensure timely, effective treatment and improve patient outcomes.</div></div>","PeriodicalId":15451,"journal":{"name":"Journal of critical care","volume":"89 ","pages":"Article 155134"},"PeriodicalIF":3.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144195741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Achieving consistency across teams remains a challenge. This study explores how team dynamics and communication influence patient discussions during ICU ward rounds, using sociograms. Method: Observations of ward rounds were conducted in two ICUs at a tertiary hospital in South Africa. Field notes detailed contextual descriptions, team interactions, and activities. Sociograms mapped and quantified communication episodes and team dynamics. Reflexive feedback promoted team self-assessment on communication practices. Data were thematically analysed, complemented by descriptive statistics. Results: Fifty-four hours of observations, covering 273 patient discussions, generated 38 sociograms and documented 1900 communication episodes. Consultants (43 %,821/1900) and registrars (44 %,835/1900) led discussions, with registrars providing structured updates, including on infection care. Infection care constituted nearly one-third of discussions, however input from nurses, pharmacists, and microbiologists was notably limited despite their active roles in infection-related care. Clear, direct communication correlated with task documentation, while unclear communication led 77 % of tasks undocumented. Infection-related actions were clearly communicated in 93 % of cases. Positioning, side discussions, and interruptions affected communication clarity and focus. The process and reflexivity shifted the view of ward rounds, reframing them as adaptable tools for improving patient care. Discussion: Mapping and quantifying interactions shows the distribution of power and influences in patient discussions. Sociograms and reflexive practices aid self-assessment of interactions to improve team dynamics. Structured communication strategies that include key players, can enhance dynamics, infection care and patient outcomes.</div></div>","PeriodicalId":15451,"journal":{"name":"Journal of critical care","volume":"89 ","pages":"Article 155127"},"PeriodicalIF":3.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
