Against the backdrop of the Russia-Ukraine Conflict in 2022, this article reviews the characteristics of traumatic hemorrhage in modern warfare spanning the past century. It investigates several types of tourniquets used by the Russian and Ukrainian armed forces, including limb tourniquets and junctional tourniquets recommended by the Committee on Tactical Combat Casualty Care, tourniquets employed by the Armed Forces of the Russian Federation, and those used by the Armed Forces of Ukraine in the Russia-Ukraine Conflict. The analysis is conducted from perspectives, including the structure, usage methods, and limitations of different tourniquets. Additionally, the article synthesizes the research progress on tourniquets from 3 angles: battlefield adaptability, the impact of tourniquet application methods on patient outcomes, and training in tourniquet usage, offering insights from our team's perspective.

Aviation medicine safeguards flight safety by addressing three critical areas: managing physiological challenges of the aviation environment, preventing in-flight medical incapacitation and ensuring psychological fitness for flight. The field adopts occupational medicine's hierarchy of risk control to mitigate physiological risks in the operating environment, while employing systematic medical screening with tailored standards based on operational requirements to reduce the likelihood of in-flight incapacitation. A comprehensive approach incorporating mental health education, support systems and regular monitoring helps prevent psychological incapacitation. Recent data from the Singapore Changi Aeromedical Centre reveal that ophthalmological, otolaryngological and respiratory conditions are the primary causes of medical disqualification during air force pilot screening, reflecting the unique physiological demands of military aviation. This review emphasises the ongoing challenge of balancing rigorous medical standards with maintaining an adequate pilot recruitment pool, while highlighting the need for evidence-based approaches to aeromedical assessment and certification.
