Abstract. Severe trauma is one of the leading causes of death worldwide, particularly in patients under the age of 45. Effective early management in the hospital setting is critical for improving survival rates and reducing long-term disability. This article provides an in-depth overview of first aid strategies and emergency clinical protocols applied to patients with life-threatening trauma, based on internationally accepted trauma care guidelines such as Advanced Trauma Life Support (ATLS) and Damage Control Resuscitation (DCR).
