open book fracture
Unstable pelvic ring injury with anterior separation resembling an opened book when viewed on X-ray.
evisceration
Protrusion of abdominal contents through a traumatic defect in the abdominal wall.
exploratory laparotomy
Surgical opening of the abdomen to investigate and treat suspected intra-abdominal injury or pathology.
exsanguination
Severe blood loss leading to circulatory failure and potential death.
fasciotomy
Surgical incision through fascia to relieve compartment pressure and restore tissue perfusion.
FAST exam
Focused Assessment with Sonography in Trauma, an ultrasound protocol to detect free fluid in trauma patients.
flail chest
Chest wall injury where multiple adjacent rib fractures create a free-floating segment that moves paradoxically with res...
focused abdominal sonography
Point-of-care ultrasound examination used to detect free intraperitoneal fluid in trauma patients.
Focused Assessment with Sonography for Trauma
A rapid ultrasound examination used to detect free fluid in the abdomen and pelvis of trauma patients.
Glasgow Coma Scale
A standardized neurological assessment tool measuring eye opening, verbal response, and motor response in brain-injured...
grade V splenic injury
The most severe classification of splenic trauma involving complete organ disruption.
hematoma evacuation
Surgical removal of accumulated blood to relieve pressure and prevent further tissue damage.
hemodynamic instability
Abnormal blood pressure, heart rate, or circulation indicating cardiovascular compromise.
hemopneumothorax
The presence of both blood and air in the pleural space, commonly seen in chest trauma.
hemorrhagic shock
Life-threatening condition resulting from severe blood loss leading to inadequate tissue perfusion and oxygen delivery.
hemostasis
The process of stopping bleeding through clot formation or surgical intervention.
hemothorax
Accumulation of blood in the pleural space, commonly from chest trauma or iatrogenic injury.
hypotensive episode
A documented period of systolic blood pressure below 90 mmHg in trauma patients, serving as a critical marker for hemorr...
hypotensive resuscitation
Fluid management strategy that maintains lower blood pressure to reduce bleeding in trauma patients.
Injury Severity Score
Standardized scoring system that assigns numerical values to anatomical injuries for trauma assessment.
intracranial pressure
The pressure within the skull, elevated levels of which can cause brain injury and require urgent intervention.
intraosseous access
Emergency vascular access technique involving insertion of a needle through bone cortex into the medullary cavity.
ISS
Anatomical scoring system used to assess overall injury severity in trauma patients.
laparoscopic exploration
Minimally invasive surgical technique using a camera to examine the abdominal cavity for trauma-related injuries.
lethal triad
The combination of hypothermia, acidosis, and coagulopathy that develops in severely injured trauma patients.
