Fat embolism involves:
Release of Fat Particles: Typically from long bone fractures or orthopedic procedures where fat globules enter the bloodstream.
Obstruction: Fat particles can lodge in small blood vessels, particularly in the lungs, brain, or other organs.
Inflammatory Response: The immune system reacts to the presence of fat particles, causing inflammation and potentially affecting organ function.
Complications: Severe cases can lead to respiratory distress syndrome (ARDS), neurological symptoms, or multi-organ dysfunction.
Clinical Evaluation
Symptoms: Assessment of symptoms such as shortness of breath, confusion, petechiae (small red spots), and fever.
Physical Examination: Examination findings may include rapid breathing, decreased oxygen levels, and neurological deficits.
Diagnostic Tests: Imaging studies such as chest X-ray or CT scan to detect fat emboli in the lungs, and blood tests to assess oxygenation and organ function.
Sudden onset of shortness of breath.
Confusion or altered mental status.
Petechiae (small red or purple spots) on the skin, typically on the chest or upper body.
Fever.
Rapid heartbeat (tachycardia) and decreased blood oxygen levels.
Management focuses on supportive care and preventing complications:
Oxygen Therapy: Supplemental oxygen to improve oxygenation of the blood.
Fluid Management: Intravenous fluids to maintain blood pressure and organ perfusion.
Respiratory Support: Mechanical ventilation if respiratory distress is severe.
Monitoring: Close monitoring of oxygen levels, organ function, and neurological status.
Preventive Measures: Early mobilization after surgery to reduce the risk of fat embolism in high-risk patients.
