Changes of procalcitonin level in multiple trauma patients

Area of Science:

• Trauma pathophysiology
• Biomarker research
• Critical care medicine

Background:

• The pathophysiology of multiple trauma complications is not fully understood.
• Inflammatory mediators are suspected to play a crucial role in severe trauma outcomes.
• Procalcitonin (PCT) is investigated as a potential prognostic marker.

Purpose of the Study:

• To assess the prognostic value of procalcitonin (PCT) levels in multiple trauma patients.
• To correlate PCT levels with trauma severity and patient outcomes.
• To determine if PCT can predict the development of complications.

Main Methods:

• Prospective study of 45 multiple trauma patients (aged 18-70).
• PCT levels measured via enzyme-linked immunoassay at multiple time points.
• Patients categorized into three groups based on injury type (with/without CNS injury).

Main Results:

• Initial PCT levels were below 0.5 ng/mL across all trauma types.
• A significant PCT increase was observed within 24 hours in all groups.
• Highest PCT levels were in trauma patients without CNS injury; higher PCT correlated with mortality and longer surgery duration.

Conclusions:

• Sustained or repeatedly elevated PCT levels post-trauma are strong indicators of developing complications.
• PCT elevation can signal complications earlier than clinical manifestations.
• PCT serves as a valuable early warning marker for adverse events in trauma patients.
