Tube Thoracostomy Management in the Combat Wounded

Area of Science:

• Trauma Surgery
• Thoracic Surgery
• Critical Care Medicine

Background:

• Tube thoracostomy (TT) is crucial for managing chest trauma.
• Complications like pneumonia (PNA) and retained hemothorax (RH) can arise.
• Understanding risk factors is vital for improving patient outcomes.

Purpose of the Study:

• To characterize the management of combat injury tube thoracostomies.
• To identify risk factors for PNA and RH following TT placement.
• To inform strategies for reducing complication incidence.

Main Methods:

• Retrospective analysis of 115 patients with 173 TT placements for combat injuries.
• Data collected on injury characteristics, TT management, and outcomes.
• Multivariable analysis to determine independent risk factors for PNA and RH.

Main Results:

• Pneumonia incidence was 27%, retained hemothorax 9.6%.
• Increased ventilation duration was linked to higher PNA rates.
• Bilateral TT placement and higher injury severity scores were associated with PNA in intubated patients (≤8 days).
• Number of TTs placed correlated with retained hemothorax risk.

Conclusions:

• Ventilation duration is a key risk factor for PNA post-TT.
• Bilateral TTs and injury severity increase PNA risk in specific patient groups.
• The number of TTs placed is a risk factor for RH.
• Further research needed to identify modifiable risk factors for PNA and RH.
