This study evaluated deep venous thrombosis (DVT) prophylaxis in trauma patients. Low molecular weight heparin and risk assessment showed promise, supporting a larger clinical trial for effective DVT prevention.

Area of Science:

  • Trauma surgery
  • Vascular medicine
  • Diagnostic imaging

Background:

  • Thromboembolism is a significant risk for high-risk trauma patients.
  • Effective prophylaxis and early detection of deep venous thrombosis (DVT) are crucial.

Purpose of the Study:

  • To assess the feasibility of a study design for DVT prophylaxis in trauma patients.
  • To evaluate current prophylaxis methods, a risk assessment scale, and duplex ultrasound for DVT detection.

Main Methods:

  • Patients were randomized to various prophylaxis strategies (heparin, compression devices).
  • Serial color-flow duplex ultrasound was used to detect DVT over 4 weeks.
  • Pulmonary angiograms were performed for suspected pulmonary embolism.

Main Results:

  • DVT occurred in 43% of patients, higher in older individuals.
  • Color-flow duplex effectively detected proximal and distal thrombi.
  • The Risk Assessment Profile for Thromboembolism (RAPT) scale identified high-risk patients, but DVT occurrence was not correlated with RAPT score magnitude.

Conclusions:

  • The RAPT score can identify patients at high risk for DVT.
  • Low molecular weight heparin may offer an advantage in DVT prevention.
  • These findings support the need for a powered randomized clinical trial on DVT prophylaxis.
