Summary

Emergency abdominal sonography is a reliable tool for detecting internal injuries in unstable patients with blunt abdominal trauma. This fast, portable method accurately identifies free intraperitoneal fluid, guiding surgical decisions.

Area of Science:

  • Emergency medicine
  • Diagnostic imaging
  • Trauma surgery

Background:

  • Unstable patients with blunt abdominal trauma need rapid assessment for potential laparotomy.
  • Detecting free intraperitoneal fluid via ultrasonography in the resuscitation area can indicate intraabdominal injury.

Purpose of the Study:

  • To evaluate the utility of emergency abdominal sonography in blunt abdominal trauma patients.
  • To compare the effectiveness of ultrasonography with diagnostic peritoneal lavage.

Main Methods:

  • A prospective study was conducted on 54 acutely injured patients.
  • Emergency sonography was performed before diagnostic peritoneal lavage in the resuscitation area.

Main Results:

  • Ultrasonography demonstrated 87% sensitivity and 100% specificity for detecting free intraperitoneal fluid.

  • The overall accuracy of ultrasonography in identifying fluid was 96%.

    • Conclusions:

    • Ultrasonography is a reliable method for emergent evaluation of blunt abdominal trauma.
    • It can replace diagnostic peritoneal lavage as an initial indicator for surgical intervention.
