Visual examination for blunt abdominal trauma.

Abstract

Visualization of the peritoneal cavity to determine the presence of free blood is desirable to diagnose the condition of a patient who has suffered blunt abdominal trauma. Four-quadrant tap plus peritoneal lavage is reliable but the irrigant fluid may return only slightly pink or not return at all. In the Kansas University Medical Center emergency department, 26 Needlescopic examinations have been tried, with 92% accuracy and two false positive results. The Needlescope procedure is described.
