Abstract

BACKGROUND: The use of Focused Assessment with Sonography for Trauma (FAST) in combination with computed tomography (CT) has become the mainstay of diagnostic workup in patients with suspected intraabdominal hemorrhage (IAH). However, diagnostic peritoneal aspiration (DPA) can be an important adjunct in hemodynamically unstable patients. The aim of this study was to evaluate the utility and diagnostic accuracy of DPA in detecting IAH.

METHODS: Retrospective analysis of all patients who presented to the LAC+USC Medical Center and underwent evaluation with DPA between January 2010 and December 2016. Intraoperative, CT, and autopsy findings were used as gold standards in determining the diagnostic accuracy of DPA for the detection of IAH.

RESULTS: A total of 73 consecutive patients were included in the study. The median age was 42 years (interquartile range [IQR]: 25-56), median injury severity score was 29 (IQR: 21-41), and 82.2% sustained blunt trauma. The most common indications for DPA were hemodynamically unstable patients with suspected IAH and patients with return of spontaneous circulation following resuscitative thoracotomy. Overall, the positive and negative predictive values of DPA were 89.4% and 88.9%, respectively. In 14 cases (19.2%), DPA correctly identified false positive/negative FAST results.

CONCLUSION: Our data suggest that DPA has high diagnostic yield for IAH. The use of DPA should be considered in unstable patients with inconclusive FAST results who cannot safely be evaluated with CT.
