Abstract

Background: Trauma is the leading health concern among young adults. Blunt abdominal trauma (BAT) is the most common type of blunt traumas. BAT patients may prove normal in the initial clinical assessments, but since the time required for an intra-abdominal injury to be clinically apparent is not predictable, deciding when to safely discharge these patients could be a dilemma. The purpose of this study is to determine whether follow-up of the early discharged or further diagnostic assessment of the later discharged BAT patients with normal initial findings reveals any abnormal findings. Methods: Totally, 389 hemodynamically-stable patients suspected of BAT who arrived at the emergency department (ED) of two university hospitals in Tehran from September 2013 to September 2014 were included in this study. Upon arrival at the ED, all subjects underwent abdominal examination and FAST, and were assessed for hematocrit and base deficit levels and presence of hematuria. These assessments were repeated in the patients who were discharged after 6 h, at 6 or 12 h post-arrival. All patients were followed-up after 24 h and one week by phone call. Results: Out of all study participants, 158 patients (40.6%) had normal findings in all initial assessments. These patients were discharged from the ED after a median of 5 h. After one week of follow-up, none of them had any symptom or complication, or had sought medical attention after being discharged from the study hospitals. Out of these patients, 78 patients (49.4%) were discharged after 6 hours by their physician’s decision, and underwent the same diagnostic assessments for the second or third time. None of these assessments revealed any abnormal findings. Conclusions: A combination of normal abdominal exam, normal FAST, normal hematocrit, normal base deficit, and absence of hematuria rules out intra-abdominal injury in BAT patients. It is safe to discharge patients after they prove normal for these assessments. Longer observation and repeated diagnostic assessment of these patients does not yield any new findings, and seems to be unnecessary. © 2016 The Royal Belgian Society for Surgery.
