BackgroundBlunt pericardial effusion (BPE) in trauma patients can be suggestive of injuries to the heart or great vessels. Surgical exploration is the mainstay of management; however, the effectiveness of non-operative management in this patient group remains unclear.MethodsPatients presenting with BPE in the trauma registry system at our level I trauma center were reviewed. Patients with and without cardiovascular (CVS) injury were compared to identify predictors for CVS injury and to understand the factors related to the requirement for surgery. Patients with and without CVS injury who presented with stable hemodynamics and initially received conservative management were also compared.ResultsThirty patients were enrolled in the study with a mean age of 53.2 (standard deviation (SD) 18.0) years and a mean injury severity score (ISS) of 26.7 (SD 9.0). Eleven patients presented with systolic blood pressure (SBP)<100mmHg, and immediate surgical intervention was performed. Eight patients had evidence of CVS injury (73%). Nineteen patients had stable hemodynamics and initially received conservative treatment. Of these, twelve patients received further surgical interventions, and only three had evidence of CVS injury (16%, 3/19).Comparisons of individuals with and without CVS injury revealed that the SBP on presentation was higher in patients without CVS injury than in those with CVS injury (132.7 (SD 41.3) mmHg vs. 95.6 (SD 21.1) mmHg). Clinically irrelevant differences between the two groups were observed for the creatine kinase (CK)-MB level, the troponin I level, the presence of an echocardiography tamponade sign, associated chest trauma and ISS. No remarkable predictors for CVS injury were found in hemodynamically stable patients.ConclusionNon-operative management can be considered for patents with traumatic BPE and stable hemodynamics; however, this approach must be performed at an institution with adequate facilities and well-trained staff.
