ObjectiveNon-operative management of blunt splenic injury in adults has been applied increasingly at the end of the last century. Therefore, the lifelong risk of overwhelming post-splenectomy infection has been the major impetus for preservation of the spleen. However, the prevalence of posttraumatic infection after splenectomy in contrast to a conservative management is still unknown. Objective was to determine if splenectomy is an independent risk factor for the development of posttraumatic sepsis and multi-organ failure.Methods13,433 patients from 113 hospitals were prospective collected from 1993 to 2005. Patients with an injury severity score > 16, no isolated head injury, primary admission to a trauma center and splenic injury were included. Data were allocated according to the operative management into 2 groups (splenectomy (I) and conservative managed patients (II)).ResultsFrom 1,630 patients with splenic injury 758 patients undergoing splenectomy compared with 872 non-splenectomized patients. 96 (18.3%) of the patients with splenectomy and 102 (18.5%) without splenectomy had apparent infection after operation. Additionally, there was no difference in mortality (24.8% versus 22.2%) in both groups. After massive transfusion of red blood cells (> 10) non-splenectomy patients showed a significant increase of multi-organ failure (46% vs. 40%) and sepsis (38% vs. 25%).ConclusionsNon-operative management leads to lower systemic infection rates and mortality in adult patients with moderate blunt splenic injury (grade 1-3) and should therefore be advocated. Patients with grade 4 and 5 injury, patients with massive transfusion of red blood cells and unstable patients should be managed operatively.
(1) independently of the initially good GCS, a high percentage of patients suffered from severe intracranial lesions and (2) besides the GCS only the patients'age and primary assessment by the emergency physician were useful for identifying patients at risk for an intracranial lesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
