Background  Treatment of blunt splenic injury has changed over the past decades. Nonoperative management (NOM) is the treatment of choice. Adequate patient selection is a prerequisite for successful NOM. Impaired mental status is considered as a relative contra indication for NOM. However, the impact of altered consciousness in well-equipped trauma institutes is unclear. We hypothesized that impaired mental status does not affect outcome in patients with splenic trauma.    Methods  Our prospectively composed trauma database was used and adult patients with blunt splenic injury were included during a 14-year time period. Treatment guidelines remained unaltered over time. Patients were grouped based on the presence (Group GCS: < 14) or absence (Group GCS: 14–15) of impaired mental status. Outcome was compared.    Results  A total of 161 patients were included, of whom 82 were selected for NOM. 36% of patients had a GCS-score < 14 ( N  = 20). The median GCS-score in patients with reduced consciousness was 9 (range 6–12). Groups were comparable except for significantly higher injury severity scores in the impaired mental status group (19 vs. 17,  p  = 0.007). Length of stay (28 vs. 9 days,  p  < 0.001) and ICU-stay (8 vs. 0 days,  p  = 0.005) were longer in patients with decreased GCS-scores. Failure of NOM, total splenectomy rates, complications and mortality did not differ between both study groups.    Conclusion  This study shows that NOM for blunt splenic trauma is a viable treatment modality in well-equipped institutions, regardless of the patients mental status. However, the presence of neurologic impairment is associated with prolonged ICU-stay and hospitalization. We recommend, in institutions with adequate monitoring facilities, to attempt nonoperative management for blunt splenic injury, in all hemodynamically stable patients without hollow organ injuries, also in the case of reduced consciousness.

Nonoperative management of splenic injury in closely monitored patients with reduced consciousness is safe and feasible
