Age should not be a consideration for nonoperative management of blunt splenic injury

Background: Operative management of blunt splenic injury is recommended for adults greater than or equal to 55 years. Because this is not our practice, we did a retrospective review to compare outcomes of patients greater than or equal to 55 years old versus patients < 55 years old. Methods: During a 5-year period ending in July of 1998, 461 patients (3%) admitted to our Level I trauma center had a blunt splenic injury. Eighty-six patients (19%) died within 24 hours of massive injuries, leaving 375 patients for evaluation. Data were obtained from our trauma registry and medical records. Results: A total of 29 patients (8%) were greater than or equal to 55 years old (mean age, 67 +/- 2 Sears; mean injury severity score [ISS] 25 +/- 2), Of these, 18 patients (62%) underwent nonoperative management (NOM). A total of 346 patients (92%) were < 55 years old (mean age, 28 =/- 0.6; mean ISS, 20 +/- 1). Of these, 198 patients (57%) underwent NOM. The failure rate mas not different between the two age groups (17% vs. 14%). However, the ISS and mortality rate were significantly higher in the older age group that failed (ISS, 29.3 +/- 2.6 vs. 19.5 +/- 2.1; mortality: 67% vs. 4%). None of the deaths could be attributed to splenic injury. Conclusion: Adults greater than or equal to 55 years old with blunt splenic injury are successfully treated by NOM. Although older adults had significantly greater injuries, they had similar failure rates of NOM when compared with younger adults. Older adults had significantly higher mortality, but this,vas not a result of their splenic injury. Therefore, age should not be a criteria for NOM of blunt splenic injury.
