Follow up of prospective validation of an abbreviated bedrest protocol in the management of blunt spleen and liver injury in children

Objective: Current APSA recommendations for blunt spleen/liver injury (BSLI) entail bedrest equal to grade of injury plus one. We reported our experience 3 years ago with a prospectively implemented abbreviated protocol, one concern of which was that more numbers would be needed to support the safety of such a protocol. We are now reporting the final experience with this protocol as we move forward with further investigation. Methods: Following IRB approval, data were collected prospectively in all patients with BSLI up to 8 weeks after discharge. There were no exclusion criteria, and patient accrual was consecutive. Bedrest was restricted to one night for Grade I & II injuries and two nights for Grade >= III. Results: Between 11/2006 and 10/2012, 249 patients were admitted with BSLI. Mean age and weight were 10.3 +/- 4.8 years and 40.1 +/- 19.8 kg, respectively. Injuries included isolated spleen in 130 (52%), liver only in 107 (43%), and both in 12 (5%). One splenectomy was required for a grade V injury. Transfusions were used in 40 patients (16%), with 28 (11%) due to the injured solid organ. Bedrest for solid organ injury was applicable to 199 patients (80%), for which the mean grade of injury was 2.7 +/- 1.0 and mean bedrest was 1.6 +/- 0.6 days, resulting in 2.5 +/- 1.9 days of hospitalization. The need for bedrest was the limiting factor for length of stay in 155 patients (62%), for which mean grade of injury was 2.5 +/- 1.0 and mean bedrest was 1.6 +/- 0.6 days, resulting in 1.7 +/- 0.8 days of hospitalization. There were 4 deaths, 3 from brain injury and 1 from grade V liver injury. There were no patients readmitted for complications of solid organ injury. Conclusions: These data further validate that an abbreviated protocol of one night of bedrest for grade I and II injuries and two nights for grade >= III can be safely employed, resulting in dramatic decreases in hospitalization compared to the current APSA recommendations.
