Safety of early mobilization of patients with blunt solid organ injuries.

BACKGROUND Many surgeons believe that early mobilization of patients with blunt solid organ injuries increases the risk of delayed hemorrhage. OBJECTIVE To determine whether there is an association between the day of mobilization and rates of delayed hemorrhage from blunt solid organ injuries. DESIGN Retrospective cohort study. Univariate and multivariate analyses were performed to determine the association of mobilization with delayed hemorrhage of a solid organ requiring laparotomy. SETTING Level I trauma center. PATIENTS Adults with blunt renal, hepatic, or splenic injuries were identified from a trauma registry. MAIN OUTCOME MEASURES Medical records were used to determine the day of mobilization and to identify patients with delayed hemorrhage requiring laparotomy. RESULTS Four hundred fifty-four patients with blunt solid organ injuries were admitted to the hospital for nonoperative management. Failure rates of nonoperative management were 4.0%, 1.0%, and 7.1% for renal, hepatic, and splenic injuries, respectively. No patients with renal or hepatic injuries failed secondary to delayed hemorrhage. Ten patients (5.5%) with splenic injuries failed secondary to delayed hemorrhage. Eighty-four percent of patients with renal injuries, 80% with hepatic injuries, and 77% with splenic injuries were mobilized within 72 hours of admission. Day of mobilization was not associated with delayed splenic rupture in multivariate analysis (odds ratio, 0.97; 95% confidence interval, 0.90-1.05). CONCLUSIONS The timing of mobilization of patients with blunt solid organ injuries does not seem to contribute to delayed hemorrhage requiring laparotomy. Protocols incorporating periods of strict bed rest are unnecessary.
