Early FF leads to greater fluid administration in patients with head injuries. Hypoxemia and hypotension, risk factors for secondary brain injury, may contribute to a poor neurologic outcome after early fixation. Prospective studies evaluating the impact of the timing of FF on head injury are indicated.

Elevated concentrations of urine IFABP correlated with the clinical development of SIRS. Studies to assess the utility of IFABP as a predictor of organ dysfunction and SIRS in the critically ill are warranted.
