This study is the first to describe the incidence of organ dysfunction and failure in patients with isolated acute traumatic cervical SCI using validated organ system dysfunction scores. Respiratory, cardiovascular, neurologic, renal, hepatic, and hematologic dysfunction occurred commonly both on admission and over the ICU stay. Respiratory, cardiovascular, and neurologic failure were frequently found, while renal, hepatic, and hematologic failures were uncommon. Multiple organ failure occurred in the majority of patients. ASIA motor score and AIS were found to strongly correlate with the development of organ dysfunction and failure. Level of injury should be used with caution when describing the risk of complications and the need for medical interventions.
