• Adrenal insufficiency
• Neurogenic shock
• Spinal cord injury

BACKGROUND: Adequate adrenal response is fundamental for the maintenance of physiological homeostasis in the setting of trauma and severe illness. Patients with neurogenic shock are at risk of severe consequences if adrenal insufficiency (AI) is not rapidly identified and treated.
OBJECTIVE: To analyze the incidence of AI in patients with acute cervical spinal cord injury and its effect on in-hospital complications.
METHODS: The medical records of patients older than 18 years who were admitted to the adult neurosurgery service at the University District Hospital as the result of neurogenic shock after acute cervical spinal cord injury from January 2004 to December 2009 were reviewed retrospectively.
RESULTS: One hundred ninety-nine patients were admitted with acute cervical spinal cord injury. A total of 37 patients met the pre-established criteria for neurogenic shock. The incidence of AI in patients with neurogenic shock was 22%. The average random cortisol was 9.3 mu g/dL in patients with AI versus 29.2 mu g/dL in non-AI. The presence of AI was positively correlated with complications and an increase in the risk of intubation (P = 0.01 and P = 0.002). The 30-day mortality rate in patients with AI was 13% compared with the 3% in the non-AI group (P = 0.39).
CONCLUSIONS: Adrenal insufficiency is a poorly recognized complication in patients with acute cervical spinal cord injury and its aggressive treatment is of utmost importance to avoid further neurological injury.
