Complications associated with the prophylactic use of methylprednisolone during surgical stabilization after spinal cord injury

Abstract

Object: The authors attempted to determine if there is a significant relationship between the incidence of medical complications and the prophylactic use of methylprednisolone (MP) during spine surgery in patients with acute spinal cord injury (SCI) who had already received MP on hospital admission (typically in the setting of an Emergency Room/Trauma Center).

Methods: The authors studied 73 patients with acute SCI who were admitted to the hospital for at least 7 days postinjury. All patients 1) received a 24-hour regimen of MP in the acute period of hospitalization; and 2) underwent surgery to stabilize the spine and/or decompress the spinal cord. Patients were separated into two groups on the basis of whether they received additional MP therapy during spine surgery. A chart review was conducted retrospectively to determine the incidence of complications up to 6 weeks postinjury. Muscle strength and American Spinal Injury Association grades were determined prospectively throughout the follow-up period. In patients who received two courses of MP following acute SCI (one at initial hospitalization and one during surgery), a significantly increased probability of complications was demonstrated compared with those who received no MP therapy during surgery. This was particularly evident when the incidences of serious complications were compared.

Conclusions: Prophylactic use of MP as a neuroprotective agent during spine surgery in patients with acute SCI should be avoided in those in whom MP was administered on admission to the hospital.
