Nockels, Valentine Pascale, Phanor L. Perot Jr., Joseph Piepmeier, Volker K. H. Sonntag, Franklin Wagner, Jack E. Wilberger, H. Richard Winn and Wise Young

Object. A randomized double-blind clinical trial was conducted to compare neurological and functional recovery and morbidity and mortality rates 1 year after acute spinal cord injury in patients who had received a standard 24-hour methylprednisolone regimen (24MP) with those in whom an identical MP regimen had been delivered for 48 hours (48MP) or those who had received a 48-hour tirilazad mesylate (48TM) regimen.

Methods. Patients for whom treatment was initiated within 3 hours of injury showed equal neurological and functional recovery in all three treatment groups. Patients for whom treatment was delayed more than 3 hours experienced diminished motor function recovery in the 24MP group, but those in the 48MP group showed greater 1-year motor recovery (recovery scores of 13.7 and 19, respectively, p = 0.053). A greater percentage of patients improving three or more neurological grades was also observed in the 48MP group (p = 0.073). In general, patients treated with 48TM recovered equally when compared with those who received 24MP treatments. A corresponding recovery in self care and sphincter control was seen but was not statistically significant. Mortality and morbidity rates at 1 year were similar in all groups.

Conclusions. For patients in whom MP therapy is initiated within 3 hours of injury, 24-hour maintenance is appropriate. Patients starting therapy 3 to 8 hours after injury should be maintained on the regimen for 48 hours unless there are complicating medical factors.

Methylprednisolone or naloxone treatment after acute spinal cord injury: 1-year follow-up data

Results of the second National Acute Spinal Cord Injury Study

Michael B. Bracken, Mary Jo Shepard, William F. Collins Jr., Theodore R. Holford, David S. Baskin, Howard M. Eisenberg, Eugene Flamm, Linda Leo-Summers, Joseph C. Maroon, Lawrence F. Marshall, Phanor L. Perot Jr., Joseph Piepmeier, Volker K. H. Sonntag, Franklin C. Wagner Jr., James L. Wilberger, H. Richard Winn and Wise Young

✓ The 1-year follow-up data of a multicenter randomized controlled trial of methylprednisolone (30 mg/kg bolus and 5.4 mg/kg/hr for 23 hours) or naloxone (5.4 mg/kg bolus and 4.0 mg/kg/hr for 23 hours) treatment for acute spinal cord injury are reported and compared with placebo results. In patients treated with methylprednisolone within 8 hours of injury, increased recovery of neurological function was seen at 6 weeks and at 6 months and continued to be observed 1 year after injury. For motor function, this difference was statistically significant (p = 0.030), and was found in patients with total sensory and motor loss in the emergency room (p = 0.019) and in those with some preservation of motor and sensory function (p = 0.024). Naloxone-treated patients did not show significantly greater recovery. Patients treated after 8 hours of injury recovered less motor function if receiving methylprednisolone (p = 0.08) or naloxone (p = 0.10) as compared with those given placebo. Complication and mortality rates were similar in either group of treated patients as compared with the placebo group. The authors conclude that treatment with the study dose of methylprednisolone is indicated for acute spinal cord trauma, but only if it can be started within 8 hours of injury.
