Current role of methylprednisolone in the treatment of acute spinal cord injury

High doses of methylprednisolone (MPSS) came into use as part of a therapeutic protocol for acute spinal cord injuries following the published results from the NASCIS II study in 1992; they soon became a standard of care around the world. However, the results of this study have been critically reviewed and questioned by many authors since the beginning. The major argument is based on the fact that its effectiveness in reducing post-injury neurological damage has not been conclusively proved; in addition, there has been increasing evidence of serious side effects of steroids administered at high doses. In the Czech Republic, as part of pre-hospital care, MPSS according to the NASCIS II (or NASCIS III) protocol is used in all regional centres of emergency medical service. In the Czech spinal surgery centres involved in treating acute spinal cord injuries, there are 19 of them, attitudes towards the use of MPSS vary. In 16% of the centres a certainty of its beneficial effect is still maintained, faith in its effect together with fear of a "non-lege artis" procedure is the reason for MSPP use in 21%, and the fear of sanctions only leads to its use in 63% of the centres. There is no standard practice in application of the NASCIS II and NASCIS III protocols and no standard exclusion criteria exist. The two protocols are used equally, and one institution has its own modification. The recommended MPSS dose is administered with no exception in 63% of the centres; dose adjustment is employed according to the form of spinal cord lesion in 11%, the level of spinal cord injury in 5%, associated diseases in 16% and patient age in 11% of the spinal surgery centres. After the results of studies on MPSS administration in acute spinal cord injury have been analysed, many medical societies have changed their recommendations. In view of later relevant publications it is no longer possible to regard MPSS administration as a standard of cure for acute spinal cord injury. Current evidence suggests that MPSS administration in a 24-hour regimen after an initial dose given within 8 hours of injury is the therapeutic procedure that needs individual consideration in each patient according to their state of health and potential complications. MPSS administration at an interval longer than 8 hours after injury and for more than 24 hours is not justified, nor is it justified to use a high MPSS dose at the place of injury by an emergency ambulance crew.
